I was diagnosed with PCOS last week. Doctor put me on birth control pills (diane 35) and metformin 1000mg a day for 30 days.

I've been taking L-Carnitine capsules before work out, as it enhance my performance. I also drink protein powder for muscle Recovery and Growth.

My question is, is it safe to take these excerice related supplements while on contarceptive pills and metformin?
