It is a co-factor for methionine synthase, an enzyme involved in the methylation cycle, which is crucial for the metabolism of amino acids and the production of neurotransmitters
NAD + /NADH is involved in this process within the mitochondria, where NAD + is reduced to NADH in the tricarboxylic acid (TCA) cycle and is subsequently oxidized to NAD + in the ETC for ATP generation
The peptide also seems to help enzymes work properly and reduce oxidative stress
It does, however, mean the honest summary is that animal evidence is suggestive, not decisive
To cope with this burden a fit, rested, a well-fed person must maintain adequate immunological and biochemical defense
