Nicotinamide Adenine Dinucleotide (NAD) - also known as Coenzyme 1 - is our body’s top-ranked coenzyme, naturally occurring and found in all living cells. This amazing coenzyme is a true a facilitator of numerous biological reactions, and particualry necessary for cellular development and energy production. NAD+ levels decline during the aging process. Elevating NAD+ / NADH can dramatically ameliorate age-associated functional defects, counteracting many diseases of aging, including neurodegenerative diseases and may be an effective anti-aging intervention.
