Snow Mushroom
Also known as: Tremella fuciformis, White Jelly Mushroom, Silver Ear Mushroom, White Wood Ear
Effective Dosage
No established dose from provided studies
What the Science Says
Snow mushroom (Tremella fuciformis) is a white, jelly-like fungus used for centuries in East Asian traditional medicine and cuisine. It contains beta-glucan, a type of soluble fiber thought to support blood sugar regulation and immune function. One small clinical trial found that a daily snow mushroom beverage modestly improved long-term blood sugar markers (HbA1c) and reduced waist circumference in overweight, prediabetic adults over 12 weeks — though the changes were small and the study was exploratory.
What It Doesn't Do
Not proven to reverse diabetes or replace medical treatment. No solid evidence it boosts collagen or gives you glowing skin, despite heavy marketing claims. No proven fat-burning effect. The blood sugar results are preliminary — one small trial is not enough to call it effective. Not shown to improve brain function, immunity, or longevity in humans based on available clinical data.

Absorption & Bioavailability
Unknown — no pharmacokinetic data available from provided studies. Beta-glucan from mushrooms is generally considered poorly absorbed as a whole molecule but may exert effects in the gut.
Red Flags to Watch For
- Only one small clinical trial (56 participants) exists in humans — far too little evidence to make strong health claims
- Heavily marketed for skin and anti-aging benefits with virtually no human clinical evidence to support those claims
- Exact dose used in the one available study was not clearly reported, making dosing guidance impossible
- Often sold in beauty and skincare products at doses with no established efficacy benchmark
- Results from the single RCT were modest (small effect sizes) and the study authors themselves called for larger trials
