Why is everyone talking about mushroom coffee?

It has gone from health-shop curiosity to one of the most advertised drinks online. In the UK, "mushroom coffee" is searched about 6,600 times a month, and "Spacegoods" itself about 18,100, so more people look up the brand than the category (Google Keyword Planner, October 2026).

Why should you care before buying?

Three reasons. It costs a lot more than ordinary coffee: a Rainbow Dust pouch was £49 one-off or £29 a month in September 2026, about £1 to £1.63 a cup. It still has caffeine, up to 120mg a serving in the Coffee flavour, so it isn't a way off caffeine. And the focus claims rest on thin evidence about individual mushrooms, not on the drink itself.

The short answer: if the idea appeals, the £14 sample pack is the sensible way to find out whether you like it, and Rheal is the cheapest mushroom coffee to compare it with. Every brand here is on our vitamins and supplements page.

Why would you swap your coffee at all?

Coffee is great. But if you’re on cup number three, still can’t concentrate and now feel a bit wired, putting the kettle on again starts to look like a questionable plan.

You wanted to get through the afternoon. Finish the thing you started. Have a bit of energy left afterwards. Somehow, the answer has become more coffee.

I’ve tried coffee, energy drinks and supplements. And I can see how you end up going round in circles: a can instead of a mug, another ingredient to look up, another bottle to remember to take. If caffeine is what’s making you jittery, an energy drink can just deliver more of it. A supplement brings its own homework about ingredients and doses. Neither automatically gives you the afternoon you were hoping for.

Then there’s Spacegoods, offering a bright pink pouch of mushrooms called Rainbow Dust. Which is certainly a more entertaining suggestion than “have another coffee”.

The promise is tempting: focus, energy and calm, in something you can stir into a mug. The idea is to keep the drink and improve how you feel. I get why that would catch your attention when your current routine isn’t doing much for you.

So, what’s actually in the pink pouch?

Coffee, meet mushrooms

Rainbow Dust combines lion’s mane, cordyceps and chaga mushrooms with ashwagandha, maca, vitamin B5 and caffeine. The Coffee version includes instant coffee. There’s also Chocolate, Vanilla Cinnamon and other flavours if you fancy a different sort of drink.

Spacegoods says the blend supports focus, energy and calm, without the jitters and crash it associates with ordinary coffee. That’s the pitch. Whether it does that for you needs more thought than the packaging gives it.

There’s nothing particularly complicated about making it. Scoop, water or milk, stir or froth. You can have it hot or cold, and a full pouch contains 30 servings. Spacegoods’ own preparation guide uses hot water, milk and a frother.

The mushrooms are the unusual bit. The rest can fit into the same five minutes you already spend making a drink.

Why I’d give the idea a look

For a start, it’s one thing to make. If you’re curious about several of these ingredients, having them together in a scoop is more convenient than measuring out separate powders. That doesn’t settle whether the blend works, but it does make it easier to imagine using.

The choice of flavours helps, too. You might want to stick with coffee. You might prefer the idea of a chocolate drink with milk. Either way, you need to enjoy the cup enough to make another one tomorrow. Nobody needs a £49 pouch they spend a month avoiding.

And you can start with seven sachets. That’s the part I particularly like: try the drink before deciding it deserves a subscription. A small pack gives you a chance to work out whether you like the flavour and making it fits your day.

The sample won’t settle the science. It will help settle whether you want a bigger bag in the cupboard.

Will it actually help you focus?

This is where I’d ease off the enthusiasm a little. The ingredients are interesting, but a list of mushrooms isn’t enough to promise a more productive afternoon.

A small 2023 lion’s mane trial studied 41 healthy adults over 28 days. It found improvement on one cognitive task after a single dose, with mixed results across the other measures. It tested a particular lion’s mane preparation, not Rainbow Dust. We can’t turn that into a promise about what this drink will do.

There’s also still caffeine in the cup: the Coffee flavour lists 120mg per serving. If you’re looking at Spacegoods because caffeine makes you feel rough, that number matters. The FDA lists jitters, anxiety and sleep disruption among the possible effects of too much caffeine, with sensitivity varying from person to person. Adding mushrooms doesn’t give us a reason to assume those effects disappear.

I’d be curious about Rainbow Dust as a drink I might enjoy making regularly. I’d be much more cautious about buying it with the expectation that it will sort out my concentration. That’s a lot to ask of a scoop of powder.

One ingredient to check before you order

Rainbow Dust contains ashwagandha. The US National Center for Complementary and Integrative Health advises avoiding it during pregnancy and breastfeeding, and does not recommend it for people with thyroid or autoimmune disorders or those about to have surgery. It can interact with medicines and cause side effects, including stomach upset; rare cases of liver injury have also been reported.

If you take regular medication or have a medical condition, ask a pharmacist or clinician about the full ingredient list before trying it. Choosing a different flavour doesn’t remove that question.

If you want more background on that ingredient, Andrew Huberman discusses ashwagandha in his episode on stress and anxiety. The useful detail: he says he doesn’t take it year-round. Jump to the ashwagandha discussion at 1:23:30.

Choose the caffeine level as well as the flavour

“Mushroom coffee” doesn’t tell you how much caffeine is in the mug. Even within Rainbow Dust, the labels differ.

The Coffee, Chocolate, Vanilla Cinnamon and Decaf Coffee labels are worth a look before choosing, especially if you avoid particular ingredients.

Chocolate has a third less caffeine than Coffee by these figures, but it still contains caffeine. That matters if you’re looking for an evening hot chocolate. And if you dislike stevia, the distinction between Coffee and Chocolate is useful before you commit to a whole bag.

For someone trying to cut caffeine, the comparison below is more useful than the word “mushroom” on the front: Rheal and DIRTEA each list 50mg per serving, while vybey’s Cacao lists 40mg. Those figures compare the brands’ own serving sizes.

For the coffee side of this, Huberman’s caffeine episode is a useful watch. A good place to start is how caffeine reduces sleepiness at 38:01, or you can skip to afternoon caffeine and sleep at 1:27:41. Those are the questions worth asking before adding another caffeinated drink to your day.

How I’d try it without committing to a full bag

The seven-sachet Chocolate pack makes sense. At £14, it costs £2 per serving before delivery, more per cup than the large pouch, but £35 less to find out whether you want more. Coffee samples are also available if that’s the flavour you intend to buy.

The sample is there to settle the everyday questions: do you like it in your usual milk or water, does it fit your morning, and would you look forward to another cup? Seven sachets can help with those decisions. They can’t establish a health benefit.

The £29 price comes with a recurring order

On 28 September 2026, Spacegoods’ Coffee Plus pouch was £49 as a one-off purchase. The monthly subscription option was £29 per delivery. Both contain 30 servings.

Prices exclude delivery and anything you mix the powder with. Spacegoods lists standard UK delivery at £3.99, with free delivery for subscriptions.

The subscription saves £20 against that one-off pouch price. It becomes a sensible option once you know you want a bag regularly. Before paying, check the selected flavour, delivery frequency and next charge; other delivery intervals can have different prices.

Spacegoods’ cancellation policy says you can cancel through your customer account or the links in your order confirmation. Do that before an unwanted renewal. Cancelling future deliveries and returning an order are separate steps.

There is a 60-day return-request window from receipt. Spacegoods needs to hear from you before anything goes back; the policy requires return approval and inspection. That is useful to know, but I’d still start small rather than buy a large order on the assumption that returning it will be effortless.

Four alternatives, depending on what matters to you

If it's greens rather than focus you're after, our greens powder guide compares the other scoop people are adding to their mornings. These prices are for the specified one-off purchases on 28 September 2026, before delivery. Cost per cup uses each brand’s stated serving size, so it compares the drinking cost rather than equal quantities of powder.

Rheal: the lowest cost per serving here

RhealRheal SuperfoodsRheal sells powdered superfood blends for everyday routines, from gut and hydration mixes to greens and a beauty-focused berry powder. The range is built around simple daily use raBuying guide · View store → Shroom Coffee is £15 for 30 servings (50p a cup), with 50mg caffeine per serving. It combines Arabica coffee, lion’s mane and maca.

It’s the first one I’d compare if you want to try mushroom coffee without spending £49 on a bag. The upfront price is close to Spacegoods’ seven-sachet sampler, but buys a month’s supply at one serving a day. The trade-off is the format: a coffee blend with a narrower ingredient list, rather than Rainbow Dust’s range of flavoured drinks.

DIRTEA: a bigger pouch with 50mg caffeine per cup

DIRTEADIRTEADIRTEA is a UK-formulated range built around functional mushroom extracts, sold as Super Blend drinks, pure powders and gummies. Most of the range is caffeine-free, so the real decBuying guide · View store → Coffee costs £38 for the 60-serving pouch, working out at about 63p a cup. Its blend contains coffee, lion’s mane, maca and B vitamins; each serving lists 50mg caffeine.

This is a useful comparison if you already know you want coffee and will get through a larger supply. Rheal costs less to try, while DIRTEA gives you twice as many stated servings in one pouch. If you’re comparing these prices, the pouch-only option is the fair one: a kit with accessories is a different purchase.

London Nootropics: sachets for work and travel

London NootropicsLondon NootropicsLondon Nootropics sells coffee blends in single-serve sachets, each combined with adaptogens such as lion's mane, cordyceps and rhodiola. The range runs from Flow, aimed at focus, Buying guide · View store → Flow comes in individual sachets. The 12-sachet box is £15, or £1.25 per drink, and combines coffee with lion’s mane and rhodiola.

The reason to choose it is portability: put a few sachets in a work bag or leave them at your desk, without carrying a pouch and measuring a scoop. At 80–110mg caffeine per sachet, it doesn’t offer the same reduction as the 50mg options above. It earns its place through convenience.

vybey: a cacao option with 40mg caffeine

vybeyvybeyvybey makes complete meal replacement shakes, nutrition bars and hydration packs for people who want a balanced meal without the cooking. Its powders combine plant or dairy proteinBuying guide · View store → Braincare Smart Focus Cacao is £39.99 for the 240g bag. At the stated 8g serving, that’s 30 drinks for about £1.33 each. It lists 40mg caffeine per serving.

This is the closest comparison here if Rainbow Dust Chocolate is the draw. Its caffeine figure is half that of Spacegoods Chocolate, which may help you choose between them. It’s still a caffeinated drink, and the upfront commitment is larger than Spacegoods’ sample pack. Cacao is the one to select: vybey also sells a Matcha version with different ingredients and caffeine.

So, is Spacegoods worth it?

Spacegoods makes sense to try if you want to rethink your daily drink and its flavours appeal to you. The sample pack gives you a manageable way to decide whether you want it as part of your routine. A full pouch makes more sense after that, and the monthly price is substantially better if you genuinely want regular deliveries.

I’d choose Rheal first for a lower daily cost, DIRTEA for a larger supply of coffee, London Nootropics for individual sachets, or vybey to compare cacao drinks with less caffeine. The question to bring back to each option is the one we started with: what do you want to change about your current routine? The right drink is the one that addresses that, whether it’s less caffeine, a format you prefer or a cost you can comfortably keep paying.

FAQs

How much caffeine is in Spacegoods Rainbow Dust?

The displayed Coffee label lists 120mg per 8g serving. Chocolate and Vanilla Cinnamon each list 80mg. The Decaf Coffee label includes decaffeinated coffee but does not give a caffeine quantity, so it should not be treated as a verified zero-caffeine option.

Can you buy Spacegoods without a subscription?

Yes. The Coffee Plus 30-serving pouch was £49 as a one-off purchase on 28 September 2026. The £29 monthly option is a recurring subscription. It's worth confirming which purchase option is selected before paying.

What is the cheapest way to try Rainbow Dust?

Of the options compared here, the seven-sachet sample pack has the lowest upfront product cost at £14, before delivery. It costs more per serving than a full pouch, but commits you to fewer drinks while you decide whether you like it.

Is mushroom coffee guaranteed to improve focus?

No. Evidence about an individual mushroom preparation does not establish that a particular blended drink will improve your concentration. I'd choose on the basis of its ingredients, caffeine, flavour and price, with any additional benefit treated as uncertain.
