For instance, Viatmin A and E are easily available from our daily food and being fat soluble, they get stored in our tissues
and overdosing is very easy. I do not know, why
the Companies are packing such easily availble vitamins along with some other difficult to get nutrients like zinc, omega3 or B12. So, while taking supplements, always do consult the doctor. Alternatively, get the vitamins and nutrients from the dialy food or natural inputs, for example, wheat grass, etc.
