What are the side effects of B12 sublingual tablets? What are the uses and dosage of this vitamin supplement? Get comprehensive information on the safety and precautions of taking B12 sublingual tablets.

The Versatility of Cyanocobalamin (B12) Sublingual Tablets

Cyanocobalamin (B12) sublingual tablets are a popular form of vitamin B12 supplement that offers a convenient and effective way to address vitamin deficiencies. These tablets are designed to be placed under the tongue, where the B12 is absorbed directly into the bloodstream, bypassing the digestive system. This makes them a particularly useful option for individuals who have difficulty absorbing B12 through oral supplementation or who require higher doses of the vitamin.

Understanding the Uses and Benefits of B12 Sublingual Tablets

Vitamin B12, also known as cobalamin, plays a crucial role in the body’s overall health and well-being. It is essential for the proper functioning of the nervous system, the production of red blood cells, and the maintenance of healthy DNA. B12 sublingual tablets are commonly used to treat or prevent vitamin B12 deficiency, which can occur due to factors such as poor diet, certain medical conditions, or the use of certain medications.

Some of the primary uses and benefits of B12 sublingual tablets include:

  • Addressing vitamin B12 deficiency, including pernicious anemia
  • Supporting the production of red blood cells and preventing anemia
  • Maintaining a healthy nervous system and cognitive function
  • Promoting energy production and reducing fatigue
  • Supporting the health of the skin, hair, and nails

Exploring the Potential Side Effects of B12 Sublingual Tablets

While B12 sublingual tablets are generally well-tolerated, there are some potential side effects that users should be aware of. The most common side effects include mild stomach upset, flushing, and diarrhea. These effects are usually temporary and may subside as the body adjusts to the supplement.

In rare cases, more serious side effects may occur, such as an allergic reaction. Symptoms of a severe allergic reaction may include rash, itching, swelling (especially of the face, tongue, or throat), and difficulty breathing. If these symptoms occur, it is essential to seek immediate medical attention.

Dosage and Precautions for B12 Sublingual Tablets

The recommended dosage for B12 sublingual tablets can vary depending on the individual’s needs and the specific brand or formulation. It is essential to carefully follow the instructions on the product label or consult with a healthcare professional to determine the appropriate dosage.

Before taking B12 sublingual tablets, it is important to inform your healthcare provider of any underlying medical conditions, such as diabetes, liver problems, or pernicious anemia, as these may affect the safety and efficacy of the supplement. Additionally, individuals with phenylketonuria (PKU) or other conditions that require a restricted intake of aspartame or phenylalanine should consult with their healthcare provider before using B12 sublingual tablets, as some formulations may contain these ingredients.

Ensuring Proper Use and Storage of B12 Sublingual Tablets

To get the most benefit from B12 sublingual tablets, it is important to follow the instructions on the product label carefully. This includes taking the tablets as directed, typically once daily, and holding them under the tongue until they fully dissolve. Swallowing the tablets whole without chewing or crushing them is also important, as this can affect the absorption and release of the B12.

Additionally, it is essential to store B12 sublingual tablets properly, typically in a cool, dry place away from direct light and heat. Exposure to these environmental factors can potentially reduce the potency and effectiveness of the supplement.

Consulting with a Healthcare Professional for Personalized Guidance

While B12 sublingual tablets are generally safe and well-tolerated, it is always a good idea to consult with a healthcare professional before starting any new supplement regimen. They can provide personalized guidance on the appropriate dosage, potential interactions with other medications or medical conditions, and help ensure that the supplement is being used safely and effectively.

By understanding the uses, benefits, and potential side effects of B12 sublingual tablets, individuals can make informed decisions about incorporating this supplement into their overall health and wellness routine. With proper use and guidance from a healthcare provider, B12 sublingual tablets can be a valuable tool in addressing vitamin deficiencies and supporting overall health and well-being.

What Causes B12 Side Effects?

Are you having B12 side effects, like heart palpitations or digestive issue after taking B12 or B vitamins?  In this article, we look at these side effects and what typically causes them.   We also look at what some of the common side effects are and how common they occur. 

 

If you want to know what cause B12 side effects, keep reading. 

B12 Side Effects

B12 side effects are not very common.  However, they do occur in a segment of the population.  Most of the time these “side effects” are not a true B12 side effect.  Think about it.  B12 is an essential part of our natural biochemistry.  To have a side effect to that is contradictory to how your biochemistry naturally works.  That doesn’t mean you can’t be sensitive to something in the B12 or B complex that you took or even B12 itself.  Because B12 is an essential part of how your biochemistry works, it’s not very common that it is actually B12 causing the side effects or reactions.   More common it is something that’s in with the B12 that you took.  Before we get into the common reasons for these side effects or triggers from B12, let’s look at the.  Let’s look at what some of these side effect reactions etc that people have from taking B12. 

 

Causes of Digestive B12 Side Effects

Nausea, bloating, upset stomach, and various digestive symptoms are one of the more commonly reported side effects from taking B12.  In these cases, they are often taking a B complex that they swallow.  This contains B12 but also has the other B vitamins other than B12.  All B vitamins feed bacteria.  If you get digestive symptoms after taking B12, often there is a bacterial overgrowth or possibly fungal overgrowth creating the digestive symptoms. Anytime patients tell me they have a reaction from taking B vitamins, like nausea or some kind of digestive symptom, I automatically think that they might have some microbial issue.  It’s not always the case but it does come to mind.   If that happens to be your issue, taking your B vitamins or B12 in the form of injection, might resolve the issue.  We wouldn’t expect the injection to do this because it bypasses the overgrowth. 

 

Causes of Anxiety B12 Side Effects

Another common side effect or issue reported from taking B12 or B vitamins is anxiety, heart palpitations and difficulty sleeping.  B12 definitely can do this but it is more common for other B vitamins to do this.  If you get a B12 injection and it stings, that means it’s not just B12.  B12 does not sting but the other B vitamins do.  You want to differentiate which one of them is causing the issue. You could just get B12 alone and see how you react to that.  If you are getting these palpitations from just B12, then you know it from the B12 only. 

If you know for sure that you only take B12, swallowing or injection, and you get anxiety or heart palpitations, consider taking a much smaller dose.  Take the smallest amount that you think would not create a reaction.   Start with that and gradually work up to higher doses.  Once you find the dose that is not creating these problems, over time your body may adjust to it and you won’t have such a strong reaction.  Sometimes palpitations and anxiety occur when there is a big deficient.  As result, your body will get very stimulated from the B12.  Sometimes the same bacterial issue that causes digestive issues from swallowing the B12 can also cause these heart palpitations, anxiety etc.  The same issue wouldn’t be expected though when you take an injection.  If you have both the digestive issues and the anxiety and palpitations when you swallow it, we wouldn’t expect the same thing when you take an injection. 

 

Other Cause of B12 Side Effects

Another thing to consider is what’s in the B vitamins too.  Sometimes people think they are just taking a plain B 12 or B complex and there are other things in there,  like probiotics or prebiotics and other herbs.  These can cause reactions too.   Make sure you check all the ingredients to ensure you are not sensitive to one of those things.  Also when you take B12 as a sublingual tablet or chewable form, it will usually contain sugar alcohols like xylitol etc.  That gives it sweet taste but those can can definitely cause digestive issue for some people. 

If switching the route of administration and dosage don’t help, you may also have like a substrate issue.   B12 is used to recycle homocysteine.  Homocysteine comes from amino acid cysteine and methionine.  If your levels of cysteine and methionine are low, the B12 has nothing to do once you intake it.  That’s called methyl trapping.  You can check your fasting homocysteine to see if your homocysteine levels are low.  This may indicate  a bigger problem going on (inflammation) or just simply a protein deficiency.  However people with low homocysteine, mostly don’t have these negative reactions to taking B12 as an injection or oral.  Still it could be part of the problem in your situation.  

In terms of the injections, the type of injection you’re getting actually does matter.  If you’re getting a cyanocobalamin (also present in oral and sublingual B12) that’s more likely to cause negative reactions.  The cobalamin molecule is bound to different functional groups.  If your functional group is cyanide that’s called cyanocobalamin.  While it is a very small amount of cyanide that you’re getting, you are getting cyanide.  Cyanide is poisonous to our mitochondria and cells and tissues.  You really don’t want to be taking that one.  Not everyone will have a reaction or a negative reaction to it.  In fact, most people don’t.  Still, if that’s what you’re getting, then I would suspect that as potentially the problem.  You can easily get another form called hydroxy and in some cases you can get the methylcobalamin.  The methylcobalamin does have to be compounded but it is available in most areas. 

That should give you a better understanding of what causes B12 side effects.   If you have questions about the content in this article, please ask it in the comment section below.

Vitamin B12 health benefits and supplement instructions

There can be many reasons why people start taking vitamin B12, including various diseases, or an examination and tests were carried out, during which a person was found to be deficient in this vitamin.

Or those who do not consume animal products, ie meat, fish, eggs, milk, often need vitamin B12.

If you decide to supplement with B12 or your doctor has prescribed it, then vitamin-mineral complexes in this case will not work.

For example, Optimum Nutrition Opti-men contains B12 in the form of cyanocobalamin, 100 mcg, 4000% DV. This vitamin and mineral complex will not suit you. Firstly, the dosage should be higher, from 1000 mcg, and, secondly, you should remember about the compatibility of vitamins – B12 is needed in its pure form (methylcobalamin).

Also in the composition of such a supplement may be folic acid, which is perfectly combined with methylcobalamin, without interfering with each other’s absorption.

If you are taking B-complex vitamins such as SOLGAR B-Complex 100, Puritan’s Pride B-Complex and B-12, Doctor’s Best Fully B Complex, then you don’t have to stop them, just take a break between doses. For example, during breakfast, a vitamin-mineral complex, and after 4-5 hours, vitamin B12.

B12 tablets are available as cyanocobalamin and methylcobalamin. This is very easy to check, the manufacturer, as a rule, always indicate this on the back of the package in the composition table.

What is the difference between cyanocobalamin and methylcobalamin?

The latter is the active form of B12 and has a higher bioavailability. However, it is worth noting that the cost may be slightly higher. Although cyanocobalamin is cheaper, its bioavailability is lower, so it is preferable to buy vitamin B12 methylcobalamin.

What is the best way to take vitamin B12?

There is a wide selection of B12 on the market in various forms of release: spray, chewable tablets, liquid, lozenges, regular tablets, capsules. At the same time, it is worth saying that B12 in the form of a spray, chewable tablets and lozenges will be absorbed best.

Which brand is better (B12)?

Now the market is oversaturated with hundreds of manufacturers of vitamins and other supplements. We recommend trusting only trusted brands that have been around for many years and have a good reputation. For example: SWANSON, SOLGAR, NOW FOODS and many others, which are also presented in our store.

How to take vitamin B12?

There is no definite course for taking B12, it is taken based on the need. Vegetarians or those who, for some reason, do not consume enough animal protein, can follow the course on an ongoing basis, because B12 is not toxic, it is a water-soluble vitamin and is quickly excreted from the body. Therefore, it is extremely difficult to achieve an overdose.

Single dosage should be between 1000-1500 µg. It is advisable to take in the morning after a low-fat meal. It is also worth remembering that taking B12 cannot be combined with taking supplements (the exception is folic acid), especially Omega-3 and other fatty acids.

Solgar’s products have been recognized many times with prestigious international labels. Specialists use modern equipment to develop unique recipes for vitamin complexes to improve health.

Composition

The dietary supplement contains only one component – vitamin B 12. This is an important element with beneficial properties for the body:

  • stabilizes the nervous system;
  • supports the work of the heart;
  • helps regenerate red blood cells;
  • improves energy metabolism;
  • ensures the growth and development of the fetus during pregnancy;
  • preserves the health of nails, hair, skin;
  • increases the absorption of folic acid (vitamin B9).

Additional ingredients in small amounts serve to form a tablet, improve dissolution and absorption, and flavor.

The unique structure in this formulation, methylcobalamin, is the active coenzyme form of vitamin B12. In the digestive system, for assimilation, the vitamin must be converted into this particular form. In a supplement from Solgar, it is produced ready for absorption in the intestines.

Taking a vitamin in this form, you can be sure that it will be fully absorbed! This is especially important for people with digestive disorders, diseases of the digestive system. They do not have all the nutrients well absorbed. Vitamin B12 in the form of methylcobalamin is sure to be recycled and beneficial.

Indications for use

Vitamin B12 should be taken when it is deficient. To do this, you need to consult a doctor, take tests for the content of this vitamin.

General indications for taking vitamin B12:

  • anemia of various origins;
  • trigeminal neuralgia;
  • sciatica;
  • migraine;
  • polyneuritis;
  • sclerosis;
  • liver disease;
  • skin pathologies;
  • radiation sickness.

It is useful to take B12 for vegetarians. This element is found in meat, dairy products, which adherents of such nutrition do not consume. Solgar’s dietary supplement is made from herbal ingredients and is suitable for vegetarians.

Instruction

The preparation contains vitamins in the form of lozenges. They are small, pink in color, have a pleasant cherry aroma and taste.

The manufacturer insists on taking his drug sublingually. This means that the tablet should be placed under the tongue. The instructions say that leftovers can be swallowed after 30 seconds. The tablets dissolve quickly and are pleasant to drink. This method avoids getting the drug into the digestive system.

Vitamins immediately penetrate into the circulatory system. This use is useful for people with diseases of the stomach and intestines. In these cases, the absorption of nutrients is difficult, it is not guaranteed that the body will receive vitamin B12. With the sublingual use of the supplement, the useful element achieves its goal.

It is recommended to take one tablet daily with food. Your doctor may recommend a different vitamin B12 regimen. There are 60 pieces in a jar, which is enough for a course of treatment, about 2 months. The duration of the reception can also be adjusted by a personal doctor.

Storage

Bioadditive does not require special storage conditions. Opened packaging should be stored in a dry, cool place. Keep the drug out of the reach of children, as the lid does not have additional protection.

This supplement is intended for the adult consumer.

Drug interaction

Vitamin B12 is difficult to digest. For it to be properly digested, certain bacteria must be present in the intestines. For this reason, Solgar specialists use a special formula that facilitates the entry of a useful element into the circulatory system.

For good digestion of vitamin B12 certain conditions are needed. Eating large amounts of citrus fruits reduces the absorption of this vitamin. Poorly affects the level of vitamin B12 potassium, chloramphenicol (antibiotic).

Together with vitamin B12 it is good to take B6, they mutually facilitate the assimilation of each other. Calcium ions help cyanocobalamin to penetrate into the circulatory system. For this reason, you need to eat dairy products, cottage cheese, cheese and sardines.

For good digestion of vitamin B12, pancreatic enzymes are needed. With diseases of this internal organ, the vitamin will not be able to be fully absorbed even if other conditions are met.
