What are the best biotin supplements on the market today. How can biotin support hair, skin, and nail health. Which biotin products offer the best value and quality. What factors should you consider when choosing a biotin supplement.

Understanding Biotin: The Essential B Vitamin

Biotin, also known as vitamin B7, is a crucial nutrient that plays a vital role in various bodily functions. But what exactly does biotin do for our body?

Biotin’s primary function is to help convert food into usable energy. It acts as a coenzyme in metabolic processes, breaking down fats, proteins, and carbohydrates. This makes biotin essential for maintaining a healthy metabolism and energy levels.

While biotin deficiency is rare, certain groups may be at higher risk:

• Pregnant and breastfeeding women
• Individuals with alcohol use disorder
• People with biotinidase deficiency, a rare genetic disorder

For most people, a balanced diet provides sufficient biotin. Rich dietary sources include:

• Organ meats (liver, kidney)
• Fish
• Eggs
• Meat
• Nuts and seeds
• Sweet potatoes

The Potential Benefits of Biotin Supplements

While biotin is primarily known for its role in metabolism, it has gained popularity for its potential benefits in other areas. Can biotin supplements really improve hair, skin, and nail health?

The association between biotin and beauty stems from the symptoms of biotin deficiency, which include brittle nails, hair loss, and skin rashes. This has led to the widespread belief that biotin supplements can enhance these attributes in everyone. However, scientific evidence supporting this claim for individuals without a deficiency is limited.

Potential benefits of biotin supplements include:

1. Metabolism support: Biotin helps convert food into energy, potentially aiding in weight management and overall metabolic health.
2. Hair health: While research is inconclusive, some studies suggest biotin may improve hair growth and thickness in people with thinning hair.
3. Nail strength: Biotin supplements may help strengthen brittle nails, though more research is needed to confirm this effect.
4. Skin health: Some people report improvements in skin clarity and texture, but scientific evidence is lacking.

It’s important to note that these benefits are primarily observed in individuals with biotin deficiency. For those with adequate biotin levels, the effects may be less pronounced or nonexistent.

Top Biotin Supplements: A Comprehensive Review

With numerous biotin supplements on the market, choosing the right one can be overwhelming. Here’s a breakdown of some top-rated options to help you make an informed decision:

1. Life Extension Biotin

Price: $
Type: Capsule
Dose: 2,000% of Daily Value (DV)

This vegetarian-friendly, non-GMO supplement is third-party tested by NSF International. While it offers a lower dose compared to other biotin-only supplements, many users report improvements in nail strength. However, some reviewers note that it may take up to a year to see noticeable results.

2. Garden of Life Mykind Organic Plant Collagen Builder

For those seeking an organic option, this supplement combines biotin with other nutrients to support collagen production and overall beauty from within.

3. OLLY Ultra Hair

This biotin supplement is specifically formulated to support hair health, combining biotin with other vitamins and minerals known to promote healthy hair growth.

5. OLLY Undeniable Beauty Gummy

For those who prefer a more palatable option, these gummies offer biotin in a tasty, chewable form, making daily supplementation more enjoyable.

Choosing the Right Biotin Supplement: Key Factors to Consider

When selecting a biotin supplement, several factors should guide your decision:

• Dosage: Biotin supplements often contain much higher doses than the recommended daily intake. While biotin is generally considered safe even at high doses, it’s best to consult with a healthcare professional to determine the right amount for you.
• Form: Biotin supplements come in various forms, including capsules, tablets, gummies, and liquid drops. Choose a form that fits your lifestyle and preferences.
• Additional ingredients: Some supplements combine biotin with other nutrients for comprehensive beauty support. Consider whether you need these additional ingredients or prefer a biotin-only supplement.
• Third-party testing: Look for supplements that have been third-party tested for purity and potency to ensure you’re getting a high-quality product.
• Price: Biotin supplements vary widely in price. While cost shouldn’t be the only factor, it’s important to find a product that fits your budget for long-term use.

The Science Behind Biotin: Separating Fact from Fiction

Despite its popularity, the scientific evidence supporting biotin’s effectiveness for hair, skin, and nail health in non-deficient individuals is limited. Why is there such a disconnect between popular belief and scientific evidence?

The biotin beauty myth largely stems from the observable effects of biotin deficiency. When someone lacks biotin, they may experience hair loss, brittle nails, and skin problems. However, this doesn’t necessarily mean that taking extra biotin will enhance these attributes in people with adequate levels.

Current research on biotin supplementation shows:

• Limited evidence for hair growth: While some small studies suggest biotin may help with hair growth, larger, more robust studies are needed to confirm these effects.
• Inconclusive results for nail health: Some studies show improvements in nail strength with biotin supplementation, but results are mixed.
• Lack of evidence for skin benefits: There’s little scientific support for biotin’s effects on skin health in non-deficient individuals.

It’s crucial to approach biotin supplementation with realistic expectations and to understand that individual results may vary. For those without a deficiency, the benefits may be minimal or nonexistent.

Biotin Safety and Potential Side Effects

While biotin is generally considered safe, even at high doses, it’s important to be aware of potential side effects and interactions. Are there any risks associated with biotin supplementation?

Biotin is water-soluble, meaning excess amounts are typically excreted in urine. This makes toxicity rare, even at high doses. However, some considerations include:

• Interaction with lab tests: High doses of biotin can interfere with certain laboratory tests, potentially leading to false results. This is particularly important for thyroid function tests and cardiac biomarkers.
• Skin reactions: In rare cases, some people may experience skin rashes or acne breakouts when taking biotin supplements.
• Digestive issues: Some individuals report mild digestive discomfort when taking biotin supplements.

To ensure safe supplementation:

1. Consult with a healthcare professional before starting any new supplement regimen.
2. Inform your doctor about biotin supplementation before undergoing any lab tests.
3. Start with a lower dose and gradually increase if needed, monitoring for any adverse reactions.
4. Choose high-quality supplements from reputable manufacturers to minimize the risk of contaminants or impurities.

Maximizing the Benefits of Biotin: Lifestyle and Dietary Considerations

While biotin supplements can be beneficial for some, optimizing your overall lifestyle and diet can enhance their effectiveness. How can you support biotin’s function in your body naturally?

To maximize the potential benefits of biotin, consider the following strategies:

1. Balanced diet: Incorporate biotin-rich foods into your meals, such as eggs, nuts, seeds, and sweet potatoes.
2. Hydration: Proper hydration supports overall health and can contribute to healthier hair, skin, and nails.
3. Stress management: Chronic stress can impact hair and skin health. Implement stress-reduction techniques like meditation or yoga.
4. Adequate sleep: Quality sleep is crucial for overall health and can support the body’s natural regenerative processes.
5. Protection from environmental damage: Use sunscreen and avoid excessive heat styling to protect your hair and skin.

Remember, biotin supplements should complement a healthy lifestyle rather than serve as a magic solution. A holistic approach to health and beauty will likely yield the best results.

The Future of Biotin Research: What’s on the Horizon?

As interest in biotin continues to grow, researchers are exploring its potential benefits beyond metabolism and beauty. What new applications for biotin might we see in the future?

Emerging areas of biotin research include:

• Diabetes management: Some studies suggest biotin may help improve blood sugar control in people with diabetes.
• Neurological health: Researchers are investigating biotin’s potential role in supporting nerve function and possibly alleviating symptoms of multiple sclerosis.
• Cardiovascular health: Preliminary research indicates biotin might play a role in reducing inflammation and supporting heart health.
• Personalized supplementation: Future studies may help identify specific populations or genetic profiles that could benefit most from biotin supplementation.

While these areas show promise, it’s important to note that research is still in early stages. As our understanding of biotin’s functions in the body grows, we may discover new and exciting applications for this versatile vitamin.

In conclusion, biotin supplements can be a valuable addition to your health regimen, particularly if you’re at risk of deficiency. However, it’s crucial to approach supplementation with realistic expectations and a holistic view of health. By combining high-quality supplements with a balanced diet and healthy lifestyle, you can optimize your body’s utilization of biotin and potentially enhance your overall well-being.

Biotin is a B vitamin that your body needs to help convert food breakdown products into useable energy (1).

It’s richest in animal foods, including organ meats, fish, eggs, and meat. However, it’s also found in nuts, seeds, and sweet potatoes (1).

Most people get enough biotin in their diet, so deficiency is rare. However, you may be at increased risk of biotin deficiency if you’re pregnant or breastfeeding, have alcohol use disorder, or have a condition called biotinidase deficiency (1).

Some of the potential benefits of biotin include:

• Metabolism. The major role of biotin is to help metabolize the fatty acids, proteins, and sugars from food into a form that your body can use for energy (1).
• Hair, skin, and nail support. Some of the major symptoms of biotin deficiency include brittle nails and hair, alongside skin concerns, which has led many people to believe that biotin can help improve these areas in anyone. Supplement manufacturers have capitalized on this by including high doses of biotin in “hair, skin, and nails” formulations. However, there’s little evidence that biotin can help improve hair, skin, or nail health in people who don’t have a biotin deficiency (2).

When choosing the best biotin supplements, we looked at the following:

• Indicators of trust. We prioritized products that are third-party tested for purity and potency and made in facilities that adhere to the current good manufacturing practices (CGMPs) set by the Food and Drug Administration (FDA).
• Ingredient quality. We chose products that contain high quality ingredients, with minimal use of fillers and additives.
• Vetting. All the biotin supplements below have been vetted to ensure that they meet Healthline’s medical and business standards.

When taken at high doses, excess B vitamins are typically flushed out via your urine. However, it’s possible that there simply hasn’t been enough research on the potential side effects of taking too much (1).

Here are some things to consider when shopping for a biotin supplement:

• Third-party testing. It’s best to choose a supplement that has undergone third-party testing to ensure quality and purity. Many supplements on this list are third-party tested, and the rest are manufactured in CGMP certified facilities with in-house testing protocols.
• Allergies and dietary needs. Also consider any allergies or dietary considerations you may have. Klaire Labs and Pure Encapsulations offer hypoallergenic biotin supplements, while Garden of Life offers organic, vegan-friendly options.
• Supplement type. As with any supplement, you’ll want to choose the form — softgel, gummy, or liquid — that’s easiest and most convenient for you to take.
• Your goals. If you don’t need to supplement with biotin but are looking to improve the quality of your hair, skin, and nails, choose a supplement specifically formulated for this purpose. It’ll likely contain additional ingredients that support your goals.

Keep in mind that there’s little evidence to support the use of biotin for hair, nail, or skin health. Consuming a healthy, well-rounded diet will do much more for your hair, skin, and nails than taking a supplement.

Biotin supplements can also affect certain lab tests, such as those used to measure thyroid hormones or heart damage, potentially leading to false results. This could lead to the misdiagnosis of serious medical conditions, which could be dangerous and even deadly (1, 3).

As a result, it’s important to talk with a healthcare professional before taking a biotin supplement.

Finally, because all the supplements below contain high amounts of biotin, it’s important not to take more than the manufacturer’s recommended dose.

What are biotin supplements good for?

Biotin supplements are most commonly used to promote healthy hair or nail growth. Some of the symptoms of biotin deficiency are hair loss, skin changes, and brittle nails (1).

However, there’s limited evidence to support this particular use for biotin because most people aren’t deficient in biotin — despite its popularity as a hair, skin, and nails vitamin (12).

However, some populations are at risk of biotin deficiency and may benefit from a supplement, including those with alcohol use disorder, those who are pregnant or breastfeeding, and those with a biotinidase deficiency, which affects how the body metabolizes biotin (1).

How much biotin should I take per day?

The daily Adequate Intake (AI) levels for biotin for adults are as follows (1):

• Men: 30 mcg
• Women: 30 mcg
• Pregnancy: 30 mcg
• Breastfeeding: 35 mcg

The AI levels for biotin are believed to meet the needs of at least 50% of the population, until more research is conducted regarding biotin needs.

Most biotin supplements contain significantly higher amounts than the AI. The supplements on this list provide 830–33,333% of the DV for biotin. Fortunately, there’s no evidence that high doses are directly harmful (1).

However, high doses of biotin can interfere with lab tests by falsely skewing thyroid hormone levels, vitamin D levels, or other results, which could have a significant impact on your medical care (1, 13).

Be sure to let a healthcare professional know if you’re taking a biotin supplement prior to having lab work done.

Are there side effects of taking biotin?

Biotin doesn’t appear to be linked to any notable side effects. Some people report skin rashes or digestive upset after taking a biotin supplement, but there’s currently no research on specific biotin side effects.

Remember, however, that biotin may interfere with lab testing results. Biotin supplements may also interfere with anticonvulsant medications, so make sure to speak with a healthcare professional before taking biotin if you’re on an anticonvulsant (1).

How to tell if you need more biotin?

Biotin deficiency is rare, but if you’re deficient in biotin you may experience (1):

• hair thinning or hair loss
• red, scaly skin rash
• conjunctivitis, or pink eye
• brittle nails
• fatigue
• seizures

If you suspect biotin deficiency, speak with a healthcare professional about confirming it with a blood test.

What happens if you take too much biotin supplement?

Taking too much biotin from supplements may cause falsely high or low thyroid hormone or vitamin D levels. For this reason, it’s important to notify your healthcare professional prior to having bloodwork done if you’re taking biotin or a hair, skin, and nails supplement (1, 13).

How long does a biotin supplement stay in your system?

According to one study, blood biotin level reaches its peak 2–4 hours after taking a biotin supplement. But the study noted that your biotin may still be elevated above normal even at 24 hours after taking a supplement (14).

For this reason, your healthcare professional may ask you to stop taking biotin supplements for 48 hours prior to having bloodwork done (14).

Just make sure to choose a product that’s produced by a reputable manufacturer with a cGMP certified facility and is third-party tested to ensure accuracy and purity.

Considerations

• some reviews note a lack of noticeable benefits
• lower dose of biotin still provides 2,000% of the DV

Here are some things to consider when shopping for a biotin supplement:

• Third-party testing. It’s best to choose a supplement that has undergone third-party testing to ensure quality and purity. Many supplements on this list are third-party tested, and the rest are manufactured in CGMP certified facilities with in-house testing protocols.
• Allergies and dietary needs. Also consider any allergies or dietary considerations you may have. Klaire Labs and Pure Encapsulations offer hypoallergenic biotin supplements, while Garden of Life offers organic, vegan-friendly options.
• Supplement type. As with any supplement, you’ll want to choose the form — softgel, gummy, or liquid — that’s easiest and most convenient for you to take.
• Your goals. If you don’t need to supplement with biotin but are looking to improve the quality of your hair, skin, and nails, choose a supplement specifically formulated for this purpose. It’ll likely contain additional ingredients that support your goals.

Keep in mind that there’s little evidence to support the use of biotin for hair, nail, or skin health. Consuming a healthy, well-rounded diet will do much more for your hair, skin, and nails than taking a supplement.

Biotin supplements can also affect certain lab tests, such as those used to measure thyroid hormones or heart damage, potentially leading to false results. This could lead to the misdiagnosis of serious medical conditions, which could be dangerous and even deadly (1, 3).

As a result, it’s important to talk with a healthcare professional before taking a biotin supplement.

Finally, because all the supplements below contain high amounts of biotin, it’s important not to take more than the manufacturer’s recommended dose.

What are biotin supplements good for?

Biotin supplements are most commonly used to promote healthy hair or nail growth. Some of the symptoms of biotin deficiency are hair loss, skin changes, and brittle nails (1).

However, there’s limited evidence to support this particular use for biotin because most people aren’t deficient in biotin — despite its popularity as a hair, skin, and nails vitamin (12).

However, some populations are at risk of biotin deficiency and may benefit from a supplement, including those with alcohol use disorder, those who are pregnant or breastfeeding, and those with a biotinidase deficiency, which affects how the body metabolizes biotin (1).

How much biotin should I take per day?

The daily Adequate Intake (AI) levels for biotin for adults are as follows (1):

• Men: 30 mcg
• Women: 30 mcg
• Pregnancy: 30 mcg
• Breastfeeding: 35 mcg

The AI levels for biotin are believed to meet the needs of at least 50% of the population, until more research is conducted regarding biotin needs.

Most biotin supplements contain significantly higher amounts than the AI. The supplements on this list provide 830–33,333% of the DV for biotin. Fortunately, there’s no evidence that high doses are directly harmful (1).

However, high doses of biotin can interfere with lab tests by falsely skewing thyroid hormone levels, vitamin D levels, or other results, which could have a significant impact on your medical care (1, 13).

Be sure to let a healthcare professional know if you’re taking a biotin supplement prior to having lab work done.

Are there side effects of taking biotin?

Biotin doesn’t appear to be linked to any notable side effects. Some people report skin rashes or digestive upset after taking a biotin supplement, but there’s currently no research on specific biotin side effects.

Remember, however, that biotin may interfere with lab testing results. Biotin supplements may also interfere with anticonvulsant medications, so make sure to speak with a healthcare professional before taking biotin if you’re on an anticonvulsant (1).

How to tell if you need more biotin?

Biotin deficiency is rare, but if you’re deficient in biotin you may experience (1):

• hair thinning or hair loss
• red, scaly skin rash
• conjunctivitis, or pink eye
• brittle nails
• fatigue
• seizures

If you suspect biotin deficiency, speak with a healthcare professional about confirming it with a blood test.

What happens if you take too much biotin supplement?

Taking too much biotin from supplements may cause falsely high or low thyroid hormone or vitamin D levels. For this reason, it’s important to notify your healthcare professional prior to having bloodwork done if you’re taking biotin or a hair, skin, and nails supplement (1, 13).

How long does a biotin supplement stay in your system?

According to one study, blood biotin level reaches its peak 2–4 hours after taking a biotin supplement. But the study noted that your biotin may still be elevated above normal even at 24 hours after taking a supplement (14).

For this reason, your healthcare professional may ask you to stop taking biotin supplements for 48 hours prior to having bloodwork done (14).

Top 10 Best Vitamins Biotin for Hair

Brittle nails, thinning hair and dull skin are not only beauty problems. The problem goes deep under the skin. These external manifestations are an indicator of specific underlying problems, which are mainly associated with a certain type of vitamin deficiency. Biotin is touted as a panacea for all such problems.

Biotin is a water soluble vitamin that plays a vital role in the health of your hair, skin and nails. Although its deficiency is rare, if you don’t get enough biotin, you may experience hair loss or dull skin problems. The only way out of this is to use supplements. Biotin research is rare and still in its early stages.

In order to help you find the very best supplement, we’ve researched & narrowed down our list to the 10 best biotin vitamins for hair. But before you explore your options, you need to know what biotin is and what it does for your body.

What is biotin?

Biotin is a B vitamin that is vital for facilitating a healthy metabolism and making essential enzymes. Biotin converts certain nutrients into energy and is believed to improve your body’s keratin infrastructure. Like any other B vitamin, biotin helps the body absorb proteins and process glucose. It is also known as vitamin B7 or vitamin H.

Since the human body cannot synthesize biotin, we must consume it through our diet or supplements. The body does not store any reserves of biotin, and unused biotin is excreted from the body in the urine. Therefore, it must enter our system daily through our diet. Biotin is a coenzyme that enhances the action of the enzyme.

What causes biotin deficiency?

Biotin deficiency is rare. This can be caused by one of two factors – a genetic mutation or an excess consumption of raw egg white. Egg white contains a compound that significantly inhibits the absorption of biotin, which is deactivated when the egg is boiled.

Biotin is an essential nutrient found naturally in small amounts in some foods and can also be taken as a dietary supplement. Since this vitamin is water soluble, it is not stored in the body. Hence, you need to consume it through food and supplements.

Unfortunately, there is no good laboratory test for biotin deficiency. Low biotin levels are reflected in symptoms such as thinning hair, brittle nails, and dull skin. Although deficiency is rare, it can occur in chronic smokers, alcoholics, and pregnant women. Your diet can also cause it. People who consume a lot of processed food are more likely to have a deficiency.

Benefits of eating biotin

Mammals cannot synthesize biotin. Therefore, we must depend on a diet of microbial and plant sources. Biotin works as a coenzyme in humans. It helps the body process glucose and metabolize proteins, fats, and carbohydrates. It is believed to be good for healthy hair, nails and skin.

This vitamin is present in many medical and cosmetic products, although biotin cannot be absorbed through the skin or hair.

The European Food Safety Authority (EFSA), which provides scientific advice to assist policy makers, has confirmed the many benefits of dietary biotin intake:

• Essential for carbohydrate and fat metabolism
• Promotes energy metabolism
• Helps maintain healthy skin and mucous membranes
• Contributes to the normal functioning of the nervous system
• Helps maintain healthy hair
• Helps normal psychological functions

Biotin supplements are growing in popularity and are readily available from pharmacies. Here are the top 10 biotin supplements you can consider.

How to choose biotin vitamins for hair?

Buying an add-on should always be a well thought out decision. Here is a list of several factors that you need to keep in mind when purchasing a biotin supplement.

• Ingredients: is a sign of a conscious shopper to look at ingredients when making a purchase, especially when it comes to health related products. If you are a vegetarian, make sure the supplement does not contain animal-based gelatin. It’s always best to go for non-GMO verified foods and those that don’t contain any common allergens.
• Side Effects: Taking a biotin supplement can lower your B5 levels and this can lead to rashes, acne and itching. Although this does not happen to everyone who takes biotin supplements, in case you experience this problem, talk to your doctor and start taking Biotin with Vitamin B5 together to balance the intake. Also, if you are planning to have blood tests, you may need to stop your supplements a day or two before. This is because the biotin supplement messes with your blood test results.
• Quantity: It’s very important to make sure you choose a supplement that has enough biotin for your needs.

What are the benefits of taking biotin?

Here is a list of several possible benefits of biotin:

• May regulate blood sugar levels.
• Helps in energy production.
• Biotin is effective in treating brittle nails.
• Biotin is believed to promote healthy hair growth, although there is little evidence to support this claim.
• Important during pregnancy and lactation.
• Improves your skin health. Biotin deficiency can lead to various skin problems.

What should I know before taking biotin?

Most biotin supplements are available in megadoses, which are usually more than the accepted amount your body needs per day. Since it is a water-soluble vitamin, anything that is not absorbed or required by your body will be flushed out in the urine. Biotin supplements may interfere with the results of laboratory tests that examine the blood.
If you are considering taking a biotin supplement, it is always recommended that you consult with your physician prior to doing so to determine the appropriate dosage and supplement you should choose to ensure that there are no potential future health risks.

How to take biotin?

Current nutritional guidelines advise you not to exceed 10,000 micrograms of supplemental biotin per day. Several medical studies have reported the use of 40,000 micrograms of biotin supplements to treat a deficiency, which do not show any side effects, but if we are talking about nutritional recommendations, 10,000 micrograms or 10 mg is the upper limit.

How much biotin do I need to take for hair growth?

The Food and Drug Administration does not have a recommended daily allowance for biotin. Health experts recommend that if a child is over 10 years old, they should get somewhere between 30 to 35 micrograms of biotin per day. If you intend to drink biotin, there is no harm in increasing the dose to 1000-5000 micrograms. Check with your doctor who will prescribe the correct supplement and dosage for you.

Biotin supplements can help improve the health of your skin, hair, and nails. If you are considering taking biotin supplements, be sure to let your doctor know to make sure there are no potential health concerns.

How to choose a biotin supplement

Here are some things to consider when purchasing a biotin supplement:

• Third party tested. It’s best to choose a supplement that has been third-party tested to ensure quality and purity. Many of the supplements on this list are third-party tested, while the rest are made in CGMP-certified facilities with their own test protocols.
• Allergies and dietary needs. Also consider any allergies or dietary considerations you may have. Klaire Labs and Pure Encapsulations offer hypoallergenic biotin supplements, while Garden of Life offers organic, vegan options.
• Add-on type. As with any supplement, you need to choose the form – softgel, gum, or liquid – that is easiest and most convenient for you to take.
• Your goals. If you don’t need a biotin supplement but want to improve the quality of your hair, skin and nails, choose a supplement specifically designed for that purpose. It will likely contain additional ingredients that support your goals.

Be aware that there is little evidence to support the use of biotin for hair, nail, or skin health. A healthy, balanced diet will benefit your hair, skin, and nails far more than taking supplements.

Biotin supplements can also interfere with some laboratory tests, such as those used to measure thyroid hormones or heart damage, which can lead to false results. This can lead to misdiagnosis of serious diseases that can be dangerous and even fatal (1, 3).

As a result, it is important to talk to your doctor before taking a biotin supplement.

Finally, since all of the supplements below are high in biotin, it is important not to take more than the manufacturer’s recommended dose.

Frequently Asked Questions

Why are biotin supplements good?

Biotin supplements are most commonly used to promote healthy hair or nail growth. Some symptoms of biotin deficiency are hair loss, skin changes, and brittle nails.1).

However, there is limited evidence to support this particular use of biotin because most people are not deficient in biotin despite its popularity as a hair, skin and nail vitamin.12).

However, some populations are at risk of biotin deficiency and may benefit from supplementation, including those with alcohol use disorders, pregnant or breastfeeding women, and biotinidase deficiency, which affects the metabolism of biotin in the body. 1).

How much biotin should I take per day?

The Daily Adequate Intake (AI) levels of biotin for adults are as follows (1): Pregnancy: 30 mcg

AI levels for biotin are believed to meet the needs of at least 50% of the population until more research is done into biotin requirements.

Most biotin supplements contain significantly more than AI. The supplements on this list provide 830-33,333% of the Daily Value of biotin. Fortunately, there is no evidence that high doses cause direct harm (1).

However, high doses of biotin can interfere with lab tests by misrepresenting thyroid hormone levels, vitamin D levels, or other results, which can have a significant impact on your health care (1, 13).

Be sure to tell your health care provider if you are taking a biotin supplement before doing any lab tests.

Are there side effects from taking biotin?

Biotin does not appear to be associated with any notable side effects. Some people report skin rashes or indigestion after taking a biotin supplement, but there are currently no studies on specific side effects of biotin.

Be aware, however, that biotin may interfere with lab results. Biotin supplements can also interfere with anti-seizure medications, so be sure to talk to your doctor before taking biotin if you are taking anti-seizure medications (1).

How do you know if you need more biotin?

Biotin deficiency is rare, but if you are deficient in biotin you may experience (1):

• thinning or hair loss
• red, scaly skin rash
• conjunctivitis or pink eye
• scrap bone nails
• fatigue
• seizures

If you suspect a biotin deficiency, talk to your doctor about confirming this with a blood test.

What happens if you take too much of a biotin supplement?

Taking too much biotin from supplements can lead to falsely high or low levels of thyroid hormones or vitamin D. For this reason, it is important to tell your healthcare provider before having a blood test if you are taking biotin or a hair, skin, and nail supplement ( 1, 13).

How long does a biotin supplement stay in your body?

According to one study, blood levels of biotin reach their peak 2-4 hours after taking a biotin supplement. But research has noted that your biotin levels can be elevated above normal even 24 hours after taking a supplement.14).

For this reason, your healthcare provider may ask you to stop taking biotin supplements 48 hours before donating blood (14).
