yep you can get Vitamin A at most good pharmacies and also over the internet. I wouldn't recommend Retinol though. Go for one of the Retinol Esthers instead, like: Retinyl Acetate or Retinyl Palmitate. Also don't get confused with Beta Carotene as this has not been converted into Vitamin A by the body yet (Liver to be exact)...You could also consider fish liver oils as these contain actual Vitamin A and D, but they tend to be rather stinky and non standardised. In other words its difficult to know how much you are getting. Hope that helps....Good luck
