Raw material sourcing by kg
Trans-Resveratrol–Red Wine Extract Blend
Prepare a kg-based purchasing discussion for trans-resveratrol together with red wine extract. Identify the knotweed-root and grape-skin preparations separately before comparing supplier proposals.

Define your ingredient input
The two-input group retains trans-resveratrol with Polygonum cuspidatum root source context and red wine extract from Vitis vinifera grape skin. Compare the two actual preparations and proposed composition without adding grape seed extract or assuming a supplied softgel. Soybean oil, gelatin and vegetable glycerin belong to the ancillary declaration to confirm for the actual proposed material.
Discuss your procurement requirements
- Does the complete proposed active group contain trans-resveratrol and red wine extract as two separately declared inputs?
- How will the supplier identify the Polygonum cuspidatum root context for the trans-resveratrol preparation without assuming a verified batch origin?
- Does the red-wine extract declaration identify Vitis vinifera grape skin, and how is its actual preparation characterized?
- How will the complete two-input declaration be distinguished from a separate three-input grape-seed/red-wine/resveratrol composition?
- Which identity and isomer-reporting methods should distinguish requested trans-resveratrol from a generic resveratrol-family declaration?
- What relative composition and actual physical delivery form should be agreed without copying illustrative serving amounts?
- Which actual roles, preparations and inclusion declarations apply to the proposed ancillary context: Gelatin shell context; Soybean oil; Vegetable glycerin; complete shell/water/other ancillary system to confirm?
- Which identity, composition and other requested analytical methods and documents should support comparison of supplier proposals?
- What evaluation-sample quantity, handling, compatibility and storage questions should be agreed with the proposed supplier?
- What purchasing quantity in kg, intended formulation, destination and packaging requirements should be reviewed before commercial terms are agreed?
Confirm the offered specification, analytical methods, sample arrangements and documentation with the proposed supplier for your intended project.
Named ingredient composition
- Trans-resveratrol; Polygonum cuspidatum root identity to confirm
- Red wine extract; Vitis vinifera grape-skin preparation to confirm
Agree the complete proposed composition, ingredient roles and preparation details with the supplier. This list does not establish a supplied batch or specification.
Procurement questions and answers
Does this composition also include grape seed extract?
No grape-seed input is added to this two-input brief. A grape-seed/red-wine/resveratrol composition is a different complete group.
Is red wine extract the same input as trans-resveratrol?
They are separately declared here. Ask for the actual red-wine extract preparation and the trans-resveratrol identity rather than merging the two into one ingredient name.
Are soybean oil or gelatin fixed supply requirements?
They are retained as ancillary context for clarification. The actual kg material, carrier and shell ingredients if relevant, sample presentation and commercial terms require supplier confirmation.
