everything about vitamins

Vitamin A is needed for many functions of our body, especially for healthy skin and eyes. Together with zinc, it is necessary for cancer prevention and healing, and for generative glands (gonads) functionality. Itching skin is one of the symptoms of its absence, which in further stage can also cause problems with menstruation for women and with fertility for men.

It is said that surplus of vitamin A is toxic, yet that is only a theory and there is no known case of problems coming from vitamin A overdosage.

I have decided to start an active promotion of this website, so that we get more visitors soon. And it would be a waste of time if we didn't allow for discussion and sharing of informations. In light of that, discussion forum will be officially launched on June 21st.



I hope it will serve a positive function in opening alternative horizons in the area of general information about vitamins.
