Does inositol affect the menstrual cycle?

Inositol can affect the menstrual cycle, especially in women with hormonal imbalances such as polycystic ovary syndrome (PCOS).

Inositol is a naturally occurring substance related to B vitamins. It plays a role in insulin sensitivity, hormonal balance, and cell communication.

Women with PCOS often have insulin resistance, which leads to elevated insulin levels. This can disrupt the balance of sex hormones, causing ovulation to fail and menstrual cycles to become irregular. Myo-inositol improves insulin sensitivity, which indirectly normalizes estrogen, LH, and FSH production and restores menstrual cycles.

Research shows that inositol can stimulate ovulation, especially in women with PCOS who otherwise ovulate irregularly or not at all. It can help to make the cycle more regular and increase the chance of natural pregnancy.

PCOS patients often have elevated androgens (male hormones), leading to symptoms such as acne, excess hair, and irregular cycles. D-chiro-inositol helps lower testosterone levels and restore balance to female hormones.

Inositol can have a positive effect on the menstrual cycle, especially in women with PCOS and insulin resistance. It can stimulate ovulation, improve insulin sensitivity, and restore hormonal balance. It is wise to consult a doctor before considering inositol.
