After 4 weeks of cobalamin treatment, there appeared to be a trend towards lower concentrations for both these metabolites
It has a reported prevalence of 329%[1]
B12 has other benefits, too, including improved sleep, concentration, cellular function, and immunity
Additionally, chronic conditions such as HIV and tuberculosis have been implicated in B12 deficiency due to increased metabolic demand and altered absorption mechanisms ( The diagnosis of vitamin B12 deficiency typically relies on low total B12 levels and elevated concentrations of homocysteine (Hcy), as well as levels of transcobalamin-bound B12 (holoTC) and methylmalonic acid (MMA), which serve as functional indicators of cobalamin insufficiency ( Vitamin B12 requirements fluctuate throughout the life course, influenced by metabolic demand and physiological changes
According to the manufacturer, the usual daily recommended amounts of methylcobalamin, vitamin B12 for lactating women should be taken maternally during breastfeeding (see Dosage)
B12 shots dont always resolve the underlying problem of deficiency, so theyre not the be-all and end-all when it comes to treating symptoms
