Effects of NAD+ precursor supplementation on glucose and lipid metabolism in humans: a meta-analysis

In older age, vitamin B12 absorption tends to be less efficient due to a range of health issues, including gastritis stomach lining inflammation and thinning but also because of decreased production of stomach secretions (EFSA, 2015

AOD9604 appears to stimulate proteoglycan and collagen synthesis in chondrocytes through growth factor signaling pathways distinct from its lipolytic mechanism, supporting cartilage matrix repair in joint models

This caught the attention of the insurance companies which have mostly stopped covering the cost of B12 injections, sometimes even in the case of unambiguous deficiency that is refractory to oral supplements

Unlike fulllength hGH, AOD9604 does not meaningfully elevate IGF1 levels or worsen glucose tolerance, making its tolerability indistinguishable from placebo in human trials [2] [3]
