Myo Inositol Capsules

Myo inositol is one of nature's most researched compounds for women's hormonal health, and Naturecan's Myo Inositol Capsules deliver a clean, concentrated 1,000mg dose in every capsule. If you're navigating irregular cycles, or hormonal imbalance, this is a research-backed, single-ingredient supplement built for precision: pure myo-inositol, encapsulated in a vegan HPMC shell, with no unnecessary additives, fillers, or binders. Explore our guide to the best supplements for hormonal health to understand how myo-inositol fits within a broader hormonal support plan. 60 capsules. 60 days. One ingredient. Complete clarity.

Why Choose Myo Inositol

Myo inositol is involved in the signalling pathways your body uses to regulate insulin and communicate between cells [1]. Yet most inositol products on the market come loaded with unnecessary co-ingredients, unclear dosing, or proprietary blends that make it impossible to know exactly what you're getting. Naturecan keeps it simple: 1,000mg of pure myo-inositol per capsule, encapsulated in a vegan HPMC shell, free from gelatin, binders, and bulking agents.

The key differentiator is clarity. A 60-capsule pack provides a full 60-day supply at the standard daily dose, so you know exactly what you're taking, how much, and why. This is a supplement built for long-term use, not short-term promises.

Key Benefits of Myo Inositol

Myo-Inositol and Insulin Signalling Research

Myo-inositol is thought to act as a secondary messenger in the insulin signalling cascade. Research suggests that supplementation may support healthy insulin sensitivity, particularly in women with PCOS [1]. As a precisely dosed inositol supplement delivering a full 1,000mg per capsule, Naturecan's formula provides a consistent daily amount to support this pathway.

Myo-Inositol and Hormonal Health Research 

A substantial body of evidence examines the inositol benefits for women's hormonal health. Studies suggest that myo-inositol supplementation may be associated with reductions in elevated luteinising hormone (LH) and androgen levels frequently observed in women with hormonal imbalance [1]. These changes may be linked to improvements in ovarian function over the course of consistent supplementation.

Myo-Inositol and Menstrual Cycle Research 

Clinical research indicates that myo-inositol may support more regular menstrual cycles in women experiencing irregularity associated with hormonal imbalance [3]. In research settings, measurable changes have been observed after eight to twelve weeks of consistent supplementation, making this a supplement best adopted as part of a longer-term routine.

Myo-Inositol and Metabolic Health Research 

Beyond hormonal support, researchers have also explored inositol weight loss associations in the context of metabolic health. Some evidence suggests that the improvements in insulin signalling associated with myo-inositol supplementation may be linked to more balanced energy metabolism and body composition outcomes in women with PCOS [4]. If you are also exploring approaches to support healthy blood sugar and metabolic function, see our natural ozempic alternatives guide for broader context.

Premium Quality, Independently Tested

Every batch of Naturecan Myo Inositol Capsules is independently tested for purity and potency before it reaches you. No unnecessary ingredients dilute the formula, and every batch is produced under Good Manufacturing Practice (GMP) standards. What you see on the label is exactly what is in your capsule. 

What's Inside Myo Inositol

Key Active Ingredients

Each capsule delivers 1,000mg of myo-inositol, a naturally occurring compound from the B-vitamin family found in foods including fruit, beans, grains, and nuts. In supplemental form, it provides a concentrated dose that is difficult to achieve through diet alone [4]. The formula is intentionally minimal: myo-inositol as the sole active ingredient, with a hydroxypropyl methylcellulose (HPMC) capsule shell as the only excipient.

Ingredient Quality, Sourcing, and Bioavailability

Myo-inositol is water-soluble and generally well absorbed when taken orally. The capsule format supports consistent, precise dosing without the flavours, sweeteners, or flow agents commonly found in powder formats that can compromise formula purity.

How to Take Myo Inositol

Recommended Daily Dosage

Take one capsule (1,000mg myo-inositol) per day. This aligns with the lower end of doses used in peer-reviewed research; clinical studies have investigated doses ranging from 1,000mg to 4,000mg daily, often split into two servings [1]. If you are considering a higher dose for a specific health goal, consult a registered healthcare professional before adjusting your intake.

When to Take It

A myo inositol supplement can be taken at any time of day, with or without food. Many people find it easiest to take it alongside another daily supplement or as part of a consistent morning routine. Taking it at the same time each day supports habit formation, which is one of the most reliable predictors of supplementation success.

What to Expect in the First 4-6 Weeks

Myo-inositol is not a fast-acting supplement. In research settings, measurable changes in hormonal and metabolic markers have been observed after eight to twelve weeks of consistent use [3]. During the first four to six weeks, focus on establishing a daily habit and allowing the compound time to build in your system. Avoid discontinuing early on the basis of an absence of immediate results.

Can I Combine This With Other Supplements?

Myo-inositol is commonly used alongside other supplements that support women's hormonal and metabolic health. Research specifically examining the combination of myo-inositol and D-chiro-inositol has proposed a 40:1 ratio as physiologically relevant in the context of ovarian function research [5]. Myo-inositol also pairs naturally with vitamin D, zinc and magnesium, and berberine. If you are taking any prescription medications, particularly those affecting blood sugar or hormonal function, consult your doctor or pharmacist before adding any new supplement.

The Science Behind Myo Inositol

What Peer-Reviewed Research Shows

A systematic review published in Gynecological Endocrinology assessed evidence from multiple randomised controlled trials examining myo-inositol supplementation in women with PCOS [1]. The review reported associations between supplementation and ovarian function, menstrual cycle patterns, and insulin sensitivity markers, as well as androgen levels, in study participants. A meta-analysis published in BJOG: An International Journal of Obstetrics and Gynaecology examined inositol supplementation and ovulation rates in research participants compared to controls [6].

Key Clinical Study Highlights

A frequently cited study published in the New England Journal of Medicine examined the effects of D-chiro-inositol on insulin sensitivity and androgen levels in women with PCOS, reporting statistically significant improvements in both measures [2]. While D-chiro-inositol and myo-inositol perform different roles within the inositol phosphoglycan signalling system, they are increasingly studied in combination, with evidence suggesting that combined use may produce complementary effects [5]. For those researching the best inositol supplement for their specific needs, understanding this distinction is an important part of making an informed decision.
