Ryze mushroom coffee is a blend of instant coffee and extracts from six functional mushrooms: lion’s mane, cordyceps, reishi, turkey tail, shiitake, and king trumpet. It contains about 48 milligrams of caffeine per serving, less than half the amount in a standard cup of coffee. Whether it’s “good for you” depends on what you’re hoping to get from it. The mushrooms in the blend do have real biological activity, but the effects are more modest than the marketing suggests.
What’s Actually in the Blend
Each serving of Ryze combines a small amount of organic coffee with powdered mushroom extracts. The six mushrooms are chosen for different purposes: lion’s mane for brain function, cordyceps for energy, reishi and turkey tail for immune support, shiitake for general nutrition, and king trumpet for gut health. The product also contains MCT oil from coconuts.
The key question with any mushroom coffee is dosing. Most clinical studies on functional mushrooms use concentrated extracts at specific amounts, often several grams per day of a single mushroom. When you divide a proprietary blend across six different mushrooms in one scoop of powder, each individual mushroom may be present at levels well below what’s been studied. Ryze doesn’t disclose exactly how much of each mushroom extract is in a serving.
Brain Benefits: Real but Limited
Lion’s mane is the star ingredient for cognitive claims. It contains compounds that promote the production of nerve growth factor, a protein that helps maintain and repair brain cells. That sounds impressive, and in lab studies it is. But human trials tell a more cautious story.
In a double-blind, placebo-controlled study of healthy younger adults who took 3 grams of a concentrated lion’s mane extract (a 10:1 extract, meaning 10 grams of mushroom concentrated into 1 gram of powder), researchers found no significant overall improvement in cognitive performance or mood compared to placebo. There was one bright spot: participants performed better on a fine motor skill test 90 minutes after taking it. The study’s conclusion was that any benefits “may be task or domain specific.” And that was with a much larger dose than what you’d get in a mushroom coffee blend.
Longer-term use may tell a different story. Some older studies in people with mild cognitive decline have shown more promising results over several weeks. But if you’re a healthy adult expecting sharper focus after one cup, the evidence doesn’t strongly support that.
Energy Without the Jitters
This is where Ryze delivers its most straightforward benefit, though not necessarily because of the mushrooms. At 48 milligrams of caffeine, it gives you roughly the same kick as a cup of green tea. If your regular coffee habit leaves you anxious, jittery, or crashing by 2 p.m., switching to Ryze will reduce those side effects simply because you’re consuming less caffeine.
Cordyceps, the mushroom included for energy, does have an interesting mechanism. It contains a compound that activates a cellular pathway involved in building new mitochondria, the structures inside your cells that produce energy. Animal studies have shown increased ATP (the molecule your cells use as fuel) in the liver after cordyceps supplementation. Cordyceps also appears to improve the body’s tolerance of low-oxygen conditions.
In a 12-week randomized trial of amateur marathon runners, cordyceps supplementation led to significant improvements in 5K race times. However, the runners showed no measurable change in VO2 max or other cardiopulmonary markers. So the performance benefit was real but didn’t show up through the expected physiological channels. It’s possible the effect is more about perceived effort or recovery than raw oxygen capacity.
Immune and Stress Support
Reishi and turkey tail mushrooms both contain beta-glucans, a type of complex carbohydrate that interacts with the immune system. According to the National Cancer Institute, beta-glucans in turkey tail are thought to strengthen the immune system’s ability to fight abnormal cells, and polysaccharides in reishi may help keep cancer-fighting immune cells called lymphocytes active. This research is primarily from lab, animal, and early-phase human studies, so the practical benefit for a healthy person drinking mushroom coffee daily isn’t well quantified.
Several of the mushrooms in Ryze are also classified as adaptogens, substances believed to help the body manage stress. The proposed mechanism involves the HPA axis, the system that governs your stress hormone response. Adaptogens may help keep this system in better balance, potentially smoothing out the cortisol spikes that come with chronic stress. The concept is supported by some research, but the word “adaptogen” covers a wide range of compounds with varying levels of evidence behind them.
Gut Health Benefits
King trumpet mushroom, also known as king oyster, is less commonly discussed than the others but has some notable research behind it. In an animal study, dietary intake of whole king trumpet mushroom improved gut microbiome balance, increasing populations of beneficial bacteria like Akkermansia, Lactobacillus, and Bifidobacterium while reducing harmful strains. These are the same bacterial families found in many probiotic supplements. The mushroom also helped correct gut imbalances caused by a high-fat diet. Whether the small amount of king trumpet extract in Ryze replicates this effect in humans is unknown, but the prebiotic potential of mushroom fiber and polysaccharides is well-established.
Side Effects Worth Knowing About
For most people, a daily cup of mushroom coffee is unlikely to cause problems. But “unlikely” isn’t “impossible,” and the blend’s variety of mushroom extracts means there are several potential interactions to be aware of.
Digestive discomfort is the most common complaint. Bloating, nausea, or diarrhea can occur, particularly if you have a sensitive stomach or irritable bowel syndrome. Starting with half a serving can help you gauge your tolerance.
The medication interactions are more serious. Reishi mushrooms can influence blood clotting, raising the risk of bleeding if you take blood thinners. Cordyceps may lower blood sugar, which could interfere with diabetes medications. Both reishi and other functional mushrooms can interact with immunosuppressants and chemotherapy drugs. If you take any of these medications, this isn’t a product to start casually.
A few less common concerns are also worth noting. Chaga mushrooms (not in Ryze, but in some competing brands) are very high in oxalates and can contribute to kidney stones. Excessive reishi consumption has been linked in rare case reports to liver strain. And cordyceps, combined with caffeine, can occasionally cause a racing heartbeat or dizziness, especially on an empty stomach. People with mushroom or mold allergies should approach any mushroom coffee with caution, as allergic reactions ranging from skin rashes to, rarely, breathing difficulties have been reported.
Is It Worth the Price?
Ryze typically costs around $1.50 to $2 per serving, roughly three to four times the cost of brewing a cup of regular coffee at home. The question is whether the mushroom extracts justify that premium.
The honest answer is that you’re getting real bioactive compounds, but likely in amounts below what clinical studies have used. The most tangible benefit for most people will be the caffeine reduction itself, which costs nothing to achieve by simply drinking less coffee or switching to half-caf. The mushroom extracts may provide a mild boost to immune function, gut health, and stress resilience over time, but you’d probably get more potent effects from standalone mushroom supplements where the dose of each extract is transparent and clinically relevant.
If you enjoy the taste and the ritual, and the lower caffeine makes you feel better day to day, that’s a perfectly reasonable reason to drink it. Just calibrate your expectations to match the evidence: modest, not transformative.
