Nicotinamide Riboside

Nicotinamide Riboside molecule

Nicotinamide riboside is a member of the vitamin B3 family, which also includes niacin and niacinamide. It's found in fruits, vegetables, meat, and milk.

Nicotinamide riboside is changed in the body to a chemical called NAD+. The body needs NAD+ for many processes to work normally. Low levels can cause health problems. Taking nicotinamide riboside can help raise low NAD+ levels.

People use nicotinamide riboside for anti-aging effects, high cholesterol, high blood pressure, Alzheimer disease, obesity, and many other purposes, but there is no good scientific evidence to support these uses.

Don't confuse nicotinamide riboside with niacin, niacinamide, or NADH. These are all related but are not the same.
