Inositol vs Myo Inositol: Key Differences Explained for Health

Both inositol and myo inositol are biological compounds that are found in our bodies and many foods. They are often used as supplements to sustain overall health and address specific conditions. However, despite having similar names, inositol, and myo inositol differ in their properties and benefits.

Key Takeaways:

  • Inositol and myo inositol are natural compounds found in the body and many foods.
  • They are often used as supplements to support overall health and address specific conditions.
  • Inositol and myo inositol have unique properties and benefits.
  • Comprehending the differences between these two compounds can help individuals choose the right supplement for their health goals.

What is Inositol?

Inositol is a type of sugar alcohol innately found in various foods, including fruits, beans, and nuts. The human body also produces it and involves many physiological processes. Inositol is also typically called “vitamin B8,” although it is not a vitamin.

What is Myo Inositol?

Myo-inositol, also known as myo-inositol or simply inositol, is a naturally occurring chemical compound discovered in foods such as fruits, beans, and grains. It is a stereoisomer of inositol, suggesting it has the same chemical formula but a slightly different molecular structure. Myoinositol serves several essential functions in the body, such as regulating insulin sensitivity, supporting healthy brain function, and aiding in the production of serotonin.

Health Benefits of Inositol

Inositol is an innately occurring carbohydrate compound used by the body to support various functions. Inositol has been linked to several potential health benefits, including:

  1. Improving PCOS symptoms: Inositol may help improve insulin opposition in women with polycystic ovary syndrome (PCOS), leading to more regular menstrual cycles and enhanced fertility.
  2. Reducing anxiety and depression: Inositol has been shown to have a calming effect on the brain, potentially reducing symptoms of anxiety and depression.
  3. Lowering cholesterol: Inositol may help lower LDL (the “bad” cholesterol) levels in the blood, minimizing the risk of heart disease.

While these health benefits are promising, more research is needed to understand the full extent of inositol’s effects on the body.

Health Benefits of Myo Inositol

Myoinositol is a type of inositol that has gained attention for its possible health benefits. Here are some of the uses of Myo inositol:

  • Fertility: Myo inositol has been shown to improve fertility in women with conditions such as polycystic ovary syndrome (PCOS) and other hormonal imbalances. It may help control menstrual cycles and promote ovulation, making it a popular supplement for women trying to conceive.
  • Depression and anxiety: There is some evidence to suggest that myoinositol may have a positive effect on mood conditions such as depression and anxiety. It may help regulate neurotransmitters in the brain, improving symptoms of these conditions.
  • Metabolic health: Myoinositol has improved insulin sensitivity and receded insulin resistance in people with type 2 diabetes. It may also positively affect cholesterol levels, reducing the risk of heart disease.

If you consider adding myoinositol to your supplement regimen, you must talk to your healthcare provider first. They can help you determine the right supplement for your health needs and advise you on the appropriate dosage.

Differences Between Inositol and Myo Inositol

While inositol and myo inositol are often used interchangeably, they are two distinct compounds that differ in several important ways. Firstly, inositol is a broad term that encompasses a group of nine different isomers, one of which is myo inositol. Myo inositol, on the other hand, refers specifically to one of these isomers.

Chemically, inositol and myo inositol have the same basic structure: a six-carbon ring with a hydroxyl group (-OH) attached to each carbon. However, myo inositol has an additional -OH group on the fifth carbon, a difference that affects its metabolism and subsequent physiological effects.

Given these differences, it is essential to carefully consider which form of inositol is best suited to your individual health needs. Your healthcare expert can help you decide which form and dose of inositol is most appropriate.

Side Effects of Inositol

Inositol supplementation is commonly thought safe and well-tolerated by most individuals. However, like any supplement, there are potential side effects to be aware of.

It is essential to note that inositol may interact with specific prescriptions, such as lithium, used to treat bipolar disorder. Inositol may enhance the risk of lithium toxicity and should only be taken under the direction of a healthcare provider.

Inositol Supplements: How to Choose the Right One

When supplementing with inositol, choosing the right product that suits your needs is essential. Here are some factors to consider when selecting an inositol supplement:

Factor Considerations
Dosage Check the suggested dosage and make sure it aligns with your health goals. Some products may contain a combination of inositol and other ingredients, so read the label closely to ensure you are taking the right amount of inositol.
Form Inositol supplements are available in several forms, including powder, capsules, and tablets. Consider your personal preferences and ease of use when selecting a form of inositol.
Quality Choose a reputable brand and ensure the product is third-party tested for purity and potency. Look for supplements free from fillers, additives, and artificial ingredients.
Inositol : Myo Inositol Ratio Depending on your health goals and condition, you may want to consider the ratio of inositol to myo inositol in the supplement. For example, some products may contain a 40:1 or 2:1 ratio of myo inositol to inositol, which may benefit those seeking to improve fertility or manage PCOS.


Overall, both inositol and myoinositol can offer a range of health benefits, including their possible roles in managing PCOS, improving mental health, and aiding in fertility and reproductive health. However, it is essential to comprehend the differences between the two and select the supplement that best aligns with individual health goals.

Final Thoughts

If you’re thinking of combining inositol or myoinositol into your health regimen, it’s essential to consult with a healthcare expert first. Inositol and myoinositol are pledging options for managing specific health concerns, but personal results may vary. With proper use and under medical supervision, these supplements may significantly benefit overall health and well-being.
