A quick note on terms: some of these are true mushroom coffees that contain real coffee (DIRTEA, London Nootropics), while others are coffee alternatives with little or no coffee (NO CRASH, MUD\WTR). We have included both, since most people searching for mushroom coffee really want the same thing: focus and energy without the jitters. For the wider picture, see our guide to mushroom coffee vs coffee.
1. NO CRASH: best for steady energy without the crash
NO CRASH is a functional mushroom chocolate drink rather than a coffee, designed specifically to avoid the spike-and-slump of caffeine. It is the most complete blend in this list, with 1000mg each of lion's mane, cordyceps, reishi and chaga, plus 300mg of KSM-66 ashwagandha, rhodiola and maca, all at research-supported doses. It comes in two versions: Steady Energy with 50mg of caffeine and Pure Calm with none, so you can match it to the time of day.
Pros: the broadest fully dosed stack here, a true caffeine-free option, sugar free and sweetened with stevia, and a chocolate taste with no earthy mushroom flavour. Third-party tested, with a 30-day money-back guarantee.
Cons: it is a chocolate drink, so it will not satisfy anyone who specifically wants the taste of coffee. Priced at the premium end at £39, though the subscription brings it down.
Fully dosed lion's mane, cordyceps, reishi and chaga plus KSM-66. Steady Energy (50mg) or Pure Calm (caffeine free).
2. Space Goods Rainbow Dust: best for flavour and hype
Rainbow Dust is the blend you have probably seen all over social media, and Good Housekeeping named it their best mushroom coffee. It blends lion's mane, cordyceps and chaga with adaptogens like ashwagandha and maca, in a sweeter, flavour-forward powder you mix with milk or water.
Pros: popular, palatable and a good adaptogen line-up.
Cons: at around 85mg of caffeine per serving it is the strongest here, close to a full coffee, so it is less suited to anyone trying to cut caffeine or avoid an afternoon crash.
3. DIRTEA Coffee: best for a real coffee taste
If you want something that genuinely tastes and brews like coffee, DIRTEA is the strongest pick. Its Super Blend pairs 100% Arabica coffee with 1000mg of lion's mane and B vitamins, with up to 80% less caffeine than a normal cup.
Pros: authentic coffee flavour, a high lion's mane dose, and a well-known UK brand.
Cons: it is built around a single functional mushroom (lion's mane), so it is less of an all-round adaptogen stack than NO CRASH or Rainbow Dust.
4. London Nootropics: best for convenience
London Nootropics makes adaptogenic coffee in single-serve sachets, which Good Housekeeping rated best for convenience. Blends like Flow and Mojo combine real coffee with mushrooms and adaptogens such as cordyceps, lion's mane and ashwagandha.
Pros: genuinely portable, good for travel and the office, real coffee base, and a low entry price of around £15 for 12 sachets.
Cons: sachets work out pricier per serving over time, and as a coffee it still carries a normal-ish caffeine load.
5. MUD\WTR: best caffeine-light and coffee-free
MUD\WTR is a coffee-free alternative built on a masala chai and cacao base with a full mushroom blend of chaga, reishi, lion's mane and cordyceps, and just 35mg of caffeine from the cacao and tea.
Pros: very low caffeine, a complete four-mushroom blend, and a distinctive spiced flavour.
Cons: the earthy, spiced taste divides opinion, and as a US brand the UK price lands at the higher end at around £40.
How to choose the right one for you
- Want to cut caffeine or stop the afternoon crash? Go for the lowest-caffeine options: NO CRASH Pure Calm (0mg) or MUD\WTR (35mg).
- Want it to taste like coffee? DIRTEA or London Nootropics, which use real coffee.
- Want the broadest mushroom and adaptogen stack? NO CRASH, with four mushrooms plus KSM-66 ashwagandha at full doses.
- Want maximum convenience? London Nootropics sachets.
Whichever you choose, the benefits of functional mushrooms build with daily use, so consistency matters more than the brand. For the science on each ingredient, see our complete guide to functional mushrooms.
Frequently asked questions
What is the best mushroom coffee in the UK?
It depends on your goal. For steady energy without a caffeine crash, NO CRASH is our pick thanks to its caffeine-free option and full mushroom and adaptogen stack. For flavour, Space Goods Rainbow Dust; for a real coffee taste, DIRTEA; for convenience, London Nootropics; for a caffeine-light coffee-free option, MUD\WTR.
Which mushroom coffee has the least caffeine?
NO CRASH Pure Calm is completely caffeine-free. Among the rest, MUD\WTR is lowest at 35mg, while Space Goods Rainbow Dust is highest at around 85mg, close to a normal coffee.
Is mushroom coffee actually worth it?
If you want lower caffeine, fewer jitters and the potential focus benefits of lion's mane and cordyceps, it can be a worthwhile swap. The mushroom benefits are gentle and build over weeks of daily use, so it works best as a consistent habit rather than a one-off.
Does mushroom coffee help you avoid an energy crash?
Lower-caffeine blends tend to cause less of a crash than strong coffee, and adaptogens like ashwagandha and reishi may help smooth the cortisol swing behind it. For why the crash happens, see our article on why you crash after coffee.
What is the difference between mushroom coffee and a coffee alternative?
Mushroom coffee contains real coffee blended with mushroom extracts (like DIRTEA and London Nootropics). A coffee alternative contains little or no coffee and uses other bases such as cacao or chai (like NO CRASH and MUD\WTR). Both aim to deliver focus with less caffeine.
