Best Niacin Supplements

Which are the best niacin supplements?

Niacin is vitamin B3, a water-soluble nutrient that supports the cell energy system and helps convert carbs, proteins, and fats into energy.

Poultry, fish, beef, and even hearty classics like marinara sauce contain niacin, but not everyone eats enough of these foods to have ample niacin intake. 

Meat and fish have the most niacin, so vegetarians and vegans may fall behind in niacin intake and generally have lower levels of vitamin B.

We’ve made shopping for B3 supplements easier with this list of the top products from popular niacin brands.

Let’s dive in – here are the top 10 niacin supplements to put on your radar:

FAQs About Niacin

 

Q: What Is Niacin?

Niacin, otherwise referred to as vitamin B3 or niacinamide, is one of eight essential B complex vitamins.

It’s water-soluble and comes in three types: niacinamide, nicotinic acid, and inositol hexaniacinate. The body uses niacin to convert food into energy. 

Organ meat, fish, and poultry like chicken and turkey are the most common natural niacin sources.

You can also get it in smaller quantities through grapefruit, green peas, Jerusalem artichokes, marinara sauce, milk, mushrooms, peaches, sweet potatoes, tuna, and yeast. 

The recommended daily upper limit is 35 mg for adults, and most people who eat some meat or niacin-rich vegetables and fruit will not develop a vitamin B3 deficiency.

However, those who follow a vegetarian or vegan diet, and even some on certain medications such as isoniazid for tuberculosis, may not get enough niacin.

For those individuals, the best niacin pills can help them get adequate nutritional value from this essential vitamin.

 

Q: What Are The Benefits Of Niacin?

Niacin delivers many health benefits, as every part of the body can benefit from this nutrient that helps enzymes function and supports cellular metabolism.

Low-density lipoprotein (LDL) or “bad” cholesterol is linked to coronary heart disease, but that risk can be lowered through niacin treatment for high cholesterol treatment, which was introduced in the 1960s and continues today. 

Niacin has been found to lower LDL cholesterol by 5-20%, although there are possible side effects so it’s usually used when statins don’t work.

Vitamin B3 can also boost HDL “good” cholesterol by 15-35%, which may lower the likelihood of heart disease.

Other niacin benefits include lowering triglyceride fats by 20-50% through inhibiting the enzyme that supports triglyceride synthesis.

Niacin prevents artery inflammation and oxidative stress and protects pancreatic cells that create insulin and are targeted by autoimmune diseases like type 1 diabetes.

It also supports brain function in those suffering from memory problems. 

Finally, vitamin B3 protects the skin from sun damage and may alleviate osteoarthritis symptoms, although more research is required.

 

Q: What Are Symptoms of Niacin Deficiency?

Symptoms of vitamin B3 deficiency include headaches, scaly skin rash, memory loss, and diarrhea.

The three D’s of diarrhea, dermatitis and dementia are known as pellagra, which is much more common in developing nations where nutrition is a concern.

Even so, it may appear in those with low or no meat intake, so it’s important to watch out for anything unusual and always seek immediate medical attention if you experience these symptoms.

 

Q: What Are The Side Effects Of Niacin?

The main side effect of niacin in nicotinic form is flushing. Niacin flushing is the feeling of redness, heat, tingling, and itching that may accompany the initial dosage.

It may feel similar to a sunburn and persist for an hour or slightly longer depending on the person and the previous niacin intake.

It usually takes around 30 minutes for these side effects to appear, but sustained-release or low-flush tablets can help. 

If niacin flush side effects persist, it’s best to see a doctor.

 

Q: Is It Good To Take Niacin Every Day?

Niacin in small quantities is safe to take every day, but it’s always best to speak to your doctor to ensure the right dosage for you.

If you take too much niacin in a high dosage, you run the risk of niacin toxicity, which should be treated right away due to the possibility of liver damage or stroke.

While a niacin overdose is not possible just by eating a lot of niacin-rich foods, you could overdo it on the daily over-the-counter supplements.

Look out for symptoms like itching, abdominal pain, diarrhea, gout, rapid heartbeat, dizziness, and severely flushed skin.

 

Q: Does Niacin Cause Weight Gain?

Niacin has been linked to appetite stimulation. While niacin on its own may not cause weight gain, some people may put on extra weight when taking niacin if they start eating more.

Numerous factors go into weight gain, and you should speak to your doctor about your niacin supplements and how the benefits outweigh the risks.

 

Q: Does Niacin Get Rid Of Belly Fat?

Niacin speeds up your metabolism, which helps the body turn carbohydrates and fat into energy rather than added weight.

To best get rid of belly fat, you should combine niacin supplements with a healthy, balanced diet and adequate exercise. Speak to your doctor if you have weight concerns or more questions.

 

Q: Does Niacin Suppress Appetite?

Niacin does not typically suppress appetite and is actually a potent appetite stimulator.

However, the many health benefits of niacin can help people maintain a healthy metabolism and improve cholesterol, which may contribute to healthier weight management.

There are other supplements you can take that could help with appetite control and suppression, such as MCT oil or glucomannan.

 

Q: How Much Niacin Should I Take?

16 mg is the recommended daily amount of niacin for adult males, while adult females should have 14 mg a day.

Sometimes an individual may benefit from the slightly higher upper limit, including 35 mg for adults 19+, 30 mg for teens 14-18, 20 mg for kids 9-13, 15 mg for children 4-8, and 10 mg for toddlers 1-3 years old. 

Check with your doctor to confirm how much niacin you should take.

Also, remember that pregnant or breastfeeding women and children should not have niacin supplements unless approved by a healthcare professional.

 

Q: How To Choose/ Which To Choose?

Deciding on the best niacin supplement comes down to how much niacin you need and your personal preferences.

If you only plan to take niacin in the short term, a smaller bottle of 100 veggie capsules may be fine.

Otherwise, if you want to take niacin every day for the foreseeable future, look for one that offers better bulk value with adequate niacin content to give your overall health a noticeable boost. 

Also, think about the kind of niacin supplements you want to take and any possible side effects.

Remember niacin can come in three different forms: niacinamide, nicotinic acid, and inositol hexaniacinate.

Nicotinic acid may cause flushing as the skin’s blood vessels widen temporarily, leading to tingling/itching sensations and headaches. 

Some timed-release versions have fewer side effects by slowly releasing the niacin into the bloodstream, but may be more likely to cause liver damage.

Non-flush types are niacinamide and inositol hexaniacinate, but they haven’t been found to improve cholesterol

Always check the ingredients as some niacin supplements contain gelatin so they aren’t suitable for vegetarians or vegans.

Your doctor can confirm whether niacin supplements are a smart addition to your diet and which ones may be best for you.

 

Summary

The best niacin supplements are all worthwhile investments, especially if you’re looking to supplement your vitamin B3 intake.

For those who don’t eat a lot of poultry, fish, or beef, niacin capsules can support proper enzyme function, help convert carbs into energy, and improve cholesterol.
