Procurement FAQ
Questions supplement brands ask before sourcing
Answers below are intentionally scoped to preliminary B2B evaluation. Product-specific claims, compliance and suitability must be confirmed for each target market and finished formula.
Ask a product-specific question →The core group contains ingredients that directly fit the collagen category: marine collagen, bovine collagen, collagen type II and eggshell membrane collagen. The complementary group contains commercially relevant proteins and peptides used in adjacent supplement concepts, including keratin, elastin, beef protein and bone broth proteins.
Yes. Include the product, intended application, target market and estimated volume so the team can provide the most relevant available documentation and discuss sample evaluation.
Gensei presents both pathways: bulk raw-material supply and finished-format manufacturing services such as powders, capsules, tablets, gummies and custom formulations. The commercial requirements differ by project.
Provide the ingredient name, dosage form, target market, annual or initial volume, desired packaging, timeline and whether you need a sample, COA, specification or formulation discussion first.
The current website states that California warehouse and North America buyer coordination are available. Confirm current stock, lead time and product eligibility directly with the sales team for each inquiry.
