About Doctor’s Best – Time-release Niacin with niaXtend, 500mg – 120 tablets
Doctor’s Best Time-release Niacin with niaXtend delivers 500 mg of nicotinic acid per tablet using a sustained-release matrix designed to provide a gradual, extended release of niacin throughout the day. The niaXtend technology utilises vegetable waxes to moderate the rate at which niacin is absorbed, making it a thoughtfully formulated choice for those seeking a controlled-release niacin supplement.
Niacin (Vitamin B3) is an essential B-vitamin that contributes to normal energy-yielding metabolism, the normal functioning of the nervous system, the maintenance of normal mucous membranes, and the maintenance of normal skin. It also contributes to normal psychological function and the reduction of tiredness and fatigue.
Formulated with a clean, minimal ingredient list and suitable for vegans and vegetarians, each tablet is free from gluten, animal-derived ingredients and unnecessary fillers, reflecting Doctor’s Best’s commitment to science-based nutritional supplements.
