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.

Other Ingredients

Gelatin, vegetable stearate.

Non GMO

Warnings

Caution: Temporary flushing, itching, rash or gastric disturbances may occur. Liver function testing is recommended when niacin is taken in excess of 500 mg daily. Those with gout or liver diseases should avoid taking high doses of niacin.

Lobster face anyone?

Posted by 5494747617981789623 on Feb 13, 2017

I normally use a non-flushing B3 and thought I'd give this one a go. It is in capsule form to make it easier to swallow. However, I suffered severe flushing with hives and severe itching and pain. I tried for several days but it was too much for me, I ended up having a valium just to try to relieve some of the intense heat and pain and redness from this. Unfortunately I am super sensitive to things and this dose was perhaps too high for me. If they could make it a non-flushing formula I would continue to buy it, but sadly it is not a non-flushing formula.

Lp(a) reduction

Posted by 5032278071204601254 on Feb 02, 2017

I was recently diagnosed with Coronary Artery Disease due to very high levels of Lipoprotein (a) -a genetic condition. After 10 weeks taking 1.5g niacin daily my blood levels have dropped from 610mg/L to 260mg/L, far exceeding my expectations of a 30% reduction seen in clinical trials. My doctor was sceptical of my action plan (he advised statins which I refused) and amazed at these results. I will now add Lysine & Proline and measure Lp(a) levels again in 3 months time. A great product which I'm delighted with.
