This Source Naturals product provides a very high dose of 1500mg Niacinamide per tablet. Niacinamide is a "no-flush" form of Vitamin B3, known for its role in cellular energy, DNA repair, and especially beneficial for skin health without causing the uncomfortable flushing.
It is typically chosen by individuals who require or seek a very substantial dose of B3 without the side effects of traditional nicotinic acid. This high strength is often considered for specific, more intensive B3 regimens where significant metabolic support is desired.
This product fits those who are looking for maximum niacinamide support, particularly for broad metabolic function or targeted skin health benefits at a significant potency. Users should be mindful of the high dose and consult with a professional if needed.
