Headaches and Dizziness
Some users report experiencing headaches and dizziness after consuming Reishi mushrooms. These symptoms can range from mild to moderate but are usually temporary.
Statistics and Studies
A study involving 100 participants who consumed Reishi mushroom extracts revealed that 20% of participants experienced mild gastrointestinal distress. Another 10% reported headaches and dizziness. Though these numbers are not significantly high, they are still noteworthy for individuals who may be sensitive or prone to side effects.
Rare but Serious Side Effects
Though Reishi mushrooms are generally considered safe, some rare but serious side effects have been documented.
Liver Toxicity
Liver toxicity is one of the most severe potential side effects of Reishi mushrooms. There have been isolated cases where individuals experienced liver damage after consuming high doses for extended periods. Symptoms of liver toxicity can include:
- Jaundice: Yellowing of the skin and eyes.
- Fatigue: Extreme tiredness or lethargy.

Blood Pressure Changes
Reishi mushrooms can affect blood pressure. Although some studies suggest they may help reduce high blood pressure, they can also lower it to dangerous levels in people already on blood pressure medications.
Medical Studies and Documentation
In a study published in “Liver International,” researchers documented a case where a 68-year-old man developed acute hepatitis after taking Reishi mushroom supplements for two months. Another notable article in the “Journal of Clinical and Experimental Hepatology” highlights a 52-year-old woman who experienced severe liver damage attributed to high doses of Reishi mushrooms. These instances underscore the importance of being cautious with dosage and duration of use.
Factors Influencing Side Effects
Understanding the factors that can influence the side effects of Reishi mushrooms will help you make more informed decisions.
Dosage and Duration
The dosage and duration of Reishi mushroom consumption are crucial factors. Generally, side effects are more likely to occur at higher doses or with prolonged use.
- Low Dosage: Side effects are generally minimal or non-existent.
- High Dosage: Increased risk of side effects such as digestive issues or liver toxicity.
- Prolonged Use: Extended consumption increases the likelihood of cumulative side effects.
Individual Health Conditions
Your individual health conditions can significantly influence how your body reacts to Reishi mushrooms.
- Pre-existing Liver Issues: More likely to experience liver toxicity.
- Allergies: Increased risk of allergic reactions.
- Blood Pressure Issues: Greater propensity for blood pressure changes.
Medication Interactions
Reishi mushrooms can interact with several types of medications. You should be aware of these potential interactions:
- Blood Thinners: Increased risk of bleeding.
- Immunosuppressants: Potentially diminished effectiveness.
- Chemotherapy Drugs: Possible enhancement or reduction of efficacy.
Research Findings
A clinical trial indicated that lower doses, around 1.5 to 9 grams per day, generally led to fewer side effects. However, it’s essential to consider individual conditions and potential medication interactions to ensure safe use.
By keeping these factors in mind, you can better navigate the complexities of using Reishi mushrooms for health benefits while minimizing the risk of adverse effects.
Interactions with Medications
Reishi mushrooms can interact with various medications, posing risks that you need to be aware of. Such interactions can either enhance or diminish the efficacy of the drugs you’re taking. Understanding these interactions can help you avoid potential complications.
Blood Thinners
Reishi mushrooms have anticoagulant properties, meaning they can thin the blood. If you are on blood-thinning medications like warfarin or aspirin, consuming Reishi mushrooms can increase the risk of bleeding. This makes the combination particularly risky and demands careful management.
Immunosuppressants
Individuals taking immunosuppressant medications should exercise caution. Reishi mushrooms can stimulate the immune system, potentially reducing the effectiveness of immunosuppression. This can be problematic, particularly for those who have undergone organ transplants or are managing autoimmune diseases.
Chemotherapy Drugs
Reishi mushrooms can interact with chemotherapy drugs, which can either amplify or reduce their effectiveness. This interaction isn’t fully understood yet, but it underscores the need to tread carefully if you are undergoing cancer treatment.
Laboratory Tests
Reishi mushrooms can interfere with certain laboratory tests. For instance, they can affect CA72-4 levels, an antigen used in some cancer diagnostics. The implications of such interferences can lead to misdiagnoses and inappropriate treatment plans.
Practical Considerations
To mitigate these risks, keep the following tips in mind:
- Monitor Symptoms: Be vigilant about any unusual symptoms when you start taking Reishi mushrooms.
- Start Slow: Begin with a lower dose and gradually increase to allow your body to adjust.
- Consult Healthcare Providers: Always involve your healthcare team when adding new supplements to your regimen.
Groups at Higher Risk
Certain groups of people should be especially cautious when considering the use of Reishi mushrooms. These include pregnant and breastfeeding women, individuals with autoimmune diseases, and those preparing for surgery.
Pregnant and Breastfeeding Women
There is insufficient research on the safety of Reishi mushrooms for pregnant and breastfeeding women. Due to the potential for unknown risks, it’s generally advised to avoid these supplements during these sensitive periods.
Individuals with Autoimmune Diseases
Reishi mushrooms can stimulate the immune system, which can worsen conditions like rheumatoid arthritis or lupus. If you have an autoimmune disorder, you should weigh the benefits and risks carefully before incorporating Reishi mushrooms into your routine.
People Undergoing Surgery
Because Reishi mushrooms can affect blood clotting, they may increase bleeding risks during surgery. It is advisable to discontinue their use at least two weeks before any scheduled surgical procedures to minimize this risk.
Guidelines for These Groups
- Avoid Use: Pregnant and breastfeeding women should avoid Reishi mushrooms.
- Consult Healthcare Providers: If you have an autoimmune disease or are scheduled for surgery, consult your healthcare team.
- Monitor Work with Healthcare Providers: Continuous monitoring can help manage any adverse effects effectively.

Beginning with a lower dose allows your body to acclimate gradually. Most supplements specify a recommended starting dose, and adhering to this can significantly reduce the risk of adverse effects.
Monitor for Symptoms
Keep an eye on any new or unusual symptoms that arise after starting Reishi mushroom supplements. Minor issues like headaches or digestive discomfort can be early indicators that adjustments are needed.
Consult Healthcare Providers
Ongoing consultation with your healthcare team can provide valuable insights and personalized advice. They can help you tailor the dosage and watch for potential interactions with existing medications.
