PMOS (PCOS) Support
PMOS Fertility Support · Formerly Known As PCOS
PMOS is the new name for PCOS. Our fertility support stays just as personal.
PMOS stands for Polyendocrine Metabolic Ovarian Syndrome, the updated clinical term for the condition most people still know as PCOS. It is not a new or separate condition, just a name change that better reflects the hormonal and metabolic factors involved.
Whether you know it as PMOS or PCOS, our nutritionists understand how it can affect ovulation, hormone balance and your wider fertility journey. We offer personalised nutrition guidance and targeted supplements designed to support your hormones and cycle health, alongside expert advice tailored to you.
Nutrition and supplements are intended to support overall hormonal and reproductive wellbeing as part of a wider lifestyle approach. They are not a treatment, cure or guarantee of ovulation or pregnancy.
Fertility Nutrition · PMOS
Can supplements support fertility with PMOS?
Supplements cannot treat or cure PMOS, but specific nutrients may help support areas that matter when trying to conceive, including ovulation, insulin sensitivity, hormone balance, egg health and inflammation.
Nutrition, lifestyle and targeted supplementation are commonly considered to work best together, alongside personalised guidance from a nutritionist who understands your individual hormone profile, cycle and goals. This is especially important if you are taking medication or currently undergoing fertility treatment, as your plan should be tailored to you.
PMOS and PCOS refer to the same condition. Supplements play a supporting role within a wider approach and do not guarantee ovulation, fertility or pregnancy.
PMOS / PCOS is one part of female fertility foundations, alongside ovulation, egg quality, AMH, endometriosis, nutrition and lifestyle.

What is PMOS?
PMOS stands for Polyendocrine Metabolic Ovarian Syndrome. It is the newer consensus name for PCOS, previously known as Polycystic Ovary Syndrome. PMOS and PCOS refer to the same condition, not two different ones.
The name has changed because PCOS placed a lot of emphasis on ovarian cysts, even though not everyone with the condition has cysts. PMOS better reflects the wider hormonal, metabolic and ovarian features involved, rather than focusing on one physical sign.
PMOS can involve hormone imbalance, insulin resistance, irregular ovulation, changes in androgen levels and wider metabolic health. How it shows up varies from person to person, which is why personalised support is often helpful rather than a one size fits all approach.
Throughout this page, we use PMOS as the newer term while also referencing PCOS, since many people still know and search for the condition by its former name.
PMOS means
- PolyendocrineInvolving multiple hormone systems, not just one
- MetabolicLinked with insulin sensitivity and wider metabolic health
- OvarianInvolving ovarian function and ovulation
- SyndromeA group of related signs and symptoms, which can vary from person to person
PMOS and fertility
How can PMOS affect fertility?
PMOS can affect fertility because it may influence ovulation, cycle regularity, hormone balance and metabolic health. Some women with PMOS ovulate less regularly, which can make it harder to predict fertile days and may increase the time it takes to conceive. This does not mean everyone with PMOS finds it hard to conceive, as the condition and its impact vary from person to person.
PMOS is also commonly associated with insulin resistance. In simple terms, this means the body may find it harder to use insulin effectively, which can affect blood sugar balance, hormone signalling and ovarian function.
Changes in androgen levels can also play a role. Higher androgen levels may contribute to irregular cycles, skin changes, excess hair growth and disrupted ovulation in some women, though not everyone experiences this in the same way.
In simple terms, PMOS may affect fertility by disrupting ovulation, influencing insulin sensitivity and changing hormone signalling. Supporting metabolic health, cycle regularity and nutritional status can be an important part of preparing for pregnancy.
PMOS can look different from person to person, so the most helpful fertility support plan will depend on your symptoms, cycle pattern, health history, nutrition, lifestyle and any treatment you are already undergoing. Personalised guidance is often the best starting point.

Nutrition and supplements
What supplements are commonly used for PMOS fertility support?
Several nutrients are commonly considered in fertility nutrition plans for PMOS. Supplements cannot treat or cure PMOS, but they may help support areas that matter when trying to conceive, including ovulation, insulin sensitivity, hormone balance, egg health, inflammation, gut health and preconception nutritional status.
The Zita West PMOS (PCOS) Support Pack is designed to provide targeted nutritional support for women managing PMOS.
In PMOS fertility nutrition, supplements are usually used to support specific areas such as insulin sensitivity, ovarian function, hormone balance, antioxidant status, gut health and overall preconception wellbeing, rather than to treat the condition itself.
What is included in the PMOS (PCOS) Support Pack?
The Zita West PMOS (PCOS) Support Pack contains seven key supplements selected to support reproductive, hormonal, metabolic and gut health.
The seven supplements in the pack
Inositol & Folate
Myo-inositol is commonly considered in PMOS fertility nutrition because it may help support insulin sensitivity and ovarian function. Folate is also important before and during early pregnancy and contributes to maternal tissue growth.
Vitamin D
Vitamin D supports immune function, hormone health and healthy cell division. Low vitamin D levels are commonly discussed in relation to PMOS, particularly when preparing for pregnancy.
N-Acetyl Cysteine
N-Acetyl Cysteine, also known as NAC, is a precursor to glutathione, one of the body's key antioxidants. It may help support antioxidant status, cellular defence, metabolic wellbeing and ovulatory health.
Vitafem
Vitafem is a fertility focused multivitamin and mineral formulation designed to provide daily nutritional support, including nutrients relevant to hormone metabolism, egg health and preconception wellbeing.
Ultra Omega
Ultra Omega provides essential omega 3 fatty acids, which may help support normal inflammatory balance, cell structure, hormone pathways and wider reproductive wellbeing.
Femceive
Femceive is a fertility friendly bacteria supplement designed to support the gut and vaginal microbiome, both of which may be relevant to immune function, hormonal wellbeing and preconception preparation.
Psyllium Husk Capsules
Psyllium husk is a gentle source of fibre that can help support digestive health, gut function and blood sugar balance as part of a broader PMOS nutrition plan.
Can the supplements in the PMOS (PCOS) Support Pack be taken together?
Yes. The PMOS (PCOS) Support Pack has been curated as a combined routine, with each product selected to support a different nutritional area. If you take prescribed medication, are undergoing fertility treatment or are considering extra supplements alongside the pack, speak to your clinic, doctor or a Zita West nutritionist first.
The most appropriate supplement routine will depend on your symptoms, cycle pattern, diet, medication, health history and whether you are preparing for or undergoing fertility treatment.
If you are taking medication, managing complex symptoms or undergoing fertility treatment, speak to your doctor, fertility clinic or healthcare professional before starting new supplements.

Frequently asked questions about PMOS, PCOS and fertility support
Is PCOS now called PMOS?
Yes, PMOS is the newer consensus name for PCOS. PMOS stands for Polyendocrine Metabolic Ovarian Syndrome and better reflects the endocrine, metabolic and ovarian features of the condition. Many people still know and search for it as PCOS, so both terms are often used during the transition.
Why was PCOS renamed PMOS?
PCOS was renamed PMOS because the older name focused heavily on ovarian cysts, even though not everyone with the condition has cysts. PMOS better reflects the wider endocrine, metabolic and ovarian features of the condition, including hormone balance, insulin sensitivity and ovulation.
What does PMOS stand for?
PMOS stands for Polyendocrine Metabolic Ovarian Syndrome. Polyendocrine refers to multiple hormone systems, metabolic reflects areas such as insulin sensitivity, and ovarian recognises the role of ovarian function and ovulation.
What is the difference between PMOS and PCOS?
PMOS and PCOS refer to the same condition. PCOS, or Polycystic Ovary Syndrome, was the older name, but it over-emphasised ovarian cysts. PMOS is the newer name and better reflects the wider hormone, metabolic and ovarian features involved.
Can PMOS affect fertility?
PMOS can affect fertility because it may influence ovulation, cycle regularity, hormone balance and insulin sensitivity. Some women ovulate less regularly, which can make it harder to predict fertile days. Many women with PMOS can still conceive, especially with the right support and guidance.
Can supplements support fertility with PMOS?
Supplements cannot treat or cure PMOS, but specific nutrients may help support areas that matter when trying to conceive, including ovulation, insulin sensitivity, hormone balance, egg health and inflammation. They work best alongside nutrition, lifestyle and personalised guidance.
Is inositol useful for PMOS or PCOS fertility support?
Myo-inositol is commonly considered in fertility nutrition for PMOS, formerly PCOS, because it may help support insulin sensitivity and ovarian function. It is often included in preconception plans for women with irregular cycles or signs of insulin resistance.
What is included in the Zita West PMOS (PCOS) Support Pack?
The Zita West PMOS (PCOS) Support Pack contains seven key supplements: Vitamin D, N-Acetyl Cysteine, Vitafem, Femceive, Psyllium Husk Capsules, Inositol & Folate and Ultra Omega. The pack is designed to support nutritional areas relevant to PMOS, formerly PCOS.
Can I take the PMOS (PCOS) Support Pack if I am having fertility treatment?
If you are having fertility treatment, speak to your fertility clinic, doctor or healthcare professional before starting the PMOS (PCOS) Support Pack or any new supplement routine. This is especially important if you are taking medication or following a specific treatment plan.
How long should I take fertility supplements before trying to conceive?
Many people begin fertility supplements around three months before trying to conceive, because egg development and nutritional status take time to support. However, the right timing depends on your health, cycle pattern, diet, treatment plans and individual needs.
Where should I start if I have PMOS and want to get pregnant?
A good place to start is with personalised fertility nutrition guidance, especially if you are unsure which supplements are suitable. Zita West offers free 1:1 product consultations to help you understand your options and choose a supportive next step.
