This significant discrepancy between physiological requirements and therapeutic doses highlights the need for a deeper understanding of B12 absorption dynamics, rather than focusing solely on intake quantity
In naturally aged mouse models (1820 months old), daily oral administration of 5-amino-1mq capsules for 12 consecutive weeks significantly reduced NNMT activity and increased NAD+ levels in various tissues (liver, kidney, adipose tissue), along with markedly elevated expression of SIRT1 and SIRT3 proteins
B12 does not sting but the other B vitamins do
Many individuals report a noticeable improvement in energy levels within days of starting injections
The ability to shuttle between the +1, +2, and +3 oxidation states is responsible for the versatile chemistry of vitamin B 12 , allowing it to serve as a donor of deoxyadenosyl radical (radical alkyl source) and as a methyl cation equivalent (electrophilic alkyl source)
