Vitamin B12 Deficiency.
This is an assume review of Vitamin B12 and really supports what I already do in my clinic (which is always good to hear…). I use a B12 supplement with 2,000 mcg of B12, which is 33,333% of the RDA (it also had folic acid and Vit B6) as a substitute for injections. I also use this particular supplement to show my disdain for the RDAs… Good thing certain popular, low quality multivitamins contain 100% of the RDAs, huh??
