SoulBrew Mushroom & Adaptogen Blend
SoulBrew's Mushroom & Adaptogen Blend contains three species: lion's mane, chaga, and cordyceps. The brand states that fruiting body material is used across all three species, which is the part of the mushroom used in clinical research. The product is priced at Ā£29.99 one-off or Ā£26.99 on subscription, giving a cost of Ā£1.00 per serving. No organic certification is held. Several key composition details are not publicly disclosed, which limits independent assessment of the product's potency.

Overall CogniScore
2.91 / 10
Insufficient Data
The score, which reflects disclosure completeness rather than product quality, is 2.91. SoulBrew earns credit for stating fruiting body use and for strong customer review data, but multiple core composition fields are not publicly disclosed, placing the product in the Insufficient Data band.
Score Breakdown
Ingredient Quality ā 3.33 / 10
SoulBrew states that fruiting body is the mushroom source for all three species, which earns the maximum source-type score. However, the total mushroom content per serving is not publicly disclosed, and no per-species dosage is provided. The extraction method is not publicly disclosed. The beta-glucan percentage is not publicly disclosed, so the potency of the fruiting body material cannot be independently assessed. Both dose adequacy and extraction method score zero as a result.
Transparency ā 1.11 / 10
The brand publicly states fruiting body use, which earns the full source-stated score. Beyond that, no certificate of analysis is publicly available, the beta-glucan percentage is not publicly disclosed, the extraction method is not publicly disclosed, and the country of origin for the mushroom raw materials is not publicly disclosed. Because three or more core fields are missing, a missing-data penalty of minus one point applies.
Value ā 2.00 / 10
Cost per 100mg of beta-glucan cannot be calculated because the beta-glucan percentage is not publicly disclosed. The one-off price per serving is Ā£1.00, which is above the category benchmark of Ā£0.60 per serving. The subscription price of Ā£0.90 per serving does not reach the 15% saving threshold that would qualify for a subscription bonus. A further one-point deduction applies because beta-glucan content is not publicly disclosed.
Trust ā 5.00 / 10
SoulBrew holds a Trustpilot score of 4.8 from 626 reviews, which meets the threshold for the maximum Trustpilot score. Third-party testing is not publicly disclosed and no certificate of analysis is available, so the third-party testing score is zero. The product is not organically certified.
Consumer Experience ā 5.00 / 10
The subscription is available with no lock-in and the cancellation terms appear flexible, earning the maximum subscription flexibility score. The return policy is not publicly disclosed, so the return policy score is zero. The product ships to the UK, earning two points for UK availability.
What Is Not Publicly Disclosed
The following fields are not publicly available and could not be assessed: beta-glucan percentage, extraction method, certificate of analysis, country of origin for mushroom raw materials, total mushroom extract weight per serving, per-species dosage breakdown, third-party beta-glucan verification, and full subscription terms.
How SoulBrew Could Improve Their Score
Publishing the total mushroom extract weight per serving and a per-species breakdown would add up to 2 points to the ingredient quality score. Disclosing the beta-glucan percentage, ideally verified by a third-party certificate of analysis, would add up to 4 points to the ingredient quality score and 2 points to the transparency score. Publishing the extraction method used for each species would add 1 point to the transparency score and up to 2 points to the ingredient quality score. Making a full-panel certificate of analysis publicly available from an ISO 17025-accredited laboratory would add up to 3 points to the transparency score and 3 points to the trust score. Disclosing the country of origin for the mushroom raw materials and clarifying the return policy in days would add 1 point to the transparency score and up to 3 points to the consumer experience score.
