Bulk L-ergothioneine: food and cosmetic grade sourcing
Both listed L-ergothioneine grades state 99% minimum. Compare grade, documentation and supply terms before ordering.
What is listed for bulk buyers?
SuperProBio lists L-ergothioneine, also searchable as EGT, in food and cosmetic grades. Each listing states 99% minimum and a 25 kg minimum order. The shared headline specification does not establish that the two grades have identical test requirements or are interchangeable for your application.
Find both EGT listings →Identify the food-grade material
Use product code YJY00003 when requesting the food-grade listing. Include the intended application, specification, required quantity and destination. Ask for the specification and relevant batch information for the proposed supply. Application suitability requires review against your own product requirements.
View food-grade L-ergothioneine →Identify the cosmetic-grade material
Use product code YJY00004 for the cosmetic-grade listing. State the formulation context and any additional tests or documentation your purchasing team requires. A sample request should describe the amount needed and delivery destination; sample availability, cost and freight are confirmed individually.
View cosmetic-grade L-ergothioneine →Separate specification, sample and delivery questions
A complete request identifies the grade and quantity first, then the documents needed for evaluation and the date the material is required. Dispatch preparation and transport are different parts of the timeline. Confirm available quantity and shipment terms in the quotation rather than treating the listing as a live stock record.
Review the ordering steps →Prepare a useful EGT inquiry
Include the product code, target specification, order quantity, required documents and destination. If comparing offers, use the same requirements for each supplier. This guide covers purchasing information only; it does not make claims about health benefits or finished-product performance.
