アガリクス(姫マツタケ) (Agarikusu / Himematsutake)

Japanese producers refined the himematsutake cultivar and developed the standardised beta-glucan extracts that anchor the global agaricus supplement category.
Beta-glucan 25-45% in standardised extracts; ergosterol 0.05-0.2%; protein 30-50% (dried mushroom basis).
Immune-support supplements, adjuvant nutraceuticals, functional tea blends.
Cultivated medicinal mushroom (Agaricus blazei), introduced from Brazil but commercialised in Japan since the 1980s, where the cultivar has been refined and standardised under the local 'himematsutake' trade name. Major Japanese producers operate indoor cultivation in Mie, Niigata, and Hokkaido. Beta-glucan-rich extracts are positioned for immune-support supplementation domestically (FFC notifications exist) and exported substantially to North American and Asian supplement markets. Important historical caveat — early-2000s heavy-metal compliance concerns drove tighter quality standards that responsible producers have long since addressed.
