August 13, 2025 2 min read

Resistencia a la insulina, SOP y fertilidad: ¿cómo ayuda el inositol? - Hi Vitamins

Having PCOS is not just about "having cysts". It's a hormonal and metabolic imbalance that can affect your cycle, your ovulation, and your fertility.
If you're struggling to lose weight, have sugar cravings, hair loss, acne, and irregular periods... you're not alone.

The good news is that there is a natural, safe, and scientifically backed supplement that can help you regain your balance: inositol.

What is PCOS and how does it affect fertility?

Polycystic Ovary Syndrome (PCOS) is a hormonal condition that affects 1 in 10 women. The most common symptoms include:

  • Irregular menstruation or absence of period

  • Excess androgens (acne, facial hair, hair loss)

  • Difficulty ovulating

  • Insulin resistance (difficulty processing glucose)

All of this can make it harder to conceive, but it can also improve with the right approach.

What is inositol and how does it work?

Inositol is a type of natural sugar that acts as a messenger in many functions of the body, especially in hormonal and insulin signaling.

The two most studied types for fertility and PCOS are:

  • Myo-inositol

  • D-Chiro inositol

Both work in synergy to:

✅ Improve insulin sensitivity
✅ Reduce androgen levels
✅ Regulate ovulation
✅ Improve ovarian quality
✅ Promote more regular menstrual cycles

What is the best combination?

Clinical evidence suggests that the ideal ratio is 40:1 between Myo-Inositol and D-Chiro Inositol, like the one offered by the Fairhaven Health supplement, available at Hi Vitamins.

This formula respects the body's natural physiological relationship, maximizing benefits and reducing side effects (such as overproduction of androgens or ovarian suppression).

When should you consider taking it?

Inositol can help you if:

  • You have a diagnosis of PCOS

  • Your periods are irregular or absent

  • You have high insulin levels or resistance

  • You are trying to conceive and are not ovulating

  • You are making lifestyle changes and need natural support

How long does it take to take effect?

Most studies show improvements in ovulation, insulin sensitivity, and menstrual regularity after 2 to 3 months of continuous use. The key is daily consistency.

💡 Suggested dosage: 2 capsules a day, with or without food.

 Can it be combined with other supplements?

Yes. The Myo + D-Chiro Inositol can be safely combined with:

  • OvaBoost, if you are also looking to improve ovarian quality

  • Prenatal multivitamin with active folate, if you are trying to conceive

  • FertilAid for Men, if you are on a joint plan with your partner


Inositol is not a trend or a magic solution, but it is a powerful and safe tool for many women with PCOS or hormonal imbalances.
By supporting your metabolism and ovulation, it helps you reconnect with your body and fertility from a real place, without forcing or invading it.
