How This Grade Differs
Oyster extract powder is listed as Crassostrea gigas with natural taurine 85% by HPLC. The linked 50% oyster grade has a different declared content; single-entity taurine powder is a separate purchasing specification with no oyster source stated on its page. Confirm source and current batch documents before substitution.
