About This Product

Is engineered to release the nutrient gradually over an extended period. This controlled delivery helps reduce the intensity of the "Niacin Flush"—a common side effect of itching or redness associated with high doses of Vitamin B-3. Niacin plays a vital role in converting carbohydrates, proteins, and fats into cellular energy, while also supporting healthy cardiovascular function and nervous system health. These tablets are laboratory tested and manufactured under strict quality standards to ensure purity and potency.
