Product Description

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.

Plain Niacin is available in two strengths – 250 mg and 500 mg – for easy compliance with doctor recommendations.


  • Easy-to-swallow tablets
  • No salt, sugar, starch, preservatives, artificial colors or flavorings
  • Gluten-free
  • Vegan/Vegetarian
  • Free of common allergens (milk, egg, fish, shellfish, tree nuts, peanuts, and wheat)

Are there any precautions?

Consult your healthcare professional prior to use if you have or suspect a medical condition, are taking any medications, or are pregnant or nursing. Temporary flushing, itching or warming of the skin may occur.

Fantastic product

I have used this product for over 10 years and it is the most cost-effective means for cholesterol health available. Yes, you might get some momentary flushes, but to me they are a non-issue.


I ordered the wrong kind. I reordered and sent them back. the lady I talked to was very nice.

Good plain niacin

Inexpensive and effective. Does cause flushing sometimes, but it stops after several days.

Awesome company

I wish more companies were as cooperative & efficient as Endurance Products Company.
