Niacin - NiaXtend® by Doctor's Best

Niacin (nicotinic acid) is a water-soluble vitamin (B3) that plays a role in over 200 biochemical reactions in the body. It contributes to normal energy production, the proper functioning of the nervous system as well as normal psychological functioning. Vitamin B3 is also important for the metabolism of fats, carbohydrates and proteins.

Less niacin flush

There are two forms of vitamin B3: niacin (or nicotinic acid) and niacinamide (or nicotinamide). Niacin may cause a kind of hot flush after ingestion: the skin and face become warm and red. This is accompanied by an annoying tingling, burning and itchy feeling. Doctor's Best Niacin with NiaXtend® does not cause this flush. This tablet has a controlled release: the niacin is released slowly over an eight-hour period, preventing unpleasant side effects.

NiaXtend® Controlled Release

Niacin is a unique niacin formula using a wax matrix technology. This technology releases the niacin in a controlled, delayed manner such that not everything is released in the body at once. Prevention of this niacin peak is essential when higher doses are used. NiaXtend has a dosed release and effect.

Beneficial for the nervous system

Nutrition rich in niacin or niacin supplementation has positive effects on the nervous system and learning ability, including in elderly. This may be due to the direct influence of niacin on certain nerve cells. Niacin is also a powerful antioxidant that helps fight free radicals.

Two essential coenzymes, NAD and NADP

Niacin, B3, produces two essential coenzymes in the body: NAD (nicotinamide adenine dinucleotide, coenzyme I) and NADP (nicotinamide adenine dinucleotide phosphate, coenzyme II). In the body Vitamin B3 can be synthesized only to a limited extent, from tryptophan.
