Overview

Doctor's Best Sustained-Release Niacin with niaXtend is a dietary supplement built around niacin in a controlled-release format. Each tablet provides 500 mg of niacin and uses niaXtend® to deliver the ingredient gradually rather than all at once. That release profile is designed to support cardiovascular health while helping the body receive niacin over a longer period.

The sustained-release approach is intended to make niacin easier to take by reducing the likelihood of the flushing response commonly associated with this nutrient. By slowing the release, the formula aims to provide a more comfortable experience while still supporting a favorable balance of blood lipids.

The product is also positioned as a non-GMO, gluten-free, vegan supplement. It is formulated for adults and taken once daily with food.
