If you’ve ever felt “too much coffee, not enough clarity,” welcome to the functional-beverage era. Spacegoods’ Rainbow Dust sits at the crossroads of coffee culture, mushroom wellness, and dopamine décor—a pink-packaged promise to swap jitters for flow. As someone who lives in the land of rituals (matcha, cacao, walks, sunlight), I’ve been testing Spacegoods for a while and thought it was about time to tell the world about the latest tool in the toolbox.
Transparency: This review includes my genuine experience, plus data from independent sources. I’ve collaborated with Spacegoods. Nothing here is medical advice.
What Is Spacegoods?
London-based Spacegoods makes mushroom + adaptogen blends designed as coffee alternatives (daytime focus) and evening wind-down mixes (sleep/calm). Its hero product Rainbow Dust combines instant coffee with lion’s mane, cordyceps, chaga, ashwagandha, maca, rhodiola, vitamin B5, and caffeine.
Spacegoods raised £2.5 million (≈$3.1M) in seed funding led by Five Seasons Ventures, and is founder-led by Matthew Kelly (ex-Neon Beach). The brand now sells direct-to-consumer, on Amazon, and through UK retailers like Holland & Barrett.
Why People Are Replacing Coffee With Rainbow Dust
Taste & ritual. Rainbow Dust drinks like a luxe hot chocolate or latte; I’ve had it hot with almond/soy milk and iced in summer. The chocolate blend, for example, is around 29 kcal per 8g serving.
Ingredient highlights (with UK-friendly context):
- Lion’s mane mushroom (Hericium erinaceus): UK nootropic forums rave about it. In 2023, a small human trial showed improved performance on a cognitive task and lower stress trends after 28 days.
- Ashwagandha: Widely sold in UK health shops; multiple trials show reduced stress, anxiety, and cortisol.
- Caffeine + L-theanine synergy: well-documented in human studies—better focus, fewer jitters.
Note: Results vary. Evidence is promising, but long-term data and extract quality matter.
The Bigger Trend: Focus Drinks, ADHD Culture & Mushroom Coffee
- ADHD therapeutics market: valued at ~£11–13 billion ($14–16B) in 2023 and forecast to grow steadily.
- Nootropics market: projected to reach £11.5 billion ($14.5B) by 2034.
- Adaptogens market: set to hit £12.8 billion ($16.3B) by 2030.
- Mushroom coffee: forecast growth to ~£3.2 billion ($4B) by 2030–2032.
- TikTok factor: the hashtag #ADHD has tens of billions of views, fuelling awareness and demand for focus-boosting products.
- UK landscape: ADHD assessment waitlists are so long that private prescriptions have surged, creating a two-tier system—consumers are meanwhile turning to daily supplements and functional drinks for support.

My Experience
- Energy arc: smoother than a double-espresso; steady lift after 20–40 minutes. Perfect for writing/editing days.
- Mood support: ashwagandha + theanine (when I stack extra theanine) = calmer calls, less edge.

Recipes I’ve Been Loving
- Iced Rainbow Latte – 1 scoop Rainbow Dust, splash of hot water to dissolve, pour over ice + oat/almond milk.
- Mocha-Protein Shake – espresso shot + Rainbow Dust + chocolate protein powder + plant milk.
- Cacao-Collagen Nightcap – decaf Rainbow Dust + steamed milk + collagen powder, whisk until frothy.
Safety Notes
- Watch your daily caffeine load (Rainbow Dust ~80–120mg per serving depending on flavour).
- Ashwagandha can interact with thyroid/autoimmune medications. If pregnant, breastfeeding, or on medication, consult a clinician.
- Supplements are adjuncts, not treatments. If ADHD impacts daily life, pursue clinical diagnosis and support (NHS or private).
