Does bcaa and/or amino acids effect birth control pills? specific i'm taking the shredz brand bcaa powder.

Birth Control: unless there is some estrogen or progesterone in the powder it is doubtful. However, I doubt there have been specific testing done to see if there is any interactions. The FDA which controls the medications in the US has no control of supplements. They are classified as foods and don't have to meet drug standards for testing. They just put the warning that they make no claim to treat or cure.
