Myo-Inositol

A key nutrient that supports healthy insulin response, hormonal balance, and female reproductive health.

What it is

Myo-Inositol is a naturally occurring nutrient related to the B-vitamin family (formerly called Vitamin B8). It plays an essential role inside your cells as a helper for insulin and reproductive hormones.

In female health, myo-inositol helps your body manage insulin properly, supports regular ovulation, and promotes healthy hormone balance.

Also known as: Inositol, Vitamin B8, cis-1,2,3,5-trans-4,6-cyclohexanehexol

Key benefits

  • Helps your cells respond properly to insulin, so your body manages sugar and energy efficiently.
  • Supports regular ovulation and egg quality, which promotes healthy female fertility.
  • Helps balance male-type hormones hormone levels, supporting clearer skin and hormonal harmony.

Amplified by probiotics

Myo-Inositol is absorbed through specific carriers in your small intestine. When your gut lining is inflamed, nutrient absorption slows down. Microencapsulated probiotic strains strengthen the gut barrier and reduce gut inflammation. By maintaining a healthy, leak-free gut, probiotics support efficient myo-inositol absorption, working together to promote healthy how well your body responds to insulin and hormonal balance.

Typical dose

2,000–4,000 mg/day
