If you've been researching supplements for hormonal or metabolic health, you've probably come across inositol, alpha-lipoic acid, and magnesium – often in the same breath. There's a reason for that. These nutrients play well-documented roles in supporting female reproductive health, healthy glucose metabolism, and hormonal balance.
The Nutrients that Matter for Female Hormonal and Metabolic Health
Inositol – And Why the Ratio Matters
Inositol is a naturally occurring compound found in many foods and produced by the body. Two forms – myo-inositol and D-chiro-inositol – are particularly relevant to female reproductive and metabolic health and have been studied extensively in the context of both hormonal balance and normal ovarian function [1].
Inositol plays an important role in insulin signalling pathways and ovarian function, making it a key nutrient for supporting metabolic balance and normal reproductive processes [7].
Research on women's hormonal health has frequently used a 40:1 ratio of myo-inositol to D-chiro-inositol – a proportion that reflects the naturally occurring ratio found in the body's tissues [1].
A recent study from Gynecologic and Obstetric Investigation followed 34 women with a specific PCOS phenotype for three months, giving them a daily inositol supplement combining myo-inositol and D-chiro-inositol in a 40:1 ratio. Over half the women were overweight or obese, and half had insulin resistance at the start. By the end of the study, BMI and insulin resistance markers had both improved significantly, along with fewer women showing elevated insulin levels. Hormone levels shifted too – testosterone and LH went down, while SHBG (Sex hormone-binding globulin) and oestradiol went up [1]. Read more on inositol here.
Alpha-Lipoic Acid – Metabolic Support that Goes Beyond Inositol
Alpha-lipoic acid (ALA) is a naturally occurring compound with antioxidant properties and contributes to macronutrient metabolism and the maintenance of normal blood glucose levels. It has been clinically proven to improve insulin sensitivity and blood glucose levels in PCOS patients [2].
A 2020 study from International Journal of Endocrinology looked at how alpha-lipoic acid (ALA), combined with myo-inositol (MI), affected women with polycystic ovary syndrome (PCOS). Researchers followed 71 women for six months. Everyone took 800mg of ALA a day, split into two groups: one group also took 2000mg of MI, the other 1000mg [8].
The results: cycle regularity improved in around 71% of women overall, whether or not they had insulin resistance. Women with insulin resistance saw the biggest changes in their metabolic markers, while women without it saw bigger shifts in their reproductive hormones [8].
Chromium – Supporting Normal Blood Glucose Levels
Chromium is a trace mineral that contributes to the metabolism of macronutrients and the maintenance of normal blood glucose levels [3]. Chromium provides a well-evidenced foundation for glucose regulation and insulin function support [3].
A study from Diabetes Technology & Therapeutics looked at chromium picolinate (CrPic), a commonly used supplement, and its role in blood sugar control. Reviewing 15 clinical studies with over 1,600 participants, researchers found that most trials showed measurable benefits for participants – including improvements in blood glucose, insulin, cholesterol, and triglyceride levels [3].
Magnesium – More than a Mineral
Magnesium is an essential mineral which plays an important role in over 300 enzymatic reactions in the body [4]. It has been shown to support psychological, muscle, and nervous system health and improve energy production and sleep quality [4]. For women managing the demands of daily life alongside hormonal changes, this is a foundational nutrient.
Magnesium supplementation in mental health research typically runs for four to 12 weeks, with some trials extending to six months. Short-term studies have shown improvements in anxiety and depressive symptoms, while longer studies suggest additional benefits for people with chronic mental health conditions – likely linked to magnesium's role in supporting neurotransmitter activity, mood stability, and overall mental well-being [4].
Zinc – Fertility and Reproductive Health
Zinc is a trace mineral involved in a wide range of normal physiological functions, including hormone regulation, immune health, and cell division. Scientific studies show that zinc can contribute to egg quality, fertility, and reproduction, as well as support normal hormonal balance and immune function [5].
Activated Folate (L-5-methyltetrahydrofolate)
Folate is the naturally occurring form of vitamin B9, while folic acid is its synthetic counterpart. Folate plays an essential role in DNA and RNA synthesis, protein production, and normal cell division – making it particularly important in tissues that turn over rapidly.
Folate is especially important during periods of rapid cellular growth – including foetal development, where adequate intake supports normal tissue formation and healthy neural tube development in the growing baby [6].
Vitamin D3, K2, B12, and CoQ10 – A Powerful Micronutrient Matrix
- Vitamin D3 – supports endocrine function and overall well-being
- Vitamin K2 – works alongside D3 to support bone and cardiovascular health
- Vitamin B12 – contributes to normal energy metabolism and the reduction of tiredness and fatigue
- CoQ10 – supports cellular energy production
Phytofemme™ PCOSupport™: Your Convenient All-in-One Option
Phytofemme™ PCOSupport™ is a complete PCOS formulation featuring Myo-inositol and D-chiro inositol at the clinically validated 40:1 ratio, and includes alpha-lipoic acid, magnesium bisglycinate, chromium, methylated B vitamins, zinc, and vitamin D to provide support for reproductive and hormonal health as well as metabolic balance.
Inside the Formula: Why It Works
ALA (alpha-lipoic acid) is a key differentiator in the Phytofemme™ PCOSupport™ formula and provides an additional layer of metabolic support alongside inositol and chromium.
Magnesium bisglycinate is also included at 250 mg elemental magnesium per dose – a meaningful dose delivered in a highly bioavailable chelated form.
Zinc is included in PCOSupport™ as zinc oxide, providing 25 mg of elemental zinc per dose.
Unlike standard folic acid, the folate in PCOSupport™ is provided as L-5-methyltetrahydrofolate – the activated form that the body can use directly, without the conversion step that some women are unable to complete efficiently due to MTHFR gene variants.
Phytofemme™ PCOSupport™ rounds out the formula with a powerful micronutrient matrix of vitamin D3, K2, B12, and CoQ10 – providing support for bone and cardiovascular health, as well as energy production and the reduction of tiredness and fatigue.
Rather than sourcing each of these nutrients separately – and managing multiple capsules daily – Phytofemme™ PCOSupport™ combines them in a single once-daily dose. Mix with 200 ml of water and drink daily, with or without food.
Important note: As of May 2026, PCOS has been renamed PMOS – Polyendocrine Metabolic Ovarian Syndrome. Medical experts changed the name to move away from a misleading label and to better reflect the condition's hormonal, endocrine, and metabolic nature. Read more here.
