In fact, one study found that peoples bodies absorbed about 49% of a 1-mcg dose of cyanocobalamin, compared to 44% of the same dose of methylcobalamin ( Conversely, another study comparing the two forms reported that about three times as much cyanocobalamin was excreted through urine, indicating that methylcobalamin may be retained better within your body ( However, some research suggests that differences in bioavailability between the two forms may be insignificant and that absorption could be influenced by factors such as age and genetics ( Unfortunately, recent research directly comparing these two forms of vitamin B12 is limited
Theoretical considerations include: Potential interactions requiring monitoring: Other fat-loss agents or thermogenics (additive effects), growth hormone or growth hormone secretagogues (mechanism overlap), medications affecting glucose metabolism (monitor blood sugar despite AOD-9604s neutral glycemic effects)
Pernicious anemia is an autoimmune disorder that prevents the absorption of vitamin B12 due to a lack of intrinsic factora protein produced by the stomach lining
Both are valid
