The Rise of Mushroom Coffee
Mushroom coffee has become a headline trend in wellness circles, with global market estimates exceeding $3.2 billion in 2025 and projected growth through the next decade. Blending traditional coffee with powdered functional mushrooms, this beverage is promoted as a gentler caffeine experience that may support focus and well-being. But how much of that is supported by science — and how much is marketing? Let’s look at the evidence, the popular brands, and how to brew it safely.
What Exactly Is Mushroom Coffee?
Mushroom coffee typically combines roasted coffee grounds with dried, powdered extracts of mushrooms such as lion’s mane, chaga, reishi, and cordyceps. The extraction process concentrates certain compounds — including beta-glucans, polysaccharides, and triterpenoids — that are under study for potential biological activity.
Because it’s usually a half-and-half mix of coffee and mushroom powder, the caffeine content often falls between 50 and 100 mg per cup, lower than that of typical coffee (95–200 mg). These mushrooms contain adaptogenic and antioxidant compounds that may help the body maintain balance during stress — though research on human outcomes remains limited and inconclusive.
What Research Actually Shows
Cognitive Function and Focus
Lion’s mane (Hericium erinaceus) has been studied for compounds that may support nerve growth factor production. A small human trial (Japan, 2009) on older adults showed modest improvements in cognitive testing that reversed after supplementation stopped.
Evidence for “brain benefits” in healthy adults is preliminary, and the studies tested isolated mushroom extracts — not coffee formulations.
Stress and Mood
Reishi (Ganoderma lucidum) is described in early research as an adaptogen, possibly influencing cortisol and immune signaling.
A pilot study in post-menopausal women reported reduced self-rated anxiety after lion’s mane intake. However, long-term data and replication are lacking.
Immune and Antioxidant Effects
Laboratory studies show beta-glucans from chaga and reishi can stimulate certain immune cells. Yet, as Harvard Health notes, most of this evidence comes from test-tube or animal studies, not from people drinking mushroom coffee.
The extraction, heat, and processing steps in commercial coffee may alter these compounds’ activity.
Bottom line: Current research supports potential but not proven benefits. Human trials on mushroom coffee itself are minimal.
Comparing Leading Brands (as of 2025)

Observations
Both RYZE and MUD\WTR use proprietary blends without revealing individual mushroom dosages — making it difficult to compare potency.
MUD\WTR substitutes black tea for coffee and uses warming spices for flavor.
RYZE includes fats (MCT oil, coconut milk) that may affect taste and texture.
These are lifestyle beverages, not regulated supplements, and effects vary among users.
Brewing Methods: Safe & Effective Approaches
Pour-Over
Heat water to ~200 °F (93 °C).
Use a 16 : 1 water-to-coffee ratio.
Pour a small bloom, wait 30–45 seconds, then finish slowly over 2–3 minutes.
Customize with milk, oat cream, or mild sweeteners.
French Press
Pre-warm the press, discard water.
Add coarsely ground mushroom coffee.
Steep 6–10 minutes.
Press gently halfway to avoid grit.
Brewing tips:
Use filtered water.
Store grounds in airtight containers away from heat and light.
For extracts, dissolve in a splash of hot water before adding to coffee.
⚠️ Safety and Side-Effect Considerations
Who Should Avoid or Use Caution
Pregnant / breastfeeding individuals – insufficient data on safety.
People with autoimmune disorders – immune-stimulating mushrooms could aggravate symptoms.
Those on medication – especially blood thinners, diabetes drugs, or immunosuppressants.
Anyone with kidney-stone history – chaga is high in oxalates.
Possible Side Effects
Mild digestive discomfort from mushroom fiber (chitin).
Jitters or anxiety in caffeine-sensitive individuals (even at reduced levels).
Rare allergic responses, such as rash or throat irritation.
General Intake Guidance
The U.S. FDA cites 400 mg caffeine/day as a safe upper limit for most adults. One to three cups of mushroom coffee typically provide 150–300 mg total caffeine, depending on brand and portion. Human data on “optimal” mushroom dosages remain limited; manufacturers often suggest 500–1,000 mg lion’s mane equivalent daily, which appears well tolerated in short-term studies.
💬 Common Questions
Does it taste like mushrooms? Usually not — quality blends taste like smooth coffee with faint earthy notes.
Can it replace regular coffee? It can substitute for some people seeking lower caffeine, but expect a lighter body and milder kick.
When will I notice effects? Caffeine acts immediately; any adaptogenic or mood effects, if they occur, may take several weeks of consistent use.
Is it worth the price? Mushroom coffee ($1.20–$1.70 per serving) costs more than home-brewed coffee ($0.20–$0.50) because of ingredient sourcing and processing.
Can I DIY it? Yes — blend 1 tsp of verified mushroom extract powder into your brewed coffee. Choose reputable suppliers with third-party testing.
The Realistic Takeaway
Mushroom coffee can be an enjoyable way to moderate caffeine and explore functional ingredients. Scientific support is promising but preliminary — most findings relate to individual mushroom extracts rather than finished beverages.
Consider trying it if you:
Experience caffeine sensitivity
Enjoy earthy flavors and wellness trends
Prefer slower, sustained energy
Think twice if you:
Have autoimmune or chronic health issues
Take prescription medications
Expect rapid or dramatic health changes
As Harvard Health summarizes, eating mushrooms as part of a balanced diet may offer similar nutritional value at lower cost. Still, for those who enjoy the ritual, mushroom coffee is a relatively safe, low-risk experiment — when used responsibly.
