Natural Factors Niacin, No Flush , 500 mg, 90 Capsules

Natural Factors No Flush Niacin 500 mg is a dietary supplement designed to provide vitamin B3 without the flushing sensation associated with standard niacin. It uses inositol hexaniacinate, a form of niacin bound to inositol, which the manufacturer notes is intended to support energy production, nervous system function, and help regulate cholesterol levels already within normal range.

This product features a 500 mg dose of niacin from inositol hexaniacinate, which also supplies 120 mg of inositol. The no-flush formulation aims to make it more tolerable for users sensitive to niacin's common side effects. Natural Factors manufactures it in a GMP-certified facility, and it is free from artificial colors, preservatives, sweeteners, and common allergens like dairy, gluten, soy, and GMOs. Available in a 90-capsule size, it is also offered in a 100 mg strength variant for different dosage preferences.
