Myo & D-Chiro Inositol 40:1 Capsules
DUOZI
with MTHF Folate + Vitamin D3 · Women's Hormonal Balance & Ovarian Support · 2000mg · 60 Capsules
As a leading manufacturer and trusted supplier of premium women's health supplements, we present 40:1 Myo & D-Chiro Inositol Capsules – a science‑backed formula designed to support hormonal balance, ovarian health, and reproductive wellness. This advanced supplement provides the clinically studied 40:1 ratio of myo‑inositol to D‑chiro‑inositol, closely matching the body's natural physiological balance. Each 4‑capsule serving delivers 2000mg of this synergistic inositol blend, enhanced with MTHF Folate (the active, bioavailable form of vitamin B9) and Vitamin D3 for comprehensive reproductive and metabolic support. Inositols play a key role in insulin signalling, follicle maturation, and hormone regulation – making this formula ideal for women seeking to maintain regular menstrual cycles, support ovarian function, and promote a healthy pregnancy environment. With 60 vegetarian capsules per bottle, it provides a convenient 15‑day supply at 4 capsules daily – perfect for consistent daily use.
Scientific evidence supports a 40:1 ratio of myo‑inositol to D‑chiro‑inositol as the most effective for mimicking the body's natural tissue distribution. This balance enhances insulin sensitivity, supports healthy androgen levels, and promotes regular ovulation – making it the gold standard for women's hormonal health.
Inositols are essential for follicle‑stimulating hormone (FSH) signalling and the proper development of ovarian follicles. Our formula helps improve egg quality, supports healthy ovulation, and contributes to a balanced menstrual cycle – crucial for women planning pregnancy or managing cycle irregularities.
We use 5‑methyltetrahydrofolate (MTHF), the biologically active form of folate, which is immediately available for methylation, DNA synthesis, and red blood cell production. It is especially important for women of childbearing age to support proper fetal development during early pregnancy.
Vitamin D3 supports immune function, reduces inflammation, and is linked to improved ovarian reserve and menstrual cyclicity. By including D3, our formula provides holistic support for overall reproductive wellness and metabolic balance.
Each 4‑capsule serving delivers a full 2000mg of the inositol blend, meeting the clinically recommended dosage for hormonal support. The vegetarian capsules are easy to swallow, and the formula is free from artificial additives, gluten, and common allergens.

1. Why is the 40:1 ratio important?
The body naturally maintains a 40:1 ratio of myo‑inositol to D‑chiro‑inositol in tissues. Supplementing with this ratio has been shown in clinical studies to best support insulin sensitivity, hormone regulation, and ovarian follicle maturation – making it the optimal choice for women's hormonal health.
2. Can this supplement help with pregnancy preparation?
Yes. Inositols improve egg quality and ovulation regularity, while MTHF folate is essential for neural tube development. Many healthcare providers recommend inositol and folate for women planning pregnancy, especially those with cycle irregularities or metabolic concerns.
3. Why is MTHF folate used instead of folic acid?
MTHF (5‑methyltetrahydrofolate) is the active, body‑ready form of folate that does not require enzymatic conversion. This is especially important for women with MTHFR genetic variants who cannot efficiently convert folic acid, ensuring they receive immediate nutritional benefit.
4. How long does one bottle last?
Each bottle contains 60 capsules. At the recommended dose of 4 capsules daily, one bottle provides a 15‑day supply. For a full 3‑month course, we recommend ordering multiple bottles for consistent use.
5. Can I take this if I'm not trying to conceive?
Absolutely. This formula supports general hormonal balance, menstrual regularity, and metabolic health, making it beneficial for any woman seeking proactive reproductive and overall wellness support.
6. Can I customize this for my brand?
Yes. We offer full OEM/ODM services – customize the inositol ratio, dosage, capsule size, bottle design, and packaging to create a unique product for your brand.
