ENDUR-ACIN® Extended Release Niacin is ideal for men and women interested in advanced nutritional 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. The unique wax-matrix delivery system not only ensures a gradual, measured release of nicotinic acid over a 6 to 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.
