Pterostilbene Glucoside (StilbGluc™) supplier specification
Nutrition BioTech is a bulk pterostilbene glucoside ingredient supplier and manufacturer, supplying pterostilbene 4′-O-β-D-glucoside (CAS 38967-99-6) as StilbGluc™ at 99% minimum by HPLC, produced by organic synthesis or enzymatic glycosylation, for B2B nutraceutical formulation.
Pterostilbene glucoside is a distinct chemical entity from pterostilbene — a glycoside, not the aglycone — so it is not interchangeable with pterostilbene on a milligram-for-milligram basis. Every lot ships with a Certificate of Analysis stating identity, HPLC assay and the assay basis.
| Ingredient name | Pterostilbene Glucoside — StilbGluc™ |
|---|---|
| Synonyms | Pterostilbene 4′-O-β-D-glucoside; trans-3,5-dimethoxystilbene-4′-O-β-D-glucopyranoside; pterostilbene glucoside; TDG |
| CAS number | 38967-99-6 |
| Molecular formula | C22H26O8 |
| Molecular weight | 418.44 g/mol |
| Assay / purity | 99% minimum by HPLC, stated on the Certificate of Analysis for each lot. Other grades available on request. |
| Glycoside position | Supplied as the 4′-O-β-D-glucoside. Because several glycosylation positions are chemically possible, the position and anomeric configuration of each lot are confirmed on the specification sheet and by identity testing. |
| Source / production route | Organic synthesis or enzymatic glycosylation of pterostilbene. The applicable route, catalyst or enzyme system and residual solvent limits are stated on the specification sheet. |
| Appearance | White to off-white powder |
| Solubility | Water solubility is higher than that of the corresponding aglycone pterostilbene; soluble in methanol, ethanol and DMSO. Dissolution and dispersion behaviour should be confirmed for the intended dosage form. |
| Relationship to pterostilbene | StilbGluc™ is the glucoside of pterostilbene (pterostilbene CAS 537-42-8, also supplied by Nutrition BioTech as StilbElite™). The sugar moiety adds molecular weight, so equal weights of the two materials do not supply equal pterostilbene-equivalent content. The declaration basis must be agreed before the label is locked. |
| Typical applications | Capsules, tablets, powder blends, stick packs and beverage formats for B2B nutraceutical manufacturing; used where a water-dispersible stilbene format is required |
| Documentation | Certificate of Analysis, specification sheet, identity confirmation (HPLC and spectroscopic), heavy metals, microbiological testing, residual solvents, allergen statement, GMO statement, particle size data and stability data |
| Regulatory note | Permitted use, notification status and labelling requirements for stilbene glycosides differ by jurisdiction. Buyers are responsible for confirming the regulatory position in each market of sale before launch. |
| Quality system | ISO 22000:2018, FSSC 22000, HACCP and GMP (certificates provided on request) |
| Supplier | Nutrition BioTech, 1601 W. Mission Blvd, Suite 103 (DL#29), Pomona, CA 91766, United States |
Pterostilbene Glucoside (StilbGluc™)
Pterostilbene glucoside for differentiated longevity and polyphenol supplement formulas.
Why brands ask for it
StilbGluc™ Pterostilbene Glucoside offers brands a resveratrol-family differentiation story for premium longevity products. It is best used in antioxidant and cellular health stacks where a unique polyphenol angle is valuable.
Finished-product fit
Longevity, antioxidant, cellular health, resveratrol-family upgrade. The strongest conversations start with format, serving size, documentation, and how the material behaves in the intended formula.
What makes the sample useful
- Glucoside differentiation
- Better story than commodity resveratrol
- Fits NAD/polyphenol stacks
Before the sample ships
- Confirm is it different from pterostilbene.
- Confirm dissolution, dispersion, and the intended powder or granule format.
- Confirm source, identity, and supporting documentation.
- Review serving-size logic and label-space fit.
- Review stability expectations and storage conditions for the finished format.
