Vitamin B3 Niacin
500 mg 100 capsules
Item Catalog Number:
00372

Many B vitamins are used in the body individually or in combination with enzymes to help release energy from carbohydrates, fat, and protein. Vitamin B coenzymes are crucial to the metabolic pathways that generate the energy needed by every cell in the body. Because they are codependent in their metabolic activities, a deficiency of one B vitamin can affect optimal functioning of organ systems throughout the body.170

Niacin is the only B vitamin that can be synthesized in the liver from the amino acid tryptophan — on average, 1 mg of niacin can be synthesized from the ingestion of 60 mg of tryptophan.198-200 In its coenzyme forms, niacin is crucial to energy transfer reactions, particularly the metabolism of glucose, fat, and alcohol.201,202 Niacin’s beneficial effects on blood lipids is well-documented.203-215

      Comments about Life Extension Vitamin B3 Niacin, 500 mg 100 capsules:

      I previously used Niacin for a long time (originally to quit smoking), but weaned off it for about 10 years. I saw my BP start to creep up with age to the 140/85-ish range. I re-introduced Niacin and built up to 1000mg/day (500mg with lunch and dinner). That's really the only change I made and I'm back in the 110/70 range. I take no prescribed medications.

      I do get a flush now and then, but it's no big deal, especially for how well this stuff works. It is a staple for me now, I wouldn't be without it.

          I take this product in the morning with a fruit smoothie. The flushing would bother me in the beginning but no longer is an issue.
