Each day I take a multi-vitamin and a cod liver oil tablet (along with creatine and L-Glutamine). Both of these tablets claim to contain 100% RDA (Recommended Daily Amount) of Vitamin A. I take these last thing at night (except the creatine which is before/after workout).
I believe that too much Vitamin A is not good for you, and going above the RDA by twice as much of anything probably isn't a good idea. But there is no way to avoid it as both capsules have 100% RDA.
Am I risking damaging my kidneys by giving them too much Vitamin A to process in one go? Should I take the cod liver oil in the morning, and the multivitamin in the evening? Or vice-versa?
