Score breakdown
Score Breakdown
The product uses Turkey Tail fruiting body (Trametes versicolor), which scores the maximum 4 points for source type. Beta-glucan content is 30%, verified by SGS Canada via third-party COA, placing it in the 30–39% band and scoring 3 out of 4. The extraction method is not publicly disclosed, scoring 0. Each serving provides 1,000mg of mushroom extract, meeting the threshold for the maximum dose adequacy score of 2.
The brand discloses source type, beta-glucan percentage verified by a named third-party laboratory (SGS Canada), country of origin (China), and a full-panel COA covering beta-glucans, heavy metals, and microbial contamination. The extraction method is not publicly disclosed, reducing the transparency score. No transparency penalty applies, as fewer than three core fields are missing.
Price per serving is not publicly disclosed, so cost per 100mg beta-glucan cannot be calculated despite beta-glucans per serving being determinable at 300mg. The value score is 0.0 because no price data is available to assess value. If pricing is published in future, value scoring can be completed.
The brand holds a Trustpilot rating of 4.5 stars from 55 reviews, which scores 3 points (high rating but fewer than 500 reviews). Third-party testing is confirmed with a full-panel COA available from SGS Canada, scoring the maximum 3 points. Organic certification is confirmed under both USDA Organic and Quality Assurance International, scoring the maximum 2 points.
Subscription availability and terms are not publicly disclosed, resulting in the neutral score of 2 points applied to products without a confirmed subscription option. No return or money-back policy is publicly stated, scoring 0. The brand is based in Canada and does not ship to the UK, scoring 0 for UK availability.

How Real Mushrooms could improve this score
Path to improvement
+1.8 points to reach Fully Verified
+1.8
pts needed
- 1
Disclose the extraction method (for example, hot water extraction) — this would add up to 1 point to the ingredient quality score.
- 2
Publish retail pricing publicly — this would allow cost per 100mg beta-glucan to be calculated and would unlock a value score above 0.
- 3
State a return or money-back policy — this would add up to 3 points to the consumer experience score.
- 4
Enable UK shipping or name a UK retailer — this would add up to 2–3 points to the consumer experience score.
- 5
Publish subscription terms including cancellation policy — this would add up to 2 additional points to the consumer experience score.
