Product education

Niacin-SR: Slow-Release Support for Cholesterol Metabolism*

Niacin-SR provides a 500 mg dose of niacin (Vitamin B3) in a scored, slow-release tablet. This special delivery system allows for the gradual release of niacin over several hours, which helps to avoid the uncomfortable flushing action often associated with this B vitamin. This allows the full benefits of niacin for supporting healthy cholesterol metabolism to be obtained with greater comfort and compliance.*

How It Works: Slow Release for Better Tolerance

This formula is designed to deliver a steady amount of niacin to the body, minimizing the common side effects of standard, immediate-release formulas.

Supporting Healthy Cholesterol
Niacin is a well-researched B vitamin that plays an important role in the metabolism of lipids. It has been shown to provide significant support for maintaining healthy cholesterol levels that are already within the normal range.*

Avoiding the “Niacin Flush”
A common side effect of niacin is a temporary but uncomfortable skin flushing, tingling, and itching. The slow-release mechanism in Niacin-SR helps to mitigate this reaction by preventing a rapid spike of niacin in the bloodstream, making it a better-tolerated option for long-term use.*

  • Supports healthy cholesterol metabolism*
  • Provides a potent 500 mg dose of niacin (Vitamin B3)
  • Scored tablet can be broken for flexible dosing
