Score breakdown
Score Breakdown
The product uses Lion's Mane fruiting body (Hericium erinaceus), which scores the maximum 4 points for source type. The extraction method is hot water extraction, which is the established standard for Lion's Mane and scores 1 point. The beta-glucan percentage is not publicly disclosed, so no points are awarded for that sub-dimension. The serving delivers 1,000mg of mushroom extract, meeting the threshold for the maximum dose adequacy score of 2 points.
The brand publicly states the source type (fruiting body) and the extraction method (water extract), earning full marks for those fields. No COA is publicly available, and the beta-glucan percentage is not publicly disclosed, scoring 0 for both those sub-dimensions. The country of origin is not publicly disclosed. With three or more core fields missing, a transparency penalty of -1 has been applied by the platform.
The beta-glucan percentage is not publicly disclosed, so the platform has calculated beta_glucans_per_serving_mg as null and cost per 100mg beta-glucan cannot be calculated. The price per serving is £0.67, which falls in the £0.41–£0.70 bracket under the fallback price-per-serving method, giving a base score of 3.0. One point has been deducted because the cost per 100mg beta-glucan cannot be calculated due to the beta-glucan percentage not being publicly disclosed, giving a final value score of 2.0.
The brand has a Trustpilot score of 4.5 stars from 50 reviews, which meets the star threshold but falls below the 500-review count required for the top band, scoring 3 points. Third-party testing is not publicly disclosed and no COA is available, scoring 0 for that sub-dimension. The product is not organically certified, scoring 0 for organic certification.
No subscription option is publicly available, which scores a neutral 2 points. No return policy is publicly disclosed, scoring 0 for that sub-dimension. The product ships to the UK, scoring 2 points for UK availability as it appears to be an international brand shipping to the UK.

Publish a beta-glucan percentage from a named third-party laboratory — this would add up to 6 points across the ingredient quality and transparency dimensions.
- 2
Make a COA publicly available, covering beta-glucans, heavy metals, and microbial testing from an ISO 17025-accredited lab — this would add up to 3 points to the transparency score and up to 3 points to the trust score.
