What Is Mushroom Coffee? Benefits, Caffeine & Taste

What is actually in mushroom coffee?

Mushroom coffee combines two components: ground coffee beans (usually medium-roast Arabica) and dried, concentrated mushroom extract powder. The mushroom component is not raw mushroom sliced into your cup. It is a hot-water or dual-extracted (water + alcohol) concentrate of one or more medicinal mushroom species, processed into a fine, dissolvable powder that blends into brewed coffee without altering the texture.

Jeff Chilton, founder of Nammex and one of the most-cited authorities on mushroom quality standards, published a 2017 analysis demonstrating that mycelium-on-grain products contained significantly lower beta-glucan concentrations and higher starch content than fruiting body extracts: a finding that fundamentally reshaped how informed buyers evaluate mushroom supplements.

The most commonly included species serve distinct functional roles. Lion's mane (Hericium erinaceus) is included for cognitive support. It contains unique compounds called hericenones and erinacines that stimulate nerve growth factor (NGF) production in the brain. Chaga (Inonotus obliquus) contributes antioxidant compounds, including melanin and polyphenols that have demonstrated free-radical scavenging activity in laboratory testing. Reishi (Ganoderma lucidum) brings immune-modulating beta-glucans and triterpenes, plus a calming quality that partially offsets coffee's stimulatory effects. Cordyceps (Cordyceps militaris) is the energy species. It is associated with improved oxygen utilization and reduced fatigue during physical activity.

Some formulations also include turkey tail (Trametes versicolor), maitake, or shiitake for additional beta-glucan diversity. The quality differences between brands come down to three variables: whether they use fruiting body extract, mycelium-on-grain, or a combination; the extraction method (hot water vs dual extraction); and the per-species dosing transparency. A label that lists "proprietary mushroom blend 250 mg" tells you very little. A label that lists each species with its individual milligram count gives you substantially more information to evaluate.

The finished product tastes like coffee. Slightly earthier, occasionally nuttier, but recognizably coffee. The mushroom compounds dissolve invisibly. There is no gritty texture, no mushroom broth flavor, no visible particles floating in the cup.

Does mushroom coffee have caffeine?

Yes. Because mushroom coffee contains real coffee beans, it contains real caffeine. A standard single-serving packet delivers approximately 50–60 mg of caffeine per cup, roughly half the caffeine content of a standard brewed coffee (100–150 mg) and comparable to a single shot of espresso.

The reduction is intentional, not incidental. Most brands formulate their blends at a 1:1 ratio of coffee to mushroom powder, which mechanically halves the amount of coffee per serving. The functional premise behind this is that compounds in lion's mane and cordyceps provide sustained mental clarity and energy support through mechanisms that differ from caffeine (NGF stimulation and improved cellular ATP production, respectively) so you get the alertness without as much dependence on the caffeine molecule itself.

In practical terms, this makes mushroom coffee a useful tool for people in one of three situations. First, the person currently drinking two to four cups of regular coffee who wants to cut back without going cold turkey. Second, the person who is caffeine-sensitive and gets jitters, anxiety, or disrupted sleep from a full-strength cup. Third, the person who wants afternoon coffee without the risk of it interfering with sleep later that night. If you need to be completely caffeine-free (for medical reasons or personal preference) mushroom coffee is not the answer. Standalone mushroom extract capsules or mushroom-infused teas without a coffee base would be more appropriate alternatives.

One nuance worth noting: not all mushroom coffees have the same caffeine content. Some brands use a higher coffee-to-mushroom ratio, which pushes caffeine closer to 80–90 mg. Others offer fully decaffeinated versions. Always check the label or the brand's FAQ page for the specific caffeine content per serving.

What does mushroom coffee taste like?

If someone handed you a cup of well-made mushroom coffee without disclosing its contents, you would almost certainly assume you were drinking regular coffee. The flavor difference is subtle, a slightly earthier finish, sometimes a faint nuttiness, occasionally a mild woodsy note depending on the mushroom species in the blend. You are not drinking a mushroom broth. You are drinking coffee that happens to contain dissolved functional compounds from mushroom extracts.

This matters because taste anxiety is the single largest barrier for first-time buyers. Consumer survey data consistently shows that people who have never tried mushroom coffee overestimate how "mushroomy" it will taste, while those who have tried it describe the flavor as essentially indistinguishable from a standard cup of coffee, especially when prepared with milk, cream, or a sweetener.

The type of mushroom extract in the blend does create minor flavor variations. Lion's mane tends to be the most flavor-neutral. Chaga adds subtle vanilla-like undertones from its melanin and polyphenol content. Reishi can introduce a faint bitterness if over-dosed. Cordyceps is mild and largely undetectable. The coffee base itself (the origin, roast level, and grind) has a far larger impact on the final flavor than the mushroom component does.

Our Vitality Mushroom Coffee uses a medium-roast Arabica base specifically selected to complement the earthiness of the mushroom blend. The result is a smooth, balanced cup that works equally well black, with oat milk, or blended into a latte.

Is mushroom coffee good for you? What the research shows for each species

The honest answer depends on which mushroom species you are evaluating, and at what dose. "Mushroom coffee" is a product category, not a single compound, and the clinical evidence varies substantially from one species to another. Robert Beelman, Ph.D., Professor Emeritus of Food Science at Penn State University and a leading researcher on mushroom bioactives, has noted that mushrooms contain unique antioxidant compounds like ergothioneine that are not found in most other foods, positioning certain species as genuinely functional ingredients rather than marketing novelties.

Here is what the human evidence actually says, species by species.

Lion's mane (Hericium erinaceus) — cognitive support

Lion's mane has the most developed clinical evidence among mushroom coffee ingredients. The landmark study is a 16-week double-blind, placebo-controlled RCT by Mori et al. (2009) in 30 older Japanese adults with mild cognitive impairment. Participants receiving 3,000 mg/day of lion's mane showed statistically significant improvement on cognitive function scales compared to placebo, but this improvement reversed within four weeks of stopping supplementation, suggesting the effect requires ongoing intake (PMID: 18844328).

A 2023 double-blind pilot study by Docherty et al. at Northumbria University tested 1,800 mg/day in healthy young adults (ages 18–45) and found faster performance on the Stroop task 60 minutes after a single dose, plus a trend toward reduced subjective stress after 28 days — though the sample was small (n=41) and some endpoints were null (PMID: 37960217).

A 2025 systematic review by Menon et al. pooled data across multiple trials and found a weighted mean increase of 1.17 points on Mini-Mental State Examination scores in intervention groups, supporting a modest but measurable cognitive benefit (PMID: 40959699). The mechanism involves hericenones (found in the fruiting body) and erinacines (found in the mycelium) stimulating NGF synthesis, which supports neuronal growth and maintenance.

Chaga (Inonotus obliquus) — antioxidant defense

Chaga's reputation as an antioxidant powerhouse is grounded in measurable chemistry. Its ORAC (Oxygen Radical Absorbance Capacity) value has been measured at up to 146,700 µmol TE/100g. Substantially higher than acai, blueberries, or dark chocolate. The primary antioxidant compounds are melanin pigments, polyphenols including hispidin and its derivatives, and the enzyme superoxide dismutase (SOD).

In a cell-based study by Park et al. (2004), aqueous chaga extract demonstrated a dose-dependent protective effect against hydrogen peroxide-induced oxidative DNA damage in human lymphocytes, as measured by the comet assay (PMID: 15630179). Lee et al. (2007) isolated novel antioxidant polyphenols (inonoblins A, B, and C) from chaga and confirmed significant scavenging activity against ABTS and DPPH radicals (PMID: 17980585).

The limitation: nearly all chaga research is preclinical. There are no published human RCTs testing chaga as a standalone supplement for specific health outcomes. The antioxidant capacity is well-documented in laboratory assays, but whether that translates to measurable clinical benefit at the doses found in mushroom coffee remains unproven.

Reishi (Ganoderma lucidum) — immune modulation

Reishi has the longest track record of traditional use (more than 2,000 years in Chinese and Japanese medicine) and its immune-modulating properties have the strongest mechanistic explanation among functional mushrooms. The key bioactive compounds are beta-glucan polysaccharides and triterpenes (ganoderic acids), which interact with pattern recognition receptors on immune cells to modulate both innate and adaptive immune responses.

A 2023 randomized, double-blinded, placebo-controlled trial by Chen et al. gave healthy adults (ages 18–55) reishi-derived beta-glucan daily for 84 days and measured significant enhancement of CD3+, CD4+, CD8+ T-lymphocyte populations, improved CD4/CD8 ratio, increased natural killer cell counts, and elevated serum immunoglobulin A, with no adverse changes in kidney or liver function markers (PMID: 36766186).

A separate safety-focused RCT by Wachtel-Galor et al. confirmed that 4 g/day of reishi extract for 10 days produced no adverse effects compared to placebo in healthy volunteers, while noting an increase in CD56+ natural killer cells during the supplementation period (PMID: 17597499).

Cordyceps (Cordyceps militaris) — energy and endurance

Cordyceps is the performance mushroom. A 2017 randomized, double-blind, placebo-controlled study by Hirsch et al. found that 4 g/day of a Cordyceps militaris-containing mushroom blend for three weeks significantly improved VO2max (+4.8 ml·kg⁻¹·min⁻¹, p=0.042) and time to exhaustion in young, healthy adults during cycle ergometer testing. The placebo group showed negligible change (PMID: 27408987).

The proposed mechanism involves cordycepin (3'-deoxyadenosine) stimulating mitochondrial ATP production through AMPK pathway activation, providing energy at the cellular level rather than through central nervous system stimulation the way caffeine does. This is why cordyceps and caffeine are often described as complementary. They support alertness and physical performance through entirely different biochemical pathways.

Does mushroom coffee actually work? The honest counter-argument

Fair question, and it deserves a direct answer: the evidence supports the mushroom ingredients, but not necessarily the mushroom coffee product format at the doses most brands deliver.

Here is the arithmetic that rarely appears in marketing copy. The lion's mane RCT by Mori et al. used 3,000 mg/day. The cordyceps study by Hirsch et al. used 4,000 mg/day of a mushroom blend. The reishi immune trial by Chen et al. used purified beta-glucan from reishi daily for 84 days. A typical mushroom coffee serving contains a total of 100–500 mg of a multi-species blend, meaning each individual species might contribute 25–125 mg per cup. That is, at best, a fraction of studied doses. Some researchers, including nutritionist Marta Marcè, have pointed out that most mushroom coffees on the market include between 250 mg and 500 mg of total extract per cup, far below the doses used in studies that observed real benefits.

Additionally, Harvard Health has raised the question of whether processing mushrooms into extracts and brewing them into coffee preserves the same bioactive properties that were demonstrated in controlled supplementation studies. The extraction method matters: hot-water extraction is effective for beta-glucans (which are water-soluble), but may miss fat-soluble triterpenes that require alcohol extraction. Mycelium-on-grain products: where the mushroom is grown on a grain substrate and the entire mass is ground up. May contain significant amounts of starch filler and lower concentrations of target compounds compared to pure fruiting body extracts.

None of this means mushroom coffee is worthless. It means the honest framing is: mushroom coffee is a convenient way to introduce functional mushroom compounds into your daily routine at sub-clinical doses. If your primary goal is cognitive enhancement at clinically-validated levels, standalone lion's mane capsules at 1,000–3,000 mg/day would be more appropriate. If your goal is to drink less caffeine, get some exposure to adaptogenic compounds, and enjoy a good cup of coffee. Mushroom coffee delivers on all three.

Does mushroom coffee help you lose weight?

There is no published clinical trial showing that drinking mushroom coffee causes weight loss. Some brands market mushroom coffee as metabolism-boosting or fat-burning, but these claims are not supported by direct evidence from human studies on mushroom coffee as a product.

What is indirectly relevant: reducing caffeine intake can lower cortisol fluctuations that promote visceral fat storage. Reishi has been studied in animal models for its potential effects on gut microbiota composition and body weight regulation. Cordyceps has shown anti-fatigue effects that might support more consistent exercise habits. These are plausible mechanisms, not proven outcomes of drinking mushroom coffee specifically.

The most practical weight-related benefit may be the simplest: if mushroom coffee helps you stop adding a second or third high-calorie coffee drink to your day (because the first one provides sustained alertness without a crash), the net calorie reduction could support weight management. That is a behavioral outcome, not a pharmacological one.

Is mushroom coffee good for your liver?

Several of the mushroom species commonly found in mushroom coffee have shown hepatoprotective (liver-protective) properties in preclinical studies. Chaga extracts have demonstrated the ability to reduce liver enzyme markers in animal models of chemically-induced liver injury. Reishi triterpenes (particularly ganoderic acids) have been studied for their potential to support liver cell regeneration and reduce fibrotic changes in rodent models. A 2024 review in Biomedicine & Pharmacotherapy catalogued over a dozen animal studies showing reishi polysaccharides reduced oxidative stress markers and inflammatory cytokines in liver tissue.

However, these results come from isolated mushroom extracts given at specific doses to animals, not from mushroom coffee consumed by humans. No clinical trial has tested whether drinking mushroom coffee improves liver function in healthy adults or in populations with liver concerns. The safety data from reishi human trials (such as PMID: 17597499) showed no negative impact on liver enzymes, which is reassuring but not the same as demonstrating a therapeutic benefit.

If you have an existing liver condition, talk to your physician before adding mushroom coffee to your routine, not because it is known to be harmful, but because some mushroom species can interact with medications metabolized by the liver.

Does mushroom coffee make you poop?

Some people report increased bowel regularity when they start drinking mushroom coffee. Two plausible mechanisms explain this. First, mushroom coffee still contains caffeine, which stimulates gastric motility and colonic contractions. The same reason regular coffee sends some people to the bathroom. Second, the beta-glucan polysaccharides in mushroom extracts function as prebiotic fibers that feed beneficial gut bacteria and can promote stool bulk and regularity.

A 2025 study published in the Journal of Functional Foods by M2 Ingredients found that Cordyceps militaris whole-mushroom powder outperformed inulin (a gold standard prebiotic) in stimulating butyrate production during in vitro fermentation. Butyrate is a short-chain fatty acid critical for colon health, gut barrier integrity, and anti-inflammatory signaling in the gut lining.

On the flip side, some individuals experience mild digestive discomfort (gas, bloating, or loose stools) particularly during the first week of consumption. This is generally a microbiome adjustment response and tends to resolve within 5–7 days. Starting with half a serving for the first few days can help minimize initial GI effects.

Is mushroom coffee acidic?

Mushroom coffee is generally less acidic than regular coffee, though it is not pH-neutral. Standard brewed coffee has a pH of approximately 4.85–5.10. Mushroom coffee, because it replaces a portion of the coffee grounds with mushroom extract powder (which is closer to neutral pH), typically measures 5.0–5.5: a modest but potentially meaningful reduction for people with acid reflux, GERD, or sensitive stomachs.

Reishi and chaga extracts, specifically, have shown gastroprotective properties in preclinical models. A 2018 study found that chaga polysaccharides reduced gastric mucosal injury in ethanol-challenged rats, suggesting a protective effect on the stomach lining: though this has not been tested in the context of coffee consumption in humans.

If acid reflux is your primary reason for switching from regular coffee, mushroom coffee may offer marginal improvement. But it is not acid-free. A cold-brew preparation method (regardless of whether mushrooms are included) typically achieves a greater pH shift than the mushroom substitution alone.

Does mushroom coffee break a fast?

It depends on which definition of "fasting" you are using. For strict water-only fasting, any caloric intake (including the 5–15 calories in a serving of mushroom coffee) technically breaks the fast. For the more common time-restricted eating protocols (like 16:8 intermittent fasting), mushroom coffee is generally considered acceptable because its caloric content is minimal and its impact on insulin is negligible.

Black mushroom coffee (no milk, no sweetener) contains roughly 5–15 calories per serving, primarily from the mushroom extract powder. This is comparable to or slightly higher than black regular coffee (approximately 2–5 calories). The small calorie difference is unlikely to meaningfully disrupt the metabolic benefits that most people are seeking from intermittent fasting, including autophagy promotion and insulin sensitivity improvement.

The beta-glucans and polyphenols in mushroom extracts may actually complement fasting goals by supporting gut barrier function and reducing inflammation during the fasting window. For a deeper analysis, see our full article on whether mushroom coffee breaks a fast.

How to make mushroom coffee at home

The simplest method is to use a pre-mixed mushroom coffee product: instant packets or ground blends that already combine the coffee and mushroom components. Brew exactly as you would regular coffee: pour hot water over an instant packet, use a drip brewer with ground blend, or prepare in a French press. No special equipment is needed.

If you prefer to build your own, start with your favorite medium-roast coffee (brewed however you normally make it) and stir in 500–1,000 mg of a high-quality mushroom extract powder. Lion's mane extract for cognitive focus or a multi-species blend for broader coverage are both good starting points. Use hot-water-extracted or dual-extracted powders, not raw mushroom powder, which has poor bioavailability because the bioactive compounds are locked behind chitin cell walls that human digestion cannot efficiently break down.

For a mushroom coffee latte, brew a strong serving (double the coffee concentration), add 6–8 oz of steamed oat milk or whole milk, and optionally blend in a teaspoon of MCT oil or coconut cream for a richer texture. The fat source also helps with the absorption of fat-soluble mushroom triterpenes. A pinch of cinnamon or a small drizzle of raw honey complements the earthy notes without masking them.

Mushroom coffee side effects and who should be cautious

For the majority of healthy adults, mushroom coffee at standard serving sizes is well-tolerated. The most commonly reported side effects are mild and digestive: temporary bloating, gas, or changes in bowel habits during the first week of use as the gut microbiome adjusts to the prebiotic beta-glucan content.

Beyond the mild GI adjustment, specific populations should exercise caution or avoid mushroom coffee entirely:

Kidney disease or history of kidney stones. Chaga mushroom contains elevated levels of oxalates: compounds that bind to calcium and can contribute to kidney stone formation. While the oxalate content in a single serving of mushroom coffee is low (estimated at 1.5–2.5 mg per serving according to some manufacturers), cumulative daily intake is a consideration for anyone with existing kidney concerns or oxalate sensitivity.

Blood-thinning medications. Both reishi and chaga contain compounds with mild anticoagulant properties. Reishi triterpenes can inhibit platelet aggregation, and chaga contains proteins that interfere with blood clotting pathways. Anyone taking warfarin, heparin, aspirin, or other anticoagulant medications should consult their physician before adding mushroom coffee to their routine, and should discontinue it 7–14 days before any scheduled surgery.

Immunosuppressant therapy. Because reishi, turkey tail, and other mushroom species actively stimulate immune cell proliferation, they may theoretically interfere with immunosuppressant medications prescribed for organ transplant recipients or individuals managing autoimmune conditions. This has not been tested in clinical settings, but the theoretical risk is sufficient to warrant medical consultation.

Pregnancy and breastfeeding. There is insufficient safety data on functional mushroom supplementation during pregnancy or breastfeeding. Most healthcare providers recommend avoidance as a precautionary measure. The caffeine content alone warrants monitoring during pregnancy regardless of the mushroom component.

Mushroom allergies. Individuals with known allergies to any mushroom species should avoid mushroom coffee. Cross-reactivity between species is possible, and concentrated extracts may trigger reactions in individuals who tolerate whole culinary mushrooms without issue.

Diabetes medications. Some mushroom species (particularly reishi and cordyceps) have demonstrated blood glucose-lowering effects in preclinical models. For individuals managing diabetes with medication, the combination could theoretically increase hypoglycemia risk. Blood sugar monitoring is advisable, and medical guidance should be sought before making mushroom coffee a daily habit.

Can you drink mushroom coffee while pregnant?

The safest answer is no, not without explicit guidance from your obstetrician or midwife. The fundamental problem is not that mushroom coffee has been shown to cause harm during pregnancy, but that it has not been studied for safety in pregnant or breastfeeding populations at all. The absence of evidence is not evidence of absence, and most prenatal health guidelines apply a precautionary principle to under-studied supplements.

The caffeine content (50–60 mg per serving) is well within the commonly cited 200 mg/day threshold from the American College of Obstetricians and Gynecologists (ACOG), so the caffeine component alone is unlikely to be problematic for most pregnancies. The concern is the mushroom extract component, specifically, reishi's documented immune-modulating properties and cordyceps' potential effects on hormonal signaling, neither of which has been evaluated in the context of fetal development.

If you are currently pregnant or breastfeeding and want the lower-caffeine benefit of mushroom coffee, a simpler alternative is half-caf or decaf regular coffee. Same caffeine reduction, none of the unknowns from mushroom extract supplementation.

How the four key mushroom species compare

The following infographic breaks down the primary functional mushroom species found in mushroom coffee — their key bioactive compounds, primary researched benefits, and the strength of current human clinical evidence.

Mushroom coffee brands compared: what you are actually getting

Not all mushroom coffees are created equal. The table below compares five widely available brands across the variables that matter most. Mushroom species count, extract type, per-serving mushroom dose, caffeine content, and price per serving. For a more detailed breakdown, see our full best mushroom coffee guide.

Robert Rogers, PhD, a mycologist at the University of Alberta who has published extensively on medicinal mushroom pharmacology, has noted that beta-glucan content is the single most reliable predictor of biological activity across mushroom species, and that products failing to disclose beta-glucan percentages are essentially asking consumers to trust their marketing rather than their chemistry.

Brand	Species	Extract Type	Mushroom Dose	Caffeine	Price/Serving
YourHealthier Vitality	6 species	Dual-extracted fruiting body	2,360 mg	~50 mg	~$1.30
RYZE Superfoods	6 species	Fruiting body + mycelium	2,000 mg	~48 mg	~$1.00
Four Sigmatic Think	2 species	Dual-extracted fruiting body	500 mg	~150 mg	~$1.50
Everyday Dose	2 species	Fruiting body extract	586 mg	~39 mg	~$2.00
MUD\WTR (not coffee)	4 species	Mushroom powder blend	~1,500 mg	~35 mg	~$2.20

Key differentiators to evaluate: mushroom dose per serving (higher is generally better, assuming quality extract), whether the brand discloses per-species dosing or hides behind a proprietary blend, extraction method (dual extraction captures both water-soluble beta-glucans and fat-soluble triterpenes), and whether they use fruiting body, mycelium-on-grain, or a combination. Third-party testing for heavy metals, pesticides, and beta-glucan content verification adds an additional layer of quality assurance.

Inside the mushroom coffee industry

For a broader look at the economics and growth trajectory of the mushroom coffee category (including how brands like RYZE scaled to nine-figure revenue) this CNBC analysis provides useful context on the market dynamics, consumer trends, and competitive environment shaping the industry in 2026.

Pros and cons of mushroom coffee

What mushroom coffee does well: It reduces caffeine intake without requiring you to give up coffee entirely. It introduces bioactive compounds from functional mushrooms into a format that requires zero behavior change. You are still drinking coffee. The taste is virtually identical to regular coffee. Multiple species (lion's mane, reishi, cordyceps) have independently demonstrated beneficial properties in human trials. And it may support gut health through prebiotic beta-glucan content.

Where it falls short: Per-serving mushroom doses are typically below clinically studied thresholds. No RCT has tested mushroom coffee as a finished product. Quality varies enormously between brands, some use mycelium-on-grain with significant starch filler. Price per serving is higher than regular coffee. It is not appropriate for pregnant or breastfeeding individuals, people on blood thinners, or those with kidney disease. And the category's marketing often overstates the evidence, creating expectations that the product may not fully deliver on.

The balanced conclusion: mushroom coffee is a reasonable choice for caffeine reduction combined with modest functional mushroom exposure. It is not a substitute for targeted, full-dose mushroom supplementation, and it is not a medical intervention. If you enjoy coffee and are curious about functional mushrooms, it is worth trying. If you are seeking specific clinical outcomes, standalone mushroom extracts at validated doses are more likely to deliver.

Why YourHealthier

Our Vitality Mushroom Coffee includes six functional mushroom species (lion's mane, chaga, reishi, cordyceps, turkey tail, and maitake) with a total mushroom extract dose of 2,360 mg per serving, which is among the highest in the category. Every batch uses dual-extracted fruiting body mushrooms, not mycelium-on-grain, so you are getting concentrated bioactive compounds rather than starch filler. The coffee base is medium-roast Arabica, and total caffeine per serving is approximately 50 mg. We list the per-species dose on the label because we believe you should know exactly what you are paying for. Pair it with our standalone Lion's Mane capsules if you want to reach clinically-validated cognitive support doses alongside your daily cup.

Who should try mushroom coffee — and who should not

Good fit: People who currently drink regular coffee and want to reduce caffeine intake without going decaf. People curious about functional mushrooms who prefer a food-based format over capsules. People who experience afternoon energy crashes, jitters, or disrupted sleep from regular coffee. Health-conscious consumers looking for antioxidant and adaptogenic compounds in their daily routine.

Not a good fit: People who require zero caffeine intake. People seeking clinical-dose mushroom supplementation for a specific health goal, standalone extracts at 1,000–3,000 mg/day of a single species would be more appropriate. People who do not like coffee, mushroom coffee still tastes like coffee, not like tea or juice. People with kidney disease, mushroom allergies, bleeding disorders, or those taking immunosuppressants, anticoagulants, or diabetes medications without first consulting their physician.
