WeightWorld Vitamin B12 1000 mcg - 450 Tablets (1+ Year Supply) - Vitamin B12 Methylcobalamin - High Strength & Highly Bioavailable Supplement - Vegan & Non-GMO

I became vitamin B deficient due to an illness. Got an actual prescription filled and felt some improvement, with bloodwork showing increased (to normal) range. $4 a month isn’t bad, but knew I could get a better deal on Amazon and found these, which is supposed to be the most available form or vitamin B.The lack of English reviews at the time made me hesitate, and I should have listened. Been taking these for two months now, and I’m feeling worse… With more bloodwork to show I’m deficient again. No idea what these really are, but it’s not doing what the cheap Wallyworld script of B12 was. I’m going back to them.
