NAD+
Nicotinamide adenine dinucleotide
A ubiquitous redox coenzyme central to cellular energy metabolism and a substrate for enzymes such as sirtuins and PARPs; it is a coenzyme, not a peptide. Studied in aging, metabolic, and neurological research; cellular levels reportedly decline with age.
Tracking and educational reference only, on values you enter or import yourself. Not medical advice or a dosing recommendation.
Regulatory status
Research only
This substance is sold and handled as a research material and is not approved for human use. There is no approved label, which means there is no agency-reviewed information about how it should be handled, who should avoid it, or what happens alongside other medicines.
Not approved for human use
A regulatory status describes paperwork, not safety. An approved compound can still be wrong for a given person, and an unapproved one is neither thereby dangerous nor thereby fine.
Half-life
Intracellular turnover ~1-4 h (compartment-dependent); a single plasma half-life is not well defined. Half-life is an educational pharmacology figure, drawn from public sources, and is not a schedule or dosing instruction.
Storage & handling
Sensitive to heat, light, and moisture; injectable forms kept refrigerated or frozen and protected from light; reconstituted solutions used within a limited window.

Common questions
NAD+, answered plainly.
01What is NAD+?+
A ubiquitous redox coenzyme central to cellular energy metabolism and a substrate for enzymes such as sirtuins and PARPs; it is a coenzyme, not a peptide. Studied in aging, metabolic, and neurological research; cellular levels reportedly decline with age. It is also referred to as Nicotinamide adenine dinucleotide. It is listed here under Cognitive / Longevity as educational reference, which is not a recommendation to use it.
02Is NAD+ FDA approved?+
Research only. This substance is sold and handled as a research material and is not approved for human use. There is no approved label, which means there is no agency-reviewed information about how it should be handled, who should avoid it, or what happens alongside other medicines.
03What is the half-life of NAD+?+
Intracellular turnover ~1-4 h (compartment-dependent); a single plasma half-life is not well defined. A half-life is an educational pharmacology figure describing how long the body takes to clear half of a substance. It is not a schedule and does not imply one.
04How is NAD+ stored and handled?+
Sensitive to heat, light, and moisture; injectable forms kept refrigerated or frozen and protected from light; reconstituted solutions used within a limited window. Storage conditions come from a manufacturer's own label where one exists, and a compound with no approved label has no agency-reviewed handling instructions at all.
05What vial strengths of NAD+ are commonly sold?+
Commonly listed vial strengths are 100, 500 mg. A vial strength is a market fact about how a product is packaged. It is not a dose, and it says nothing about how much of anything belongs in any person.
