[RC] yucca extract

[Maggie Mieske]

Hi folks, Question about that yucca extract stuff.  I think I have read that it will test positive.  I have found a supplement I might like to try but it also has 375 mg. of yucca extract in the daily dose.  Of course, I don't want to feed my horse a supplement that could cause a positive test.  Would discontinuing the supp a few days before a ride prevent that?  It's basically a joint/hoof/vitamin/probiotic kind of supplement.  But I am concerned about the yucca.  Any advice would be appreciated.  Thanks.
