b12 injections memory loss What Are the Benefits of Vitamin Injections? What You Need to Know

Vitamin B12 Hi I have had really bad heavy periods for the last few years and low b12 was thought to be part of the problem, I was recently put on the pill to control them (which does make them a bit lighter but I am getting bleeding when I shouldn't!)

However, absorption requires intrinsic factor, a protein produced in the stomach

Finally, the analysis showed colchicine caused a higher rate of gastrointestinal side effects, but not serious adverse side effects, than control

Bypassing a large portion of the stomach and small intestine will cause absorption of fewer calories and nutrients

B12 deficiency is associated with hair loss, but there's not enough evidence to show that taking B12 supplements will help hair grow back
