What's Actually in Rainbow Dust
Rainbow Dust, the brand's flagship blend, combines natural caffeine from coffee (80–120mg per serving, roughly in line with a single espresso shot) with Lion's Mane (1000mg), Cordyceps Sinensis (1000mg) and Chaga (1000mg) mushroom extracts, plus KSM-66 Ashwagandha (300mg), Maca Root (250mg) and vitamin B5. The pitch is that the mushrooms and adaptogens offset the jittery peak-and-crash pattern of coffee on its own, rather than replacing the caffeine entirely — this isn't a decaf or caffeine-free product.
The Rest of the Range
Beyond Rainbow Dust, Spacegoods sells Matcha Dust (a matcha-and-adaptogen blend for a lower-caffeine option than coffee), Astro Dust (formulated for evening use rather than morning energy), and Hydro Dust (an electrolyte blend unrelated to the mushroom-coffee line, aimed at hydration rather than focus). Each is sold as its own 30-serving pouch, so they function as separate products to choose between rather than a single system you buy all of at once.
Manufacturing and Testing Claims
Spacegoods states its products are made in the UK, third-party tested, non-GMO and formulated to be vegan. These are the brand's own stated production standards rather than a specific certification body named on the packaging, but 'made in the UK' combined with third-party testing is a more concrete claim than a lot of supplement brands make about where and how a product is actually produced.
Pricing and Bundles
A single 30-serving bag of Rainbow Dust runs around £29. Multi-bag bundles bring the per-bag price down for regular users — a two-bag bundle and a four-bag bundle are both available — and bundles typically include extras like a travel mug, a frother and a spoon rather than just more product. Buying a single bag first is the lower-commitment way to try the blend before deciding whether the flavor and effect are worth repeating.
The Benefit Claims Worth Knowing
Spacegoods cites its own figures — for example, that the large majority of surveyed users felt a focus benefit from Rainbow Dust. That's a brand-reported survey result rather than an independently audited clinical figure. The individual ingredients (Lion's Mane, Cordyceps, Chaga, ashwagandha) each have their own separate body of research behind them as supplements, but the specific combined effect of this blend hasn't been independently tested as a single formula by us.
Who It Suits
Spacegoods fits coffee drinkers who want to keep the caffeine but are looking to soften the crash with added mushrooms and adaptogens, and who are comfortable ordering from a UK storefront in pounds. Matcha Dust suits anyone wanting a lower-caffeine version of the same idea, and Astro Dust suits an evening routine rather than a morning one. It fits less well if you're looking for a completely caffeine-free option, since only Hydro Dust in the range is caffeine-free by design.

Does Rainbow Dust still contain caffeine?
Yes — around 80–120mg per serving from real coffee, roughly equivalent to a single espresso shot. It's designed to soften the crash, not remove the caffeine.
What's the difference between Rainbow Dust, Astro Dust and Matcha Dust?
Rainbow Dust is the coffee-and-mushroom blend for daytime energy and focus. Matcha Dust swaps in matcha for a lower-caffeine option. Astro Dust is formulated for evening use rather than energy.
Is anything in the range caffeine-free?
Hydro Dust is the caffeine-free option — an electrolyte hydration blend, separate from the mushroom-coffee line.
Where are Spacegoods products made?
The brand states its products are made in the UK and third-party tested, and formulates them as non-GMO and vegan.
