Niacinamide provides a source of Vitamin B3 that supports cellular energy metabolism and overall metabolic health. This form of niacin does not cause flushing and is primarily used for general wellness and skin health.

While niacinamide is relevant to metabolism, it lacks the clinically validated lipid-lowering effects of nicotinic acid or inositol hexanicotinate. The 500mg dose contributes to daily B-vitamin status but offers limited functional impact for heart health.
