Statins and niacin. Niacin for Cholesterol Management: Benefits, Risks, and Usage Guide
How does niacin affect cholesterol levels. What are the potential benefits and risks of using niacin for cholesterol management. How should niacin be taken properly for optimal results. What are the important considerations before starting niacin therapy.
Understanding Niacin’s Role in Cholesterol Management
Niacin, also known as vitamin B3 or nicotinic acid, has long been recognized for its potential to improve cholesterol levels. However, recent research has shed new light on its efficacy and safety profile, prompting a reevaluation of its role in cardiovascular health management.
Niacin works by influencing the body’s lipid metabolism, potentially leading to improvements in various cholesterol markers. Its effects include:
- Lowering LDL (bad) cholesterol
- Raising HDL (good) cholesterol
- Reducing triglyceride levels
Despite these potential benefits, the use of niacin for cholesterol management has become less common in recent years. Why has this shift occurred? The answer lies in the evolving understanding of its risk-benefit profile and the availability of more effective alternatives.
The Changing Landscape of Niacin Use in Cardiovascular Health
Recent studies have cast doubt on the additional benefits of niacin when used in combination with statins, the primary medication for managing high cholesterol. Research suggests that adding niacin to statin therapy may not significantly reduce the risk of cardiovascular events such as heart attacks and strokes beyond what statins alone can achieve.
This revelation, coupled with the potential for unpleasant and sometimes dangerous side effects, has led to a decline in niacin prescriptions. However, it’s important to note that niacin may still have a role in certain situations, particularly for individuals with very high cholesterol levels or those who cannot tolerate other cholesterol-lowering medications.
When Might Niacin Still Be Prescribed?
- For patients with extremely high cholesterol levels that don’t respond adequately to statins alone
- In cases where individuals cannot tolerate statins or other primary cholesterol-lowering medications
- As part of a combination therapy approach in specific clinical scenarios
Types of Niacin Medications and Their Proper Use
Niacin is available in various forms and formulations, each with its own characteristics and considerations. It’s crucial to understand the differences between prescription niacin and over-the-counter (OTC) supplements.
Prescription Niacin Options
Prescription niacin medications come in different brands and generic forms. These are specifically formulated and dosed for cholesterol management under medical supervision. Some key points about prescription niacin include:
- Available in various dosages to meet individual needs
- May be prescribed alone or in combination with other cholesterol-lowering drugs
- Formulated to minimize side effects while maximizing therapeutic benefits
Over-the-Counter Niacin Supplements
It’s important to distinguish between prescription niacin and OTC niacin supplements. Using OTC niacin for cholesterol management without medical supervision can be dangerous. Why is this the case?
- OTC supplements may not be regulated as strictly as prescription medications
- Dosages may vary and may not be appropriate for cholesterol management
- The risk of side effects may be higher without proper medical oversight
Always consult with a healthcare provider before considering niacin for cholesterol management, and never substitute OTC supplements for prescribed medication.
Proper Administration of Niacin for Optimal Results
Taking niacin correctly is crucial for maximizing its benefits and minimizing potential side effects. How should niacin be taken to ensure the best outcomes?
General Guidelines for Niacin Administration
- Follow your healthcare provider’s instructions precisely
- Take niacin 1 to 3 times daily, depending on the prescribed dosage
- Do not break or chew extended-release tablets
- Some formulations should be taken at bedtime with a light, low-fat snack
- Others may be prescribed to be taken with dinner
- Avoid alcohol and hot drinks while taking niacin to reduce flushing
- Store medication in a cool, dry place, out of reach of children
Is timing important when taking niacin? Yes, adhering to the prescribed schedule is crucial for maintaining consistent blood levels and managing side effects. Some formulations are designed for nighttime administration to minimize flushing during waking hours.
Lifestyle Considerations While Taking Niacin
Niacin therapy should be part of a comprehensive approach to heart health. What other measures can complement niacin treatment?
- Follow a heart-healthy diet low in saturated and trans fats
- Engage in regular physical activity as recommended by your healthcare provider
- Manage stress through relaxation techniques or counseling
- Quit smoking and limit alcohol consumption
- Maintain a healthy weight
Essential Precautions and Risk Assessment Before Starting Niacin
Before initiating niacin therapy, it’s crucial to undergo a thorough risk assessment. What factors should be considered to ensure safe and effective treatment?
Medical History and Current Health Status
Inform your healthcare provider about:
- Pregnancy or breastfeeding plans
- Any known allergies
- All current medications, including over-the-counter drugs and supplements
- Alcohol consumption habits
- Existing medical conditions, particularly diabetes, kidney disease, peptic ulcers, or gout
Potential Drug Interactions
Niacin can interact with various medications, potentially altering their effectiveness or increasing the risk of side effects. Common interactions include:
- Other cholesterol-lowering medications
- Blood thinners
- Diabetes medications
- Blood pressure medications
Always provide your healthcare provider with a complete list of all medications and supplements you’re taking to avoid potentially harmful interactions.
Monitoring and Managing Niacin Therapy
Regular monitoring is essential for ensuring the safety and efficacy of niacin treatment. What aspects of your health will be monitored during therapy?
Routine Blood Tests
Your healthcare provider will likely order periodic blood tests to:
- Assess the effectiveness of niacin in improving cholesterol levels
- Monitor liver function to detect any potential liver-related side effects
- Check blood glucose levels, particularly in individuals with or at risk for diabetes
- Evaluate other relevant markers of cardiovascular health
Side Effect Management
Understanding and managing potential side effects is crucial for successful niacin therapy. What are the most common side effects, and how can they be managed?
Flushing
Flushing is the most common side effect of niacin, characterized by redness, warmth, and tingling of the skin, particularly on the face and upper body. To minimize flushing:
- Take niacin with meals or a low-fat snack
- Avoid hot beverages or alcohol around the time of niacin intake
- Consider taking an aspirin 30 minutes before niacin (if approved by your doctor)
- Start with a low dose and gradually increase as directed by your healthcare provider
Gastrointestinal Effects
Some individuals may experience stomach upset, diarrhea, or nausea. These effects can often be mitigated by:
- Taking niacin with food
- Using extended-release formulations
- Gradually increasing the dose over time
Recognizing and Responding to Serious Side Effects
While most side effects of niacin are mild and manageable, it’s crucial to be aware of potentially serious complications. When should you seek immediate medical attention?
Signs of Liver Problems
- Yellowing of the skin or eyes (jaundice)
- Dark urine
- Persistent nausea or vomiting
- Upper right abdominal pain
Muscle-Related Issues
- Unexplained muscle pain, tenderness, or weakness
- Fever or flu-like symptoms accompanying muscle symptoms
Cardiovascular Concerns
- Irregular heartbeat or significant changes in heart rhythm
- Sudden changes in blood pressure, particularly severe drops
Other Serious Side Effects
- Severe skin reactions or rashes
- Sudden vision changes or loss
- Signs of gout, such as severe joint pain or swelling
If you experience any of these symptoms, discontinue niacin use and seek immediate medical attention. Prompt recognition and response to serious side effects can prevent potentially life-threatening complications.
The Future of Niacin in Cholesterol Management
As medical research continues to evolve, the role of niacin in cholesterol management may continue to change. What does the future hold for niacin therapy?
Ongoing Research and Clinical Trials
Scientists are continuing to investigate the potential benefits and risks of niacin in various populations and clinical scenarios. Some areas of ongoing research include:
- The efficacy of niacin in specific subgroups of patients with cardiovascular risk factors
- Novel formulations of niacin designed to minimize side effects while maintaining efficacy
- The potential role of niacin in combination with newer cholesterol-lowering therapies
Personalized Medicine Approaches
As our understanding of genetic factors influencing drug response improves, there may be opportunities to identify individuals who are most likely to benefit from niacin therapy. This personalized approach could help optimize treatment outcomes while minimizing risks.
Alternative Therapies and Emerging Treatments
While niacin’s role may be changing, research into new cholesterol-lowering therapies continues. Some promising areas include:
- PCSK9 inhibitors, a new class of injectable medications that can dramatically lower LDL cholesterol
- Bempedoic acid, an oral medication that offers an alternative for statin-intolerant patients
- RNA interference therapies that target specific genes involved in cholesterol metabolism
As these new treatments emerge, the landscape of cholesterol management continues to evolve, potentially offering more effective and personalized options for patients with cardiovascular risk factors.
In conclusion, while niacin’s role in cholesterol management has changed in recent years, it remains an important option for certain patients. Understanding its benefits, risks, and proper use is crucial for those considering or currently undergoing niacin therapy. As with any medical treatment, close collaboration with healthcare providers and ongoing monitoring are essential for achieving optimal outcomes in cardiovascular health management.

How Niacin Helps
Improving your cholesterol levels can help protect you from:
- Heart disease
- Heart attack
- Stroke
Your health care provider will work with you to lower your cholesterol by improving your diet. If this is not successful, medicines to lower cholesterol may be the next step. Statins are thought to be the best drugs to use for people who need medicines to lower their cholesterol.
Research now suggests that niacin does not add to the benefit of a statin alone for reducing the risk of cardiovascular events, including heart attacks and stroke.
In addition, niacin can cause unpleasant and potentially dangerous side effects. Therefore, its use has been declining. However, some people may be prescribed niacin in addition to other drugs if they have very high cholesterol or if they do not tolerate other medicines.
Which Niacin Medicine is Right for you?
There are different brands of niacin medicines. Most of these also come in a less expensive, generic form.
Niacin may be prescribed along with other medicines, such as a statin, to help lower cholesterol. Combination tablets that include nicotinic acid plus other medicines are also available.
Niacin is also sold over-the-counter (OTC) as a supplement. You should not take OTC niacin to help lower cholesterol. Doing so could have serious side effects.
How to Take Niacin
Take your medicine as directed. The medicine comes in tablet form. Do not break or chew tablets before taking the medicine. Do not stop taking your medicine without talking with your provider first.
You take niacin 1 to 3 times per day. It comes in different doses, depending on how much you need.
Read the label on the pill bottle carefully. Some brands should be taken at bedtime with a light, low-fat snack; others you will take with dinner. Avoid alcohol and hot drinks while taking niacin to reduce flushing.
Store all of your medicines in a cool, dry place. Keep them where children cannot get to them.
You should follow a healthy diet while taking niacin. This includes eating less fat in your diet. Other ways you can help your heart include:
- Getting regular exercise
- Managing stress
- Quitting smoking
Know Your Risks
Before you start taking niacin, tell your provider if you:
- Are pregnant, plan to become pregnant, or are breastfeeding
- Have allergies
- Are taking other medicines
- Drink a lot of alcohol
- Have diabetes, kidney disease, peptic ulcer, or gout
Talk to your provider about all of your medicines, herbs, or supplements. Certain medicines may interact with niacin.
Regular blood tests will help you and your provider:
- See how well the medicine is working
- Monitor for side effects, such as liver problems
Possible Side Effects
Mild side effects may include:
- Flushing and red face or neck
- Diarrhea
- Headache
- Upset stomach
- Skin rash
Though rare, more serious side effects are possible. Your provider will monitor you for signs. Talk with your provider about these possible risks:
- Liver damage and changes to liver enzymes
- Severe muscle pain, tenderness, and weakness
- Heartbeat and rhythm changes
- Changes in blood pressure
- Severe flushing, skin rash, and skin changes
- Glucose intolerance
- Gout
- Vision loss or changes
When to Call the Doctor
You should call your provider if you notice:
- Side effects that are bothering you
- Fainting
- Dizziness
- Fast or irregular heartbeat
- Yellow skin or eyes (jaundice)
- Muscle pain and weakness
- Other new symptoms

Statin and niacin treatment reduces risk of heart attack by 70 percent, can reverse arterial buildup
Archive
November 13, 2000
NEW ORLEANS (Nov. 13) — Treatment with a combination of statin and niacin can slash the risk of hospitalization for chest pain or a heart attack by 70 percent among patients who are likely to suffer heart attacks and/or death from cardiovascular problems, according to a study presented here by researchers at the University of Washington School of Medicine.
The treatment combines two already well-known ways of improving cardiac health: the use of a statin drug to lower levels of the “bad” cholesterol, LDL, and the use of niacin to boost levels of the “good” cholesterol, HDL.
The study found that use of this combined treatment, in people with low levels of good cholesterol and average levels of bad cholesterol, could even remove plaque buildup in the arteries. Cardiovascular disease is the No. 1 killer in the Western Hemisphere.
At the start of the study and again after three years of treatment, doctors performed angiograms of the patients’ arteries. The angiograms showed that in most of the patients who received the combination treatment, plaque buildup had actually decreased.
“This is the first demonstration of a striking clinical benefit from combination drug therapy for a common type of coronary disease patient,” said Dr. B. Greg Brown, a cardiologist and UW professor of medicine.
Researchers are finishing up their analysis of the study data, and plan to submit their report this winter for publication. Brown is the study’s lead author. The results were presented in New Orleans on Nov. 13 at the Scientific Sessions of the American Heart Association.
“This interesting study is a good demonstration of the enormous value of cholesterol management in patients with coronary disease,” said Dr. Claude Lenfant, director of the National Heart, Lung, and Blood Institute, which funded the study.
The same study found that a mixture of antioxidant vitamins had no effect on cardiovascular outcomes. Scientists are not sure why this is so, since there has been laboratory evidence that suggests antioxidants should be helpful.
“More research and larger studies are needed to confirm the lack of effectiveness of antioxidant vitamins on risk for coronary events,” Lenfant said.
Brown was involved in the first studies in the late 1980s that showed that a kind of statin, lovastatin, could reduce the occurrence of major cardiovascular events by about 25 to 35 percent. Giving statins to people with cardiovascular disease is now common.
“What you expect with statins is a slowing of the disease progression, but not a stopping. Arteries continue to get narrower, but not as fast,” Brown said. “But when niacin is combined with a statin, the artery blocking actually improves, on average.”
Brown and colleagues surmised that combining simvastatin with niacin might prevent even more heart attacks and such cardiac events. The goal would be to reduce plaque buildup. That’s important because the cholesterol-rich plaque is what can clog artery walls and lead to fatal complications.
Cholesterol: The statin lowers blood levels of LDL, which is called the “bad” cholesterol because it is more likely to clog ateries. Niacin, or Vitamin B3, is the best agent known to raise blood levels of HDL, which helps dissolve cholesterol deposits from the artery walls.
The 160 patients involved in the study had low levels of good HDL cholesterol (a level of 35 or less). At least four out of every 10 people with coronary artery disease fit this profile. But the study results may have implications for other people with coronary diseases. They would have even higher levels of HDL – and having higher levels of the good cholesterol should only help them, Brown said.
Some patients in this study received simvastatin and niacin, while others received antioxidants. A third group received three treatments while a fourth, control, group received placebos. All patients received exercise training and dietary counseling.
The results for those receiving statin and niacin were startlingly different than the others. The average level of HDL increased from 31 to 38, while the average LDL dropped from 125 to 76 — that is considered an extremely good level of the bad cholesterol. Angiograms showed that most of these people had no additional plaque buildup over the years. In many of them, the amount of plaque actually decreased.
“What we saw was a reversal of the disease,” Brown said. “The patients’ arteries, on average, had stopped narrowing and begun to improve.”
The study involved use of niacin at moderately high and carefully supervised levels. Brown said that people should only take niacin under a doctor’s supervision, because in some patients, the doctor may wish to monitor the patient’s liver. Rarely, the unsupervised use of niacin can cause severe liver problems, including liver failure.
The study had included antioxidants because there has been considerable evidence that they should help protect against the basic mechanisms for cholesterol buildup. The antioxidants involved in this study include Vitamins C, E, beta carotene and selenium.
Others involved in the study include UW researchers Dr. John Albers, Dr. Xue-Qiao Zhao, Dr. Alan Chait, Dr. Lloyd Fisher, Alice Dowdy, Dr. Marian Cheung, Josiah Morse, Leny Serafini and Ellen Huss-Frechette, as well as Debbie DeAngelis and Dr. Jiri Frohlich of the University of British Columbia, Vancouver, B.C.

Is it possible to replace statins with dietary supplements
Atherosclerosis and dyslipidemia
September 17, 2020
ifoucare edition
Often people who are prescribed statins worry about side effects and intolerance, so they want to take dietary supplements instead. But experts believe that natural remedies can only supplement therapy, and not completely replace cholesterol-lowering drugs.
The problem with statins
Almost half of the adults who need to lower their cholesterol do not take any special medications 1 . This is due to many factors, such as cost, distrust of drugs, and most often fear of possible side effects 2, 3 .
Dietary supplements are applied in a complex
BAA are food additives. They contain vitamins, minerals, antioxidants, or other compounds, but are not drugs. Certain foods are known to help lower cholesterol levels. The researchers tested different supplements: red rice, omega-3 fatty acids, spirulina, soy proteins, green tea, lupine, garlic fibers, bergamot and berberine 4 , but there is no conclusive evidence of their unequivocal benefit and effectiveness yet.
Natural remedies may be given to patients who cannot tolerate statins, for example due to muscle pain, the most common side effect. Other lipid-lowering drugs, such as ezetimibe and PCSK9 inhibitors, are also an alternative for many. Because treatment options are limited, supplements can help lower cholesterol levels.
It is important to know!
Scientists emphasize that natural remedies cannot completely replace drug therapy with drugs from the statin group – a proven and reliable way to reduce cholesterol levels and the risk of heart disease. Patients should also not substitute any other cholesterol-lowering medications with natural remedies without consulting their doctor. Supplements and dietary changes may only be in addition to the prescribed treatment regimen.
Supplement with garlic extract
Garlic has been used as a traditional medicine for many years. Today, many people use garlic extract supplements as a natural remedy to lower blood pressure and cholesterol levels. Garlic also contains the amino acid cysteine, which produces allicin, a substance that lowers total cholesterol. However, clinical studies have shown conflicting results 5 .
Garlic has been shown to regulate triglycerides and total cholesterol, but has no effect on low-density lipoprotein (LDL) and high-density lipoprotein (HDL) 6 . This effect was observed only if a person consumed garlic for at least two months. This suggests that the benefit of garlic in lowering cholesterol is short-lived, and after six months, the effect of consumption disappears.
Niacin (Vitamin B3)
It is one of the most effective agents for raising “good” cholesterol levels: it can increase high-density lipoprotein levels by almost 20% 7 . Niacin also reduces low-density lipoprotein, or bad cholesterol, by 18% and triglycerides by 36% 7 . The effect is dose dependent, usually 1 to 4 grams per day is required 7 .
But niacin can cause side effects such as hot flashes, hyperglycemia, increased uric acid levels 7 . A hepatotoxic effect is also possible 7 . Hot flashes caused by niacin are difficult to tolerate by patients and are a major barrier to the use of this drug 7 .
Omega-3 fatty acids and fish oil
Omega-3 fatty acids include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). The most studied forms of omega-3 fatty acids are eicosapentaenoic acid and docosahexaenoic acid. They can lower serum triglycerides by up to 50%, but docosahexaenoic acid can raise both “good” and “bad” cholesterol levels 8 .
Omega-3s are generally well tolerated. The most common side effects are indigestion, diarrhea and heartburn 8 . Many patients complain of a fishy taste in the mouth, especially when taking high doses of supplements. Another effect that omega-3 causes is a decrease in blood clotting. Therefore, patients taking anticoagulants or antiplatelet agents should use omega-3 fatty acids with caution.
red rice
It is obtained by cultivating the yeast Monascus purpureus (red yeast) on white rice. This fermented product contains a group of monacolins, substances that inhibit cholesterol synthesis. Clinical trials have shown a significant reduction in total cholesterol, low density lipoprotein and triglycerides, an increase in high density lipoprotein 9 . But the level of the active substance in different samples of rice is not stable enough to speak of an unequivocal positive effect.
Do not self-medicate! Before you start taking any dietary supplement, be sure to consult your doctor!

9 effects of vitamin B3
Vitamin B3 is an essential nutrient. Every part of our body needs this substance to function properly. There is scientific evidence that this vitamin in supplement form can help lower cholesterol levels, relieve arthritis, improve brain function, and has other benefits. By the way, this vitamin is also called niacin, and sometimes the prefix PP is added instead of B3.
However, if you take large doses of this substance in supplement form, serious side effects may occur. Therefore, it is important to understand that more is not better.
It is one of the eight B vitamins. It has two main chemical forms, each of which affects our body differently. Both forms are found in both foods and supplements.
- Nicotinic acid: This is a form of niacin that is sold as a supplement. It is used to lower cholesterol levels and the risk of developing cardiovascular disease.
- Niacinamide or nicotinamide: This chemical form of the vitamin does not lower cholesterol levels. However, it may help treat psoriasis and reduce the risk of non-melanoma skin cancer.
This vitamin is water soluble, which means it is not stored in significant amounts by the body. It also means that our body is able to excrete excess amounts of this vitamin in the urine. Interestingly, a small amount of this nutrient is synthesized from the amino acid tryptophan.
Like all B vitamins, vitamin B3 helps convert food into energy by helping enzymes do their job. This nutrient is the main component of NAD and NADP. These two coenzymes are involved in cellular metabolism.
It also plays a role in cell-to-cell signaling and DNA synthesis. In addition to everything, this vitamin is involved in antioxidant reactions that protect us from the development of diseases and premature aging.
The RDA for this nutrient is 16 mg for adult men and 14 mg for women. During pregnancy and lactation, the norm increases to 18 mg and 17 mg, respectively.
If a person does not get enough of this substance, they may experience the following symptoms: 4
Severe niacin deficiency, or pellagra, is most common in people who do not eat a varied diet. However, in most developed countries, severe deficits are very rare.
Note that deficiency of vitamins and minerals develops with a monotonous diet, as well as with malnutrition. In order to get the concept of a balanced diet, we recommend that you seek the advice of a nutritionist. The specialist will explain the basics of dietology, after which you will be able, both with his help and independently, to create a healthy diet for yourself.
9 effects of vitamin B3 on health0145
This vitamin has been used since the 1950s to lower high cholesterol. In fact, it reduces the level of “bad” cholesterol (low-density lipoprotein, or LDL) by 5-20%. But this vitamin is not the primary treatment for high cholesterol due to its possible side effects. It is mainly used to lower cholesterol levels in people who cannot tolerate statins.
Effect #2 – increase « good cholesterol 0145
In addition to lowering “bad” cholesterol, niacin also increases “good” cholesterol. Studies show that it increases HDL levels by 15-35%.
Effect #3 – Triglyceride Reduction
This vitamin can also reduce triglyceride levels by 20-50%. This is achieved by reducing the activity of an enzyme that is involved in the synthesis of triglycerides. At the same time, the production of both LDL and very low density lipoproteins (VLDL) is reduced. To achieve these effects, therapeutic doses of this vitamin in supplement form are needed.
Effect #4 – reduced risk of developing heart disease
The effect of vitamin PP on cholesterol helps prevent the development of heart disease. In addition, new evidence is emerging about an additional mechanism by which this vitamin benefits the heart. It can reduce oxidative stress and inflammation in the body. Both of these factors are actively involved in the development of atherosclerosis, or hardening of the arteries.
Some studies show that taking this vitamin alone (at therapeutic doses) or in combination with statins can reduce risk in people who already have heart problems. However, the results are still mixed. In a recent scientific review, scientists concluded that niacin does not significantly reduce the risk of heart attack, stroke, or death from heart disease.
Effect #5 – Protecting cells that produce insulin
Type 1 diabetes is an autoimmune disease in which the body attacks and destroys cells that produce insulin. There is research to suggest that this vitamin may protect these cells and possibly even reduce the risk of developing type 1 diabetes in at-risk children.
But for people with type 2 diabetes, things are much more complicated. On the one hand, vitamin B3 supplementation reduces high cholesterol, which is often seen in people with type 2 diabetes. On the other hand, it can increase blood sugar levels. For this reason, people with type 2 diabetes need to be very careful never to self-prescribe supplements.
Effect #6 – improves brain function
Our brain needs this nutrient, which is part of the NAD and NADP coenzymes, to provide the brain with energy and its proper functioning. Confusion in the mind and even psychiatric symptoms can be associated with a deficiency of this vitamin.
Niacin is used to treat some types of schizophrenia. It helps repair brain cell damage resulting from a deficiency of this nutrient. Preliminary research suggests that it may also help maintain brain health in people with Alzheimer’s disease. However, the results are mixed.
Skin Health Benefit #7
This vitamin helps protect skin cells from sun damage. Moreover, he does this both in the form of tablets (capsules) and in the form of a lotion. Recent studies have shown that this vitamin can help prevent certain types of skin cancer. One study showed that taking nicotinamide 500 mg twice daily reduced the incidence of non-melanoma skin cancer in people at risk.
Effect #8 – Alleviate Arthritis Symptoms
In one preliminary study, this vitamin helped relieve some of the symptoms of osteoarthritis. The participants of the experiment improved joint mobility and decreased the need for non-steroidal anti-inflammatory drugs (NSAIDs). Another study in rats found that an injection of this vitamin reduced the inflammation associated with arthritis. While the data are promising, more research is needed to confirm all of these effects.
Effect #9 – treats pellagra
Severe vitamin B3 deficiency causes a condition called pellagra. People with this disorder develop problems with the skin, gastrointestinal tract, and nervous system. Taking this vitamin in supplement form is the primary treatment for pellagra.
As already mentioned, severe deficiency of this nutrient is extremely rare. But with alcoholism, anorexia, or Hartnup’s disease, the risk of its severe deficiency increases.
Niacin in foods
This vitamin is found in both animal and plant foods. Interestingly, some energy drinks also contain B vitamins, sometimes in very high doses. But that’s just a fun fact to be aware of. In no case do not get carried away with these drinks!
