Inositol and Natural Ovulation in Polycystic Ovary Syndrome (PCOS)

Hello, Doctor.
I hope you can provide advice and clarification based on my situation.
Thank you!
Background: I am 23 years old.
Six years ago, I was overweight with a fasting blood sugar of 133 mg/dL.
Since then, I have experienced irregular menstrual cycles, with periods occurring about every six months and lasting over ten days.
After 2-3 years, I gradually returned to a normal weight, and my menstrual cycle improved but remained irregular.
An ultrasound revealed that I have polycystic ovaries in both ovaries.
Following my doctor's advice, I took birth control pills for a year and a half, but I have stopped taking them.

In February of this year, my blood test results were mostly normal: fasting blood sugar 82, postprandial blood sugar 107, hemoglobin A1c 5.1, testosterone 17 ng/dL, and normal levels of estradiol (E2), follicle-stimulating hormone (FSH), and luteinizing hormone (LH).
However, my prolactin level was slightly elevated at 32 ng/mL.

I would like to ask:
1.
I do not plan to get pregnant at the moment, but I hope to help my ovaries ovulate naturally to improve my irregular menstrual cycles.
Would taking inositol be beneficial? (Since the birth control pills caused anovulatory cycles, I want to see if I can fundamentally address the "anovulation" issue.)
2.
I found that the recommended daily dosage of inositol for polycystic ovary syndrome (PCOS) is up to 2g.
However, my diet is currently balanced and healthy, and my blood test results are mostly normal.
If I were to take inositol, what daily dosage would you recommend?
3.
If I take inositol, how long should I continue? What would happen if I stopped taking it?

More Info

Inositol has gained attention as a potential supplement for women with Polycystic Ovary Syndrome (PCOS), particularly for those looking to improve their ovulatory function and regulate menstrual cycles. Based on your background and current situation, let’s address your questions regarding the use of inositol for natural ovulation.

1. Can inositol help with natural ovulation?
Yes, inositol, particularly in the form of myo-inositol, has been shown to have beneficial effects on ovarian function in women with PCOS. It plays a role in insulin signaling and can help improve insulin sensitivity, which is often impaired in women with PCOS. Improved insulin sensitivity can lead to better hormonal balance and may promote regular ovulation. Since you are not currently trying to conceive but wish to regulate your menstrual cycle, inositol could be a helpful addition to your regimen. It may assist in restoring more regular ovulatory cycles, especially after a period of hormonal imbalance caused by the use of contraceptive pills.

2. What is the recommended dosage of inositol?
The typical dosage of inositol for women with PCOS ranges from 2 grams to 4 grams per day. Since you mentioned that your diet is balanced and your blood test results are mostly normal, starting with a lower dose, such as 2 grams per day, could be a prudent approach. This allows you to monitor how your body responds to the supplement without overwhelming it. If you find that you tolerate it well and wish to see more pronounced effects, you could consider gradually increasing the dosage to 4 grams per day.

3. How long should I take inositol, and what happens if I stop?
The duration of inositol supplementation can vary based on individual responses and goals. Many studies have used inositol for at least 3 to 6 months to assess its effectiveness in improving ovulatory function and metabolic parameters. If you decide to start taking inositol, it would be reasonable to commit to at least this duration to evaluate its impact on your menstrual regularity and overall hormonal balance. If you stop taking inositol, the effects may gradually diminish, particularly if your underlying insulin sensitivity issues or hormonal imbalances are not addressed through other lifestyle changes, such as diet and exercise. It’s important to remember that while inositol can be beneficial, it should be part of a comprehensive approach that includes maintaining a healthy weight, regular physical activity, and a balanced diet.

In conclusion, inositol may be a beneficial supplement for you as you work towards regulating your menstrual cycle and improving ovulatory function. It’s always advisable to discuss any new supplement with your healthcare provider, especially considering your unique health history and current conditions. They can provide personalized recommendations and monitor your progress effectively.
