A functional mushroom drink is a hot (or cold) beverage made with extracts from culinary and medicinal mushrooms — like Lion's Mane, Cordyceps, Chaga and Reishi — combined with other adaptogens and nutrients. Unlike regular supplements, they're designed to be a daily ritual that's actually enjoyable to drink.

NO CRASH is a functional mushroom hot chocolate. One 8g scoop gives you Lion's Mane, Cordyceps, Chaga, Reishi, KSM-66® Ashwagandha, Rhodiola and Maca — plus a complete vitamin foundation of B12, B6, D3 and K2. Rich, smooth chocolate flavour. No earthy mushroom taste.

The evidence is promising and growing. Several studies show Lion's Mane can support cognitive function and focus. Cordyceps is associated with energy metabolism and endurance. KSM-66® Ashwagandha has a strong body of research linking it to cortisol regulation and stress response. Rhodiola has been studied for mental fatigue.

Effects aren't instant — most people notice something in the first week or two, with the fuller picture emerging after a month of consistent use. That's why we offer a 30-day money-back guarantee: if you don't notice a difference, we'll refund you in full.

Completely different species, and completely legal. Lion's Mane, Cordyceps, Chaga and Reishi are culinary and medicinal mushrooms — they have no psychoactive properties and no connection to psilocybin mushrooms beyond being fungi.

NO CRASH is third-party tested for purity, heavy metals, mould and mycotoxins. All ingredients are at clinically studied doses and fully compliant with UK food supplement regulations.

Most people notice something in the first one to two weeks — typically clearer mornings, steadier energy through the afternoon, and less of that 3pm slump. The cognitive effects of Lion's Mane and Cordyceps tend to build over four to eight weeks of daily use.

If you were low in B12, B6 or D3 (common in the UK — around 1 in 5 adults are deficient in at least one), the vitamin foundation can work faster than the mushrooms. Give it a full month before drawing conclusions. Our 30-day guarantee means there's no risk in doing so.

Yes — and some of our customers do. NO CRASH is an enhancement to your existing routine, not a replacement for it. The Steady Energy version contains 50mg of natural caffeine (roughly half a cup of coffee), so it works well as a morning companion or an afternoon alternative when you want focus without a late caffeine hit.

The Pure Calm version is caffeine-free — ideal if you're sensitive to caffeine or want something you can drink any time of day.

Choose your blend — Steady Energy (50mg caffeine) or Pure Calm (caffeine-free) — then select subscribe at checkout. A fresh 30-serving pouch arrives every month, automatically.

You can pause, change frequency, swap blends or cancel anytime from your account. No lock-in, no awkward phone calls. The 30-day money-back guarantee applies to every order, including subscription orders.
