I bought a 1000mcg b12 and I was wrong my b complex has only 15mcg. I also take a vitamin one a day women tht has 6mcg. Now I think like I said I have high b12 unless I was mistaken but like I said was told to take a break from the b complex for a week but my symptoms are getting worse since stopped unless a fluke.I have the other leg and now my arm is numb a little tender but not the pain as in leg. So if not an issue with too high b12. Do I take the 1000mcg of b12 plus the others or just that? What would you do?
