Health Benefits of Vitamin B3 or Niacin

The health benefits of niacin include maintaining good blood circulation, healthy robust skin condition, and normal functioning of the brain, boosting memory power, aiding the digestive tract to absorb sufficient carbohydrates, proteins, and fats, reducing the effects of arthritis and improving the symptoms of schizophrenia. The most important benefit of niacin or vitamin B3 is its ability to lower cholesterol levels and control them.

Vitamin B3, also known as niacin, releases energy into the body’s cells, but niacin is primarily used to lower high cholesterol levels. You may get Vitamin B3 in supplement stores, but it is always sensible to buy niacin when specifically instructed by a doctor.

Foods such as fish, nuts, dried grains, liver, chicken, lean red meat, whole grains, enriched refined grains and dried beans are good sources of vitamin B3.

Vitamin B3 and its various forms, such as niacin, are popularly used as therapeutic vitamins to relieve many ailments. Niacin is also used to treat respiratory or vascular disorders, and as an effective dietary supplement for treating pellagra, along with Lovastatin.

However, those benefits are just the tip of the iceberg. Vitamin B3 has numerous other health benefits, which mankind has slowly discovered over the course of many years. Niacin mainly comes in 3 types or forms, which Chicken2include nicotinic acid, Niacinamide, and Inositol Hexaniacinate as supplement tablets or doses. Nicotinic acid helps to reduce high blood cholesterol levels, whereas Niacinamide may be found in nutritional supplements.

Health Benefits of Vitamin B3 or Niacin

Some of the beneficial properties are explained in greater detail below.

Digestion: As a member of B-complex vitamins, niacin aids in the normal functioning of the human digestive system, promoting a healthy appetite, properly functioning nerves, and a glowing skin.

Pellagra: People with weak muscles, digestive problems, skin irritation or pellagra may have a severe vitamin B3 deficiency. These people need to administer an increased dosage of vitamin B3 supplements into their diet.

Cholesterol: Intake of large quantities of niacin, which would be 1100 or more milligrams in a day, has been proven to considerably reduce the levels of “bad” LDL cholesterol and raise the good HDL cholesterol, which prevents the thickening of artery walls and conditions like atherosclerosis.

Water-soluble: Niacin is a water-soluble vitamin that can travel through the human blood stream and the body has the option to discharge excess vitamins through the process of urination. Therefore, such vitamins may be administered to human beings through both food and liquid, since our body does need a constant supply.

Food Sources: Vitamin B3 may be found in meat, turkey, tuna fish, eggs, poultry products, curds, brewer’s yeasts, peanuts, legumes, potatoes, cheese, brown rice, oats, barley, wheat flakes and milk. Foods like bread and cereals are also rich in niacin. Even tryptophan-rich foods like yogurt and eggs can boost niacin levels.

Daily Dosages: Ideally, women should have at least 15-18mg per day. It is extremely beneficial for women who are on various types of medication. Even those who occasionally use sleeping pills may develop a vitamin B3 deficiency. Men should consume 15-19 mg every day, whereas children should have a 9-13mg dosage of vitamin B3 each day.

Sex: Niacin helps in creating sex hormones for people suffering through sexual disorders like impotence and erectile dysfunction.

Energy: Vitamin B3 performs the important function of converting proteins, carbohydrates and fats into energy.

Mental Health: Even mental derangement and associated conditions may be cured with the administration of niacin supplements or medicinal drugs.

Diabetes: Niacin is known to treat diabetes and high blood sugar levels. Most diabetic patients are able to effectively control HBA1C levels with the help of niacin.


Although it is rare to have a niacin deficiency that requires supplementation, modern society may actually benefit from supplementary forms of niacin to treat various body ailments. All three forms of niacin have different effects on human body. Niacinamide has prominent anti-inflammatory contents, whereas Nicotinic acid & Inositol hexaniacinate may affect the circulation of the blood.

You may use niacin or vitamin B3 supplements with regular meals or even in liquids. Niacin may have a drugging effect when taken in very high dosages, and as always, it is best to consult a doctor or medical professional before taking any supplements or changing your diets in any considerable way.

      The B vitamins are being found to be increasingly important and are depleted by things like stress and illness. Large quantities of supplements are controversial due to links with liver and kidney damage. Best to get a list of all the foods containing B vits and make sure you include them in yr diet. I have a list if you can't find one. Love, The Food Police x

      Just watched Food Matters on Netflix…..in regards to depression, one of the key researchers on the documentary referred to Dr. Abram Hoffer's research on Niacin…he had become friends with the founder of AAA, Bill W…Dr. Hoffer suggested to Bill W that for his depression he should take 3,000mg/daily of niaciin for depression which Bill W found successfully improved depression and his fight with alcohol. Also, a woman in her 50's suffered from severe suicidal depression. She was living with her family, but was completely nonfunctioning. She would sit facing the corner of a room, and would not talk to anyone. Though she was seeing a psychiatrist, this family was advised to add Niacin in her diet (with the doctor on Food Matters)….which they had inquired about nutrition. Instead of 3,000 mgs, a larger dosing was suggested…the supplemented her with 11,500mgs of niacin and
      she improved to the point of talking, and eating with family. The psychiatrist questioned the high levels…citing his concern that this was over dosing. The family stopped, and the daughter returned to her former state. FOOD MATTERS IS WORTH WATCHING…ALOT OF GOOD INFO….AND ALWAYS USE COMMON SENSE
