Mushroom coffee is worth it if you like how it tastes and don’t mind paying more, but it is not worth it for the health benefits people advertise. Cleveland Clinic and Harvard Health both say there is little human research on mushroom coffee itself, so you would be paying extra for promises nobody has tested in the finished drink. Below you’ll find what reviewers say, the real downsides, why it can make you feel off, and how to compare labels yourself.

Is mushroom coffee really worth the money?
Two big medical sources have weighed in, and they land in a similar place.
- Cleveland Clinic (March 2023 article): registered dietitian Beth Czerwony says mushroom coffee tastes much like regular coffee, because it is coffee with mushroom extract blended in. It costs about double the average coffee. Given the lack of research, she isn’t inclined to recommend it, and says you’d probably do better putting whole mushrooms in your food. She also says there’s “really nothing wrong with mushroom coffee” as long as you aren’t adding lots of sugar or creamer.
- Harvard Health (June 2024 article): the answer to “is it worth a try?” is “maybe.” Studies in test tubes and animals look promising for medicinal mushrooms, but well-designed human trials are lacking, and none were done on mushroom coffee. Harvard adds that you probably won’t do harm by swapping your usual cup, if you don’t mind paying extra, but a side of shiitakes with your eggs would give you fiber and few calories.
The core problem is simple. Both sources say we can’t assume a mushroom’s benefits survive drying, extraction and blending into coffee. Ingredient research is not proof that a finished coffee does anything for you.
What does the Lion’s Mane research actually show?
Brands often market Lion’s Mane for focus. One small 2025 study gave 18 adults 3 g of a 10:1 fruiting-body extract in a single dose. It found no significant overall effect on cognition or mood, with a signal on one isolated task. That is a single small, short study using 3 g of extract. It tells you the research is early, not that Lion’s Mane “doesn’t work.” For a plain-language primer on reading findings like this, see Understanding Emerging Research.
What do mushroom coffee reviews say?
Reviews are personal and mostly about taste, caffeine and texture. Treat them as experiences, not evidence that a product works. Some notes from the pages that rank for this search:
| Brand | What reviewers and roundups say |
|---|---|
| RYZE | A Spoon University student writer found it earthy and a bit grainy (instant only), said it took time to adjust to the lower caffeine, and credited it for fewer sugar cravings and better digestion. Kaffico’s roundup lists six mushrooms, 2,000 mg per serving and about 48 mg of caffeine; Neubrain’s page says the individual doses are unclear. |
| Four Sigmatic | The same student said it tastes like coffee and comes in instant, ground and pod formats. Kaffico lists 250 mg each of Lion’s Mane and Chaga fruiting-body extract in its Focus ground coffee. |
| MUD\WTR | The student reviewer didn’t like the taste and felt tired on the low caffeine, calling it more tea than coffee. A Sunset writer who spent a week on it liked it, felt focused, and noted a silty texture. Sunset says it may earn a commission on purchases. |
| Everyday Dose | Kaffico lists about 45 mg of caffeine, collagen and L-Theanine, not vegan, and says individual doses aren’t disclosed. Neubrain’s page says the coffee flavor can be weak and that cancelling a subscription is tricky. |
One caution on “top 5” and “ranked” lists: several are written by a brand that ranks itself first. Kaffico’s roundup puts its own coffee at #1, and Neubrain’s ranking page says outright, “we are Neubrain.” Their taste and ingredient comments can still be useful, but you should check any claim against the product’s own label.
What is the downside of mushroom coffee?
| Downside | What to know |
|---|---|
| Price | Cleveland Clinic says it costs about double regular coffee. |
| Thin evidence | Harvard Health and Cleveland Clinic both say human research on the finished coffee is lacking. |
| Digestive upset | Cleveland Clinic says mushrooms can sometimes cause digestive issues, especially if you have kidney problems or trouble with grains. |
| Kidney stones and Chaga | Cleveland Clinic says Chaga is high in oxalates and is known to increase kidney stones. Published case reports also describe a possible kidney risk from heavy Chaga use. |
| Medications | Pilly Labs’ own safety notice says functional mushrooms may interact with blood thinners, blood-sugar drugs, blood-pressure drugs, immunosuppressants, sedatives and others, and that people who are pregnant, nursing or about to have surgery should check with a clinician first. Other brands may have similar cautions. |
| Taste and texture | Reviewers describe some blends as earthy or gritty. |
| Hidden amounts | Some products list mushrooms inside a blend without saying how much of each is in it. |
If any of the medication or condition rows sound like you, ask your clinician or pharmacist before you start. Our mushroom coffee safety guide goes through who should be careful.
Why do I feel weird after drinking mushroom coffee?
The most likely reasons are ordinary ones, and none of them needs a mushroom to explain.
- Caffeine changed. Caffeine varies a lot between products. Kaffico’s roundup says ground mushroom coffees run roughly like regular coffee, while some instant blends are closer to 45 to 48 mg. If you cut your usual caffeine, headaches and tiredness can follow. MUD/WTR recommends heavy coffee drinkers wean off gradually instead of stopping at once. If you did the opposite and switched to a stronger blend, jitters are possible. The FDA has a consumer guide on how much caffeine is too much.
- Your stomach. Cleveland Clinic says mushrooms can cause digestive issues for some people.
- New ingredients all at once. Cleveland Clinic’s dietitian suggests trying one type of mushroom powder at a time and tracking any symptoms.
- Sugar or creamer. What you add to the cup matters too.
If you feel unwell, stop and talk to a healthcare provider. The seller notice on Pilly Labs’ site says to discontinue use after an adverse reaction and mentions you can report it to the FDA at safetyreporting.hhs.gov or 1-800-FDA-1088. Individual experiences vary, and no outcome or timeline is guaranteed. Our mushroom coffee vs regular coffee comparison covers caffeine side by side.
Does mushroom coffee reduce belly fat?
No evidence says it does. Harvard Health notes that some brands claim mushroom coffee helps weight loss by boosting metabolism and promoting fat burning, but there is very little human research on medicinal mushrooms, and none on mushroom coffee. Cleveland Clinic’s article on green coffee bean extract, a different supplement, says there’s no evidence it helps with weight loss and that it may carry risks.
What drink burns the most belly fat, or gets a flat tummy in 3 days?
Neither of the two medical sources covers a drink that targets belly fat or shrinks it in days, so any page promising that is going beyond the research. The same goes for dropping 20 pounds quickly. For a weight goal, the safest move is to ask your doctor or a registered dietitian for a plan that fits your health, medications and timeline. Mushroom coffee isn’t a substitute for that.
What does the Mayo Clinic say about mushroom coffee?
If you want a medical-center opinion, the two to read are the Cleveland Clinic and Harvard Health pieces summarized above. Both are cautious: little human research, higher cost, and whole mushrooms as the better bet for nutrition.
How do I pick the best mushroom coffee for health?
No one can name a “best” for health, because no mushroom coffee has been shown to improve health. What you can do is pick the best match for criteria that matter to you. Here are the ones this page uses, and what to check on the label or product page:
| If you care about… | Check this |
|---|---|
| Knowing what you’re getting | Whether each mushroom has its own stated amount, or sits inside a blend with no breakdown. |
| Caffeine | Milligrams per serving. If it isn’t listed, ask the seller before ordering. |
| Taste and texture | Ground, instant or pods. Reviewers describe instant blends as grainier and some as earthy. |
| Sugar | Added sugars and sweeteners in the supplement facts, plus what you stir in. |
| Mushroom form | Whether the label says fruiting body extract, mycelium, or plain powder. Sellers argue about which is better, so judge by what is stated. |
| Safety | Chaga and kidney stones, medications, pregnancy, allergies. Check with your clinician. |
| Testing or certification claims | Only count them if the brand names the lab, the product and the date. A bare “tested” is not a document. |
As an example of a label that states its split, Pilly Labs’ Vitality Mushroom Coffee is a medium-roast ground coffee listed as 90% Arabica, 5% Lion’s Mane and 5% Chaga. In a 10 g tablespoon that works out by simple ratio to about 500 mg of each mushroom, with 0 g sugar and 34 servings in the 12 oz bag. That’s one data point for comparing labels, not proof it does anything. The caffeine per serving is the figure to confirm with support before you order, and nothing about it has been shown to improve focus, immunity or anything else. Our Vitality caffeine and sensitivity guide covers that question, and the label worksheet lets you run the same checks on any brand.
Before you order
- Ask the seller for the per-serving caffeine amount if the label doesn’t show it.
- Look for per-mushroom amounts. If they’re not given, you can’t compare the product to any study.
- Check any “lab tested” claim for a named lab, product and date.
- If you have kidney stones, take medications, are pregnant or nursing, or have surgery coming up, ask a clinician first.
- Check the current price, refund window and subscription terms at checkout before you pay.
