Trans-resveratrol 98% (VineGuard™) supplier specification
Nutrition BioTech is a bulk trans-resveratrol ingredient supplier and manufacturer, supplying trans-resveratrol (CAS 501-36-0) at 98% minimum by HPLC as VineGuard™, produced by microbial fermentation, for B2B nutraceutical formulation.
Two things should be settled before sampling: that the 98% figure is trans-resveratrol rather than total resveratrol, and, for knotweed-derived material, the polycyclic aromatic hydrocarbon limits. Both are stated per lot on the Certificate of Analysis.
| Ingredient name | Trans-Resveratrol 98% — VineGuard™ (fermentation-derived) |
|---|---|
| Synonyms | trans-Resveratrol; (E)-resveratrol; 3,5,4′-trihydroxy-trans-stilbene; 3,4′,5-stilbenetriol |
| CAS number | 501-36-0 (trans-resveratrol). The cis isomer carries a separate number, 61434-67-1; our specifications are written against the trans isomer. |
| Molecular formula | C14H12O3 |
| Molecular weight | 228.24 g/mol |
| Assay / purity | 98% minimum trans-resveratrol by HPLC, with the assay basis stated on the Certificate of Analysis for each lot. |
| Trans versus total resveratrol | Our 98% figure is trans-resveratrol. A total-resveratrol figure on the same lot is a different number, so confirm which basis a competing quotation is written against before comparing prices or fixing label claims. |
| Source / production route | Produced by microbial fermentation followed by isolation and purification. This is a fermentation-derived material, not an extract of Polygonum cuspidatum (Japanese knotweed). The production organism, the fermentation process description and the declarations required in the destination market, including the GMO statement, are provided with the specification sheet. |
| Contaminant control (PAH) | The polycyclic aromatic hydrocarbon and emodin questions that buyers raise about Polygonum cuspidatum extracts arise from the botanical raw material, and do not apply in the same way to fermentation-derived material. Benzo[a]pyrene, the PAH4 sum and emodin can still be tested and reported per lot where a buyer specification calls for them. Residual solvents and fermentation process residues are reported on the Certificate of Analysis. |
| Appearance | White to off-white or light beige powder |
| Solubility | Practically insoluble in water; soluble in ethanol, DMSO and acetone. Wetting behaviour and particle size should be confirmed for the intended dosage form. |
| Stability and handling | Sensitive to light and to alkaline conditions; ultraviolet exposure drives trans-to-cis isomerisation, which lowers the trans assay. Store in tightly closed, light-protected containers. Stability data provided on request. |
| Typical applications | Capsules, tablets, powder blends, beverage and beauty-from-within formats for B2B nutraceutical manufacturing; commonly formulated alongside NMN and NAD precursors, pterostilbene and quercetin |
| Documentation | Certificate of Analysis, specification sheet, botanical or synthetic identity, heavy metals, microbiological testing, residual solvents, pesticide residues, polycyclic aromatic hydrocarbon testing, allergen statement, GMO statement, particle size data and stability data |
| 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 |
Resveratrol (VineGuard™)
Trans-resveratrol platform for antioxidant, NAD-stack and healthy-aging formulas.
Why brands ask for it
VineGuard™ Resveratrol supports classic longevity, antioxidant and NAD-stack formulas. The product page should emphasize trans-resveratrol identity, source options, low-PAH quality control and suitability for capsule, tablet and powder blends.
Finished-product fit
Longevity, healthy aging, antioxidant, NAD stack, beauty from within. The strongest conversations start with format, serving size, documentation, and how the material behaves in the intended formula.
What makes the sample useful
- Trans-resveratrol identity
- Low PAH/source control can be key B2B selling point
- Pairs with NMN/NAD, pterostilbene, quercetin
Before the sample ships
- Confirm trans or total resveratrol.
- Confirm source, identity, and supporting documentation.
- Confirm pAH levels.
- Request contaminant, residual solvent, and microbiology files as needed.
- Review serving-size logic and label-space fit.
