Snow Fungus
Also known as: Tremella fuciformis, White Jelly Mushroom, Silver Ear Mushroom, White Wood Ear, Bai Mu Er
Effective Dosage
No established dose
What the Science Says
Snow fungus is an edible white mushroom (Tremella fuciformis) used for centuries in Traditional Chinese Medicine, often for skin hydration, immune support, and cognitive health. It contains polysaccharides that may have antioxidant and moisturizing properties in lab studies. The only available clinical trial tested it as part of a multi-ingredient formula alongside fish roe and yeast, making it impossible to isolate snow fungus's specific effects on cognition or any other outcome.
What It Doesn't Do
Not proven to boost memory or cognition on its own — the one clinical trial tested a blend, not snow fungus alone. No solid evidence it improves skin from the inside. Not a proven immune booster in humans. Don't expect anti-aging miracles based on traditional use alone.

Absorption & Bioavailability
Unknown — no human pharmacokinetic data available from provided studies
Red Flags to Watch For
- Pesticide contamination is a real concern: one study found pesticide residues (including carbofuran, acetamiprid, and imidacloprid) in nearly 66% of tested snow fungus samples from major production areas
- The only clinical trial tested a multi-ingredient blend, so no benefit can be attributed to snow fungus specifically
- Widely sold in supplements despite almost no standalone human clinical trial data
- Products in the NIH DSLD database number over 1,000, far outpacing the actual clinical evidence base
