Mushroom coffee can give you energy when it contains caffeine, but the amount depends on the product and roast. The mushroom ingredients may be part of the ritual and flavor, yet human research on the finished mushroom-coffee drink is still early. Start with the label: caffeine amount, named mushroom ingredients, taste style, and cost per cup.

What actually gives mushroom coffee its energy?
For a coffee-based blend, caffeine is the clearly named stimulant on the label. RYZE says its medium-roast mushroom coffee has about 48 mg of caffeine per cup, while its dark roast has 80 to 90 mg per serving. Its product page says the medium roast contains organic instant coffee, a six-mushroom blend, and a prebiotic fiber blend.
RYZE markets cordyceps as support for natural energy production and lion’s mane as support for focus. Those are the maker’s claims. Harvard Health explains that mushroom-coffee brands often make claims about energy, focus, sleep, immunity, and metabolism, while well-designed human trials of mushroom coffee itself are lacking.

What caffeine amount and exact mushroom extract are you getting?
| Label question | What the RYZE page states | What to confirm |
|---|---|---|
| Caffeine | 48 mg per medium-roast cup; 80–90 mg per dark-roast serving | Which roast and serving you are choosing |
| Mushroom names | Cordyceps, reishi, turkey tail, king trumpet, shiitake, and lion’s mane | Amount of each mushroom |
| Extract detail | The page calls it an organic Super6 mushroom blend | Extract type and mushroom-specific amount |
| Other ingredients | Organic instant coffee plus acacia, inulin, and tapioca fiber | Whether those ingredients fit your preferences |
| Taste | RYZE describes it as smooth and creamy, with a nutty aroma and robust flavor | Whether you prefer that profile or plain coffee |
That level of detail matters. A blend name tells you which mushrooms are present, but it does not tell you the exact extract or amount for each one. If that information will decide your purchase, ask the company for the current label before ordering. Our mushroom powder guide explains the label details worth comparing.
Do human studies support mushroom coffee for energy?
Not for the finished drink. Harvard Health’s mushroom coffee review says human research on medicinal mushrooms is very limited, and that none of the research it discusses was conducted on mushroom coffee. That means an ingredient story is not the same as a human result for a particular coffee blend.
One named 2019 study, Caffeine metabolism during cultivation, examined oyster mushrooms grown with spent coffee grounds. It found caffeine and related compounds in the growing system, and estimated that roughly 250 kg of fresh oyster mushrooms would be needed to equal the caffeine in one espresso. It was a cultivation study, not a study of energy, focus, or a mushroom-coffee product in people.
What the current research can and cannot answer
| Population | Formulation | Comparator | Outcome | Duration | Harms | Uncertainty |
|---|---|---|---|---|---|---|
| Not reported in a human mushroom-coffee trial | Finished mushroom coffee | Not reported | Energy from the finished drink | Not reported | Not reported | Harvard Health says well-designed human trials on mushroom coffee are lacking. |
| Oyster mushroom cultivation system | Spent coffee grounds and oyster mushrooms | Growing conditions and substrates | Caffeine metabolism and mushroom cultivation | Growth period | Not an energy-safety study in people | It cannot tell you whether a retail mushroom coffee improves energy. |
This is the key distinction when an ad promises steady energy: coffee caffeine is measurable on a product label, while the finished blend needs its own human study to answer an energy claim. A lion’s mane or cordyceps name on a package does not fill in that missing product-specific result.
Which mushroom coffee is best for energy?
There is no single best choice from the available human evidence. Choose by the job you want the cup to do:
- Lower listed caffeine: RYZE medium roast lists 48 mg per cup.
- More coffee-like listed caffeine: RYZE dark roast lists 80 to 90 mg per serving.
- Clearer mushroom comparison: choose a label that gives the mushroom species, exact extract information, and amount of each ingredient.
- Budget comparison: divide the current package price by the stated servings. Prices and bundles change, so check the checkout for today’s figure.
For a broader label-first comparison, see what to check in mushroom coffee. RYZE is one brand to compare by its current label rather than by a broad energy promise.
What is the downside of mushroom coffee?
The practical downside is uncertainty. Mushroom coffee often costs more than plain coffee, and a mushroom blend may not state the exact extract or amount you want to compare. Taste can also differ: Harvard Health says people often describe mushroom coffee as nutty or earthy, though some notice little mushroom flavor.
Caffeine can matter for sleep. The NHS sleep guidance says coffee and other caffeinated drinks can make you feel more awake and suggests keeping caffeine earlier in the afternoon when it affects sleep. If you have an allergy, use medicines, or have a health condition, review our mushroom coffee safety guide and speak with a clinician about your situation.
Does mushroom coffee spike cortisol?
The available material here does not provide a human study of a mushroom-coffee product measuring cortisol. It also does not establish that the mushroom blend offsets caffeine’s effects for an individual. Keep the question practical: compare the listed caffeine with your usual coffee, and pay attention to how caffeine affects your sleep and daily routine.
What doctors and regulators say about the claims
Harvard Health’s reviewed explainer draws a clear line between promising mushroom research and a finished coffee drink: results from test tubes or animals may not apply to people, and they may not remain the same after mushrooms are processed and blended into coffee.
Regulators also matter when marketing moves from general wellness language to disease claims. In a November 5, 2020 warning letter, the FDA’s Quten warning letter explains that disease-treatment claims can cause products to be regulated as drugs under section 201(g)(1)(B) of the Federal Food, Drug, and Cosmetic Act. As of October 15, 2026, that is useful context for reading bold product claims; it is information, not legal advice.
Before you decide
- Check the caffeine number for the exact roast and product.
- Look for species names, extract details, and the amount of each mushroom.
- Compare the current price with servings to get cost per cup.
- Decide whether you want a nutty or earthy coffee profile.
- Read the evidence summary with its clearly marked unknowns before treating a marketing claim as a product result.
The next step is simple: use the current label to compare caffeine, extract detail, taste, and cost per cup, then choose the option that fits your coffee routine.
