Score breakdown
Score Breakdown
The product uses chaga sclerotium (fruiting body equivalent), sourced from Finland, and scores 4 for source type. The brand states a beta-glucan percentage of 7%, which falls below the 10% threshold for a positive score, so score_beta_glucan_pct is 0. The extraction method is whole powder, which scores 0. Total mushroom content per serving is 1,000mg, meeting the threshold for a full dose adequacy score of 2.
The brand publicly discloses the mushroom source type, country of origin (Finland), and that the product is whole powder. Beta-glucan percentage is brand-stated at 7% but is not publicly verified by a third party, scoring 1 for score_beta_glucan_disclosed. No COA is publicly available, so score_coa is 0. With fewer than three core fields missing, no transparency penalty applies.
The beta-glucan percentage is brand-stated at 7%, giving 70mg of beta-glucans per 1,000mg serving. The cost per 100mg beta-glucan is £0.74, calculated from a price per serving of £0.52 (one-off price of £25.99 across 50 servings). The subscription saving of 10% falls below the 15% threshold, so the one-off price is used. At £0.74 per 100mg beta-glucan, the product sits in the average-to-high cost tier, producing a value score of 4.04.
The brand holds a Trustpilot score of 4.6 from 1,362 reviews, meeting the threshold for a full score of 5. The brand states third-party testing is conducted, but no COA is publicly available, so score_third_party_testing is 1. Organic certification is claimed, but no certification body is named, so score_organic is 1.
A subscription is available with no stated lock-in; however, the cancellation policy is not explicitly described, so score_subscription_flex is 3. The return policy covers 21 days, placing it in the 14–29 day band and scoring 2. The brand operates in the UK and ships to the UK, scoring 3 for UK availability.

How Erbology could improve this score
Path to improvement
+0.7 points to reach Well Documented
+0.7
pts needed
- 1
Publish a COA from an ISO 17025-accredited laboratory covering beta-glucans, heavy metals, and microbial contamination — this would add up to 3 points to the transparency score and up to 3 points to the trust score.
- 2
Have beta-glucan percentage verified by a third party and disclose the result publicly — this would raise score_beta_glucan_disclosed from 1 to 2 and score_beta_glucan_pct from 0 if the verified figure reaches 10% or above.
- 3
Name the certification body for the organic claim — this would raise score_organic from 1 to 2.
- 4
State the subscription cancellation policy explicitly — this would raise score_subscription_flex from 3 to 4.
