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)
It is also important to minimize the potential presence of proteases in protein purification, either from sources intrinsic to the production process (e.g., host-cell proteins) or from extrinsic sources of contamination (e.g., adventitious microbes)
