About a year ago I had started taking multiple different b vitamin supplements (bottles say hi energy blend, etc) as self treatment trying to have more energy, stamina, etc. i have always thought that any excess B vitamins were simply passed so if too much no big deal, just eliminated anyway but noticed recent blood tests have shown very high levels of B12. No dr as ever commented on it but i asked endocrinologist about high B12 on blood and if i should stop taking the supplements and she said didnt really matter, that basically would just be eliminated. Afterwards, i thought if just eliminated (i assume through urine?) then why would blood test have high level? I decided on my own to cut back the b12 pill to every other day. Any thoughts from the educated greAtly appreciated as this really really is not in my wheelhouse!
