Nicotinamide Riboside Chloride (NR)

Nicotinamide riboside is a member of the vitamin B3 family. 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.
