How DIRTEA could improve this score
Path to improvement
+1.5 points to reach Well Documented
+1.5
pts needed
- 1
Publish beta-glucan percentage on product pages or packaging — this would add up to 4 points to the ingredient quality score and 2 points to the transparency score.
- 2
Make a certificate of analysis publicly available — a full-panel COA from an ISO 17025-accredited laboratory would add 3 points to the transparency score and 2 additional points to the third-party testing score.
- 3
Disclose total mushroom extract per serving in milligrams — this would allow dose adequacy to be assessed and cost per 100mg beta-glucan to be calculated, improving both ingredient quality and value scores.
- 4
Name the organic certification body — this would add 1 point to the trust score, moving score_organic from 1 to 2.
- 5
Have beta-glucan percentage verified by a named third-party laboratory and publish results — this would add 1 point to the transparency score via score_beta_glucan_disclosed.
