It could bc doesn't met work by lowering IR?

Yes it does. So I'm assuming it would have to work similarly. Just wondering if lowering it naturally is more effective.

My sister is taking Metformin for her PCOS and honestly, it doesn't seem to be doing much for her. She does not really eat healthy at all, or balanced (ramen noodles, pizza, bagels, carbs carbs carbs) so that probably is another reason. She doesn't have problems with acne, but she is overweight and has eczema.

Personally, I would ditch the Metformin and choose some healthy, natural alternatives to control blood sugar. I have read that some people drink apple cider vinegar in replace of Metformin. I drink it every day. And, of course, a low GI diet is a must if you have blood sugar issues. Sweet potatoes are a good substitute for those staple carbs.

Plus, with a healthy diet, you'll get loads more benefits and none of the side effects.

Also, for your PCOS, have you heard of drinking mint tea? It might work, unless you have estrogen dominance. It inhibits the enzyme, 5-alpha reductase which converts hormones to DHT. If you do consider it, just drink it during your follicular phase (the first half of your cycle), otherwise it can cause irregularity.

Yes. Its better in fact. Eat real, whole nutrient dense food.
