I really want to take a sun tanning supplement but I'm not sure which is a good one to try. I have done some research and so far I have found that there are basically two types of supplements....one's with a substance called "Canthaxanthin" and those without this substance. I was just wondering if anyone had ever taken any a tanning supplement that they found to be very good or have any information about the pros and cons of Canthaxanthin. If anyone has any information or advice whatsoever, I would be very very greatful :) Thankyou very much!!!!!!!
