Promotes Heart Health and Cholesterol Balance

  • Advanced immediate-release formula
  • Helps eliminate skin flushing
  • Formulated to complement doctor-recommended therapeutic lifestyle changes

Plain Niacin 500mg Nicotinic Acid is ideal for men and women who prefer an immediate-release nicotinic acid formula to support healthy cholesterol balance and lipid metabolism.

Plain Niacin combines immediate-release nicotinic acid (also known as crystalline niacin) with our proprietary vegetable-based wax matrix. The tablet dissolves more slowly than regular formulas, gradually releasing nicotinic acid in just under one hour rather than all at once. In this way, it delivers heart health benefits without excess skin flushing or digestive upset typical of regular formulas.

Nicotinic acid is the only form of niacin with targeted benefits for heart health. So-called “flush-free” forms of niacin may reduce flushing, but these forms have not been clinically shown to benefit heart health.
