Micronutrients & recovery
Supplementation with NAD+ intermediates (NMN or NR) restores declining NAD+ levels in aged animals, thereby reversing age-associated metabolic dysfunction, improving mitochondrial function, and extending healthspan.
Aging is associated with a measurable drop in cellular NAD+, which impairs energy metabolism and mitochondrial function. Supplementing with precursors like Nicotinamide Mononucleotide (NMN) or Nicotinamide Riboside (NR) can restore NAD+ levels. In animal studies, this restoration reverses metabolic dysfunction, improves energy expenditure, and enhances physical activity, suggesting a viable strategy to mitigate age-related decline.
supplementation with NAD+ intermediates, such as NMN and NR, can effectively restore the NAD+ pool and cellular functions in aged animals.
Why this rating
The paper is a review citing multiple peer-reviewed studies (references 45, 82, 86, 87, 88) showing consistent benefits in mouse models, though human clinical data is implied as future potential rather than primary evidence here.
