Vitamin B3 Niacin

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.

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. In its coenzyme forms, niacin is crucial to energy transfer reactions, particularly the metabolism of glucose, fat, and alcohol. Niacin's beneficial effects on blood lipids is well-documented.

Suggested Use

Read the entire label and follow the directions carefully prior to use.

Take one (1) capsule daily with meals, or as recommended by a healthcare practitioner.

************* Great product -- PLEASE CONSULT YOU DOCTOR

Posted by Sickness-ELIMINATOR on Aug 11, 2013

I have been using this product for a year after switching from GNC's niacin (B3). GNC's product was good, but very expensive. I no longer experience the 'Niacin Flush' that people are complaining about. Before taking any megadose supplement/vitamin, you should CONSULT YOUR DOCTOR. Taking large doses of vitamin B3 (niacin) requires you to have good liver function. If your liver function is poor, you could permanently damage it. My doctor specifically told me to STAY AWAY FROM THE ''NO-FLUSH'' NIACINAMIDE. I hope this review helps some people to realize that taking megadoses of niacin should be taken with an informed consent, and the green light from your doctor. . . . . You can find other products I use on my Page! I use only products that have Scientifically Proven benefits.

Excellent product

Posted by Reviewer2316335 on Mar 19, 2010

I take niacin at 500mg/day for the last two months. It has helped me to increase HDL, nad lower LDL and triglycerides. Also, niacin is the only supplement that has proved to decrease the thicknes of atheromatic plaque. My 14 yo son takes the same amount to help his acme. After one month, results are really impressive. We both flash, but it is not that bad. As a matter of fact, we enjoy it.
