This action minimizes the shift to less efficient anaerobic respiration, preserving cellular energy and reducing oxidative damage ( 9 )
Dehydration, however, can impair these processes, leading to a slower metabolic rate and prolonged presence of alcohol in the body
This is a commonly referenced study from 1963 claiming a half-life of 5-6 days: nature.com/articles/198200a0 Although I would not cite it as an authority, the six-day half-life has also made it onto the B12 page in Wikipedia, seemingly unchallenged
[1] The peptide has been studied for its potential in mitigating cell aging, inducing protein synthesis, minimizing free-radical damage, preventing bacterial infection, and improving the function of skin fibroblasts
