How it works

In our bodies, vitamin B3 helps create a substance called nicotinamide adenine dinucleotide, or NAD+ for short, which is used in many metabolic reactions. NAD+ affects cellular functions beyond energy metabolism as well, such as DNA repair, cellular aging, and immune system function. NAD+ also reduces the inflammatory response, so by synthesizing NAD+, vitamin B3 helps temper inflammation.

Pregnancy

Niacin is not safe for pregnancy in high amounts, such as those obtained in high-dose prescription niacin supplements. Niacin is likely safe for both breastfeeding and pregnancy in the typical recommended daily allowances, and is found endogenously in breastmilk.
