If you're looking for broad immune and cognitive support, this blend combines seven mushroom species — **Lion's Mane**, **Reishi**, **Cordyceps**, **Maitake**, Chaga, Royal Sun Blazei, and Mesima — at 214mg each per serving (1.5g total). The species selection covers a wide range of studied benefits.

The dose challenge is significant. Clinical trials on individual mushrooms typically use 1,000–3,000mg of a single species. At 214mg per mushroom, each species is dosed at roughly 7–21% of its individually studied range. This is a common tradeoff with multi-mushroom blends — you get variety but not the doses that drove results in published research. The product also uses mycelium grown on brown rice, which means some of each 214mg includes the rice substrate, not pure mushroom.

If you're drawn to a specific benefit — like Lion's Mane for cognition or Reishi for immune support — a single-species product at clinical doses would give you a better chance of matching the research. This blend works as a general daily mushroom supplement, but the per-species doses are well below what's been studied.
