Frequently Asked Questions

Q: What is the main difference between OPC and regular Grape Seed Powder?

OPC (Oligomeric Procyanidolic Complexes) are the specific, highly active antioxidants extracted from the seed. While regular powder contains these, our extract is standardized to 95-98% OPC, providing a much higher therapeutic concentration.

Q: Is this extract suitable for dietary supplements and cosmetics?

Yes, it is ideal for both. Its high polyphenol content makes it excellent for anti-aging skincare (cosmetics) and its antioxidant properties are highly valued in health supplements for immune and cardiovascular support.

Q: How does the ORAC value relate to product quality?

ORAC (Oxygen Radical Absorbance Capacity) measures the antioxidant potential. Our range of 8,000-18,000 umol/g indicates an extremely high ability to neutralize free radicals compared to standard extracts.

Q: What quality certifications do you follow for heavy metal testing?

We follow strict GB standards (such as GB 5009.11-2010 and GB 5009.12-2010) using AAS (Atomic Absorption Spectroscopy) to ensure lead, arsenic, cadmium, and mercury are well below safety limits.

Q: Can you provide customized specifications for OPC or Polyphenols?

Absolutely. We offer multiple specifications including OPC 95% and 98%, as well as Polyphenols at 80%, 85%, and 90% to meet your specific product formulation requirements.

Q: What is the recommended storage method for this powder?

To maintain maximum potency and shelf life of two years, the powder should be stored in a cool, dry place, kept in its original sealed drum, and protected from direct sunlight.
