Let's have a closer look at how vitamin B12 can be used as a hangover cure
hence, it is more preferable than cyanocobalamin for the treatment of vitamin B12 deficiency (1,2,3,4)
While diet provides enough B12 for most, some medical conditions prevent proper absorption, making injections necessary
Older adults, for instance, often have reduced stomach acid production, which can make it challenging to absorb B12 from food
Some researchers also track NAD+ metabolite levels via urinary nicotinamide excretion to confirm functional NNMT inhibition, though this is not standard practice
NICE guidelines on obesity management do not include B12 supplementation as a therapeutic option for weight reduction without confirmed deficiency
