Mushroom Coffee vs. Regular Coffee: What You Need to Know
Mushroom coffee is everywhere right now — wellness influencers swear by it, specialty brands are popping up constantly, and you've probably seen claims about improved focus, better immunity, and less jitteriness than regular coffee. But what does the science actually show?
Mushroom coffee is everywhere right now — wellness influencers swear by it, specialty brands are popping up constantly, and you've probably seen claims about improved focus, better immunity, and less jitteriness than regular coffee. But what does the science actually show?
Here's our honest take as coffee roasters: mushroom coffee isn't magic, but it isn't nonsense either. The research is more nuanced than the marketing suggests. Let's look at what we actually know — and what's still just hype.

What Is Mushroom Coffee?
Mushroom coffee is regular coffee blended with extracts from medicinal or "functional" mushrooms. These aren't culinary mushrooms like shiitake or portobello — they're fungi traditionally used in Asian medicine.
The most common mushrooms used:
- Lion's Mane (Hericium erinaceus) — marketed for cognitive function and nerve health
- Chaga (Inonotus obliquus) — marketed for immune support and antioxidants
- Reishi (Ganoderma lucidum) — marketed for stress reduction and sleep
- Cordyceps (Cordyceps militaris) — marketed for energy and athletic performance
The mushrooms are typically dried, extracted, and processed into powder that's blended with ground coffee beans. Most products contain roughly 50% coffee, 50% mushroom extract — which means about half the caffeine of regular coffee.
What the Research Actually Shows
Let's go mushroom by mushroom, because the evidence varies significantly.
Lion's Mane: The Most Promising for Cognition
Lion's mane has the strongest human research behind its cognitive claims — but with important caveats.
What studies show:
A Japanese clinical trial in 50-80 year-old adults with mild cognitive impairment found significant improvements in cognitive performance after 16 weeks of supplementation. However, benefits declined after discontinuation.
A 2023 trial at Northumbria University (41 healthy adults, 1.8g/day for 28 days) found participants performed faster on certain cognitive tasks 60 minutes after a single dose, but showed no significant global cognitive improvements after chronic supplementation.
A 2024-2025 systematic review of 5 randomized controlled trials found modest improvements in cognitive scores.
The takeaway: Moderate evidence for older adults with cognitive decline; weak evidence for healthy young adults. If you're 25 and sharp, lion's mane probably won't supercharge your brain.
Chaga: Limited Human Evidence
Chaga is marketed heavily for immune support, but the research is almost entirely preclinical.
According to Memorial Sloan Kettering Cancer Center, "the safety and efficacy of chaga have yet to be evaluated in clinical studies." The immune-modulating effects documented in laboratory research haven't been confirmed in human trials.
Important safety note: Multiple documented cases of kidney damage (oxalate nephropathy) have occurred in people consuming chaga powder at 4-15g daily. One case resulted in permanent kidney damage requiring hemodialysis.
Reishi: Modest Immune Support
Reishi has some human research, primarily in cancer patients as an adjunct therapy.
A Cochrane systematic review analyzed 5 randomized controlled trials (373 participants) on reishi for cancer treatment. Patients receiving reishi with chemotherapy/radiotherapy showed modest improvements in immune markers, though the review concluded it "could be administered as an alternative adjunct to conventional treatment" — not as a replacement.
For general stress and sleep claims, the evidence is limited.
Cordyceps: Exercise Performance Potential
Cordyceps has the most interesting research for physical performance.
A 2017 study (28 participants, 4g/day for 3 weeks) found significant improvements in VO2max (+4.8 ml/kg/min vs +0.9 for placebo) and time to exhaustion (+69.8 seconds). No effects were seen after just 1 week.
Another trial in amateur marathoners (2g/day for 12 weeks) showed improved aerobic performance and lowered heart rate at submaximal intensity. The takeaway: Moderate evidence for exercise performance, but only with consistent supplementation over 3+ weeks at 2-4g/day.

Mushroom Coffee vs. Regular Coffee: Nutritional Comparison
Regular coffee contains 95-200mg of caffeine per 8oz cup with high antioxidants from chlorogenic acid and about 2 calories when black, while mushroom coffee has 50-100mg of caffeine per 8oz with high antioxidants from both coffee and mushrooms, includes beta-glucans (absent in regular coffee), and has similar calorie content.
The lower caffeine is the most practical difference for most people. If you want to reduce caffeine intake while keeping the coffee ritual, mushroom coffee offers a middle ground.
One note from Harvard Health: You would likely get more nutritional benefit from eating actual mushrooms alongside regular coffee, as whole mushrooms provide fiber and other nutrients lost in extraction.
What's Actually Supported vs. Marketing Claims
Let's be direct about this:
Supported by Evidence (With Caveats)
Claims supported by evidence include lion's mane supporting cognitive function in older adults (though effects require sustained use and diminish when stopped), cordyceps improving exercise tolerance (but only with 3+ weeks of 2-4g daily), containing 50% less caffeine than regular coffee, and being gentler for caffeine-sensitive people due to the lower caffeine content.
Not Supported or Overstated
Common marketing claims that are not supported or overstated include "boosts focus and clarity" in healthy young adults (studies show minimal to no cognitive benefit), "immune-boosting" from chaga and reishi (human clinical trials are lacking), "reduces stress and anxiety" (only trend-level effects that aren't statistically significant), being "better than regular coffee" for health (whole mushrooms plus coffee would provide more benefits), and being "scientifically proven" (most evidence comes from isolated supplements, not actual mushroom coffee products).
Quality and Safety Concerns
This is worth knowing before you buy.
The FDA doesn't require pre-market approval for dietary supplements, placing responsibility on manufacturers. Quality control is a significant issue in this market.
Concerning finding: In one study of 19 reishi supplements tested, only 5 could be validated as genuine products. The mushroom supplement industry has documented quality control problems. Potential interactions:
- Blood thinners: Reishi and chaga may increase bleeding risk
- Blood pressure medications: Additive effects possible
- Immunosuppressants: Cordyceps may interfere
- Surgery: Discontinue 2 weeks before due to bleeding risk
If you're on medications, talk to your doctor before adding mushroom coffee to your routine.
Our Honest Assessment
Here's our take as coffee people:
Mushroom coffee makes sense if you:
- Want to reduce caffeine while keeping coffee flavor
- Are specifically interested in trying lion's mane or cordyceps for their documented (if modest) benefits
- Enjoy the taste and ritual of mushroom coffee
Mushroom coffee probably isn't worth it if you:
- Expect dramatic cognitive or immune benefits
- Are paying a large premium expecting health transformation
- Could just eat actual mushrooms and drink regular quality coffee
The Harvard Health summary puts it well: mushroom coffee "probably won't do any harm" but don't expect miracles.
What About Just Drinking Good Coffee?
Regular coffee has extensively documented health benefits — decades of research linking moderate consumption to reduced risk of cardiovascular disease, type 2 diabetes, liver disease, and neurological conditions.
The compounds in quality coffee — chlorogenic acids, melanoidins, and yes, caffeine — have substantial evidence behind them. If you're drinking well-sourced, properly roasted coffee, you're already getting significant health benefits.
Adding mushroom extracts might provide incremental benefits for specific purposes. But the foundation of a healthy coffee habit is the coffee itself — its quality, freshness, and how it's produced.
Frequently Asked Questions
Is mushroom coffee actually good for you?
It's not harmful, and some mushrooms (lion's mane, cordyceps) have modest evidence for specific benefits. But the health claims are often overstated. Regular quality coffee has more robust research supporting its health benefits.
Does mushroom coffee taste like mushrooms?
Most brands taste predominantly like coffee with earthy undertones. The mushroom flavor is usually subtle. If you're sensitive to mushroom taste, try products with lower mushroom ratios.
How much caffeine is in mushroom coffee?
Typically 50-100mg per 8oz cup — about half of regular coffee. This is because mushroom powder replaces roughly half the coffee in most blends.
Can I make mushroom coffee at home?
Yes — you can buy mushroom extract powder and add it to your regular coffee. This lets you control the ratio and use your preferred coffee. Harvard Health suggests this may be more cost-effective than pre-blended products.
Is mushroom coffee safe?
For most people, yes. But chaga has documented kidney concerns at high doses, and several mushrooms can interact with medications. If you're on blood thinners, immunosuppressants, or have upcoming surgery, consult your doctor first.

The Bottom Line
Mushroom coffee occupies an interesting middle ground — it's not the miracle wellness brands claim, but it's not snake oil either. Some of the mushrooms have real, if modest, evidence behind specific benefits. The lower caffeine content is a legitimate advantage for sensitive individuals.
But if you're looking for the health benefits of coffee, the simplest answer is: drink good coffee. Quality sourcing, proper roasting, and freshness matter more than adding trendy ingredients. The research behind regular coffee consumption is robust and extensive.
