Score breakdown
Score Breakdown
Rainbow Dust discloses individual doses for all three mushroom species on the nutritional label: Lion's Mane 1000 mg (fruiting body 5:1 extract), Cordyceps 1000 mg (fruiting body 4:1 extract), and Chaga 1000 mg (fruiting body 4:1 extract), totalling 3000 mg mushroom extract per serving. Fruiting body is confirmed as the source type, scoring the maximum 4 points. Extraction ratios (5:1 and 4:1 concentration) are stated on the label, indicating a concentrated extract, though the specific extraction technique (hot-water, dual, etc.) is not named. Beta-glucan percentage is not publicly disclosed, so that sub-score remains zero.
The brand states fruiting body as the source type and discloses per-species doses on the nutritional label, earning credit for source type disclosure and dose transparency. Extraction ratios are stated, partially addressing the extraction disclosure gap. No COA is publicly available, beta-glucan percentage is not disclosed, and country of origin is not stated. Two core fields remain undisclosed (COA and beta-glucan percentage), so a transparency penalty applies.
Servings per pack is 30 (stated on the nutritional label), giving a price per serving of Ā£2.23 one-off or Ā£1.67 on subscription. Cost per 100 mg beta-glucan cannot be calculated because beta-glucan percentage is not publicly disclosed. At Ā£2.23 per serving and a total of 3000 mg mushroom extract per serving, price per mg of mushroom extract is competitive, but without beta-glucan data the value score remains limited.
No Trustpilot score or review count is publicly available. Third-party testing is not disclosed and no COA is publicly available. Organic certification is not disclosed and no named certification body is listed.
The subscription is available with no lock-in and a cancel-anytime policy, scoring the maximum 4 points for subscription flexibility. The brand offers a 60-day return policy, scoring 3 points. The product ships to the UK.

Transparency
The brand states fruiting body as the source type and discloses per-species doses on the nutritional label, earning credit for source type disclosure and dose transparency. Extraction ratios are stated, partially addressing the extraction disclosure gap. No COA is publicly available, beta-glucan percentage is not disclosed, and country of origin is not stated. Two core fields remain undisclosed (COA and beta-glucan percentage), so a transparency penalty applies.
Value
Servings per pack is 30 (stated on the nutritional label), giving a price per serving of Ā£2.23 one-off or Ā£1.67 on subscription. Cost per 100 mg beta-glucan cannot be calculated because beta-glucan percentage is not publicly disclosed. At Ā£2.23 per serving and a total of 3000 mg mushroom extract per serving, price per mg of mushroom extract is competitive, but without beta-glucan data the value score remains limited.

How Spacegoods could improve this score
Path to improvement
+1.5 points to reach Partial Disclosure
+1.5
pts needed
- 1
Publish a full-panel COA from an ISO 17025-accredited laboratory covering beta-glucans, heavy metals, and microbial contamination ā this would add up to 5 points across transparency and trust scores.
- 2
Disclose the beta-glucan percentage per serving, ideally verified by a named third-party laboratory ā this would add up to 4 points to the ingredient quality score and 2 points to the transparency score.
- 3
State the specific extraction technique used (e.g. hot-water, dual extraction) for each species ā this would further improve the extraction method sub-score.
- 4
State the country of origin for the mushroom ingredients ā this would add 1 point to the transparency score.

What is Rainbow Dust?
Rainbow Dust is a powdered adaptogen and functional mushroom blend from London-based brand Spacegoods. Each 8 g serving (one tablespoon) mixes with coffee or hot water, delivering three mushroom extracts and four adaptogens in a single daily serving. The product is marketed for focus, energy, and stress support. It is vegan, cruelty-free, and manufactured in England.
With 30 servings per pouch, the one-off price works out at Ā£2.23 per serving (Ā£67 Ć· 30), or Ā£1.67 per serving on subscription (Ā£50 Ć· 30).
Ingredient breakdown
The nutritional label discloses individual doses for all active ingredients ā a transparency positive that most blended adaptogen products avoid.
Mushroom extracts ā 3,000 mg total per serving
| Ingredient | Dose | Extract type |
|---|---|---|
| Lion's Mane (Hericium erinaceus) | 1,000 mg | Fruiting body, 5:1 extract |
| Cordyceps (Cordyceps militaris) | 1,000 mg | Fruiting body, 4:1 extract |
| Chaga (Inonotus obliquus) | 1,000 mg | Fruiting body, 4:1 extract |
All three species use fruiting body rather than mycelium ā the part of the mushroom generally considered to contain higher concentrations of active compounds such as beta-glucans and hericenones. The concentration ratios (5:1 and 4:1) indicate these are standardised extracts. The specific extraction technique (hot-water, dual, ethanol) is not named on the label; this distinction matters most for Chaga, which requires dual extraction to access its key triterpene compounds alongside polysaccharides.
Adaptogens and other actives
| Ingredient | Dose | Notes |
|---|---|---|
| Maca Root | 250 mg | ā |
| Ashwagandha Root | 200 mg | Extract type not specified on label |
| Natural Caffeine (from Coffee) | 80 mg | Roughly equivalent to one small espresso |
| Rhodiola Rosea | 25 mg | Providing 3 mg Salidroside |
| Pantothenic Acid (Vitamin B5) | 6 mg | 100% of EU Reference Intake |
Other ingredients: Cacao powder, Stevia (natural sweetener). No artificial colours.

Are the doses clinically relevant?
- Lion's Mane at 1,000 mg: Within the clinically studied range (500ā3,000 mg daily). The 5:1 concentration ratio indicates meaningful extract density, though without a stated beta-glucan percentage the active compound load cannot be independently verified.
- Cordyceps at 1,000 mg: At the lower end of studied dose ranges (1,000ā3,000 mg daily). The 4:1 concentration partially compensates.
- Chaga at 1,000 mg: Within the broadly studied range (400ā2,000 mg daily).
- Ashwagandha at 200 mg: Below the 300ā600 mg range used in most human trials on cortisol and stress outcomes. Potency per milligram depends on the extract standard (e.g. KSM-66, Sensoril), which is not stated on the label.
- Rhodiola at 25 mg: Typical trial doses are 200ā600 mg root extract. However, the stated 3 mg Salidroside content is within the 1ā4 mg range used in salidroside-standardised studies, partially validating potency.
- Caffeine at 80 mg: A moderate, functional dose ā roughly one small coffee. Below the 200 mg threshold commonly associated with anxiogenic effects.
What the label still does not disclose
Despite full per-ingredient dose disclosure, four data points remain missing that affect the Cogniscore rating:
- Beta-glucan percentage: The most important quality marker for mushroom extracts. Without it, extract quality and value for money cannot be independently verified.
- Certificate of Analysis (COA): No third-party lab report is publicly linked. A COA from an ISO 17025-accredited laboratory would verify beta-glucan content and confirm absence of heavy metals and contaminants.
- Country of origin: The source region for the mushroom raw material (commonly China, US, or Europe) is not disclosed, limiting traceability assessment.
- Specific extraction method: The stated 5:1 and 4:1 ratios indicate concentration but not whether hot-water, ethanol, or dual extraction was used ā a distinction that determines which compound classes (polysaccharides vs. triterpenes) are preserved.
