Inositol CAS#87‑89‑8
Inositol, also known as hexahydroxycyclohexane, is a naturally‑occurring substance broadly found in plant and animal tissues. In animals, high concentrations of inositol exist in the brain, heart, stomach, kidney, spleen and liver, either in its free form or as a constituent of phospholipids. For plant sources, cereals contain abundant inositol, mostly presented as phytic acid, a type of polyphosphoric acid ester.
Multiple optically active and inactive isomers of inositol exist. For food‑additive applications, the target substance is myo‑inositol, the optically‑inactive cis‑1,2,3,5‑trans‑4,6‑cyclohexanehexol. Pure inositol is a stable, white, sweet‑tasting crystalline compound.

Inositol CAS#87‑89‑8
H2: Product Overview
Inositol acts as an essential vitamin‑like substance participating in lipid metabolism within organisms. It facilitates absorption of lipid‑lowering drugs and vitamins, accelerates cell growth and fat metabolism in liver and other tissues, and can serve as auxiliary support for fatty liver and high‑cholesterol related conditions. It is widely adopted as food and feed additive, with typical addition dosage of 350‑500 mg/kg in feed for fish, shrimp and livestock.
H2: Core Application Scenarios
H3: Nutrition & Functional Food Industry
Inositol can be incorporated into functional food formulations, nutritional premixes and dietary supplements. It supports human lipid balance and cell membrane health, and is commonly applied in nutritional fortification for special‑diet food products.
H3: Aquaculture & Livestock Feed Additive
As a vital feed additive for fish, shrimp and livestock, it is dosed at 350‑500 mg/kg in feed formula. It promotes animal cell growth, optimizes fat metabolism and reduces the risk of inositol deficiency in aquatic and poultry‑livestock breeding.
H3: Pharmaceutical‑related Auxiliary Usage
It assists lipid‑regulating efficacy of hypolipidemic agents and vitamins. It can be used for adjuvant support for fatty liver and high‑cholesterol scenarios, working together with corresponding pharmaceutical raw‑material systems.
H3: Extended Industrial Usage
Inositol can also be deployed as biochemical raw material and microbial culture medium component for fermentation industry, supporting synthesis of downstream inositol‑derived chemical substances.
H2: Key Product Advantages
H3: Reliable Nutritional Activity
This myo‑inositol grade maintains stable nutritional performance for lipid metabolism. It delivers consistent bio‑availability for both food fortification and feed‑formula blending.
H3: Good Physical Handling Performance
White crystalline powder features favorable water‑solubility, easy dispersion during mixing with other food or feed raw materials, bringing convenience for formula preparation.
H3: Strict Batch‑wise Quality Control
Every batch undergoes lab inspection to confirm purity, heavy‑metal and impurity indicators, to meet food‑grade and feed‑grade compliance requirements. Long‑term supply contracts are available for large‑scale food factories and feed enterprises.
H2: Packaging, Storage & Transportation
H3: Standard Packaging Specification
Standard bulk packing: 25 kg food‑grade paper drum with inner PE liner. The inner liner achieves moisture‑proof protection; outer paper drum offers mechanical strength for sea‑land bulk shipment. Customized packaging solutions are negotiable for special project requirements.
