Vitamin B3 Niacin


B complex vitamin benefits are considerable. So it is important to not ignore vitamin B complex benefits.

Tryptophan is converted by the body to Vitamin B3 Niacin so many sources suggest that it is not an essential nutrient if you get enough tryptophan. Organ meats, eggs fish and peanuts are good sources for both.

But B3 is so important in the production of energy, regulating blood sugar, regulating and reducing cholesterol, aiding antioxidants and detoxifying that taking it as part of a general supplement can be very useful.

Niacin in doses over 50 mg can cause skin flushing so niacinamide is often used in its place. Each is a different form of B3.

Some Facts

• water-soluble vitamin

• like B1 and B2 important for food metabolism and release of energy in cell Alt Med

• regulates blood sugar – but diabetics should only use under medical supervision

• vital for oxygen transport in the blood Alt Med

• vital for fatty acid and nucleic acid formation Alt Med

• major constituent of several major coenzymes Alt Med

• aids in detoxification

• deficiency of B3 and tryptophan cause pellagra

• lowers LDL (bad) cholesterol and triglycerides better than drugs Arch Intern Med 1994

• raises HDL (good) cholesterol better than drugs Arch Intern Med 1994


Slow release forms of niacin, that reduce or eliminate flushing of the skin, can cause liver damage. For many niacinamide is a better option.

My Own Experience

Well I sure did find that Niacin caused a lot flushing that brought on lots of "funny" comments during lunch.

But the good news is that when I got away from taking Niacin alone and changed to a much better formulated B3 (niacin and niacinamide mixed form) in a top quality multivitamin, along with Omega 3 supplements my triglycerides were reduced 68.5%. Vitamin B3 and other nutrients in my multivitamins and multi-minerals reduced my LDL (bad) cholesterol by 12% and increased my HDL (good) cholesterol by 33%. Given my personal genetics bequeathed to me my parents and grandparents these are excellent and important results.
