Cleared my brain fog
“It’s great. Delicious. Helped with energy levels. Cleared my brain fog I was stuck with after catching covid a few years ago.”
OYL is speciality coffee blended with Lion’s Mane, Cordyceps and Reishi. Same cup, same time of day — just designed for a smoother, more gradual lift instead of the spike and crash.

Which one sounds like you?
Functional mushrooms bring soluble fibres and beta-glucans that slow digestion — so the same caffeine reaches you as a gradual release, not one fast hit.
OYL isn’t a caffeine detox — it’s the same caffeine you already drink, blended with three organic, dual-extracted functional mushrooms (14:1) whose soluble fibres and polysaccharides slow how quickly it’s absorbed.
Contains cordycepin and adenosine, compounds linked to cellular energy production (ATP) — working alongside a smoother caffeine curve instead of one hard hit followed by a crash.
Contains hericenones and erinacines, compounds studied for supporting nerve growth factor — the mushroom most associated with focus and mental clarity, so the alertness from your coffee feels sharp, not scattered.
Rich in triterpenes and beta-glucans, and known as “the calming mushroom” — it supports the body’s stress response, which is exactly what an already-wired nervous system needs from its next cup. Reishi-forward in every OYL Decaf bag.
Fast spike, sharp afternoon crash.
Fibre slows absorption into a longer, steadier curve.
That’s the formula’s design intent and what customers consistently describe. It’s not yet a claim we can point to published clinical data for, so we won’t tell you it’s proven — we’d rather be upfront and let you try it for yourself.
The compounds build gradually. Here’s what to expect.
Your body adjusts. Caffeine spikes start to break. Mushroom compounds enter your system.
Compounds reach meaningful levels. Lion’s Mane kicks in. Brain fog starts lifting.
This is where it clicks. Clearer focus, calmer mind, steady energy all day.
Loading complete. Your body has what it needs. Daily coffee keeps you there.
No paid actors, no invented quotes. Just what’s actually behind OYL — and what we won’t overstate.
I’ve been drinking this exact mushroom stack — Lion’s Mane, Cordyceps, Reishi — every morning for seven years, long before OYL was a company. Coffee-sensitive customers keep telling us the same thing: they don’t want to give coffee up, they just want it to feel different. If you ever have a question about your order, you’re talking to us directly — not a call centre.
Verified 5-star reviews from real OYL customers.
“I love the deep, rich roast flavour of the Decaf — a delightful way to enjoy coffee without the jitters, and I’m seeing real improvement in my focus.”
“This is my daily morning routine now. I feel more focused and have less anxiety.”
“Really feel energised after just 21 days. More relaxed, and I don’t need multiple cups anymore — that’s huge for me.”
“No jittery after-effects of caffeine and more mental clarity. I’m on month two now and can’t see myself going back to regular coffee. Highly recommend!”
“Used it for 30 days without fail and felt a real increase in mental focus, plus a calming effect on my whole being.”
“Definitely sleeping better and have more energy. Already re-ordered through subscription — I’d absolutely recommend it.”
“Amazing product and customer service to match. Less brain fog, more productive overall. Onto month 3 and not going back.”
“It makes me feel clear-headed and awake, but not wired awake. I love it.”
One subscription replaces the coffee you’re already buying and any separate mushroom or fibre supplements you’d otherwise be juggling.
Message us. OYL’s guarantee and easy-cancel policy mean the risk sits with us, not you — we’d rather make it right than have you keep a subscription that isn’t working.

Instant and Ground still contain real coffee, so if you're highly sensitive you may want to start with Decaf or the caffeine-free Mushroom Only extract. The blend is designed to support a smoother caffeine curve — it isn't a guarantee of zero stimulation, so start with whichever format matches your own tolerance.
It's the thinking behind how we built the blend, and it's consistently what our customers report — but we won't tell you it's clinically proven, because it isn't yet backed by published data. We'd rather be straight with you about that and let you try it for yourself.
No — taste is the single most-mentioned thing in OYL’s reviews. Customers consistently say it’s surprised them by just tasting like good speciality coffee.
Instant and Ground carry normal speciality-coffee caffeine. Decaf is mountain-water-process decaffeinated. Mushroom Only has no coffee and no caffeine at all — it’s a pure extract you add to anything.
Everyone’s caffeine sensitivity is different, but most customers describe the first real shift landing in weeks two and three, as Lion’s Mane and Reishi build up with daily use — see the four-week roadmap above.
Message us. We’d rather sort it out or refund you than have you sit on a subscription that isn’t earning its place in your morning.
Yes — pause, skip, swap formats or cancel from your own account portal whenever you like. No phone calls, no hoops.
No. Every format is available as a one-time purchase too — subscribing simply locks in the better price and keeps it arriving automatically.
