Product Introduction

Inositol Powder is a carbocyclic sugar alcohol (cis-1,2,3,5-trans-4,6-cyclohexanehexol), also known as Myo-Inositol. It is a white, odourless crystalline powder that is highly soluble in water, making it easy to incorporate into capsules, pills, powder sachets and beverages.

Myo-Inositol has structural roles in cell membranes (phosphatidylinositol) and participates in insulin signal transduction. Historically, it was categorised as Vitamin B8. It is a favoured functional ingredient in B2B manufacturing due to its clear profile and good compressibility.

Product Specification

Third-Party Test Report

The quality of each batch is verified by internationally recognised third-party testing companies such as SGS and Eurofins before it is shipped.

Testing encompasses pesticide residues, heavy metals, microbiological, moisture content, and specific optical rotation.  Each lot is traceable using our own batch management system. 

We do not send products without passing all pre-shipment examinations.  Test reports are available upon request for every production batch.

Application

Myo-Inositol serves a number of different B2B formulation needs:

Supplements for Women’s Health & PCOS

Inositol is often combined with folic acid or D-Chiro-Inositol at a 40:1 ratio in products aimed for PCOS. Uniform particle distribution offers consistent dosing in clinically sensitive formulations for insulin sensitivity and hormonal support.

Fortification of Infant Formula

Inositol is contained in human breast milk and helps with the development of cell membranes in babies. For this purpose, the powder must comply with strict microbiological criteria (Cronobacter sakazakii negative) and have sufficient stability for thermal spray-drying operations.

Sports Nutrition & Functional Drinks

Used as a lipotropic agent and a cognitive support ingredient in energy drinks and sports powder blends. High water solubility and pH stability aid to preserve the integrity of the label claim during shelf life.

Aquaculture and Animal Feed

It functions as a growth booster and lipotropic drug, preventing fatty liver in carp, salmon, and shrimp. The bulk format makes economical blending into water-soluble feed pellets possible.

COA (Certificate of Analysis)

A complete Certificate of Analysis is provided with every order.  The COA comprises HPLC-confirmed purity (≥99%), LOD values, heavy metal screening, microbiological counts, and physical data such as appearance, mesh size, and bulk density. 

Our in-house laboratory, which meets SGS standards, is equipped with HPLC, UV spectrophotometers, gas chromatographs, atomic absorption spectrophotometers and polarimeters. This device allows for a comprehensive chemical and physical characterisation of each batch.

In case of buyers who require pharmacopeial grade certification, we can match COA criteria with USP, EP or NF monographs upon request.

Production Process

Hongda’s Myo-Inositol is generated by phytin hydrolysis from non-GMO corn steep liquor – the industry standard for the production of nature-identical inositol on a commercial scale.

All steps from raw material intake to final packaging are managed under cGMP standards in a 100,000-level purification workshop. Physical parameters (particle size, bulk density) are modified after processing to meet buyer demands.

Every batch is subjected to HPLC purity verification, testing for heavy metals, screening for microbiological activity and moisture analysis before packaging. Products are packed in double-layer PE bags within fibre drums, with desiccants for long distance shipping stability.

FAQ

Q1: Where do you get your Myo Inositol?

A: It is made by hydrolysis of phytin from non-GMO corn steep liquor. Clean-label product positioning Non-GMO certification documentation available on request.

Q2: What is the effect of the mesh size on my manufacturing process?

A: Most capsule and pill lines use 80-100 mesh. Powder finer than 200 mesh gives problems with hopper flow, while powder coarser than 40 mesh may produce segregation in capsule blends or grit in beverage applications. We specify the proper mesh for your gear.

Q3: Is your Inositol Powder of pharmacopeial grade?

A: Our product is USP Food Grade. Parameters for COA can be matched to USP, EP or NF monographs. If you are using the product for pharmaceutical API use, please Contact Us to discuss GMP documentation requirements unique to your needs.

Q4: How do you prevent caking during transport?

A: LOD is regulated to < 0.5% in production. Each drum is packed in a fibre drum exterior with a double layer PE inner liner with desiccants. This will prevent moisture uptake during ocean freight.

Q5: Is sample available before bulk order?

A: Yes. Samples of 20-100g are offered in aluminium foil bags with inside PE liners. Kindly inform us about your formulation requirements.

Q6. Is Myo-Inositol different from D-Chiro-Inositol?

A: Yes, it is. They are various stereo isomers. Our standard supply is Myo-Inositol (99 % purity). Custom Formulation Service D-Chiro-Inositol or Combined Blends (e.g. 40:1 ratio)
