Natural Factors B3 Niacin Acid 500 mg

Vitamin B3 comes in two different forms; niacin and niacinamide. Both of these possess the same vitamin activity, but sometimes, niacinamide is preferred due to a reaction to niacin that many people experience. The reaction is called a "niacin flush" and causes the skin to temporarily become red, or feel warm and tingly. Niacinide also contains more triglyceride and cholesterol lowering properties. However, unlike niacin, niacinamide is not recommended for problems of the circulatory system.

Niacin is essential for metabolism of fats, proteins, and carbohydrates. It has a significant effect on blood cholesterol levels when taken in large amounts, and it is believed to be able to prevent cholesterol in the liver from secreting into the circulatory system. Niacin also increases your body's level of lipoproteins, known as the "good cholesterol" and is a powerful preventative for cardiovascular disease, hypercholesterolemia, atherosclerosis.

Natural Factors B3

I have been taking B3 for some time and yes, it has a flushing effect, that feels hot and itches but it does seem to help me with insomnia more than other natural products and my dad uses it for depression. It does help to take it after a meal to have less of the flushing effect and I do experience less flushing once my body got used it.



Simple, cheap, pure

It's hard to find pure Niacin (B3) in stores. They tend to carry the non-flush form or other mixed formula. I like this one, simple and pure, doesn't break the bank!
