What Is Inositol and How Does It Work?
Inositol is a naturally occurring carbohydrate-like compound found in all cell membranes, with particularly high concentrations in the brain and centre nervous system. Often referred to as a pseudovitamin, it is not an essential nutrient but plays a vital role in cellular signalling and metabolic processes. The most common form used in supplements is myo-inositol, which is the form found in NOW Foods Inositol 500 mg. This form is crucial for proper insulin action and helps maintain cellular calcium balance, supporting overall cellular health.
Who May Benefit from Inositol?
Inositol is widely used by individuals seeking to support mental wellbeing, metabolic health, and overall cellular function. It is particularly popular amongst those following a vegan or plant-based diet, as inositol is found in animal products and certain plant foods. People with concerns about blood sugar balance, insulin sensitivity, or hormonal health may also find inositol helpful. Additionally, because of its role in neurotransmitter signalling, it is often taken to promote a calm mood and stress resilience. Always consult a health care professional before starting any new supplement.
Top Forms of Inositol: Myo-Inositol vs. D-Chiro-Inositol
Inositol exists in nine different stereoisomers, but the two most common in supplements are myo-inositol and D-chiro-inositol. Myo-inositol is the predominant form in the body and is directly involved in cell signalling and insulin action. D-chiro-inositol is a derivative that also supports insulin function but in a different manner. Most research focuses on myo-inositol, making it the preferred choice for general health support. NOW Foods Inositol provides 500 mg of myo-inositol per capsule, allowing flexible dosing.
How to Choose a Quality Inositol Supplement
When selecting an inositol supplement, look for the following factors to ensure you are getting a high-quality product:
-
Form: Myo-inositol is the most studied and bioavailable form. Avoid products that use mixed forms unless specified.
-
Purity: Choose supplements that are free from unnecessary additives, binders, and fillers. NOW Foods Inositol is non-GMO, vegan, soy-free, and kosher certified.
-
Third-Party Testing: GMP Quality Assured certification means the product has been tested for stability, potency, and formulation by an ISO/IEC accredited lab.
-
Dosage: A typical dosage ranges from 500 mg to 2,000 mg per day, depending on your needs. Start with a lower dose and adjust as needed.
Key Benefits of Inositol Supplementation
Inositol supports general health through its involvement in cell membrane function and signalling pathways. Here are some areas where it may be of interest:
-
Membrane Function*: Inositol is a structural component of cell membranes, contributing to their integrity and fluidity, which is important for nutrient transport and intercellular communication.
-
Cellular Health*: Inositol is involved in neurotransmitter signalling in the brain, which may support cognitive function and mood balance as part of a healthy lifestyle.
-
Metabolic Support*: Myo-inositol plays a role in insulin signalling and lipid metabolism, and is often included in dietary approaches to support blood sugar balance.
-
Calcium Homeostasis*: Inositol helps regulate calcium levels within cells, a process that supports muscle contraction, nerve transmission, and bone health.

FAQs About Inositol
Q: Can inositol be taken with other supplements?
A: Inositol is generally safe to combine with other vitamins and minerals. It is often taken alongside B-complex vitamins or magnesium for synergistic benefits. However, consult your health care provider if you are taking medications for blood sugar or mood disorders.
Q: Is inositol the same as vitamin B8?
A: Inositol is sometimes called vitamin B8, but it is not officially classified as a vitamin. It is considered a pseudovitamin because the body can produce it from glucose, and it is not an essential dietary nutrient.
Q: How should I take inositol?
A: The recommended serving is one capsule (500 mg) up to two times daily, preferably with meals. For higher doses, consider a powder form for easier administration.
