## Verdict
Spacegoods mushroom coffee (Rainbow Dust) is the UK's biggest and has the clearest label of any multi-mushroom coffee: 1,000 mg each of fruiting-body lion's mane, cordyceps and chaga, plus 300 mg KSM-66 ashwagandha. But it is a flavoured, sweet-leaning drink rather than a plain coffee, at about £1.63 a serving, and its lab-testing claim has no published COA.
Overall score: 3.7/5 (taste 3.5, ingredients 3.5, transparency 4.5, value 2.5, lab testing 3.5, dosage 4.5)

- You are in the US and want USD pricing and fast shipping

## FAQ
Q: How much caffeine is in Spacegoods Rainbow Dust?
A: It depends on the flavour. Spacegoods lists 80–120 mg of natural caffeine per 8 g serving: the Coffee flavour is at the top of that range at around 120 mg, roughly a regular cup, while the Chocolate and Vanilla Cinnamon versions are closer to 80 mg. A Decaf Coffee flavour is also sold.

Q: How much lion's mane is in Rainbow Dust?
A: 1,000 mg of lion's mane fruiting-body extract per serving, stated on the label alongside 1,000 mg cordyceps and 1,000 mg chaga. That puts lion's mane at the bottom of the 1,000–3,000 mg/day range used in the main human trials, which is more than any of the big US instant blends deliver per cup.

Q: How much does Spacegoods cost per serving?
A: A single 240 g pouch of 30 servings is £49 at the one-time price, or about £1.63 per serving. Subscriptions bring it to roughly £39 per pouch, and the site pushes a discounted starter kit for the first order. USD pricing was not displayed on the US storefront when we checked.

Q: Is Spacegoods mushroom coffee organic?
A: No. Spacegoods does not claim organic certification for Rainbow Dust. It does state that the product is vegan, non-GMO, gluten-free and made in England, and that it is third-party lab tested for heavy metals and allergens, though we did not find a published certificate of analysis.
