The long-term effects, optimal dosing, and potential drug interactions are not fully understood
You can get these amounts from taking dietary supplements like multivitamins, B12 supplementation including sublingual tablets, or by eating certain foods rich in vitamin B12
It takes several years to completely deplete your livers stores of B12, so people who have recently started a vegan or vegetarian diet may still have moderate vitamin B12 levels.[ref] Dietary sources: Foods that are highest in B12 include:[ref] beef liver mussels lamb caviar chicken livers High Homocysteine and B12: Homocysteine levels: If your homocysteine levels are high and you carry the MTHFR or MTRR reduced function variant above, supplementing with vitamin B12, methylfolate, riboflavin, and B6 may help to lower your levels.[ref][ref][ref] Interaction with alcohol: Alcohol is metabolized into acetaldehyde, which is toxic and inhibits methionine synthase (MTR)
However, a direct comparison between both experiments is not recommended and further research is needed to elucidate the transcription-translation dynamics of the investigated biomarkers in long COVID-associated persistent VCD
If offering peptides outside approved indications, clinicians should present use as experimental, disclose regulatory status and paucity of clinical studies, describe known and unknown risks, and outline standard treatment alternative (e.g
