supplement overdose???

I am 6 months out from RNY and am still very tired.  I have started increasing my supplements and I never considered that taking too many might be harmful.  I take: morning:  1 multi vitamin                    1 hair, nails & skin vitamin                    2 B-12 sublingil                    2 calcium (400 ea) afternoon:  2 B-12                     2 calcium evening:  1 iron (29)                   2 vitamin C (500ea)                   1 Zinc                   1 B-100 In addition to my protein This is alot but I am definetely feeling better.

I don't see any glaring problems. You have 1600 mg Calcium I don't know the dosage on the B12 - but it is poorly absorbed so more is ok I don't know what's in your Hair & nails - probably biotin and B-vits. You are taking a big dose of vitamin C all at once.  It is better to disperse vit C throughout the day.  Even in a normal GI tract, the body can only absorb about 65-100 mg at a time.  A smaller amount multiple times a day (100 mg chewable, for instance) Hope this helps!
