Players on the women's tour have been given the green light to take certain health supplements without the fear of failing a drugs test.
This week, governing body WTA signed an agreement that will provide competitors with products that are guaranteed to be free of any substances prohibited by WADA.
Products from USANA Health Sciences Inc., a leading global vitamin and health supplement manufacturer, will help ensure that players who wish to take vitamins and supplements are able to maintain fitness without fear of violating the rigorous WADA standards.
Each player in the programme will be eligible to sign an "athlete guarantee agreement" with USANA under which the manufacturer will pay the player twice her prize-money earnings from the prior year should the player test positive for a prohibited substance.
