Top reviews from the United States

  • Worked great for hirsutism, hormonal acne, insomnia

    This stuff surprised me. Not diagnosed with PCOS, but developed symptoms related to insulin resistance and high androgen levels, many of which overlapped with PCOS, so I gave this a try.

  • Pcos girlies, TRY THIS!!

    2.5 weeks after starting it, I OVULATED. I am still shocked. After four months of no ovulation, I was semi-convinced I was going into menopause. I have felt great, and can't wait to get my follow-up bloodwork to confirm ovulation, but my LH levels were the highest I have EVER had.

  •  Weird reaction initially, but now I love it.

    This is the highest quality inositol supplement, and cannot recommend it enough. If you are on the fence, TRY IT. If you are on a different inositol and are hesitant to switch to ovasitol because of the price point, make the switch. It is so worth it. I wish I could rate this 10 stars!!!
