Who Should Not Drink Mushroom Coffee? (Safety Guide 2025)
The surge in mushroom coffee popularity brings promises of enhanced cognitive function and wellness benefits, but the growing trend also creates risks for people who assume all natural products are universally safe for consumption without considering individual health conditions or medication interactions. Marketing messages emphasizing the natural origins and health benefits of functional mushrooms often overshadow important safety considerations that could affect certain populations, leaving consumers to navigate potential contraindications without adequate guidance. The challenge lies in understanding which individuals should exercise caution or avoid mushroom coffee entirely, especially as the market expands with limited regulation and inconsistent safety information across different brands and products.
Wellness enthusiast Jennifer embraced mushroom coffee as part of her morning routine after reading about its cognitive benefits and energy-boosting properties, assuming that anything labeled as natural and healthy would be safe for her daily consumption. Her excitement turned to concern when she experienced unexpected digestive issues and noticed interactions with her prescription medications that her doctor later explained could be related to the bioactive compounds in functional mushrooms. This experience taught her that even beneficial natural products require careful consideration of individual health circumstances, existing medical conditions, and potential drug interactions that many mushroom coffee enthusiasts overlook in their pursuit of wellness benefits.
Understanding who should avoid or limit mushroom coffee consumption requires examining specific health conditions, medication interactions, and individual sensitivities that can make these popular wellness products problematic for certain people. Safety considerations become particularly important for individuals with autoimmune disorders, those taking specific medications, pregnant or nursing women, and people with certain allergies or digestive conditions that may be exacerbated by functional mushroom compounds. Informed consumption of mushroom coffee demands understanding both the potential benefits and the legitimate contraindications that apply to various health situations and demographic groups.
What Is Mushroom Coffee and Why the Hype?
Mushroom coffee blends regular coffee beans with extracts from medicinal mushrooms, such as chaga, reishi, and lion’s mane. The idea is you get the caffeine boost from coffee, plus potential health benefits from the mushrooms.
Most mushroom coffee contains less caffeine than regular coffee, usually about half the amount.
These mushroom coffee products come as ground coffee, instant powder, or specialty coffee blends you can brew at home. The taste is quite similar to regular coffee, although some people may notice an earthy flavor from the mushroom powder.
The hype surrounding mushroom coffee centers on claims of immune support, improved focus, and reduced stress. However, here’s the thing: not everyone should experiment with these compounds.
People Who Should Avoid Mushroom Coffee
1. Those with Kidney Problems
If you have kidney disease or kidney stones, consuming mushroom coffee may exacerbate these conditions. Chaga mushroom contains high levels of oxalates, which can worsen kidney issues and increase your risk of kidney stones. Your kidneys already work harder when they’re damaged, and adding oxalate-rich mushroom products can exacerbate the problem.
People with chronic kidney disease should definitely avoid mushroom coffee unless their doctor specifically says it’s okay.
2. People Taking Blood-Thinning Medications
Reishi mushrooms can affect blood clotting, which means they might interact with blood-thinning medications like warfarin or aspirin. If you’re on any medication that affects blood clotting, mushroom coffee could increase your risk of bleeding or change how well your medication works.
This isn’t just about prescription drugs; even over-the-counter pain relievers can interact with mushroom compounds.
3. Anyone with Autoimmune Conditions
Medicinal mushrooms can stimulate your immune system, which sounds good in theory. But if you have an autoimmune condition like rheumatoid arthritis, lupus, or multiple sclerosis, this immune stimulation could make your symptoms worse.
The mushrooms used in mushroom coffee may help a healthy immune system, but they can cause problems when your immune system is already overactive.
4. Pregnant and Breastfeeding Women
There’s not enough research on the effects of mushroom coffee during pregnancy and breastfeeding. Since mushroom coffee contains both caffeine and bioactive compounds from mushrooms, it’s better to stick with regular coffee in moderation or avoid caffeine altogether.
The amount of mushroom extract used in mushroom coffee varies between brands, making it challenging to determine a safe dosage during pregnancy. So the best bet is just to stay away from it during that period.
5. People with Severe Caffeine Sensitivity
Although mushroom coffee contains less caffeine than regular coffee, it still contains caffeine. If you’re extremely sensitive to caffeine or have been advised to avoid it altogether, mushroom coffee may not be a suitable option.
Some people think mushroom coffee is caffeine-free, but that’s not true unless you buy specifically decaffeinated versions.
Potential Side Effects of Mushroom Coffee
Even if you don’t fall into the high-risk categories, mushroom coffee can still cause side effects:
1. Digestive Issues: Some people get stomach upset, nausea, or diarrhea from mushroom extracts. Starting with small amounts can help you figure out how your body reacts.
2. Allergic Reactions: If you’re allergic to mushrooms, mushroom coffee is off-limits. But even people without known mushroom allergies can develop reactions to concentrated mushroom extracts.
3. Sleep Problems: The caffeine in mushroom coffee can still disrupt your sleep, especially if you consume it later in the day.
4. Interactions with Supplements: Mushroom coffee may interact with other supplements you’re taking, especially those that affect your immune system or blood sugar levels.
When to Talk to Your Doctor First
You should check with your healthcare provider before incorporating mushroom coffee into your routine if you:
- Take any prescription medications
- Have a chronic health condition
- When recovering from surgery
- Take supplements regularly
- Have a history of kidney problems
- Have an autoimmune disorder
Your doctor, who is familiar with your medical history, can advise you on whether mushroom coffee is safe for you, taking into account your specific situation. Don’t assume it’s harmless just because it’s marketed as a health product.
Safer Alternatives to Consider
If mushroom coffee isn’t right for you, there are other ways to upgrade your coffee routine:
Quality Specialty Coffee: High-quality coffee beans can provide an exceptional flavor experience without artificial additives. Single-origin coffees and expertly roasted blends can be just as satisfying.
Herbal Coffee Substitutes: Chicory coffee, dandelion root coffee, and other herbal alternatives give you a coffee-like experience without caffeine or mushroom extracts.
Traditional Coffee with Adaptogens: If you want adaptogenic benefits, consider adding separate, well-researched supplements to your routine rather than getting them through coffee.
Decaf Options: Enjoy the ritual and flavor of good decaffeinated coffee without caffeine concerns.
If you’re specifically interested in the benefits of mushrooms, mushroom edibles designed for precise dosing may be a better option than coffee blends, which often vary in their mushroom content.

Make Safe and Informed Mushroom Coffee Decisions
The responsibility for safe mushroom coffee consumption ultimately rests with individual consumers who must evaluate their personal health circumstances against the known contraindications and potential risks associated with functional mushroom products. Healthcare providers play a crucial role in this decision-making process, especially for people with existing medical conditions, those taking prescription medications, or individuals in vulnerable populations who may face increased risks from bioactive compounds. The growing popularity of mushroom coffee makes it essential for consumers to approach these products with the same caution they would apply to any supplement that could affect their health or interact with their current treatments.
Education about mushroom coffee safety empowers consumers to make informed decisions that balance potential wellness benefits with realistic assessment of personal risk factors and health considerations. The most responsible approach involves consulting healthcare providers before incorporating mushroom coffee into daily routines, especially for individuals who fall into higher-risk categories or have questions about potential interactions with their current health management strategies. This proactive approach ensures that the pursuit of wellness benefits does not inadvertently compromise existing health conditions or interfere with important medical treatments.
Your decision about mushroom coffee consumption should be based on comprehensive understanding of both your individual health profile and the specific contraindications that apply to your circumstances rather than following popular trends or marketing claims alone. The safest approach involves honest assessment of your health status, open communication with healthcare providers, and careful consideration of whether the potential benefits justify any risks associated with your particular situation. When you prioritize safety alongside wellness goals, you can make informed choices about mushroom coffee that support your health journey without compromising your well-being or existing medical care.
