Inositol vs Berberine

Diagnosed with insulin resistance and i also have high testosterone. My periods arrive consistently, but they are very heavy and last about 7-8 days.

I recently started taking Pilates reformer classes 3x a week, and plan to walk more. Slowly reducing carbs/sugars, drinking more water, and more greens in my diet.

Would Inositol or Berberine be the better option for me? My doctor wanted me to take Metformin, but i refuse to take any medications (prefer a holistic lifestyle).

I plan to discuss both options with my doctor, but i wanted to get Reddit’s experience on these 2 supplements and which would be ideal for me.

Appreciate any help!
