Doctor’s Best Sustained – Release Niacin, 500mg – 120 tablets

Doctor’s Best Sustained-Release Niacin delivers 500mg of niacin per tablet as nicotinic acid, using the brand’s NiaXtend technology to release the nutrient gradually over time. This controlled delivery is designed to reduce the well-known skin flushing sensation that niacin is notorious for, making each tablet considerably more comfortable to take than standard immediate-release alternatives.

Each pack contains 120 tablets, giving a generous supply at one tablet per day. At 3125% of the nutrient reference value per serving, this is a high-strength formulation aimed at those who want a significant niacin intake as part of a structured nutrition plan. The tablet format keeps things straightforward — no mixing, no measuring.

Doctor’s Best is a well-regarded American supplement brand with a long track record of science-backed formulations, and this niacin product reflects their focus on ingredient quality and thoughtful delivery methods. A solid option for anyone seeking a high-dose, sustained-release niacin supplement from a trusted name.
