Four mushrooms for healthy ageing, in the order we would add them. Turkey Tail leads with the highest beta-glucan content we sell, at least 50%. Reishi is second, the most studied mushroom in our range. Chaga is third, the antioxidant one, drunk daily across Siberia for centuries. Tremella is fourth, taken for skin hydration. All four are 10:1 hot water extracts, tested every batch, as powder, capsules or bulk.
Start here. The best evidence-to-product match we have: a randomised trial in healthy people, and the highest measured beta-glucan figure in the range.
Second on the weight of its trial literature, and the one to choose if sleep is the part of ageing well you find hardest.
Third. The practical pick: an extract you enjoy drinking is one you will still be taking in a year, which for this page is the whole point.
| # | Mushroom | Key compound | Best for | From |
|---|---|---|---|---|
| 1 | Turkey Tail | PSP, beta-glucans | Everyday immune and gut support | $29.99 |
| 2 | Reishi | Triterpenes, beta-glucans | Evening wind-down and immune support | $29.99 |
| 3 | Chaga | Melanin, betulinic acid | Antioxidant support | $32.99 |
| 4 | Tremella | Tremella polysaccharides | Skin hydration | $29.99 |
Trametes versicolor
Start here. The best evidence-to-product match we have: a randomised trial in healthy people, and the highest measured beta-glucan figure in the range.
Ganoderma lucidum
Second on the weight of its trial literature, and the one to choose if sleep is the part of ageing well you find hardest.
Inonotus obliquus
Third. The practical pick: an extract you enjoy drinking is one you will still be taking in a year, which for this page is the whole point.
Tremella fuciformis
Fourth, and here because ageing well is partly visible. Tremella is the mushroom taken for how you look rather than how you feel.
What customers report. Individual experience varies; none of this is a clinical claim.
Twenty-four healthy volunteers were randomised to Turkey Tail polysaccharopeptide, to amoxicillin, or to no treatment, with stool sampled seven times over eight weeks. The Turkey Tail group showed clear and consistent shifts in the gut microbiome, consistent with acting as a prebiotic. A randomised trial in healthy people, which is rare and valuable in this field.
Gut Microbes · 2014The widest survey of the Reishi literature: 17 clinical trials covering 971 participants, at doses from 200 to 11,200 mg a day. Pooled analysis found significant improvements in BMI, serum creatinine, glutathione peroxidase and resting heart rate. Many other markers did not move, and the reviewers rate the certainty of the underlying trials as low and call for better-designed studies, which is the usual state of a field this active and this young.
Food Science & Nutrition · 2025The most interesting liver result in the literature. Forty-two adults aged 40 to 54 with mildly raised liver enzymes and fatty liver took 225 mg daily of a triterpenoid and polysaccharide-enriched Ganoderma lucidum or placebo for six months each, in a double-blind crossover; 39 completed. GPT fell from 22.58 to 13.08 U/L and GOT from 20.65 to 15.50, antioxidant capacity and glutathione rose, and markers of oxidative damage fell. A striking effect from a small dose, in the people most likely to notice one, and it deserves a larger trial to confirm it.
Pharmaceutical Biology · 2017A review pulling together the modern research on Chaga: antioxidant, anti-inflammatory and immunomodulatory activity, traced to the melanin, polysaccharides and triterpenes the conk accumulates from the birch it grows on. A consistent laboratory picture, and human trials are the natural next step.
