Inositol (CAS 87-89-8), specifically the myo-isomer, is a carbocyclic sugar naturally abundant in biological systems, functioning as a vital component of cell membranes and a secondary messenger in insulin signaling. Chemically identified as cis-1,2,3,5-trans-4,6-Cyclohexanehexol, this sweet-tasting white crystalline powder acts to support lipid metabolism and regulate cellular response to hormones. Historically classified as Vitamin B8, it is extensively integrated into infant formula (to support growth), functional beverages (often paired with Taurine), and aquaculture feed (to promote growth in fish and shrimp). In the pharmaceutical sector, it is a key ingredient in supplements for Polycystic Ovary Syndrome (PCOS) management due to its insulin-sensitizing effects. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific mesh sizes and purity standards (e.g., NF/FCC/Feed Grade). Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Product Description
Inositol, specifically the Myo-Inositol isomer, is a carbocyclic sugar that is abundant in the brain and other mammalian tissues. It is a slightly sweet white powder (about half the sweetness of sucrose) and is water-soluble.
Why is it popular?
- Energy Metabolism: It aids in the breakdown of fats and reduces blood cholesterol, making it a staple in “Energy Drinks” alongside Taurine and Caffeine.
- Women’s Health: It is extensively used in supplements to support hormonal balance, particularly for Polycystic Ovary Syndrome (PCOS) management and insulin sensitivity.
- Cell Growth: It acts as a growth factor for cells, which is why it is added to infant formula and high-quality animal feed (aquaculture).

FAQ - Technical & Supply Chain
-
Q:
What is the relationship between Inositol CAS 87-89-8 and Myo-Inositol?
A: "Inositol" is a general term for a group of nine stereoisomers, but in commercial trade and biological contexts, CAS 87-89-8 refers specifically to Myo-Inositol, which is the most stable and biologically active form (accounting for >99% of the market). -
Q:
Is this ingredient suitable for use in aquatic feed?
A: Yes, Inositol is a critical growth factor for aquatic species (especially carp and shrimp); deficiency in feed can lead to slow growth and skin lesions, making it a standard additive in high-quality aqua-feed formulations.
