Score breakdown
Score Breakdown
The mushroom source type is not publicly disclosed, so a score of 0 applies for source type. Beta-glucan percentage is not publicly disclosed and the extraction method is listed as whole powder, which scores 0 for both those sub-dimensions. Total mushroom content per serving is also not publicly disclosed, so dose adequacy cannot be assessed. The product contains Reishi and Shiitake, for which dual extraction would be the preferred method, particularly for Reishi triterpenes, but no such extraction is disclosed.
The brand publishes a full-panel COA, which is the strongest available disclosure for testing and scores 3 points. However, beta-glucan percentage, mushroom source type, and country of origin are not publicly disclosed. The extraction method is stated (whole powder), but four of the five core transparency fields are missing or unspecified, triggering a penalty of minus 1 point.
Cost per 100mg beta-glucan cannot be calculated because beta-glucan percentage is not publicly disclosed. Price per serving is Ā£2.63, which is above the Ā£1.20 per serving threshold and scores 1.0 on the price-per-serving fallback scale, with a further deduction of 1 point applied because beta-glucan percentage is absent, giving a final value score of 2.0. This score reflects price per serving only and does not account for active ingredient concentration.
The brand holds a Trustpilot score of 3.9 from 18,000 reviews, which scores 4 points. Third-party testing is confirmed with a publicly available full-panel COA, scoring 3 points. The product holds NSF Certified for Sport and Informed Sport certifications, though neither constitutes organic certification, so the organic sub-dimension scores 0.
A subscription is available with no disclosed lock-in and a cancel-anytime indication, scoring 4 points for subscription flexibility. No return policy duration is publicly disclosed, scoring 0 for that sub-dimension. The product ships to the UK, though it does not appear to be a UK-based brand, scoring 2 points for UK availability.

+1.4
pts needed
- 1
Publish total mushroom extract weight per serving and a per-species breakdown ā this would add up to 2 points to the ingredient quality score.
- 2
Disclose whether fruiting body or mycelium is used for each species ā this would add up to 4 points to the ingredient quality score.
- 3
Publish the beta-glucan percentage per species, verified by a named third-party laboratory ā this would add up to 6 points across ingredient quality and transparency scores.
- 4
Publish the country of origin for mushroom raw materials ā this would add 1 point to the transparency score and remove the missing-data penalty.
- 5
State a return policy or money-back guarantee period publicly ā this would add up to 3 points to the consumer experience score.

Score Summary
2.61 / 10
Band: Insufficient Data
This score reflects the completeness of publicly available information about the mushroom ingredients in AG1 Daily Greens, not the quality of the product itself. Key ingredient data is not publicly disclosed, which limits what the score can assess.
Dimension Breakdown
Ingredient Quality ā 0.83 / 10
The mushroom source type is not publicly disclosed, so no score applies for that dimension. Beta-glucan percentage is not publicly disclosed and the extraction method is listed as whole powder, both of which score zero. Total mushroom content per serving is not publicly disclosed, so dose adequacy cannot be assessed. The product contains Reishi and Shiitake. For Reishi in particular, dual extraction is the method used in clinical research to access triterpenes, but no such extraction is disclosed.
Transparency ā 2.22 / 10
AG1 publishes a full-panel COA, which is the strongest available form of testing disclosure and scores 3 points. Beta-glucan percentage, mushroom source type, and country of origin are not publicly disclosed. The extraction method is stated as whole powder, but four of the five core transparency fields are missing or unspecified, which triggers a penalty of one point.
Value ā 2.00 / 10
Cost per 100mg beta-glucan cannot be calculated because beta-glucan percentage is not publicly disclosed. The price per serving is Ā£2.63, which is above the Ā£1.20 threshold and scores 1.0 on the price-per-serving fallback scale. A further deduction of one point applies because beta-glucan percentage is absent. This value score reflects price per serving only and does not account for active ingredient concentration.
Trust ā 6.00 / 10
AG1 holds a Trustpilot score of 3.9 from 18,000 reviews, scoring 4 points. Third-party testing is confirmed with a publicly available full-panel COA, scoring 3 points. The product holds NSF Certified for Sport and Informed Sport certifications. Neither constitutes organic certification, so the organic sub-dimension scores zero.
Consumer Experience ā 4.00 / 10
A subscription is available with a cancel-anytime indication and no disclosed lock-in period, scoring 4 points for subscription flexibility. No return policy duration is publicly disclosed, scoring zero for that sub-dimension. The product ships to the UK, though AG1 does not appear to be a UK-based brand, scoring 2 points for UK availability.
Data Gaps
The following fields are not publicly disclosed and could not be assessed:
Mushroom source type, beta-glucan percentage, total mushroom content (mg per serving), country of origin for mushroom raw materials, per-species dosage breakdown, beta-glucan verification by a named laboratory, return policy duration, full subscription terms, and a direct URL to the COA.
How AG1 Could Improve Their Score
AG1's overall score is 2.61. The following disclosures would increase it.
Publishing total mushroom extract weight per serving and a per-species breakdown would add up to 2 points to the ingredient quality score.
Disclosing whether fruiting body or mycelium is used for each species would add up to 4 points to the ingredient quality score.
Publishing the beta-glucan percentage per species, verified by a named third-party laboratory, would add up to 6 points across the ingredient quality and transparency scores.
Publishing the country of origin for mushroom raw materials would add 1 point to the transparency score and remove the missing-data penalty.
Stating a return policy or money-back guarantee period publicly would add up to 3 points to the consumer experience score.
