Tremella fuciformis
Tremella, often referred to as the “snow mushroom,” has been used in traditional Chinese medicine for centuries, particularly for its perceived benefits to skin health, hydration, and longevity. It is commonly consumed in both culinary and medicinal contexts.
More recently, Tremella has attracted scientific interest due to its rich polysaccharide content and its potential effects on hydration, antioxidant status, and metabolic and cognitive health. While much of the evidence is still emerging, its biological properties are increasingly being explored in human and preclinical research.
Tremella contains a range of bioactive compounds:
- Polysaccharides — associated with hydration, immune modulation, and metabolic effects
- Antioxidants — supporting protection against oxidative stress
- Glycoproteins — potentially contributing to cellular hydration and skin health
- Trace minerals — contributing to overall nutritional value
These compounds are particularly notable for their ability to retain water and support cellular resilience.
Randomised, double-blind, placebo-controlled trial · Adults with subjective cognitive impairment · 8 weeks
Tremella supplementation was associated with improvements in subjective memory complaints, short-term memory, and executive function compared with placebo. Suggests Tremella may have benefits beyond traditional hydration-focused uses, with potential relevance for healthy cognitive ageing.

Tremella beverage consumption was associated with improvements in HbA1c and waist circumference. Suggests a possible role in supporting metabolic health, though larger controlled trials are needed.

Tremella has been associated with skin anti-ageing, photoprotection, wound healing, and barrier protection, with most evidence coming from in vitro and in vivo models. Helps support Tremella’s traditional positioning around hydration and skin health, while making clear that stronger human clinical evidence is still needed.
View study on PubMed →Tremella is a multifunctional ingredient that supports hydration, antioxidant defence, and potentially cognitive and metabolic health. While the human evidence base is still developing, its well-characterised polysaccharides and strong mechanistic foundation support its inclusion as part of a diverse, plant-based approach to long-term health.
