Customer reviews
- ★★★★☆Gemma F.14/05/2026Good for mental stamina
I use this primarily for stamina during long creative work sessions. It helps me stay sharp for longer without that late-afternoon cognitive collapse. Happy with the results.
- ★★★★★Emma W.Verified buyer10/05/2026Brain fog completely lifted
Post-viral brain fog for 8 months was affecting my work. GP had no solutions. Naturopath suggested lion's mane. After 6 weeks the mental clarity has returned significantly. The NGF-stimulating mechanism is plausible and the research is growing.
- ★★★★★Aisha R.07/05/2026Great product, solid effects
I work as a solicitor and focus is everything. This has genuinely helped with sustained concentration during complex casework. No jitters, no crash. Very pleased.
- ★★★★★Hannah L.05/05/2026Better memory and focus
I'm 48 and started to notice some memory lapses. Three months on lion's mane and my recall is noticeably improved. I also feel more focused during meetings.
- ★★★★★Oliver S.23/04/2026Excellent quality at this price
Taken 3 capsules daily as suggested. The cognitive clarity is real — I've tried cheaper brands and the difference in quality is noticeable. Medibro seems to use a proper fruiting body extract.
- ★★★★☆Emma K.19/04/2026Subtle but real improvement
It took about 3 weeks to notice anything, but the effects have built up nicely. I feel more focused and less prone to afternoon energy crashes. Good quality product.
- ★★★★☆Grant M.17/04/2026Subtle but consistent cognitive boost
Nothing dramatic but consistently notice better focus and mental clarity on days I take it versus days I miss. That is the most honest review I can write. Properly extracted, clean product.
- ★★★★★Rhys T.12/04/2026The best nootropic I've tried
I've experimented with various nootropics over the years. Lion's mane is the only one that's shown genuinely measurable effects for me — better sustained focus and reduced mental fatigue.
- ★★★★★Matt C.09/04/2026Sharper thinking, less brain fog
I work in finance and tried lion's mane after reading about the NGF research. Three weeks in and I can process complex information faster and feel mentally clearer throughout the day.
- ★★★★★David L.Verified buyer23/03/2026Focus and memory improved
40s and starting to notice cognitive decline. Added lion's mane 1000mg daily. 3 months in and focus during complex work is noticeably sharper. Word-finding is easier. The mycelium extract quality matters — this is properly extracted.
- ★★★★★Anya P.17/03/2026Noticeable cognitive difference
I'm a PhD student and started taking this during my thesis writing. Within two weeks I noticed sharper focus and less mental fatigue during long study sessions. This dose (1000mg) seems to be the sweet spot.
- ★★★★★Louise B.Verified buyer14/03/2026Nerve regeneration benefit too
Peripheral neuropathy in feet from type 2 diabetes. Neurologist mentioned that lion mane NGF stimulation might support nerve health. After 4 months the tingling in my feet has noticeably reduced. Unexpected benefit.
- ★★★★☆Rachel M.09/03/2026Good cognitive support
PhD student under heavy cognitive load. Lion's mane has helped maintain focus during extended study sessions. Subtle but consistent effect. Quality extract, properly dosed.
- ★★★★★James W.05/03/2026Three months in — still impressed
I rotate my supplements every few months to avoid tolerance. Lion's mane is the one I keep coming back to because the effects are consistently real. Top quality product.
- ★★★★★Alex K.Verified buyer03/03/2026Focus like I had in my 30s
At 48 the mental sharpness of my 30s felt like a distant memory. Added lion mane alongside my existing stack. 10 weeks in and the difference is significant. Clearer thinking, better recall, faster processing.
- ★★★★★Dr. W. F.Verified buyer01/02/2026NGF stimulation confirmed by neurologist
Consultant neurologist confirmed that lion mane nerve growth factor stimulation is supported by clinical evidence. After 12 weeks on 1000mg daily my cognitive test scores improved measurably. The mycelium extract quality is critical.
- ★★★★★Wendy A.Verified buyer19/01/2026Depression and cognition both improved
Post-menopausal depression affecting cognition. Psychiatrist open to adjunct supplements. Lion mane at 1000mg has improved both mood and cognitive function. The BDNF-stimulating mechanism is plausible and well-researched.
- ★★★★★Professor J.H.Verified buyer06/12/2025Remarkable cognitive effects
Cognitive neuroscience researcher. The beta-glucan content and NGF (nerve growth factor) stimulation from lion's mane is genuinely exciting. After 12 weeks on 1g daily my subjective cognitive clarity is improved. The research is promising.
- ★★★★★Sarah P.Verified buyer26/11/2025Alzheimers prevention protocol
Family history of early-onset Alzheimers. Geriatrician included lion mane in my prevention protocol. 6 months in and cognitive clarity is excellent. The neuroprotective mechanisms are increasingly well-supported.
- ★★★★★Colin T.Verified buyer11/11/2025Anxiety reduction surprise benefit
Expected cognitive benefits but also noticed anxiety reduction. Research indicates lion's mane may modulate BDNF and support mood regulation. The dual cognitive and anxiolytic benefit was unexpected but welcome.
