Life Extension NAD+ 300 mg (30 capsules) contains NIAGEN® nicotinamide riboside, an active form of vitamin B3 (niacin). Each capsule provides 300 mg nicotinamide riboside, of which 126 mg corresponds to niacin.
NAD+ is a naturally occurring substance in the body that is involved in cellular energy production. It plays a role in converting nutrients into energy (ATP) in the mitochondria – the powerhouses of the body. As we age, the natural production of NAD+ gradually decreases. That is why many people, especially from age 40, choose to supplement with nicotinamide riboside, a highly absorbable form of vitamin B3.
Vitamin B3 supports energy metabolism and helps reduce tiredness and fatigue. Additionally, it helps maintain normal skin and supports a well-functioning nervous system. It also plays a role in mental balance and concentration.
The NIAGEN® form is a patented and standardized form of nicotinamide riboside that is well absorbed.
