Score breakdown
Score Breakdown
The product is described as a blend, but the source type is unclear as no per-source beta-glucan data is disclosed, so score_source_type scores 0 rather than 3. The beta-glucan percentage is not publicly disclosed, so score_beta_glucan_pct scores 0. The extraction method is not publicly disclosed and defaults to whole_powder, scoring 0. Total mushroom weight per serving is also not publicly disclosed, so dose adequacy scores 0.
The brand has a publicly claimed full-panel COA, which scores 3 points for score_coa, though no COA URL is publicly accessible to verify this independently. The beta-glucan percentage is not publicly disclosed, scoring 0 for score_beta_glucan_disclosed. The source type is stated but described only in general terms, scoring 1 for score_source_stated. The extraction method and country of origin are not publicly disclosed, and three or more core fields are missing, applying a penalty of minus 1.
Cost per 100mg beta-glucan cannot be calculated because beta-glucan percentage is not publicly disclosed. The price per serving is £2.63, which is above the category benchmark of £0.60 per serving. This score reflects price per serving only, with 1 point deducted for the absence of beta-glucan data needed to calculate active-unit cost.
The product holds a Trustpilot score of 3.9 from 18,000 reviews, which falls in the 3.5 to 3.9 band and scores 2 points. Third-party testing is stated as true and a full-panel COA is claimed, scoring 3 points. The product holds NSF Certified for Sport and Informed Sport certifications, but these are sport-integrity certifications rather than organic certifications, so score_organic scores 0.
No subscription is available, which scores a neutral 2 points. The return policy is not publicly disclosed, scoring 0. The product ships to the UK but does not appear to be a UK-based brand, scoring 2 points for UK availability.

How AG1 could improve this score
Path to improvement
+1.4 points to reach Partial Disclosure
+1.4
pts needed
- 1
Publish the beta-glucan percentage per species on the product label or website — this would add up to 4 points to the ingredient quality score and 2 points to the transparency score.
- 2
Disclose the total mushroom extract weight per serving — this would add up to 2 points to the ingredient quality score.
- 3
State the extraction method publicly — this would add 1 point to the transparency score and up to 2 points to the ingredient quality score.
- 4
Publish the country of origin for the mushroom ingredients — this would add 1 point to the transparency score and remove the missing-data penalty.
- 5
Publish a publicly accessible COA URL — this would improve transparency score verification and support the existing full-panel COA claim.
