What GLISERA EGT® refers to

GLISERA EGT® is a trade name for a branded L-ergothioneine ingredient. EGT is the common trade shorthand for ergothioneine. The brand covers one defined material: ergothioneine naturally extracted from golden oyster mushroom.

A trade name ties an ingredient to one producer's process and documentation. Generic ergothioneine carries no such link. That is why brand owners often specify a branded ingredient by name in their supplier contracts.

How FC Materials supplies it

FC Materials does not manufacture GLISERA EGT®. FC sources it from a trusted global partner and acts as the sourcing partner for manufacturers and brand owners. FC helps with cost, quality and documentation.

The main resource is the GLISERA EGT® branded page. It sets out the ingredient profile and how to request documentation and specifications.

Using the brand name on pack

Many brand owners want to show a branded ingredient on their label. Before printing GLISERA EGT® on artwork, confirm the trademark terms with the supplier. Ask whether artwork approval is needed and whether co-branding guidelines exist.

Formulation notes

  • Compare the suggested use stated on the branded page with your planned serving size.
  • Assess colour and odour in the finished product before committing to a format.
