Score breakdown
Score Breakdown
The product uses Agaricus blazei fruiting body, which scores the maximum 4 points for source type. The brand states a beta-glucan content of 25%, placing it in the 20–29% band and scoring 2 out of 4; this figure is brand-stated rather than third-party verified. The extraction method is not publicly disclosed, scoring 0 out of 2. The serving delivers 1,000mg of mushroom extract, meeting the threshold for the maximum dose adequacy score of 2.
The brand states the source type (fruiting body) and country of origin (Europe), and discloses a beta-glucan percentage, but that figure is brand-stated rather than independently verified. No COA is publicly available, scoring 0 out of 3 for that sub-dimension. The extraction method is not publicly disclosed, and no COA panel type can be assessed. With fewer than three core fields missing, no transparency penalty applies.
The beta-glucan percentage is brand-stated at 25%, giving 250mg of beta-glucans per 1,000mg serving. At a price per serving of £0.52 (one-off price; the subscription saving of 10% is below the 15% threshold required to use the subscription price), the cost per 100mg beta-glucan is £0.21, placing the product in the good-value tier and scoring 7.96 out of 10.
The brand holds a Trustpilot score of 4.6 from 1,362 reviews, meeting the threshold for the maximum score of 5. The brand states it uses third-party testing but does not make a COA publicly available, scoring 1 out of 3 for third-party testing. Organic certification is claimed but no certification body is named, scoring 1 out of 2.
A subscription is available with no lock-in; however, the cancellation policy is not clearly described, scoring 3 out of 4 for subscription flexibility. The return policy is 21 days, placing it in the 14–29 day band and scoring 2 out of 3. The brand operates in the UK and ships to the UK, scoring the maximum 3 out of 3 for UK availability.

How Erbology could improve this score
Path to improvement
+1.6 points to reach Fully Verified
+1.6
pts needed
- 1
Publish a COA from an ISO 17025-accredited laboratory covering beta-glucans, heavy metals, and microbial contamination — a full-panel COA would add up to 3 points to the transparency score.
- 2
Disclose the extraction method used (for example, hot water or dual extraction) — this would add 1 point to the ingredient quality score and 1 point to the transparency score.
- 3
Have the beta-glucan percentage verified by a third-party laboratory and publish the result — moving beta-glucan source from brand-stated to third-party COA would add 1 point to the transparency score.
- 4
Name the certification body for the organic claim — this would add 1 point to the trust score.
