How Erbology could improve this score
Path to improvement
+0.4 points to reach Well Documented
+0.4
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
Disclose the extraction method used (for example, hot water extraction) — this would add 1 point to the ingredient quality score and 1 point to the transparency score.
- 3
Have the beta-glucan percentage verified by a third-party laboratory and reference the lab name publicly — this would raise score_beta_glucan_disclosed from 1 to 2 points.
- 4
Name the organic certification body — this would raise score_organic from 1 to 2 points.
- 5
Publish clear subscription cancellation terms — this would raise score_subscription_flex from 3 to 4 points.
