25 Vitamin B3 Foods You Should Add to Your Daily Menu in 2024

Vitamin B3 Foods

Vitamin B3, or niacin, belongs to B-complex vitamins. Niacin is one of the essential nutrients that our body needs to function normally. Some of its health benefits are enhancing mental health, lowering the risk of heart diseases, and decreasing bad cholesterol.

That’s why it is important to include vitamin B3 foods in your diet. If you are not sure where niacin can be found, this article will provide you with a list of healthy foods that contain this vital nutrient.

What Is Vitamin B3?

Being one of the water-soluble vitamins, niacin is not stored in the body in large quantities. Most excess amounts of this vitamin are excreted through the urine. Niacin, another vitamin B3 name, was created by blending three words into one – nicotinic acid vitamin.

That said, nicotinic acid isn’t the only form of vitamin B3. Other forms include nicotinamide, inositol hexanicotinate, and related derivatives. Interestingly, they all have different uses in the body.

Vitamin B3 Benefits

Like all B vitamins, vitamin B3 aids the body in breaking down carbohydrates, fats, and proteins and converting them into energy. Another vitamin B3 function is the regulation of cholesterol levels in your body. Not only does it lower bad cholesterol, but it also increases good cholesterol. Therefore, niacin may reduce the risk of heart disease. In addition to cholesterol management, vitamin B3 can decrease the levels of triglycerides.

Furthermore, niacin benefits are key to mental health. Some of them include treating some mood disorders, like depression and anxiety. What’s more, some of the benefits of taking niacin involve treating some types of schizophrenia. There are even studies examining the role of niacin in preventing Alzheimer’s disease.

Niacin’s health benefits also include protecting our skin from sun damage and preventing certain types of skin cancer. Numerous studies on common skin cancers have shown the positive effects of nicotinamide, niacin’s active form.

Niacin Foods

Many foods contain vitamin B3. Both animal-based and plant-based foods are good sources of niacin. This nutrient is also added to certain types of foods, such as cereals and infant formulas.

In addition, foods that are rich in tryptophan are considered excellent sources of vitamin B3—niacin. That’s because tryptophan can be converted to NAD (nicotinamide adenine dinucleotide), which is the active form of niacin.

All in all, all of us need to know what foods have vitamin B3, so here’s a list of some great sources of this essential nutrient.


Beef liver is especially rich in niacin. In fact, one slice of pan-fried beef liver covers 71% of the daily value (DV) of vitamin B3, securing its place among niacin foods. What’s more, three ounces of pan-browned ground beef (90% lean meat) will land you 29% of the vitamin’s DV.

Daily Intake Recommendations

The Dietary Reference Intakes, created by the Food and Nutrition Board (FNB) at the Institute of Medicine of the National Academies, provide you with intake recommendations for B3 vitamin and other vital nutrients.

The recommended dietary allowances (RDA) for niacin differ depending on age and sex. They are expressed in mg of niacin equivalents (NE), where one niacin equivalent equals 1 mg of niacin or 60 mg of amino acid tryptophan, converted to niacin in the body.

No matter whether your niacin intake is based on a balanced diet or vitamin B3 tablets, here you can find the recommended dietary allowances for this crucial nutrient:

  • from birth to 6 months — 2 mg
  • from 7 to 12 months — 4 mg NE
  • from 1 to 3 years — 6 mg NE
  • from 4 to 8 years — 8 mg NE
  • from 9 to 13 years — 12 mg NE
  • 14+ years — 16 mg NE (male) and 14 mg NE (female)

Note that women need more vitamin B3 during pregnancy and lactation. They should increase their daily intake to 18 mg NE while pregnant and to 17 mg NE while breastfeeding.

Niacin Deficiency 

The symptoms of this deficiency can be both physical and mental. Some of the vitamin B3 deficiency symptoms are skin problems, headaches, fatigue, diarrhea, depression, memory loss, and mental confusion. This nutrient deficiency is mainly related to poverty, as an inadequate diet usually causes it.

Severe vitamin B3 deficiency leads to a disease called pellagra. The symptoms of this condition include a pigmented rash on skin exposed to sunlight, a bright red tongue, and problems with the digestive tract, such as constipation, diarrhea, or vomiting. Pellagra can also cause neurological problems, including depression, memory loss, and hallucinations. If it is not treated correctly, it can even lead to death.

Who Should Take Niacin Supplement?

People who don’t follow a healthy, balanced diet can suffer from this vitamin deficiency. It usually affects people who live in poverty, but an inadequate level of vitamin B3 may also be caused by excessive alcohol use, AIDS, or inflammatory bowel disease. In addition, people with an inadequate intake of other nutrients might have problems with the conversion of tryptophan to niacin. They all can benefit from taking a vitamin B3 supplement.

Supplements are also recommended to people with severe medical conditions, such as Hartnup disease and carcinoid syndrome. Hartnup disease harms the absorption of tryptophan, and it increases its excretion in the urine. On the other hand, people with carcinoid syndrome have a problem with a lack of tryptophan as it is oxidized to serotonin instead of being converted to niacin.

Vitamin B3 Side Effects

Consuming foods that are rich in niacin cannot usually cause any adverse effects. However, high doses of a vitamin B3 supplement in the form of nicotinic acid or nicotinamide can have negative effects on your health.

A common side effect of nicotinic acid is flushing, which is the result of blood vessel dilation. Besides flushing, people often feel itching, tingling, and burning sensations. Sometimes, other niacin side effects, such as headaches, dizziness, and low blood pressure, can also be present.

Really high doses of nicotinic acid (1,000–3,000 mg/day) can have more adverse effects. They include hypotension, insulin resistance, nausea, heartburn, abdominal pain, and impaired vision. People who take high doses of nicotinic acid to reap B3 vitamins’ benefits may instead have increased levels of liver enzymes, develop hepatitis, or experience acute liver failure over a more extended period.

Nicotinamide is less toxic than nicotinic acid. That being said, a daily dosage of 3,000 mg can cause nausea, vomiting, and signs of liver toxicity.

Finally, note that the FNB has defined Tolerable Upper Intake Levels for supplemental niacin. These values apply to healthy individuals who aren’t taking a niacin supplement for medical reasons.


Niacin, or vitamin B3, plays a crucial role in many metabolic processes, so it is of great importance to include foods rich in this nutrient in your eating plan. Conversely, a poor diet lacking niacin-rich sources can lead to B3 deficiency, whose most serious form is pellagra.

That being said, make sure you consult a healthcare professional about the possibility of taking supplements. A doctor will help determine the exact dose and dosage to address your needs and avoid potential side effects.


What does vitamin B3 do?
