What Is D-chiro-inositol?
D-chiro-inositol (DCI) is one of nine known stereoisomers of inositol, a carbocyclic sugar alcohol with distinct physiological roles in human metabolism.
GEM produces D-chiro-inositol through fermentation and membrane filtration, yielding a white crystalline powder with a slightly sweet taste and high water solubility. It is most often formulated alongside Myo-Inositol in women's wellness and metabolic support lines, where the market-standard ratio is 40:1 Myo-Inositol to D-chiro-inositol. GEM can supply standalone DCI or pre-mixed Myo:DCI blends on request.
D-Chiro-Inositol is involved in:
- Cellular signal transduction
- Insulin-related signaling pathways
- Glucose metabolism research
- Hormonal balance studies
- Nutritional supplement development

Three Available Forms
GEM supplies D-chiro-inositol as a free-flowing powder and an engineered granule so manufacturers can match the format to their production line.
D-chiro-inositol Powder
The DCI powder suits sachets, stick packs, bulk blends, and drink mixes. Its high solubility supports beverage and functional food applications where rapid dispersion and a clean taste matter.
D-chiro-inositol Granule
The DCI granule form is engineered for capsule filling and direct compression tableting. Granules improve flow on high-speed encapsulation lines, reducing dosing variability and dust. Both forms share the same assay and impurity profile; GEM can supply either as a pre-mixed Myo:DCI blend.
Production & Quality
GEM's D-chiro-inositol is made by a controlled biotechnology route and released under a documented quality system covering raw materials, in-process controls, and finished-product testing.
Raw material → Fermentation → Membrane Filtration → Enzymatic Conversion → Membrane Filtration → Ultrafiltration → Decolorization → Plate and Frame Filtering → Double Effect Concentration → Crystallization → Centrifugation → Drying → Sieving → Inner Packing → Metal Detection → Outer Packing → Finished Products

Frequently Asked Questions
1. What is a common Myo-Inositol to D-chiro-inositol ratio?
Market formulas frequently use a 40:1 Myo-Inositol to D-chiro-inositol ratio, with 3.6:1 and 10:1 also ok. GEM supplies pre-mixed blends on request to simplify manufacturing and ensure ratio accuracy.
2. What assay grades does GEM supply for D-chiro-inositol?
GEM currently supplies 99.0%–102% HPLC grade only. Lower assay grades (e.g., 95% HPLC) are available from other suppliers in certain markets, but GEM's commercial grade is standardized at the higher purity band.
3. Is GEM D-chiro-inositol REACH registered?
No. GEM does not currently hold a REACH registration number for D-chiro-inositol. Even in Chinese market, there is no DCI registered factory. Contact our sales team for regulatory documentation relevant to your target market and for guidance on compliant importation.
4. What quality documents does GEM provide?
We provide Specification Sheet, COA (Certificate of Analysis), and MSDS upon request, with Kosher, Halal, and ISO/FSSC certificates for qualified commercial orders. These support quality verification and market registration.
5. What is the standard packing and production capacity?
Packed in 25 kg drums with two layers of PE bags inside, D-chiro-inositol is produced at over 30 tons annually via fermentation and membrane filtration, supporting both pilot sampling and commercial volumes. Minimums and lead times are confirmed case by case.
