What is Inositol?
Inositol, a naturally occurring cyclohexanehexol compound (CAS Number: 87-89-8), also known as myo-inositol, cyclohexane-1,2,3,4,5,6-hexol, or cis-1,2,3,5-trans-4,6-cyclohexanehexol, is a carbocyclic sugar with molecular formula C₆H₁₂O₆ and molecular weight of 180.16 g/mol. The most popular and biologically relevant form of inositol is myo-inositol, which is widely available as a white to off-white crystalline powder with 99% purity specifications, offering high bioavailability when consumed orally, though exact absorption rates may vary between individuals. Inositol is found naturally in various foods including fruits (especially citrus), beans, grains, and nuts, as well as being synthesized in the human body, primarily in the kidneys. Provita Biotech is the leading bulk Inositol Powder supplier in China, providing high-quality pharmaceutical and nutritional grade inositol to global markets for use in dietary supplements, pharmaceuticals, and functional foods.
myo inositol vs inositol
Inositol (cyclohexane-1,2,3,4,5,6-hexol) exists in nine distinct stereoisomeric forms due to the different possible spatial arrangements of its six hydroxyl groups around the cyclohexane ring. These nine stereoisomers are:
Myo-inositol (CAS: 87-89-8) – The most abundant and biologically relevant form in nature, accounting for over 95% of inositol in the human body. It has a unique “chair” conformation with one axial hydroxyl group and five equatorial hydroxyl groups.
D-chiro-inositol (CAS: 643-12-9) – The second most studied isomer, important for insulin signaling. It differs from myo-inositol in the orientation of one hydroxyl group.
Scyllo-inositol (CAS: 488-59-5) – A symmetrical isomer with all hydroxyl groups equatorial. It has shown potential in Alzheimer’s disease research.
Muco-inositol (CAS: 488-54-0) – A less common isomer with limited biological significance.
Neo-inositol (CAS: 488-58-4) – A rare isomer with minimal presence in biological systems.
Allo-inositol (CAS: 488-56-2) – Another rare isomer with limited biological activity in humans.
Epi-inositol (CAS: 488-57-3) – Has shown some promise in experimental research but is not commonly found in nature.
L-chiro-inositol (CAS: 22318-58-5) – The enantiomer of D-chiro-inositol, less biologically active in humans.
Cis-inositol (CAS: 593-20-4) – The least common isomer, rarely found in biological systems.
Of these nine stereoisomers, only Myo-inositol and D-chiro-inositol have significant biological roles in human physiology and are the most extensively studied for therapeutic applications.
Myo-inositol is actually the most common and biologically active form of inositol, making the comparison somewhat misleading as “inositol” typically refers to myo-inositol in dietary supplements. When specifically comparing myo-inositol to other inositol isomers, myo-inositol generally offers superior bioavailability, more extensive research backing, greater popularity, and broader clinical applications. For most health applications including reproductive health, metabolic support, and mood regulation, myo-inositol is the preferred choice, though specific conditions may benefit from particular isomers or combinations.
D-Chiro inositol (DCI) is a distinct isomer of inositol that differs from myo-inositol in the orientation of one hydroxyl group. With CAS number 643-12-9, D-chiro inositol plays a unique role in insulin signaling pathways and is found naturally in the body, though in much smaller quantities than myo-inositol. The body can convert myo-inositol to D-chiro inositol via an insulin-dependent epimerase enzyme.
Benefits of D-Chiro Inositol:
- Enhanced insulin sensitivity and glucose metabolism
- Reduction of androgen levels in women with PCOS
- Improvement in ovulation frequency in PCOS patients
- Complementary effects when combined with myo-inositol
- Potential benefits for metabolic syndrome
- Support for weight management
D-Chiro inositol is primarily used in specific clinical contexts, often in combination with myo-inositol in a 40:1 ratio (myo) to mimic the natural ratio found in plasma. This combination approach has shown particular promise for women with PCOS, insulin resistance, and fertility challenges.
