Score breakdown
Score Breakdown
The product uses Chaga fruiting body, which scores the maximum 4 points for source type. The extraction method is whole powder, which scores 0 as no extraction process is applied. The third-party COA discloses a beta-glucan percentage of 7%, which falls below 10% and scores 0 for beta-glucan concentration. The serving size is 1,000mg, which scores the maximum 2 points for dose adequacy.
The brand publicly states the source type, extraction method, and country of origin (Europe), and discloses a beta-glucan percentage verified by a third-party COA. The COA covers beta-glucan only and does not appear to include heavy metals or microbial testing, scoring 2 rather than 3 for that field. No COA URL is publicly accessible, and the name of the testing laboratory is not publicly disclosed. Three or fewer core fields are missing, so no transparency penalty applies.
The beta-glucan percentage is publicly disclosed at 7%, giving 70mg of beta-glucans per 1,000mg serving. At a price of £0.3998 per serving, the cost per 100mg beta-glucan is £0.5711, which sits in the £0.41–£0.75 average band. The category median is £0.3967 per 100mg, so this product sits above the median cost per active unit.
The product holds a Trustpilot score of 4.4 from 890 reviews, scoring 4 points. Third-party testing is confirmed and a COA is available, though the panel is beta-glucan only rather than a full panel, scoring 2 points. The product holds two named organic certifications, EU Organic (CZ-BIO-02) and COSMOS Organic, scoring the maximum 2 points.
Subscription purchase is not available, which scores a neutral 2 points. The return policy is 30 days, scoring the maximum 3 points. The product ships to the UK but is not a UK-based brand, scoring 2 points for international shipping availability.

The third-party COA discloses a beta-glucan percentage of 7%, which falls below 10% and scores 0 for beta-glucan concentration. The serving size is 1,000mg, which scores the maximum 2 points for dose adequacy.
Transparency
The brand publicly states the source type, extraction method, and country of origin (Europe), and discloses a beta-glucan percentage verified by a third-party COA. The COA covers beta-glucan only and does not appear to include heavy metals or microbial testing, scoring 2 rather than 3 for that field. No COA URL is publicly accessible, and the name of the testing laboratory is not publicly disclosed. Three or fewer core fields are missing, so no transparency penalty applies.
Value
The beta-glucan percentage is publicly disclosed at 7%, giving 70mg of beta-glucans per 1,000mg serving. At a price of £0.3998 per serving, the cost per 100mg beta-glucan is £0.5711, which sits in the £0.41–£0.75 average band. The category median is £0.3967 per 100mg, so this product sits above the median cost per active unit.

How Erbology could improve this score
Path to improvement
+1.9 points to reach Fully Verified
+1.9
pts needed
- 1
Publish a publicly accessible COA URL covering heavy metals and microbial contamination alongside the beta-glucan result — this would raise score_coa from 2 to 3 and add approximately 1.1 points to the transparency score.
- 2
Disclose the name of the third-party laboratory that issued the beta-glucan COA — this would increase data confidence and support the beta_glucan_source claim.
- 3
Upgrade from whole powder to a hot water or dual extract — this would add up to 2 points to score_extraction_method and score_beta_glucan_pct, and is particularly relevant for Chaga where triterpene extraction requires ethanol.

Overall Score
This score reflects the completeness of publicly available information about this product, not its quality or efficacy.
Score Breakdown
The product uses chaga fruiting body, which scores the maximum for source type. The serving size of 1,000mg also scores the maximum for dose adequacy. The extraction method is whole powder, meaning no extraction process is applied, which scores zero in this dimension. The disclosed beta-glucan content of 7% falls below the 10% threshold, so it scores zero for beta-glucan concentration.
Erbology publicly states the source type, extraction method, and country of origin (Europe), and discloses a beta-glucan percentage backed by a third-party certificate of analysis. The COA covers beta-glucan only and does not appear to include heavy metals or microbial testing, which limits the score for that field. No COA URL is publicly accessible, and the name of the testing laboratory is not publicly disclosed.
At 7% beta-glucan concentration, each 1,000mg serving delivers 70mg of beta-glucans. The cost per 100mg of beta-glucan is £0.57, which sits in the average band (£0.41–£0.75). The category median is £0.40 per 100mg, so this product sits above the median cost per active unit, which is reflected in the value score.
Erbology holds a Trustpilot score of 4.4 from 890 reviews. Third-party testing is confirmed and a certificate of analysis is available, though the panel covers beta-glucan only rather than a full panel. The product holds two named organic certifications, EU Organic (CZ-BIO-02) and COSMOS Organic, which score the maximum for this field.
A subscription purchase option is not available, which scores a neutral two points. The return policy is 30 days, scoring the maximum for that field. The product ships to the UK, though Erbology is not a UK-based brand, which scores two points for international shipping availability.

How Erbology Could Improve This Score
Publishing a publicly accessible COA URL that covers heavy metals and microbial contamination alongside the beta-glucan result would raise the COA field score from 2 to 3, adding approximately 1.1 points to the transparency score.
Disclosing the name of the third-party laboratory that issued the beta-glucan COA would increase data confidence and support the beta-glucan source claim.
