Overall, cordyceps mushrooms’ medicinal and adaptogenic properties can benefit your physical and mental health.

Side Effects Of Cordyceps Mushrooms
Generally speaking, all functional mushrooms are well-tolerated when consumed as food and in supplement form. Cordyceps mushrooms in particular are safe when taken in doses up to six grams. (Source)
Cordyceps mushrooms are also low in oxalates, an antinutrient that triggers inflammation and decreases the body’s nutrient absorption.
That being said, cordyceps mushrooms are not for everyone. They can cause allergic reactions and interfere with certain medications.
Here are four potential cordyceps mushroom side effects.
1. It May Cause Hypoglycemia
Cordyceps mushrooms have hypoglycemic properties, which means it has the ability to lower your blood sugar or glucose levels.
For example, one study showed that cordyceps mushrooms lowered blood sugar levels in rats with diabetes. (Source)
While this can be great for some people, cordyceps may drop blood sugar to dangerously low levels when taking blood pressure medications.
Due to this, it is best to check in with a health professional before taking cordyceps mushrooms if you take blood pressure medications.
2. It May Cause GI Symptoms
Cordyceps mushrooms may cause gastrointestinal symptoms in some people.
GI symptoms include digestive discomfort, bloating, constipation, diarrhea, and vomiting.
However, these symptoms generally only occur when taking high doses.
3. It May Interfere With Blood Clotting
Some research shows that cordyceps mushrooms may hinder the body’s ability to clot blood.
While this antiplatelet effect is beneficial in some circumstances, it can decrease the effectiveness of blood clotting medications.
Due to this, it is best to check in with a health professional before trying cordyceps mushrooms if you take blood thinners.
4. It May Exacerbate Autoimmune Conditions
One of the main benefits of cordyceps mushrooms is their ability to support immune function.
However, this support can be counterproductive for people with certain autoimmune conditions. This is because autoimmune disorders cause the immune system to go into overdrive.
Therefore, stimulating the immune system with cordyceps mushrooms may worsen certain conditions.
Who Should Not Take Cordyceps Mushrooms for Risk of Side Effects?
Cordyceps mushrooms are generally safe to consume and have few side effects.
However, you should consult a healthcare professional before trying a cordyceps mushroom supplement if you:
- Take blood pressure medication or blood thinners
- Are you allergic to mushrooms
- Have an autoimmune disorder
You should also consult your doctor before trying cordyceps mushrooms if you are pregnant or breastfeeding. This is because the effects of cordyceps on pregnancy and breastfeeding are relatively unexplored.
The best way to avoid side effects is by taking cordyceps mushrooms in a normal dose.
If you’re wondering how much cordyceps per day, health experts recommend taking no more than 1400 mg daily.
