Mushroom Coffee: Potential Health Benefits and Drawbacks
If you have scrolled through social media or visited a health food shop recently, you have likely encountered the growing trend of mushroom coffee. It is marketed as a healthier alternative to your standard morning brew, promising distinct advantages ranging from improved focus to enhanced immunity.
While the concept of mixing fungi with coffee beans might sound unappealing to some, or simply strange to others, the practice is rooted in a long history of medicinal mushroom use. Proponents claim it offers the wakefulness of caffeine without the jittery side effects.
However, distinguishing between marketing hype and scientific reality is essential. This article explores the evidence behind mushroom coffee, analysing its ingredients, potential benefits, and downsides to help you decide if it is worth the switch.
Overview
Mushroom coffee is not simply a cup of hot water with floating mushrooms. Rather, it is a delicate blend of ground coffee beans and medicinal mushroom extracts.
Generally, the mushrooms are dried, extracted, and ground into a fine powder. This powder is then mixed with ground coffee beans, typically in a ratio of 1:1 or with a lower concentration of mushrooms. The result is a dark, smooth powder that looks and smells much like regular coffee.
Most blends use Arabica coffee beans, known for their smoother flavour profile, to mask the earthy, savoury taste of the fungi. When prepared, the taste is often described as nutty or smooth, rather than distinctly "mushroom-like".
These beverages often fall into the category of "functional foods"—ingredients that offer health benefits beyond basic nutrition. The mushrooms utilised are not the culinary varieties like button or portobello mushrooms, but rather functional mushrooms known as adaptogens.
Adaptogens are natural substances that are believed to help the body adapt to stress and exert a normalising effect upon bodily processes. This unique combination of caffeine and adaptogens is the primary selling point for most brands.
Causes and Factors: What Goes Into the Brew?
To understand the potential effects of this beverage, one must examine the specific factors that differentiate it from standard coffee. The primary factor is the inclusion of medicinal fungi, each selected for specific properties.
Key Ingredients
The most common mushrooms found in these blends include:
- Chaga (Inonotus obliquus): Often harvested from birch trees in cold climates, Chaga is rich in antioxidants. It has been used traditionally to support immune function.
- Lion’s Mane (Hericium erinaceus): This shaggy, white mushroom is famed for its potential neuroprotective properties. It is often the primary ingredient in blends marketed for focus and concentration.
- Reishi (Ganoderma lucidum): Known as the "king of mushrooms", Reishi is traditionally used to support sleep and reduce stress, helping to balance the stimulating effects of caffeine.
- Cordyceps (Cordyceps sinensis): Historically used by athletes, Cordyceps is believed to support energy levels and oxygen utilisation.
The Caffeine Factor
A significant factor driving the popularity of mushroom coffee is its reduced caffeine content. Because the coffee grounds are diluted with mushroom powder, a cup typically contains about half the caffeine of a regular cup of coffee.
For individuals who are sensitive to caffeine, this can be a major advantage. It allows for the ritual of drinking coffee without the anxiety, palpitations, or sleep disruption often associated with high caffeine intake.
According to Mayo Clinic, limiting caffeine is crucial for those with anxiety disorders or heart conditions. Mushroom coffee offers a middle ground between full-strength coffee and decaf.
Extraction Methods
The method of processing is a critical factor in the quality of the product. The medicinal compounds in mushrooms, such as beta-glucans, are locked within chitin cell walls, which humans cannot digest.
Therefore, reputable brands use a dual-extraction process (hot water and alcohol extraction) to make these compounds bioavailable. When choosing a product, checking for "dual-extracted" on the label is a vital factor for ensuring efficacy.
Treatment and Management: Benefits vs. Drawbacks
While mushroom coffee is not a medical treatment, it is often used as a dietary management tool for energy and focus. The interplay between the benefits and potential drawbacks is complex and worth examining in detail.
Potential Health Benefits
1. Smoother Energy Levels
Many users report that mushroom coffee provides a more sustained release of energy compared to standard coffee. This is likely due to the lower caffeine content combined with adaptogens.
Unlike the sharp spike and subsequent crash often associated with espresso, the energy from mushroom blends tends to be more stable. This can be particularly helpful for managing afternoon fatigue.
2. Immune System Support
Mushrooms like Chaga and Turkey Tail are rich in beta-glucans and other polysaccharides. Research suggests these compounds can modulate the immune system.
A study highlighted by the National Institutes of Health indicates that Chaga extract may reduce inflammation and fight bacteria, though more human trials are needed.
3. Cognitive Support
Lion’s Mane is the star ingredient for brain health. Animal studies have shown that it may increase the production of Nerve Growth Factor (NGF), which is essential for the growth and survival of neurons.
While human research is in its early stages, some evidence suggests it may improve mild cognitive impairment. You can read more about these cognitive links at Healthline.
4. Stress Reduction
Adaptogens like Reishi help the body manage cortisol levels. By pairing a stimulant (coffee) with a relaxant (Reishi), the beverage attempts to neutralise the physical stress response.
This "stacking" of supplements is a common strategy in biohacking communities for managing high-stress lifestyles. The Cleveland Clinic provides further context on how adaptogens function in the body.
Drawbacks and Risks
1. Limited Human Research
The most significant drawback is the lack of large-scale clinical trials on mushroom coffee specifically. Most claims are based on studies of individual mushrooms in isolated, high-dose forms—often in test tubes or rodents.
It is unclear if the smaller amounts of mushroom extract found in a single cup of coffee are sufficient to produce the same medicinal effects seen in clinical settings.
2. Digestive Issues
Mushrooms naturally contain complex carbohydrates and fibres that can be difficult for some people to digest. Individuals with sensitive stomachs or Irritable Bowel Syndrome (IBS) may experience bloating or gas.
Furthermore, Chaga is high in oxalates. As noted by WebMD, high oxalate intake can increase the risk of kidney stones in susceptible individuals. Those with a history of kidney issues should manage their intake carefully.
3. Cost
Mushroom coffee is significantly more expensive than regular ground coffee. The processing, extraction, and sourcing of medicinal mushrooms drive up the price, often costing two to three times more per cup.
4. Safety for Specific Groups
Because adaptogens interact with the immune system and hormonal pathways, they may not be safe for everyone. Pregnant or breastfeeding women, and those with autoimmune diseases, should consult a GP before consumption.

Practical Tips
If you are interested in trying mushroom coffee, integrating it into your routine requires some thought to ensure you get the best value and results.
How to Choose a Brand
Not all products are created equal. The supplement market is loosely regulated, so quality assurance is paramount. Look for brands that provide a Certificate of Analysis (COA) or third-party testing.
Check the label for "fruiting body" extracts. Some cheaper brands use "mycelium on grain," which is essentially the root system of the mushroom grown on rice. This contains significantly fewer beneficial compounds like beta-glucans than the actual mushroom cap (fruiting body). See this study on beta-glucan potency at the National Institutes of Health.
Preparation Methods
Mushroom coffee is versatile. You can buy it as:
- Instant sachets: Just add hot water. Great for travel.
- Ground blends: Brew in a cafetière, filter machine, or pour-over just like regular coffee.
- Pods: Available for various coffee pod machines.
Avoid using boiling water directly on the powder if possible; slightly cooler water (around 90°C) is less likely to scorch the coffee or degrade delicate compounds.
Dosage and Timing
Start with one cup per day to monitor how your body reacts. Because it contains less caffeine, you might be tempted to drink more, but remember that the dosage of medicinal mushrooms will also increase.
- For Focus: Drink a blend with Lion's Mane in the morning. See research on Lion's Mane at the National Institutes of Health.
- For Pre-Workout: Try a Cordyceps blend 30 minutes before exercise. Evidence on Cordyceps and performance can be found at the National Institutes of Health.
- For Relaxation: A Reishi blend is best consumed in the late afternoon. National Institutes of Health studies suggest Reishi may help with sleep cycles.
Enhancing the Flavour
If the earthy taste is too strong for you, treat it like a latte. Adding a splash of oat milk or almond milk can complement the nutty profile of the mushrooms.
A dash of cinnamon or cacao can also mask any lingering savoury notes. Interestingly, the lower acidity of mushroom coffee often makes it easier to drink black than cheaper supermarket coffees.
Who Should Avoid It?
Always consult a healthcare professional before adding potent supplements to your diet. Specifically:
- Autoimmune Conditions: Mushrooms like Reishi stimulate the immune system, which could worsen conditions like lupus or rheumatoid arthritis.
- Bleeding Disorders: Some mushrooms have blood-thinning properties.
- Surgery: Stop consumption at least two weeks before scheduled surgery.

The Bottom Line
Mushroom coffee is an intriguing blend of ancient herbal wisdom and modern dietary habits. It offers a promising alternative for those seeking to lower their caffeine intake while potentially gaining extra nutritional support.
The inclusion of functional mushrooms like Lion's Mane and Chaga provides antioxidants and adaptogens that may support the immune system and cognitive function. However, current claims rely heavily on animal studies and isolated extracts rather than comprehensive trials on the coffee blends themselves.
If you suffer from caffeine jitters, acidity, or digestive discomfort from regular coffee, this could be a worthwhile swap. However, it is an expensive habit compared to standard beans.
Ultimately, while it is not a magic cure-all, it is a safe and potentially beneficial beverage for most healthy adults. As with any wellness trend, listen to your body and prioritise a balanced diet alongside your morning brew.
Should you decide to try it, opt for high-quality, dual-extracted products using fruiting bodies to ensure you are getting the medicinal compounds you are paying for.
