I tried pure b12 from https://www.sunday.de/ it contains destilled water, alchole and vitamin 12. I tried the eye route it hurts like hell for a few seconds , not sure if it works or not but i've tried to place the dropplets in the eye every possible way (corner of eye, in the iris, on the pupil, lifting bottom eyelid down and pour in there) and maybe i felt something initially but now nothing. Does b12 need other vitamins to work properly ? perhaps because im deficient in other b vitamins its not working as it should. Or im not leaving the b12 on my eye long enough? When it hits my eye I have no choice but to close my eye so it doesnt hurt and somehow it stops it but not sure if that makes the b12 spill out or get moved deeper in the eye. Either way im prepared to lose one eye doing this lol.
@fishboy9320 please re-think about putting anything containing alcohol into your eye. It really isn't worth it. A badly damaged eye will just add to your woes. Alcohol does not go well applied to sensitive mucus membranes.
wow sorry about my previous stupid posts I feel embarrassed by them now. But do all the B vitamins need each other to work effectively? Like how useful is b12 if you are deficient in folate? And vice versa. Are there any infos on this?
