Adults get 1000 mcg of vitamin B12 intramuscularly once a week

So I don't understand why my doctors are not seeing this but the only treatment for it is B12 so here I am 3 years into it injecting B12 every day and my blood is still thick

As a veterinarian, I most frequently see a cobalamin deficiency with decreased intestinal absorption from inflammatory bowel disease, intestinal cancer, and pancreatic disease

Shaking introduces mechanical stress and creates air bubbles, both of which can damage the peptide structure

While some patients report improvements in skin clarity or texture after B12 shots, these changes are usually most noticeable when a deficiency existed beforehand

No serious adverse reactions were reported
