One possible explanation is that low serum vitamin B12 levels would trap folate as 5-methyltetrahydrofolate, prevent the generation of methionine from homocysteine, and therefore reduce protein synthesis and lean tissue deposition
Peptides in metabolic syndrome: emerging therapeutics
By focusing on peptide identity verification , assay testing , HPLC analysis , LC-MS verification , and ISO 17025 laboratory testing , researchers can better evaluate product consistency and label accuracy
Unlike many problems that affect aging adults, vitamin B12 deficiency is quite treatable

Its absorption rate is relatively low, and contains some cyanide which the body must process
