Description
Products Description
Grape Seed Extract, standardized to its oligomeric proanthocyanidin (OPC) content, is derived from the seeds of Vitis vinifera and represents one of the most established antioxidant raw materials in the supplement industry. OPCs are a heterogeneous class of flavonoid compounds - built from catechin, epicatechin, and related monomer units assembled into dimers, trimers, and larger oligomers - making accurate potency verification more complex than testing a single-compound active. The commonly cited "95% OPC" figure varies meaningfully in reliability depending on whether it was determined by UV spectrophotometry alone or confirmed with HPLC.
Sheerherb's Grape Seed Extract (OPC 95%) is extracted from Vitis vinifera seeds and tested using both UV assay and HPLC confirmation, giving formulators a more reliable potency figure than UV-only testing alone. We supply supplement manufacturers, functional beverage producers, and cosmetic formulators sourcing standardized OPC raw material for antioxidant and cardiovascular-support product lines.

Product Benefits
Grape Seed Extract (OPC 95%) is valued mainly for its oligomeric proanthocyanidin content, which underpins most of its functional positioning:
1. Antioxidant Formulations
As one of the most potent natural free-radical scavengers, OPC is a foundational ingredient in antioxidant-positioned supplement and skincare formulas.
2. Cardiovascular & Vascular Health Positioning
Its association with blood pressure, lipid profile, and vascular health support makes it a common ingredient in heart-health and circulation-focused formulas.
3. Skin & Cosmetic Applications
Its antioxidant activity and traditional use in beauty treatments support inclusion in anti-aging and skin-protective cosmetic formulations.
4. Reliable, Dual-Verified Potency
Pairing UV assay with HPLC confirmation gives formulators a more trustworthy specification than the single-method UV testing common across the category.
Products Applications
Dietary Supplements
Standardized, dual-verified OPC content supports capsule and tablet formulations targeting antioxidant and cardiovascular-support claims.
Functional Beverages
Water and ethanol solubility support inclusion in antioxidant-focused beverages and functional drink formulations.
Cosmeceuticals
Its antioxidant activity supports inclusion in anti-aging serums, creams, and treatment products targeting skin protection.

FAQ
Q: What specifications do you offer for bulk orders, and how is potency verified?
A: 95% total proanthocyanidins by UV assay, with HPLC confirmation of the oligomeric (OPC) fraction to address the overestimation risk common with UV-only testing. Specs can be adjusted to your formulation target, with COA, MSDS, and microbiological reports provided per batch.
Q: What is your MOQ for wholesale orders?
A: MOQ typically starts from 1kg for trial quantities, up to 25kg drums for commercial orders. Flexible terms available for long-term partnerships.
Q: Why does the testing method (UV vs. HPLC) matter for this ingredient?
A: UV spectrophotometry is the standard commercial method but can be affected by other polyphenolic compounds in the grape seed matrix, sometimes overestimating true OPC content by 5%–15%. HPLC confirmation separates and quantifies individual proanthocyanidin species, giving a more reliable potency figure - we provide both on request.
Q: How do you ensure quality and stability during shipping?
A: Controlled extraction process, packed in light-protective, moisture-resistant packaging. Recommend storing in a cool, dry place away from strong light and heat.
Q: Do you support OEM/private label projects?
A: Yes - including custom blends with vitamin C or resveratrol for antioxidant and cardiovascular-support formulas. Our team can advise on compatibility for qualifying volumes.
