Score breakdown
Score Breakdown
The brand states fruiting body as the source type for both Lion's Mane (Hericium erinaceus) and Reishi (Ganoderma lucidum), earning the maximum source-type score. The beta-glucan percentage is not publicly disclosed, so no score can be awarded for that sub-dimension. The extraction method is not publicly disclosed, which is a particular gap for Reishi, where dual extraction is the established method for capturing triterpenes. Total mushroom content is 500mg per serving, which falls in the 500–999mg range and earns 1 point for dose adequacy.
The brand states the mushroom source type clearly, earning 2 points for that sub-dimension. However, beta-glucan percentage, extraction method, country of origin, and a COA are all not publicly disclosed, resulting in a transparency penalty of -1 applied by the platform. With three or more core fields missing, the penalty applies and the raw transparency score is further reduced.
The beta-glucan percentage is not publicly disclosed, so beta_glucans_per_serving_mg and cost_per_100mg_beta_glucan cannot be calculated, as confirmed by the platform. Value is assessed on price per serving only, which is £0.77. At this price level, against the category benchmark of £0.60 per serving, the base score is 2.0, with a further 1-point deduction applied because the cost per 100mg beta-glucan cannot be calculated. The final value score is 2.0.
The brand has a Trustpilot rating of 4.6 stars, but from only 18 reviews. Fewer than 50 reviews triggers the neutral rule, so the score is 2 points regardless of the rating. Third-party testing is not publicly disclosed and no COA is available, earning 0 points for that sub-dimension. The product is not stated to be organically certified, so 0 points are awarded for organic certification.
Subscription purchasing is not available; a one-off purchase only earns the neutral 2 points for subscription flexibility. The brand offers a 30-day return policy, which earns the maximum 3 points for that sub-dimension. The product ships to the UK, earning 2 points for UK availability, though it is not confirmed as a UK-based brand.

Score reasoning
Ingredient Quality
The brand states fruiting body as the source type for both Lion's Mane (Hericium erinaceus) and Reishi (Ganoderma lucidum), earning the maximum source-type score. The beta-glucan percentage is not publicly disclosed, so no score can be awarded for that sub-dimension. The extraction method is not publicly disclosed, which is a particular gap for Reishi, where dual extraction is the established method for capturing triterpenes. Total mushroom content is 500mg per serving, which falls in the 500–999mg range and earns 1 point for dose adequacy.
Transparency
The brand states the mushroom source type clearly, earning 2 points for that sub-dimension. However, beta-glucan percentage, extraction method, country of origin, and a COA are all not publicly disclosed, resulting in a transparency penalty of -1 applied by the platform. With three or more core fields missing, the penalty applies and the raw transparency score is further reduced.
Value
The beta-glucan percentage is not publicly disclosed, so beta_glucans_per_serving_mg and cost_per_100mg_beta_glucan cannot be calculated, as confirmed by the platform. Value is assessed on price per serving only, which is £0.77. At this price level, against the category benchmark of £0.60 per serving, the base score is 2.0, with a further 1-point deduction applied because the cost per 100mg beta-glucan cannot be calculated. The final value score is 2.0.
Trust
The brand has a Trustpilot rating of 4.6 stars, but from only 18 reviews. Fewer than 50 reviews triggers the neutral rule, so the score is 2 points regardless of the rating. Third-party testing is not publicly disclosed and no COA is available, earning 0 points for that sub-dimension. The product is not stated to be organically certified, so 0 points are awarded for organic certification.
Consumer Experience
Subscription purchasing is not available; a one-off purchase only earns the neutral 2 points for subscription flexibility. The brand offers a 30-day return policy, which earns the maximum 3 points for that sub-dimension. The product ships to the UK, earning 2 points for UK availability, though it is not confirmed as a UK-based brand.

How Feel Güd could improve this score
Path to improvement
+1.3 points to reach Partial Disclosure
+1.3
pts needed
- 1
Publish a full-panel 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 3 points to the trust score.
- 2
Disclose the beta-glucan percentage of each mushroom extract — this would unlock the cost-per-100mg calculation and potentially add up to 4 points to the ingredient quality score and 2 points to the transparency score.
- 3
State the extraction method used for both Lion's Mane and Reishi — this would add 1 point to the transparency score and up to 2 points to the ingredient quality score.
- 4
Disclose the country of origin for the mushroom material — this would add 1 point to the transparency score and help resolve the missing-data penalty.
- 5
Publish a per-species dosage breakdown showing how the 500mg total is split between Lion's Mane and Reishi — this would improve transparency and allow more accurate disclosure scoring.
