Nicotinic acid is a form of Vitamin B3 that has vasodilation properties. This means that it expands the capillaries (fine blood vessels) under the skin so more blood flows to the skin making it red and itchy. This effect is called the ‘niacin flush’.
Though the niacin flush is uncomfortable it’s not harmful. It’s also a temporary effect in two ways; it disappears an hour or so after it starts and after continued usage it often stops happening at all.
Niacin contributes to: normal psychological function, normal energy-yielding metabolism, normal functioning of the nervous system and reduction of tiredness and fatigue.
Health4All Vitamin B3 Niacin 500mg capsules provide a high-strength dose of Niacin as nicotinic acid, the classic flush form of Vitamin B3. This product is designed for customers specifically looking for strong flush niacin capsules rather than no-flush nicotinamide or niacinamide.
Niacin contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue. It also contributes to the maintenance of normal skin and normal mucous membranes.
Because each capsule contains 500mg nicotinic acid, this product is likely to produce a strong niacin flush. This may be felt as noticeable warmth, tingling, redness or flushing of the skin. Customers who do not want this effect should choose a no-flush Vitamin B3 product instead.
Nicotinic Acid, Vegetable cellulose capsule.

12 reviews for Vitamin B3 Niacin (Nicotinic Acid) 500mg Capsules
Very good product, especially as it’s difficult to find niacin with flush effect. The 500 mg dosage is just right for me to control cholesterol level. Before taking this dosage, I started with the smaller 50 mg tablets (also from health4all) and slowly built my tolerance to the flushing. If you haven’t taken flushing niacin before, it’s better to start with low dosage to figure out the level at which flushing starts, as it can be uncomfortable.

My husband has been taking this product (Nicotinic Acid, the flush version of Niacin – NOT Niacinamide) for many years and in the process lowered his cholesterol from very high to within recommended limits. This product is so successful at doing this that he hasn’t needed to take any statins for years now.

Very effective, and very clean. Compared to the Solgar brand, at the same strength, these are far superior.
