Just looked into inositol and am floored it has never been recommended to me. Does anyone have brand recommendations?

I have bipolar 2 and was recently diagnosed with PCOS. My family has a history of insulin resistance. I have been struggling with my weight for years- I have had binge eating disorder and body dysmorphia since I was a child, but was never overweight. Then after my bipolar diagnosis I was put on abilifi and suddenly gained 60 pounds. My mom pushed me to go on Atkins and I did the yo-yo diet thing for a couple of years, which destroyed my metabolism and left me very overweight and feeling very ill… quarantine also did me really dirty. Anyway, I’m on Metformin now, which has helped some, but I’m having trouble losing more that the ~20 pounds I’ve lost so far.

I appreciate any recommendations given my situation.
