I take yaz (drospirenone and ethinyl estradiol) bcp. i want to start taking apple cider vinegar+nettle+chromium pills as a dietary supplement for aided weight loss. will they interfere?

There's no easy fix: Weight loss is a difficult challenge-and any supplements or pills are unlikely to have a real effect. (Of course there are stimulants that increase your metabolic rate-but these are a bit dangerous since there could be side effects with those). I don't think this supplement you've mentioned will have an effect, so I wouldn't waste money on it. EXERCISE and eating right are much better alternatives
