What is PCOS?
Polycystic ovary syndrome (PCOS) is a common endocrine disorder with reproductive and metabolic consequences seen in approximately 1 in 10 people with ovaries. Common symptoms of PCOS include acne, oily skin, excess hair growth on the face, chest and back, hair loss on the head, trouble getting pregnant and carbohydrate cravings.
As PCOS cannot be cured lifestyle interventions including supplement usage is often recommended by nutritionists and dietitians. One commonly recommended supplement for PCOS management is Ovasitol.
What is Ovasitol?
Ovasitol® is a branded inositol supplement from Theralogix Nutritional Science. It is a powdered blend of D-chiro-inositol and myo-inositol. The supplement contains 4000 mg of myo-inositol and 100 mg of D-chiro inositol which is the body’s natural ratio.
Ovasitol is so popular as a supplement for PCOS because it has been independently verified for content accuracy, purity and freedom from contaminants by the National Sanitation Foundation (NSF). It is a USA-made supplement and is gluten-free, dye-free, vegan and unflavored.
What is inositol?
Inositol is a type of sugar alcohol that helps your body process insulin and influences other hormones throughout the body. There are two inositol isomers of interest for PCOS management – myo-inositol and d-chiro-inositol.
As the majority of people with PCOS have insulin resistance, inositol may be a helpful supplement as inositol is considered an insulin sensitiser. This means that it helps the cells in the body be more responsive to insulin, and therefore lets more glucose into the cells, reducing blood glucose levels. This reduction in insulin lowers testosterone levels and restores the FSH/LH ratio in the body.
Benefits of Ovasitol for PCOS
Inositol supplements have various benefits for PCOS. Let’s take a look at the evidence.
A review of twelve randomised control trials found that supplementing with myo-inositol alone or in combination with D-chiro-inositol results in spontaneous ovulation and improves fertility outcomes in people with PCOS.
Improves insulin resistance
A study of 50 people with PCOS who either took inositol plus folic acid or folic acid alone found that those taking inositol had improved insulin sensitivity after twelve weeks of treatment.
Reduces androgen levels
In the above study of 50 people, researchers also found that testosterone levels significantly reduced in those taking inositol for three months.
Regulates the menstrual cycle
A 2022 study found that supplementing with inositol for 6 months resulted in 27% of participants experiencing regular cycles. Plus, the average cycle length dropped from 124 days to 57 days.
Reduces risk of gestational diabetes
People with PCOS are more likely to suffer from gestational diabetes, a type of diabetes that affects people who are pregnant. Supplementing twice a day with inositol reduces the incidence of gestational diabetes by up to 87.3%.
Supports normal lipid levels
A meta-analysis analysed fourteen randomised control trials and found that inositol supplementation in people with metabolic diseases significantly reduced triglycerides, total cholesterol and LDL-cholesterol levels.
Promotes egg quality
Inositol has been seen to help improve egg quality. One study found that myoinositol supplementation for three months improved oocyte maturation.
