Why this coffee
Immunity BoostMedium Roast · Guatemala
Can your morning coffee actually support your immune system?
Yes — if the functional mushrooms actually survive the trip into your cup. Ours do.
✓500mg fruiting body liquid extract per 8oz cup
✓Fruiting body only — up to 15× more actives than mycelium
✓Infused into the bean, not dusted on the grounds
✓Third-party tested for potency, mold & heavy metals
✓Mushrooms grown in Colorado at MycoLove Farms
Why it works
Your immune system works hard every day. Give it backup.
Immunity Boost is a smooth, chocolatey medium roast from Guatemala's Nahualá highlands, infused with five of the most-studied immune-supporting mushrooms on earth — reishi, turkey tail, chaga, cordyceps and lion's mane. No earthy taste, no chalky powder, no compromise on the coffee.
No supplement can promise you'll never get sick. What these mushrooms can do is support your immune system's baseline so it's better equipped to do its job — and because the benefits build with daily use, coffee is the ideal delivery. You're already drinking it every morning. Just swap your beans.

Taste, health & sustainability
The three reasons it earns a place in your routine.
Taste
How does it taste?
Chocolate, caramel and grape notes in a low-acid medium roast. The mushrooms are infused into the bean — not dusted on top — so there's no earthy or medicinal aftertaste. It tastes like genuinely good coffee.
Health
What's actually in it?
Five fruiting-body mushrooms delivering 500mg of fruiting body liquid extract per cup — third-party verified to survive roasting and land in your brewed coffee, not your filter.
Sustainability
Where does it come from?
Fair Trade, USDA Organic Guatemalan beans; mushrooms grown locally at MycoLove Farms in Colorado — never imported commodity mycelium.
The Peak State Infusion Process™
Most mushroom coffees mix powder into ground coffee after roasting — where it sits on the grind and ends up trapped in your filter, so the dose on the label rarely reaches your cup. We do it backwards: the mushrooms are extracted into a concentrated tincture and botanically infused into the beans after roasting, sealing the extract inside the bean before it ever reaches your grinder.
500mg
fruiting body liquid extract per 8oz cup — every brew, every method
How Peak State stacks up
The first mushroom coffee that tastes like coffee
We made the mushroom coffee we actually wanted to drink — best-in-class taste, the first-ever whole bean, and real fruiting body liquid extract instead of cheap mycelium powder.

Questions people ask about Immunity Boost
Straight answers — the same ones we'd give you in person.
Can mushroom coffee help prevent you from getting sick?+
No supplement can guarantee it. But the five mushrooms in Immunity Boost support your immune system's baseline function, and at 500mg of third-party-verified fruiting body liquid extract per cup, daily consistency is where the benefit compounds.
What are the five mushrooms and what does each one do?+
Reishi anchors immune and stress response; turkey tail brings clinically studied PSK polysaccharides; chaga adds one of the highest antioxidant profiles of any food; cordyceps fuels cellular energy; and lion's mane keeps inflammation — a primary immune suppressor — in check.
How long does it take to notice a difference?+
Functional mushrooms work cumulatively. Most research uses daily supplementation over weeks; many customers report getting run-down less often during busy, high-stress stretches after a few weeks of consistent use.
Getting into my Peak State to start the day. I really enjoy Calm Descent. It has a great aroma delicious taste, is easy on the stomach, and doesn't give the caffeine jitters.
Excellent Brew.
Very well done ! Excellent Flavor, smooth and strong! Definitely promotes an efficient and well balanced day.
The only note I have for it is that it does make me slightly jittery for a bit however the produivity is worth it.
Looking forward to trying the beans next.!
Super happy to have found a mushroom blend that actually tastes good and does what it says it will do. Thank u
I enjoy the stress less dark roast coffee with mushrooms. The flavor is so good that it makes you feel like another cup. It is low on acid, which does not upset your stomach. In addition to it is mold free, and it is infused with mushrooms for the antioxidants that your body needs. I have been drinking it for years and enjoy every cup I drink.
We enjoy the Immunity Boost coffee with the infused mushroom blend. We had previous bought it from another supplier, that ended. Then Peak State reached out to us and told us they had it available. We immediately subscribed as customers. This is a photo of our morning set up. We use a manual grinder, because husband says, jokingly, we are contributing our daily exercise program. Great experience with product and customer service. Thanks, Peak State team.
I first tried mixing it with the stress less blend And they weren't that great together. But when I tasted it on its own, it was really good. Both of them taste really good on their own.
I love how gentle this coffee is on my stomach. I don't get the upset stomach issues that I'd usually get with regular coffee or jitters. It has an delicious, fresh taste and I look forward to drinking it daily. The added benefits of the mushrooms makes this so unique and makes a difference in my energy throughout the day and I get less brain fog. Highly would recommend to anyone!!
As always, just love this coffee! I have been mixing decaf with Stress Less and just decided to try Stress Less on its own. I am prone to getting jittery with full caffeine coffee but not with this! It is nice and strong without the jitters. Love it!
Discovered peak state through the bolder boulder's runners expo a few year's ago. Since then i always enjoy the samples and purchase a bag of brain sustain. This year i tried immunity boost and loved the taste without any sweetener. I haven't gone to any other brand since. Peak state gets it right.
One of the best coffees I’ve ever tasted. I noticed the benefits right away with energy level increasing, and I love the fact that everything‘s organic in it as the only stuff I eat. I got less brain fog, a boost of energy and all over happiness definitely will try this spread again. Thank you for giving me the opportunity.
I look forward to getting out of bed every morning to start my day by brewing Peak State Coffee. I love the delicious taste and it awakens my sluggish morning mind and makes it sharper and more focused. It gives me energy too. I also love the confidence that it's clean and responsibly sourced. I love Peak State Coffee and am happy that it starts off every day for me!!
I really liked the taste of this coffee. It tastes exactly like a standard coffee but I like the extra health benefits. No bad side effects or anything!
It's the BEST COFFEE ever! We're real coffee fans (usually drink too much in the morning) - It's the best part of starting the day. Coffee never lets me down - except it. makes me jittery when I over do. NOT PEAK COFFEE-IT'S SO SMOOTH & NEVER DO I GETJITTERY OR ACID STOMACH! IT NEVER DISAPPOINTS! We also are gluten free vegans, & especially enjoy THE BENEFITS - MUSHROOMS (which we can't taste)., nutrients which I desperately need & esp. good for the environment & workers who grow & harvest. Peak Coffee makes me feel good about my doing something positive for the world, humanity & myself! I WILL NEVER DRINK ANY OTHER COFFEE!!! WE'VE WAITED A LONG TIME FOR THIS COFFER & IT'S WORTH THE WAIT! THANK YOU FOR YOUR HARD WORK & CARING.

Excellent tasting coffee. Looking forward to ordering more in the near future. I greatly appreciate that you take the time to send a sample prior to committing to an order. Thank you so much!
Peak State Coffee has made me love coffee again. Their low-acid Stress Less fits my style so well, I never start a day without it. And their subscription service makes getting my coffee so easy… it comes the same time every month and lets me get it early or postpone it if that’s what I need. I love Peak State Coffee!!!
I enjoyed the coffee. We saw it at the farmers market type thing up in Denver. I can’t remember the exact title. The lady didn’t seem to know too much about it, but I got the stress less coffee and I’ve enjoyed it. Need to double check with the expenses before I order my next single pack.
