Ryze mushroom coffee blends six functional mushrooms with arabica coffee to deliver roughly 48 milligrams of caffeine per cup, less than half what you’d get from a standard cup of coffee. The proposed benefits range from sharper focus and better energy to improved sleep and a calmer stress response, largely driven by the mushroom blend rather than the coffee itself. Here’s what each ingredient actually does and where the evidence stands.
Focus and Mental Clarity From Lion’s Mane
Lion’s mane is the headliner for cognitive benefits. It contains compounds called hericenones and erinacines that promote the production of nerve growth factor, a protein your brain uses to maintain and regenerate neurons. In practical terms, this supports neuroplasticity, your brain’s ability to form new connections and adapt.
The clinical evidence is promising, if still limited in scale. In one trial, older adults who took lion’s mane daily for 16 weeks showed measurable cognitive improvement. Another study found benefits after 12 weeks of daily use. Perhaps most interesting for the “morning coffee” use case: a study in healthy young adults found improved performance on a cognitive test measuring response speed and focus after just a single dose, with effects appearing within 90 minutes. That timeline aligns well with drinking a cup in the morning and expecting sharper thinking by the time you sit down to work.
Energy Without the Crash
Cordyceps is the ingredient Ryze leans on for energy. The proposed mechanism is straightforward: cordycepin, an active compound in cordyceps, activates a cellular pathway that triggers the production of new mitochondria, the structures in your cells that generate energy. Animal studies have shown higher ATP (cellular fuel) concentrations in the liver after cordyceps supplementation, suggesting a genuine boost in bioenergy status.
The exercise performance claims are less clear-cut. A randomized, placebo-controlled trial in amateur marathon runners found no statistically significant improvement in VO2 max (a measure of how efficiently your body uses oxygen during exercise) after 12 weeks of supplementation. So while cordyceps may support general feelings of energy and reduce fatigue, don’t expect it to replace your training plan. The more noticeable benefit for most people is likely the combination of cordyceps with the lower caffeine content. At 48 milligrams per serving, you’re getting enough caffeine to feel alert without the jitteriness or afternoon crash that comes with a 95-to-200 milligram cup of regular coffee.
Stress Reduction and Better Sleep
Reishi mushroom has been used in Traditional Chinese Medicine for centuries to calm the mind and promote relaxation. Modern research points to triterpenes, specifically ganoderic acids, as the active compounds. These have a molecular structure similar to steroid hormones and appear to act as adaptogens, helping your body regulate its stress response rather than simply sedating you.
A randomized, double-blind, placebo-controlled trial in young adults found that participants taking a mushroom supplement had significantly reduced salivary cortisol (your primary stress hormone) by day 25 compared to placebo. The same trial measured sleep quality using a standardized index and found statistically significant improvements in overall sleep quality, including better sleep duration, efficiency, and the time it takes to fall asleep. These improvements appeared as early as day 13 and held through the final assessment at day 25. For someone replacing their afternoon or even morning coffee with a lower-caffeine mushroom blend, the combined effect of less caffeine and reishi’s calming properties could make a noticeable difference in sleep.
Immune System Support
Turkey tail and shiitake mushrooms are both rich in polysaccharides, particularly beta-glucans, which are some of the most well-studied immune-supporting compounds in the mushroom world. These polysaccharides work by modulating your immune system’s inflammatory signaling. Lab research has shown that polysaccharide-rich extracts from turkey tail reduce the expression of key inflammatory markers in activated immune cells, essentially helping to dial down excessive inflammation rather than simply boosting immune activity across the board.
This is an important distinction. “Immune support” doesn’t mean your immune system gets stronger indiscriminately. It means the mushroom compounds help your immune response stay balanced, dampening overreaction while still supporting normal function.
Gut Health From King Trumpet
King trumpet (also called king oyster) mushroom is the ingredient most relevant to digestion. Mushroom extracts like king trumpet act as prebiotics, meaning they pass through your digestive tract intact and selectively feed beneficial bacteria. Research has shown that king oyster mushroom extract stimulates the growth of probiotic bacteria, like lactobacillus strains, without promoting the growth of harmful pathogens. In studies measuring gut bacteria populations, groups receiving king oyster mushroom extract had significantly higher counts of lactic acid bacteria in the intestinal tract.
This prebiotic effect is subtle. You won’t feel it the way you feel caffeine, but over time, a healthier balance of gut bacteria supports digestion, nutrient absorption, and even immune function, since a large portion of your immune system operates in the gut.
How to Prepare It
Ryze is an instant powder, not a brew-and-filter coffee. You add one tablespoon (about six grams) to a mug, pour in eight ounces of hot water, and stir until dissolved. The base is 100% arabica coffee blended with all six mushrooms: lion’s mane, cordyceps, reishi, shiitake, turkey tail, and king trumpet. You can add milk, a sweetener, or froth it with a small whisk or electric frother for a latte-style texture. A 30-serving bag currently runs about $27 on subscription, which works out to roughly $0.90 per cup.
Potential Side Effects Worth Knowing
Mushroom coffee is generally well tolerated, but it’s not risk-free. The most common complaint is digestive upset: bloating, nausea, or diarrhea, especially in people with sensitive stomachs or conditions like IBS. Lion’s mane and reishi extracts have both been specifically linked to stomach discomfort in some users.
Reishi can influence blood clotting, which raises the risk of bleeding if you’re taking blood-thinning medications. Other potential drug interactions include diabetes medications, chemotherapy drugs, and immunosuppressants. If Ryze contained chaga (it doesn’t, but many competing brands do), the high oxalate content would be a concern for kidney stone risk.
Allergic reactions are uncommon but possible, since mushrooms are fungi and can trigger responses in sensitive individuals. Symptoms range from mild itching or rash to, very rarely, more serious breathing difficulties. People with chronic kidney or liver disease and those who are pregnant or breastfeeding should be particularly cautious with daily mushroom coffee consumption.
