21st Century Niacinamide 500 mg (110 tablets) contains niacinamide, a form of vitamin B-3, supplemented with calcium (as calcium carbonate). One tablet provides 500 mg niacinamide and 160 mg calcium. The tablets are produced with a prolonged release, which means the active ingredients are gradually released. The packaging contains 110 tablets, enough for almost 4 months’ supply at 1 tablet per day. The tablets are suitable for vegetarians and vegans.
Niacinamide is a form of niacin, also known as vitamin B3, and is part of the B-vitamin group.
Niacinamide and nicotinic acid are both forms of niacin (vitamin B3), but differ in their chemical structure. Nicotinic acid can cause temporary redness or a warm sensation of the skin in some people, a reaction known as a "flush". Niacinamide usually causes this reaction to a lesser extent.
Niacin naturally occurs in foods such as poultry, beef, fish, nuts, legumes and grains.
Prolonged release means that a tablet is formulated so that the active ingredients are released gradually, instead of all at once.
Calcium is a mineral and an essential nutrient. It naturally occurs in foods such as dairy products, green leafy vegetables, nuts, seeds and legumes. In food supplements, calcium is usually added in the form of a compound, such as calcium carbonate.
