FAQ

Q: How do 10:1 extract and 95% Proanthocyanidins differ?

A: The 10:1 ratio means 10kg of raw seeds create 1kg of extract. That 1kg contains 95% proanthocyanidins, the active compound. Ratio represents concentration effort, % purity.

Q: Does your extract contain resveratrol?

A: Resveratrol is found in grape skins, not seeds, hence grape seed extract has a low concentration (<1%). Grape Skin Extract (98% trans-resveratrol) is recommended for resveratrol.

Q: What's the normal post-opening shelf life?

A: 12 months if adequately sealed with desiccant packs in a cool (<25°C), dry, and light-free environment. We put humidity indicators in drums.

Q: Can you help with formulation development?

A: Yes. The applications team offers:

Recommendations for your target claim dosages

Stability testing protocols (heat, pH, light)

Data on excipient compatibility

FDA NDI or EU Novel Food filing regulatory documentation

Q: What if my formula powder clumps?

A: Powder added directly to cold drinks frequently does this. Solution: Pre-disperse 1:10 in warm water (40-50°C) before adding to main batch. Add 0.5-1% silicon dioxide to capsules for flow.

Q: It stable in acidic beverages (pH 3-4)?

A: Proanthocyanidins are pH 3-8 stable. Bioactivity is maintained below pH 3, but color fading may occur over 6+ months.

A: The stock specification is 25kg per drum. Custom extract MOQ is 100kg. Free 100g samples are available before full orders.
