Practitioner Selected Product

Extended-Release ENDUR-ACIN® provides nicotinic acid for heart health and cholesterol balance. This controlled release over 6-8 hours helps eliminate skin flushing we may experience with niacin.

ENDUR-ACIN® Extended Release Niacin (vitamin B3) 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 and may 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.

What can you expect?
