What the Science Says
MyCommunity is a proprietary blend of 17 medicinal mushroom species, developed by mycologist Paul Stamets. One laboratory study tested different chemical fractions of the blend on human immune cells in a dish, finding that various components activated immune cells and influenced cytokine signaling in different ways. This suggests the blend may have immunomodulatory properties, but no human clinical trials have been published to confirm these effects actually occur when people take it as a supplement.
What It Doesn't Do
Not proven to prevent or treat any disease. No human trial data showing it boosts immunity in real people. Lab results on isolated cells don't guarantee the same effects in your body. Not a cancer treatment or cure. No proven antiviral effect in humans.
Evidence-Based Benefits
Activates multiple immune cell types in laboratory testing, including NK and T cells.

Absorption & Bioavailability
Unknown — the one available study tested isolated fractions on cells in a lab dish, not absorption in humans. Different compounds in the blend have different solubilities, which may affect how much reaches your bloodstream.
Red Flags to Watch For
- Zero published human clinical trials — all evidence is from a single in vitro (cell culture) study
- Proprietary blend means exact amounts of each mushroom species are not disclosed
- Marketing language often implies immune-boosting or disease-fighting benefits not supported by clinical evidence
- Mushroom supplements can interact with immunosuppressant medications — consult a doctor if you are immunocompromised or on such drugs
- Quality and potency can vary widely between batches and brands using similar formulations
