Fertility Hero Pure Myo-Inositol

PMOS stands for Polycystic Metabolic Ovarian Syndrome, the updated name for what has historically been called PCOS (Polycystic Ovary Syndrome).

You’ll still see PCOS used widely — particularly in published research — while the newer terminology becomes established. If you have previously been diagnosed with PCOS, PMOS refers to the same condition.

Myo-inositol is a naturally occurring compound found in the body and in foods including fruits, beans and grains. It is involved in cell signalling, including pathways involved in the body’s response to insulin.

It has been extensively studied in women with PMOS (formerly PCOS), as well as in metabolic and reproductive health more broadly.

We provide 4g of myo-inositol per day, a dose used extensively in clinical research and particularly common in studies involving women with PMOS.

It’s an evidence-based choice: we wanted the amount in our product to reflect the clinical literature rather than simply using a smaller dose to reduce the number of capsules.

Your daily 4g is divided into two 2g doses, which reflects the dosing schedule used in many clinical studies of myo-inositol.

Take three capsules twice daily with food — for example, once in the morning and once in the evening.

Some supplements combine myo-inositol with D-chiro-inositol, commonly in a 40:1 ratio. Both forms occur naturally in the body and have been studied in PMOS.

We chose to keep our formulation focused on pure myo-inositol at 4g per day, because myo-inositol alone has a substantial clinical research base and the evidence has not established that a combined 40:1 formulation is superior.

It also means you know exactly what you're getting: one active ingredient at a clinically studied dose.

No. Although much of the research has focused on women with PMOS and insulin resistance, myo-inositol has also been studied in other populations.

That includes women undergoing IVF without PMOS, as well as research into male reproductive and wider metabolic health.

Myo-inositol has been studied in women undergoing assisted reproduction, including women both with and without PMOS.

Research has explored outcomes including ovarian stimulation and oocyte maturity, although results vary between studies. If you’re undergoing fertility treatment, you can also discuss any supplements you’re taking with your clinic.

Yes. Myo-inositol isn’t included in Fundamental Woman, so there is no duplication.

It can also be taken alongside our CoQ10, Omega-3 and magnesium products as part of your wider preconception routine.

Just two: myo-inositol and the plant-based HPMC capsule shell.

There’s no magnesium stearate, silicon dioxide or other added fillers or excipients.

With a 180-capsule product, we wanted to avoid a large plastic container. Our pouch is made from a plastic-free compostable laminate, reducing both plastic waste and unnecessary exposure to plastic in the packaging of a product you take every day.

It’s suitable for home composting depending on local conditions and facilities.

Yes. The myo-inositol is not animal-derived and the capsule is made from plant-based HPMC.

Myo-inositol has also been studied in male reproductive health, including research looking at sperm motility and DNA fragmentation.

The evidence in men is less established than the research in women, but it’s an interesting and growing area. Myo-inositol can be taken alongside Fundamental Man and CoQ10.
