SUPPORT YOUR ENERGY LEVELS: Do you suffer from fatigue and low energy levels? There are many, many reasons for this condition that affects so many. One reason could be inside your cells - when they don’t have the necessary nutrients to metabolize energy correctly.* Nicotinamide may support the body’s natural mechanisms that improve energy production due to its role as a precursor of NAD, an important molecule involved in energy metabolism.*

Nicotinamide is well tolerated. Nicotinamide is a different form of vitamin B3 to nicotinic acid or niacin. Nicotinic acid commonly causes headaches, flushing and low blood pressure, but these side effects are generally not seen with nicotinamide.* Preliminary evidence suggests that nicotinamide may support the body’s natural ability to support healthy joint mobility and comfort, while other studies have shown that nicotinamide may support healthy blood glucose levels.*
