Are mushroom gummies a scam? An honest answer from a brand that sells them
Are mushroom gummies a scam? What does the evidence actually say?
Not a scam, but often oversold. The research on functional mushrooms is early: mostly lab and animal work, plus a small number of short human trials on single ingredients. Studies on one ingredient don't prove a finished gummy works, and there is no good evidence that mushroom gummies treat menopause symptoms, ADHD or anything else. So be wary of any brand that implies they do, or presents them as an alternative to medical treatment such as HRT. A fair way to see them: a food supplement with a long history of traditional use, an evidence base that is still developing, and labels you should be able to check line by line.
What the evidence does and doesn't support
| Claim you might see | Where the evidence stands | Our position |
|---|---|---|
| "Boosts focus and memory" | A few small, short human trials on Lion's Mane alone, with mixed results. Nothing on finished gummies. | We don't claim it. We use the authorised vitamin claims that apply to what's in the pack. |
| "Helps with menopause" | Very little: one small study, no clear effect. | We make no menopause claims, and won't. |
| "Helps ADHD" | No evidence. | We make no ADHD claims, and won't. |
| "Alternative to HRT or medication" | No evidence, and potentially dangerous advice. | Never. Talk to your GP. |
| "Reduces stress / deep sleep" | Not an authorised UK health claim for mushrooms. | We don't use it for the mushrooms. Any claim we make is on the approved list for a named vitamin or mineral. |
| "Clinically proven" | Rarely true of a finished product. | Our products haven't been tested as finished products in trials yet. We plan to fund research in 2027. |
Five checks before you buy any mushroom gummy
| Check | What good looks like | Red flag |
|---|---|---|
| Dose | mg of each mushroom per serving on the label | Proprietary blend with no amounts |
| Material | Says whether it's fruiting body or mycelium, and the extract ratio | Just "mushroom complex" |
| Testing | Lab reports published for each batch | Nothing published |
| Sugar | Sugar per serving stated, ideally low | Tasty, but mostly sugar |
| Claims | Authorised wording only, tied to a named vitamin or mineral | Treats, cures, replaces medicine, or "clinically proven" |
The trade-offs
Mushroom gummies
- Easy to take, and you're more likely to keep it up
- Can carry real, declared doses
- Mushrooms have a long history as food
- Little research on finished gummies
- Often oversold
- Usually less mushroom per pound than capsules or powder
Grass & Co. FOCUS MAX gummies
- 5,000mg Lion's Mane + 2,000mg Ginseng (dry herb equivalent) per two gummies
- Zero sugar, Vegan Society registered
- Batch lab reports published
- Not tested as a finished product in trials yet
- Contains soy
- Our capsules and powder give more Lion's Mane for the money
Mushroom gummies aren't a scam, but much of the marketing goes further than the science. Buy one because you're curious about a traditional ingredient and the label is honest, not because an ad promised it would fix something. And if a brand tells you to swap a gummy for your medication, walk away.
We can't point to a trial on our own finished gummies, because there isn't one yet. Like everyone in this category, we rely on research on single ingredients, and we say so. We plan to fund research in 2027 and will publish what we find, including if it doesn't flatter us. Until then, all we can offer is declared doses, published lab reports and only the claims we're allowed to make.

Questions people ask
- Are mushroom gummies a scam?
- Not usually, but they're often oversold. The ingredients have a long history of traditional use and some early research, but there's little evidence for finished gummy products, and none for treating menopause symptoms or ADHD.
- Do mushroom gummies help with menopause?
- There's very little evidence: one small study, with no clear effect. Grass & Co. makes no menopause claims. If menopause symptoms are affecting you, speak to your GP, especially about HRT.
- Can mushroom gummies replace HRT?
- No. No food supplement should be presented as an alternative to HRT or any prescribed treatment. Speak to your GP.
- Do mushroom gummies help ADHD?
- There's no evidence that they do, and Grass & Co. makes no ADHD claims.
- What did the BBC say about mushroom gummies?
- A BBC Radio 4 programme on the science behind trending products looked at mushroom gummies. It found limited evidence for finished products, criticised marketing that framed gummies as an alternative to HRT, and concluded that more research is needed. We agree on all three points.
- Is Grass & Co. funding research?
- Yes. We plan to fund research in 2027 and will publish the results, whatever they show.
- Isn't it just placebo?
- Placebo responses are strong in this area, which is exactly why properly controlled trials matter. Until there are more of them, any brand claiming certainty is going beyond the evidence.
