Men’s Health Applications and OEM Expansion for Agaricus KA21
Toei Shinyaku’s outdoor-cultivated Agaricus KA21 has generated useful findings in multiple human studies. In a clinical study involving healthy men and women, participants consumed 1,500 mg of Agaricus KA21 per day for 12 weeks. In another collaborative study with the Faculty of Health Science at Shigakkan University, male senior professional golfers aged 50 to 69 consumed 900 mg per day for two months. The study evaluated men’s health-related measures, including erectile function and other quality-of-life parameters. Based on the accumulated research findings, Toei Shinyaku obtained a patent in February 2026 relating to the use of Agaricus KA21 in the field of men’s health.
The article also notes the material’s strong repeat-purchase performance and its use through medical institutions. Over the most recent year, OEM projects for women-oriented beauty salons and hair salons have also been expanding. Toei Shinyaku has continued to develop OEM applications using Agaricus KA21 for a variety of target markets.
Further Functional Research
Toei Shinyaku continues to investigate additional functions of Agaricus KA21. At the 26th Annual Meeting of the Japanese Society of Anti-Aging Medicine held in June 2026, the company and Tokyo University of Pharmacy and Life Sciences presented new findings concerning β-glucans derived from Agaricus KA21. The research was selected as an excellent presentation at the meeting.
