Tremella polysaccharide: The molecular mechanisms of its drug action
Progress in molecular biology and translational science (2019) · Systematic review
In this chapter, 113 independent studies involving in biochemical, pharmacological, and clinical studies of TFPS during the past 46 years (1972-2018) on the base of PubMed, CNKI (China National Knowledge Infrastructure) and Wanfang database search are summarized.
The ONTRAC RCT used 500 mg twice daily (1000 mg/day total) and reduced new non-melanoma skin cancers by 23%. Effect requires continuous use; it disappeared after discontinuation. Curve is indicative — only the 1000 mg/day regimen is directly RCT-supported.
Based on 2 RCTs showing improvements in memory and response times. One study used snow fungus in combination with other ingredients, limiting specificity to Tremella alone. Adverse event rates were similar across groups (35-41%).
AI-estimated from published studies. Interpret as directional guidance.
Both Nicotinamide and Tremella are closely matched — the best choice depends on your specific health goals.
For healthy aging, Tremella has a higher relevance score (70 vs 50).
