What Is The Maximum Dosage Of Vitamin A And E Per Day?

Hi,

I am sickle cell trait and have G6PD defeciency. My Hb-S is around 25 to 30 %. I take folic acid 5 mg OD, Multivitamins 1 tab OD, and 1 capsule of cod liver oil ( 7 seas ) at bed time.

The dose of of vitamin A in multivitamins is 3333 IU.

The dose of of vitamin A cod liver oil is 200 mcg.

Questions:

1- Is it safe to take these three medications per day at a time ?

2- what is the maximum dose of vitamin A and vitamin E per day ?

3- Is hypervitaminosis A a risk here ?

thanks
