Score breakdown

Score Breakdown

Ingredient Quality5.0

The product uses fruiting bodies of Lion's Mane (Hericium erinaceus), Chaga (Inonotus obliquus), and Cordyceps militaris, scoring the maximum 4 points for source type. The total mushroom content is 3,000mg per serving, which meets the threshold for 2 points on dose adequacy. Beta-glucan percentage is not publicly disclosed, so it scores 0 on that sub-dimension. The extraction method is not publicly disclosed despite extraction being stated as a feature, so it also scores 0; for Chaga in particular, dual extraction is considered important to access both beta-glucans and triterpenes.

Transparency2.2

The brand publicly states that fruiting bodies are used and that an extraction process is applied, earning points for source and extraction disclosure. However, no COA is publicly available, beta-glucan percentage is not publicly disclosed, and the country of origin is not stated. Three or more core fields are missing, so the platform has applied a transparency penalty of -1 to the raw transparency score.

Value2.0

The platform calculated beta_glucans_per_serving_mg as null and cost_per_100mg_beta_glucan as null, because the beta-glucan percentage is not publicly disclosed. The price per serving is £1.30 (using the subscription price of £33.15 for 30 servings, which reflects a 15% saving meeting the threshold to use the subscription price). Because cost per 100mg beta-glucan cannot be calculated, the score is based on price per serving against the category benchmark; at £1.10 per serving on subscription, this falls in the £0.71–£1.20 range, giving a base score of 2.0, with 1 point already deducted to reflect the absence of beta-glucan disclosure.

Trust5.0

The brand holds a Trustpilot score of 4.5 from 10,045 reviews, meeting the criteria for 5 points. Third-party testing is not publicly disclosed and no COA is available, scoring 0 on that sub-dimension. The product is not stated to be organically certified, and no certification bodies are listed.

How Spacegoods could improve this score

Path to improvement

+0.2 points to reach Partial Disclosure

+0.2

pts needed

  • 1

    Publish beta-glucan percentage per serving, verified by a third-party laboratory — this would add up to 4 points to the ingredient quality score and 2 points to the transparency score.

  • 2

    Make a full-panel COA publicly available (covering beta-glucans, heavy metals, and microbial contamination from an ISO 17025-accredited lab) — this would add up to 3 points to the transparency score and 3 points to the trust score.

  • 3

    Disclose the extraction method used for each species — this would add up to 2 points to the ingredient quality score.

  • 4

    State the country of origin for the mushroom ingredients — this would add 1 point to the transparency score.

  • 5

    Publish per-species dosage breakdown — this would provide consumers with more complete information and support a more informed purchase decision.
