What Is Mushroom Coffee?

Mushroom coffee is made by blending ground coffee beans with powdered medicinal mushrooms. Medicinal mushrooms—aka functional mushrooms—are superfoods that contain nutrients, antioxidants, and adaptogens that offer several potential health benefits. Mushrooms commonly used to make mushroom coffee include:

Lion’s mane
Reishi
Shiitake
Chaga
Turkey tail
Maitake
Cordyceps

The fruiting bodies of the mushrooms are first dried and finely ground into a powder before being mixed with coffee grounds. The ratio of mushroom to coffee grounds varies by product, depending on the desired flavor profile. Mushroom coffee has a lower caffeine content than your regular cup of coffee and may be a good option for those wanting to reduce their caffeine intake without cutting it out completely.

Mushroom coffee can be purchased in several forms to suit your personal preferences.

Instant mushroom coffee: The mushroom coffee blend is brewed into a concentrated coffee extract that’s then dried into a powder. Simply mix the powder with hot or cold water for a quick and easy drink. Four Sigmatic Organic instant coffee is a great example, along with Laird Superfoods, which makes an instant latte version.
Ground mushroom coffee: The combined powdered mushrooms and coffee grounds are roasted to develop a rich, earthy flavor with creamy and nutty notes. Consumers brew it just like regular coffee using water and a coffee maker. RYZE—a brand we tackled in our in-depth RYZE Mushroom Coffee review—is an excellent option for ground coffee fans.
Mushroom coffee pods: Each pod contains a pre-measured coffee and mushroom powder blend to brew a single serving. They’re roasted to enhance flavor and can be used in a coffee maker, just like standard coffee pods.

Each option offers a different way to enjoy mushroom coffee, whether you prefer the convenience of instant coffee, the rich flavor of ground coffee, or the simplicity of coffee pods.

Benefits of Mushroom Coffee

The potential benefits of mushroom coffee for humans haven’t been well studied. While research suggests that medicinal mushrooms may offer several health benefits, there’s limited evidence to confirm these health benefits carry over when consumed as mushroom coffee rather than the whole mushroom. Based on the limited research available, here are some of the potential health benefits of mushroom coffee.

May Help Improve Immunity

Mushroom coffee is often made using mushroom extracts that may boost your immune system by enhancing your immune response and protecting those disease-fighting cells from damage caused by free radicals.

Turkey tail mushrooms contain polysaccharide K (PSK), a chemical compound that might strengthen the immune system in ways that may help combat cancer¹. Several studies show that PSK may reduce the risk of recurrent cancer and lengthen the lifespan of cancer patients who took PSK alongside chemotherapy.

Reishi mushrooms may strengthen the immune system in those with lung cancer and potentially help prevent colorectal cancer. It contains compounds that reduce inflammation and could help cancer-fighting immune cells¹, called lymphocytes, stay active.

Another common mushroom used in mushroom coffee—maitake—contains beta-glucans that can stimulate macrophages, NK cells, and T-cells. These immune cells coordinate to protect the body from a wide range of pathogens and abnormal cells, such as cancer cells. These beta-glucans may have antitumor effects on breast cancer² cells by inhibiting cell growth and preventing the spread of tumors.

May Help Reduce Inflammation

Medicinal mushrooms contain substances with antioxidant properties. Antioxidants help reduce inflammation and protect cells from oxidative stress that can lead to illness, infection, and disease.

Mushroom coffee that includes lion’s mane may offer anti-inflammatory and neuroprotective benefits. Lion’s mane mushrooms work by inhibiting specific proteins and pathways that cause inflammation. It’s particularly effective at reducing inflammation in the brain², making it potentially useful when treating neurodegenerative diseases.

Shiitake mushrooms, often used in mushroom coffee, contain polysaccharides called lentinans and other compounds that might help reduce inflammation. Studies on mice indicate that lentinans may lower the levels of inflammatory molecules and reduce the effects of endotoxins², toxic substances found in certain bacteria.

May Assist in Lowering Cholesterol

Mushroom coffee contains medicinal mushrooms that could help reduce cholesterol levels and improve heart health.

In a study done on rodents³, reishi extract reduced total cholesterol, triglycerides, and LDL cholesterol (“bad” cholesterol) while increasing HDL cholesterol (“good” cholesterol). These findings suggest that reishi mushroom extracts could help lower the risk of heart disease by improving lipid profiles.

Shiitake mushrooms are another type of medicinal mushroom with potential cholesterol-lowering properties. Shiitake mushrooms contain beta-glucans, a type of soluble fiber known to help lower cholesterol levels⁴. Beta-glucans help decrease the absorption of cholesterol and promote its excretion.

May Contribute to Lower Stress Levels

Several types of mushrooms have adaptogenic properties. Adaptogens can help reduce the effects of stress on the body and may result in less feelings of anxiety. They influence the body’s stress response system to resist physical, chemical, or mental stress⁵.

Cordyceps is an adaptogenic mushroom that influences CREB binding protein (CBP), a protein involved in regulating genes that protect against stress. By affecting CBP and other pathways, Cordyceps may help reduce the risk of depression⁶, a mood disorder associated with mental stress.

Lion’s mane is another adaptogenic mushroom commonly used in mushroom coffee. Studies conducted on rodents indicate that lion’s mane can increase levels of dopamine⁷, serotonin, and norepinephrine in stressed subjects. These “feel-good” brain chemicals play a role in regulating mood and pleasure, potentially helping to reduce stress and alleviate symptoms of depression.

Risks and Possible Downsides of Mushroom Coffee

Mushroom coffee offers many potential benefits, such as reducing inflammation and stress, but there are also some drawbacks to consider. Before trying mushroom coffee, consider factors like its cost, the limited evidence supporting its benefits, and possible side effects.

Higher Price

Mushroom coffee typically comes with a higher price tag compared to regular coffee. The cost is likely higher due to the additional ingredients (mushroom extracts), more complex production process, and perceived benefits. People who choose mushroom coffee may be willing to pay a premium for specialty products made with high-quality medicinal ingredients.

Lack of Research

As previously mentioned, we lack human studies on the effectiveness of mushroom coffee in relation to health benefits. While there’s evidence supporting the benefits of medicinal mushrooms, many of these were done on rodents or in a lab. It’s also unclear how the potential benefits of functional mushrooms translate when they’re combined with coffee. Further research is necessary to verify the health claims, safety, and effectiveness of mushroom coffee.

Potential Side Effects

Potential side effects of mushroom coffee can include gastrointestinal discomfort, allergic reactions, dry mouth, or itchiness. Mushroom coffee also contains caffeine, and while the amount is typically lower than the average cup of black coffee, it can still cause jitters, stress, or anxiety in those with caffeine sensitivity. If you’re sensitive to caffeine, you may need to limit your intake.

If you have any health conditions or are taking prescription medications, it’s important to consult your doctor or a registered dietitian nutritionist (RDN) before trying mushroom coffee.

What Is Mushroom Coffee? Final Thoughts

Mushroom coffee is created by blending coffee grounds with powdered medicinal mushrooms. It has less caffeine than regular coffee and may offer potential benefits linked to medicinal mushrooms. Limited research suggests functional mushrooms could help improve immunity, reduce stress, lower cholesterol, and decrease inflammation, but there isn’t enough research to confirm these benefits definitively. While mushroom coffee can be more expensive, it might be a worthwhile choice for those looking to enhance their health while reducing their caffeine intake.
