How much caffeine is in Space Goods Rainbow Dust?

Rainbow Dust contains approximately 80mg of natural caffeine per serving, derived from natural coffee extract. This is roughly equivalent to one small cup of coffee — enough to feel alert without the spike-and-crash typical of heavily caffeinated drinks.

Brand Overview

The Brand That Made Mushrooms Mainstream in the UK

Matthew Kelly founded Space Goods after a period of burnout and poor mental health. He noticed that while functional mushrooms were well-known in Asia and the US wellness market, the UK had almost nothing — no brands making them accessible, tasty, or daily-ritual worthy. So he built one. Working with a nutrition lab in Surrey, he spent five months developing Rainbow Dust before launching in April 2022. Within a year, the brand had taken over 30,000 orders and generated £1.4M in revenue. By year two, it had crossed £12M. Space Goods now sits alongside the biggest names in the UK functional wellness space — and it got there on the strength of one genuinely good product.

3 Functional Mushrooms

Lion's Mane, Cordyceps and Chaga — each dosed at a credible 1,000mg per serving, not just dusted in as window dressing.

🧠

Science-Led Formula

KSM-66 Ashwagandha (the most studied form on the market), Maca Root, Rhodiola Rosea and 80mg natural caffeine — not just trendy labels.

☕

Coffee Without the Crash

Real Space Goods Customer Reviews

What customers across the UK, US and beyond say about Rainbow Dust and the Space Goods lineup.

★★★★★

"I was deeply sceptical about mushroom coffee — sounds ridiculous, right? But I've been using Rainbow Dust for three months now and it genuinely replaced my morning espresso. The focus is real, there's no jitter and no 11am slump. I'm actually more productive and my sleep is better because I'm not overcaffeinating. It tastes like a rich hot chocolate. Completely converted."

★★★★★

"I ordered the Starter Kit as a try-before-you-commit option and I'm so glad I did. The chocolate flavour is genuinely delicious — I look forward to making it every morning. Four weeks in and my brain fog has lifted noticeably. I also started Astro Dust at night and I'm sleeping heavier. Couldn't ask for more from a supplement brand that actually delivers."

★★★★☆

"Really impressed with the ingredient transparency — proper doses of Lion's Mane and Ashwagandha, not just trace amounts. Taste is great (went for the Coffee flavour). Would be five stars but I think the subscription management could be smoother — had to email support to pause mine. They sorted it within a day but ideally you'd do it on the website. Product itself is excellent though."

FAQ

Space Goods — Frequently Asked Questions

Everything you need to know before trying Rainbow Dust or the full Space Goods range.

What is Space Goods Rainbow Dust and what does it do? +

Rainbow Dust is a functional mushroom and adaptogen powder that you mix with hot water or milk to create a warming, energising drink — similar to a hot chocolate or coffee alternative. Each serving contains 1,000mg Lion's Mane (for focus and cognitive function), 1,000mg Cordyceps (for natural energy and endurance), 1,000mg Chaga (for immune support and antioxidant protection), KSM-66 Ashwagandha (for stress resilience), Maca Root, Rhodiola Rosea, 80mg natural caffeine and Vitamin B5. The goal is to give you clean, sustained energy and mental clarity without the jitters or crash associated with regular coffee.

Does Space Goods Rainbow Dust actually work? +

The honest answer is: it depends on your baseline and expectations. The formula contains real, credible doses of clinically studied ingredients — Lion's Mane is backed by human trials showing improvements in mild cognitive impairment; KSM-66 Ashwagandha has robust evidence for cortisol reduction and stress; Rhodiola has strong data for mental fatigue. The 80mg caffeine will deliver alertness reliably. Many customers report genuine improvements in focus, energy steadiness and morning mood within 2–4 weeks. Results vary between individuals, and those expecting instant dramatic effects may be disappointed — these are adaptogens, not stimulants, and they work gradually.

How much caffeine is in Rainbow Dust, and is it safe? +

Each serving of Rainbow Dust contains approximately 80mg of natural caffeine from coffee extract — roughly equivalent to one small cup of coffee or a shot of espresso. This is well within safe daily limits for adults (400mg is the generally accepted upper threshold). Because it's paired with calming adaptogens like Ashwagandha and Rhodiola, most users don't experience the anxiety or jitteriness that higher-caffeine products cause. If you're sensitive to caffeine, start with half a serving and assess your response.

What flavours does Rainbow Dust come in? +

Rainbow Dust is currently available in three flavours: Chocolate (the original and most popular — tastes like a rich hot chocolate), Coffee (for those who want a more traditional coffee-adjacent experience), and Vanilla (a lighter, sweeter option). All three share the same core mushroom and adaptogen formula — the only difference is flavour. Most customers prefer the Chocolate for its indulgent taste, while the Coffee flavour appeals to those transitioning away from regular espresso.

Is Space Goods vegan and allergen-free? +

Rainbow Dust, Hydro Dust and Astro Dust are fully vegan, gluten-free and free from artificial colours and flavours. Glow Dust is the exception — it contains hydrolysed bovine collagen and is therefore not vegan. It is suitable for pescatarians and omnivores. If you have specific allergen concerns, always check the most current ingredient list on the product page before ordering, as formulations can evolve.

How do I use Space Goods Rainbow Dust? +

Add one scoop (approximately 8g) to 200–250ml of hot water or warm milk (oat milk works beautifully for a creamier texture). Stir or use a frother for best results. Drink in the morning or early afternoon — it's not recommended in the evening due to the caffeine content (use Astro Dust for your nighttime ritual instead). You can also blend it into smoothies or protein shakes if you prefer a cold option. Start with one serving per day and assess your individual response before increasing.

How do I cancel or pause my Space Goods subscription? +

Space Goods subscription management is handled via their customer portal, accessible through your account on spacegoods.com. You can pause, skip or cancel through the portal. If you encounter any issues, their customer support team can be reached via email or the website chat. Support response times are generally within 24 hours on business days. We recommend managing your subscription at least 48–72 hours before your next scheduled renewal to avoid unwanted charges.

Is Space Goods worth the price compared to other mushroom supplements? +

At $49 per tub (30 servings / $1.63 per serving) or $39 on subscription ($1.30/serving), Rainbow Dust is at the mid-to-premium end of the mushroom supplement market. Compared to competitors, you're getting a multi-ingredient formula (not a single-mushroom product) with credible doses, a high-quality adaptogen stack and a genuinely great-tasting product. If you account for what you might spend on a morning coffee shop habit, Rainbow Dust often comes out cheaper while adding functional benefits. The subscription pricing makes it particularly strong value.
