Part 5/9:
Investigation into NAD⁺’s effects has primarily involved experimental studies with animal subjects. In 2013, a study involving elderly mice found that NR supplementation improved muscle function, showcasing the potential for NAD⁺ to combat the effects of aging. Similarly, experiments with C. elegans, a type of roundworm, demonstrated that elevating NAD⁺ levels extended lifespan and mitigated age-associated declines.
Though these findings reveal the beneficial effects of NAD⁺ in simpler biological models, they raise the crucial question of whether similar results can be observed in humans.
