This site's own FAQ addresses this directly: adults, especially older adults, who want general daily support for memory and focus as part of healthy aging, and who are comfortable with a formula that names only some of its ingredients.
Worth reading this FAQ answer as directly repeating the partial-disclosure comfort point from the site's own "sensible fit" list — worth noting this site considers that transparency question central to audience fit, not a minor footnote.
This site separately names "healthy aging brain" as a benefit tied to Lion's Mane specifically — worth reading that benefit alongside this FAQ answer's emphasis on older adults.
