Endur-acin extended release wax Matrix Niacin is a unique dietary supplement designed for men and women interested in advanced support for heart health and cholesterol balance.* Endur-Acin provides nicotinic acid - the only form of niacin with targeted benefits for heart health and lipid metabolism - in a proprietary vegetable-based wax Matrix. This unique combination not only ensures a gradual, measured release of nicotinic acid over a 6-8 hour period, but also helps eliminate digestive upset and skin flushing that can occur with immediate-release forms.* Endur-Acin is backed by clinical research confirming its ability to help maintain healthy cholesterol levels within the normal range.* ("flush-free" Forms of niacin may reduce flushing, but these forms have not been clinically shown to benefit heart health.) Endur-Acin is available in three strengths - 250 mg, 500 mg and 750 mg - for easy compliance with doctor recommendations. In addition, it's free of Salt, sugar, starch, preservatives, artificial colors or flavorings, and common allergens (milk, egg, fish, shellfish, tree nuts, peanuts, wheat and soy). as with all dietary supplements, consult your physician prior to use if you have or suspect a medical condition, are taking any medications, or are nursing or pregnant.
