Why, and what each one means
Mushroom supplements differ most in what is in the capsule. Fruiting-body extracts carry the beta-glucans most research is about, while mycelium grown on grain can be mostly starch, so contents and testing carry the most weight: beta-glucan by a named method, starch and metals, ideally from a lab the maker does not pay. Human evidence is thin: our lion’s mane page counts two small trials, and a 2025 review found five (PubMed (opens in a new tab)). See mushroom basics.
- What is in it 25%
- Fruiting body extract with the beta-glucan content stated. Mycelium grown on grain, which is mostly starch, costs points.
- Independent testing 35%
- Beta-glucan, starch and heavy metal results per batch, published. Independent tests count most.
- Evidence 15%
- Human research for this species and form at this dose, and claims that stay within it.
- Trust 10%
- Highest when the maker names everything, answers questions, and has no recalls, warning letters, Prop 65 notices or lawsuits over safety or labeling. Points come off for unresolved problems and for paid promoters it does not disclose.
- Value 15%
- Price per gram of extract against the others here that pass.
Each product scores every one from 1 to 5, and its rating is the weighted average. We list only products rated 3 or above that break none of our rules.
We avoid
- “Full spectrum” or “mycelium on organic grain” labels that do not report starch.
- Polysaccharide figures with no method named, which can count starch.
- Several mushrooms under one blend total, with no amount for each.
- Claims to treat cancer, anxiety, dementia or any other disease.
