Score breakdown
Score Breakdown
The product uses fruiting body material for both Lion's Mane (Hericium erinaceus) and Reishi (Ganoderma lucidum), which scores the maximum 4 points for source type. The beta-glucan percentage is not publicly disclosed, so no points can be awarded for that dimension. The extraction method is not stated, scoring 0; this is particularly relevant for Reishi, where dual extraction is the established standard for triterpene content. Total mushroom content is 500mg per serving, which sits at the lower boundary of the 500–999mg band and scores 1 point for dose adequacy.
The brand clearly states that the product uses fruiting body material, earning full marks for source disclosure. However, the beta-glucan percentage, extraction method, and country of origin are not publicly disclosed, and no certificate of analysis is available. Three or more core fields are missing, triggering a transparency penalty of -1. The raw transparency score of 2 points, after the penalty, normalises to 2.22 out of 10.
Cost per 100mg beta-glucan cannot be calculated because the beta-glucan percentage is not publicly disclosed. This score reflects price per serving only. At £0.7663 per serving, the product falls in the £0.71–£1.20 range against the category benchmark, giving a base score of 2.0. One additional point would have been deducted for the absence of beta-glucan data, but the base score is already at the floor for this band.
The brand has a Trustpilot score of 4.1 from 210 reviews, which scores 4 points (4.0–4.4 stars with fewer than 500 reviews). Third-party testing is not publicly disclosed and no COA is available, scoring 0 points for that dimension. The product is not organically certified, scoring 0 points for certification.
Subscription purchasing is not available; the product is sold on a one-off basis only, which scores a neutral 2 points. The brand offers a 30-day return policy, scoring the maximum 3 points for that dimension. The product ships to the UK but is not identified as a UK-based brand, scoring 2 points for availability.

How Feel Güd could improve this score
Path to improvement
+0.2 points to reach Partial Disclosure
+0.2
pts needed
- 1
Publish a beta-glucan percentage for each species, verified by a third-party COA — this would add approximately 3–4 points to ingredient quality score and up to 2 points to transparency score.
- 2
Make a COA from an ISO 17025-accredited laboratory publicly available, covering beta-glucans, heavy metals, and microbial contamination — this would add up to 3 points to transparency score and 3 points to trust score.
- 3
Disclose the extraction method used for Lion's Mane and Reishi — this would add 1–2 points to ingredient quality score and 1 point to transparency score.
- 4
Disclose the country of origin for the mushroom material — this would add 1 point to transparency score and help resolve the missing data penalty.
- 5
Publish per-species dosage breakdown for Lion's Mane and Reishi — this would improve transparency and allow more informed purchase decisions.
