About Me
Hi, I'm Will, the person behind Supermushrooms.
This site started from a fairly ordinary problem. A few years ago I went through a stretch of genuine burnout, bad sleep, foggy afternoons, energy that fell off a cliff by 3pm, the works. I started reading into adaptogens, functional mushrooms and nootropics to see what might actually help, and ended up down a rabbit hole I never really climbed back out of.
What struck me almost immediately was the gap between how supplements are marketed and what the evidence behind them actually says. Product listings would claim near-miraculous effects off the back of a single rodent study, or bury a genuinely well-researched ingredient under so much vague wellness language that it was impossible to tell if it was worth buying. So I started doing the boring part properly: pulling the actual clinical trials, checking whether a product's extract ratio and standardisation percentage matched the dose used in the research, and then reading through hundreds of real buyer reviews to see whether people's lived experience backed any of it up.
That's still the whole method behind every "best supplement" post on this site. I'm not a doctor or a nutritionist, and nothing here is medical advice, I'm just someone who got tired of guessing and decided to check properly instead. Every product is judged on the same things: does the dose match what was actually used in clinical research, is the extract standardised or just raw powder, and what do real customers say once the marketing copy is stripped away.
How the star ratings are calculated
The star rating next to each product isn't decorative and it isn't made up. It starts from that product's real, current Amazon UK customer rating, pulled directly from the listing at the time I write or update the post. From there, I adjust it up or down slightly based on my own evaluation of four things: whether the dose matches what was actually used in the clinical research for that ingredient, whether the extract is standardised to a guaranteed potency or just raw powder, the manufacturing and quality signals (third-party testing, certifications, clean labelling), and value relative to other options in the same post. That adjustment is capped, so a product's published rating can never drift far from what real buyers are actually experiencing, it just accounts for formulation quality that a star rating alone doesn't capture.
Two honest caveats: Amazon's own rating moves over time as new reviews come in, so the number here reflects a snapshot at the time of review rather than a live feed. And because the adjustment is my own judgement, applied consistently using the same four criteria for every product, it's a considered opinion, not an independent lab result.
Outside of supplement research, I spend most of my free time hiking, pottering around a small vegetable garden that mostly grows weeds, and drinking more coffee than is probably wise for someone writing about sleep supplements. I live in the UK, which is also why every product recommended here is something you can actually buy locally, rather than the usual US-only Amazon links that don't ship this side of the Atlantic.
If you've got a supplement you'd like properly looked into, or you think I've got something wrong, I'd genuinely like to hear about it. Supermushrooms is a work in progress, and it gets better every time someone points out where it's falling short.
Supermushrooms is an independent publication. When you buy through a link on this site, I may earn a commission, it doesn't cost you anything extra, and it's never influenced which products end up recommended. See the Advertiser Disclosure for the full picture.
