Wellness trends come and go like waves, but some of them crash into your morning routine and refuse to leave. Mushroom coffee is exactly that kind of trend. It has taken over social media feeds, wellness blogs, and health food store shelves with a kind of relentless confidence that is hard to ignore. Millions of people have swapped their regular cup of joe for a blend they claim makes them sharper, calmer, and better rested.
So what really happens when you commit to it for a full 30 days? I decided to find out firsthand, and the results were equal parts surprising and sobering. Let’s dive in.
What Exactly Are You Drinking?
Let’s start with the basics, because “mushroom coffee” sounds a lot weirder than it actually is. While mushroom coffee does, in fact, contain mushrooms, it is still actually coffee. Typical blends include an equal mix of ground mushrooms and ground coffee beans. You are not gulping down chunks of fungus. It is a powder blend, and it brews just like regular coffee.
Mushroom coffee is typically made from medicinal mushrooms rather than the culinary mushrooms you buy at the grocery store. Common varieties used include chaga, lion’s mane, reishi, cordyceps, king trumpet, and turkey tail, all chosen for their real or perceived health benefits.
It tastes similar to normal coffee, but maybe a little more nutty or earthy. People create this drink by drying mushrooms, extracting their beneficial ingredients, and adding those to regular coffee. Honestly, after a few days, I barely noticed the difference.
The Caffeine Advantage Is Real
Here is something that genuinely surprised me during my 30 days. I stopped getting that mid-morning caffeine crash. Turns out, that is not magic. It is math. By drinking a cup that is only about half coffee, you are getting only half the caffeine. Reduced caffeine intake can leave you less jittery during the day and can also improve your ability to get quality sleep at night.
According to the FDA, a standard cup of regular coffee typically contains around 95 mg of caffeine. Popular mushroom coffee blends, like Ryze, combine six functional mushrooms with a moderate caffeine dose of around 48 mg, offering sustained energy without the typical crash or jitters.
Mushroom coffee itself cannot help you get better sleep, as some suggest. However, taking in less caffeine does help some people get a better night’s rest. If you tend to be sensitive to caffeine, mushroom coffee might be a good choice for you.
Lion’s Mane and the Brain Focus Question
The claim that gets the most attention is brain performance, and lion’s mane is the mushroom everybody points to. Mechanistic studies show that lion’s mane’s bioactive compounds, hericenones and erinacines, promote the synthesis and secretion of nerve growth factor, as well as neuroprotective and cognition-improving effects. That sounds impressive, and it is, but the picture gets more nuanced when you look at actual human trials.
A randomized, double-blind, placebo-controlled study investigated the acute and chronic effects of 1.8 g of Hericium erinaceus in 41 healthy adults aged 18 to 45 years. Analysis revealed that following a single dose, participants performed quicker on the Stroop task at 60 minutes post dose. A trend toward reduced subjective stress was also observed following 28 days of supplementation.
Cognitive effects with lion’s mane have been mixed based on small and short-duration clinical trials. I think that is the honest summary. There is real signal here, but the research is young, inconsistent, and not yet definitive for healthy adults. Worth noting.
Reishi and Sleep: A Cautiously Optimistic Story
After about two weeks, I started sleeping a bit more soundly. Could it be the reduced caffeine? The reishi in my blend? Both? Reishi, known scientifically as Ganoderma lucidum, has a long medicinal history in East Asian traditions. Over 400 bioactive compounds, including triterpenoids, polysaccharides, steroids, fatty acids, and nucleotides, have been identified from Ganoderma lucidum, contributing to its sleep-promoting, antioxidant, and immunomodulatory properties.
Animal studies showed that administration of Ganoderma lucidum extract for 28 days promoted sleep by shortening sleep latency and prolonging sleeping time. The extract increased levels of the sleep-promoting neurotransmitter serotonin in the hypothalamus during this process. The key caveat, though: these are animal studies.
A 2024 review noted reductions in fatigue and anxiety among people with cancer using reishi mushroom products. However, the authors caution that more data is needed, especially in people without serious health conditions. More sleep quality research in healthy adults is genuinely needed before big claims can be made.
Chaga: The Antioxidant Powerhouse
Chaga is the unsung hero of many mushroom coffee blends. Chaga is one of the most antioxidant-rich foods on the planet. Its high antioxidant content helps combat oxidative stress, protecting cells from damage and slowing the aging process.
According to ORAC (Oxygen Radical Absorbance Capacity), an NIH-developed methodology that measures the antioxidant levels of different foods, chaga has a value of 1,104 ORAC units per gram, which is 6.5 times more than acai berry and one of the highest ORAC scores of any natural food.
Chaga is known for its antioxidant properties and immune-supporting effects. It stimulates white blood cells by supporting the production of beneficial cytokines, helping to support immunity and reduce inflammation. Still, it is worth remembering that antioxidant scores measured in labs do not always translate directly to the same effect in the human body.
The Adaptogens: Stress Claims Need Context
The purportedly healthful ingredients extracted from the mushrooms are plant-based compounds called adaptogens. The name comes from their ability to help the body adapt and respond better to stressful situations. Adaptogens have been used for centuries as part of Chinese medicine treatments.
Here is the thing, though. The National Institutes of Health notes that evidence for adaptogens still remains limited. While adaptogens in medicinal mushrooms are linked to health claims like better immunity and stress response, most evidence is from lab or animal studies. Human research on mushroom coffee is limited.
Other possible but largely unproven benefits of drinking mushroom coffee include less stress, as adaptogens can affect how much cortisol your body releases. If the adaptogens in mushroom coffee reduce the amount of cortisol in your system, that may help reduce the effect that stress can have on your body. A hopeful hypothesis. Not yet a confirmed fact.
A Booming Market Does Not Equal Proven Science
Let’s be real about what is driving this trend. It is not just lab results. It is serious money. The global functional mushroom market size was valued at USD 31.71 billion in 2023 and is projected to reach USD 65.83 billion by 2030, growing at a compound annual growth rate of 11.2% from 2024 to 2030.
According to a report by The Business Research Company, the mushroom coffee market is projected to grow from USD 2.72 billion in 2024 to USD 2.91 billion in 2025. Yelp also reported an 87% increase in searches for mushroom coffee in 2024 compared to the previous year.
That kind of explosive growth is exciting for the industry, but it also invites aggressive marketing. The hype around mushroom coffee is built on an untested assumption: that all the benefits of mushrooms continue to exist when they are processed and brewed alongside your morning coffee. We simply do not know that to be the case. Consumer enthusiasm and scientific evidence are not always the same thing.
The Problem with Label Claims
One thing I learned fast during my 30 days is that not all mushroom coffee products are created equal. The quality of what you are buying matters enormously. The quality of mushroom coffee products varies significantly based on extraction methods, the type of mushroom used, and mushroom sourcing. Moreover, water extraction and dual extraction methods yield different concentrations of bioactive compounds. Dual extraction involves both water and alcohol extraction to obtain a broader spectrum of bioactives, including polysaccharides and triterpenoids.
The European Food Safety Authority has stated that health claims about functional foods must be backed by strong scientific evidence, highlighting a significant gap between marketing and proven benefits. In February 2025, the European Food Safety Authority issued updated guidance on the evaluation of novel foods, establishing clearer but more stringent data requirements for marketing mushroom-based products in the region.
Some products may also contain added sugars or artificial flavorings, which, according to Consumer Reports (2024), can erode the potential health benefits if consumed frequently. Supplement quality and concentrations can vary. It is vital to choose high-quality products from reputable brands. Overall, products from reputable brands that follow good manufacturing practices will likely be safer.
Potential Side Effects You Should Know About
I had no major side effects during my 30 days, but that does not mean everyone will sail through the experience. There is some evidence the extracts used in mushroom coffee can be hard on digestion. People who have kidney issues or digestive troubles might be more vulnerable to these effects. In addition, certain types of mushrooms often used in mushroom coffee, notably the chaga variety, contain high levels of compounds called oxalates. A diet that contains too many oxalates puts you at risk for developing kidney stones.
Although dietary use of lion’s mane is generally considered safe, a clinical study reported patients experiencing abdominal discomfort, nausea, and skin rash in some cases.
Claims that mushroom coffee can treat or replace medications for anxiety, depression, or chronic illnesses are unsupported by clinical evidence. While research does indicate that certain mushrooms exhibit bioactive properties, they should be viewed as complementary rather than primary treatments. Medicinal mushrooms may support overall health, but they are not substitutes for pharmaceutical interventions. Healthcare professionals should be consulted before using mushroom coffee as a therapeutic alternative.
The Honest Verdict After 30 Days
After a full month, here is where I landed. The lower caffeine is genuinely useful. My sleep improved, though I cannot fully isolate mushrooms as the cause. I felt calmer in the afternoons. Whether that was psychological, the lower caffeine load, the adaptogens, or all three combined? It is hard to say for sure.
Although there are several health claims regarding the use of mushrooms and mushroom coffee for various health conditions, most of them are unverified at this moment, and more human research is needed. Although it may be safe to try for most people, you should always discuss it with your healthcare provider if you are taking medication or have a preexisting health condition.
You will experience the same benefits, and more, including the fiber, if you just eat mushrooms normally in your diet. If your goal is improving your health, your best bet is eating whole mushrooms, not drinking processed ones in your extra-expensive coffee. That is honestly the most grounded advice out there. Mushroom coffee is not a miracle drink. It is an interesting, probably harmless, potentially mildly beneficial ritual. Nothing more, nothing less.
