NAD+ is central to cellular energy biology, but “fountain of youth” language is much stronger than current clinical evidence.
Why NAD+ attracts attention
NAD+ participates in energy metabolism and enzyme systems related to cellular maintenance. Levels change with age, leading researchers to study ways of influencing NAD+ biology.
Where uncertainty remains
Biological importance does not prove that a particular injection, infusion, spray, or supplement improves a specific symptom or reverses aging. Evidence varies by intervention and outcome.
