Buyer summary: A conventional active powder and a product sold as a liposomal powder are different sourcing briefs. The concentration printed in one product name may not be measured or expressed on the same basis as the other. Do not infer encapsulation quality, absorption, stability or finished-product performance from the word “liposomal” alone.
Start with exact identity. Compare the same named active before comparing formats. For glutathione, the site lists Reduced L-Glutathione Powder 98% alongside Liposomal Glutathione Powder 50% and Liposomal Glutathione Powder 70%. These are separate listed grades. Ask which chemical form, active-content basis and other components are included in the offered specification. A 70% title and a 98% title should not be compared as if they describe an identical material on an identical basis.
Then establish the format brief. NMN Powder 99%, Liposomal NMN Powder 50% and Liposomal NMN Powder 70% illustrate another active with multiple named forms. State whether your formulation needs a conventional active, a liposomal-labelled powder or both for evaluation. Ask for the current composition and specification of each candidate, including any carrier or excipient information relevant to your label and quality review.
Keep different actives separate. A Curcumin Extract Powder 95% and Liposomal Curcumin Powder 70% belong in a curcumin comparison, not in an NMN or glutathione comparison. Even within the same active, confirm the analytical method and percentage basis before comparing quoted prices per kilogram or setting an input level.
Documents to request for the exact grade: Obtain the current product specification; identity and active-content method; full composition or carrier information needed by your quality team; relevant physical-format information; and batch documents if available for the offered lot. Where a liposomal characteristic matters to your brief, ask how that characteristic is defined and evidenced. Do not turn a supplier’s format label into a product claim without your own regulatory and technical review.
RFQ checklist: Include the exact active and product name, desired form, target active-content basis, intended application, destination market, approximate quantity, packing needs and the documents required before a sample or quotation can be approved. If conventional and liposomal-labelled options are both acceptable, ask for separate specifications and quotations so each can be evaluated on its own terms.
Browse the specialty and liposomal ingredient directory to identify the correct product. Send a specification-led inquiry with the exact grade and documents you need.
