B-12 shots are a popular way to get the daily recommended amount of this vitamin, as they provide a concentrated dose that can be quickly absorbed into the bloodstream
Medical Conditions, Surgeries, and Medications Lack of intrinsic factor (a protein made in the stomach thats needed for B12 absorption) - this condition is called pernicious anemia Thyroid disease HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome) Autoimmune diseases like type 1 diabetes, where the immune system in the body attacks its own tissues Gastric bypass surgery (weight loss surgery) Chronic gastritis surgery Certain medications like heartburn drugs (proton pump inhibitors) which reduce stomach acid production Who Is At Risk of Vitamin B12 Deficiency
It is worth being clear here: in people with normal B12 levels, injections have not been shown to improve athletic performance or endurance
Unlike most peptides, which bind to a specific GPCR or tyrosine kinase, AOD-9604 acts via several indirect pathways with a predominance of effects on adipocytes (fat cells)
That all worked fine for over a year
without it, vitamin B12 levels eventually drop
