What is Cordyceps sinensis extract?

Cordyceps sinensis extract is a concentrated supplement made from the traditional medicinal fungus known as caterpillar fungus. It contains bioactives such as cordycepin and polysaccharides.

What are the main benefits of Cordyceps sinensis extract?

It is commonly used for immune support, vitality, and exercise performance, with additional interest in antioxidant, metabolic, and cardiovascular support. Human evidence exists for some uses but remains limited overall.

What is a typical dosage for Cordyceps sinensis extract?

Common supplemental ranges are about 1000–3000 mg per day, depending on the product and extract strength. Follow the label directions and consider starting at the lower end to assess tolerance.

Does Cordyceps sinensis extract improve exercise performance?

Some small human studies and traditional use suggest it may modestly support aerobic performance and reduce fatigue. Effects can vary by individual and by the specific extract used.

Is Cordyceps sinensis extract safe, and who should avoid it?

It is generally well tolerated for many people, but side effects like digestive upset can occur. People who are pregnant or breastfeeding, have autoimmune conditions, take immunosuppressants, or are undergoing cancer treatment should consult a clinician before use.

Safety & Information

Important safety information & known risks

For educational purposes only • not medical advice

Generally well-tolerated in most people; notable risks exist for immune and bleeding-related conditions.

warning notices

Mild gastrointestinal symptoms (nausea, diarrhea, dry mouth) are the most common side effects.
May increase risk of bleeding and immune activation in sensitive populations.
Safety during pregnancy or breastfeeding is unproven; avoid use.
Avoid use if pregnant or breastfeeding due to insufficient safety data.
Discontinue use at least two weeks before surgery; may increase bleeding risk.
Avoid use if you have a bleeding disorder, as cordyceps may increase bleeding risk.
Use caution or avoid if you have an autoimmune condition, as cordyceps may stimulate the immune system.
May interact with immunosuppressant and anticoagulant medications; consult with a healthcare professional if taking these.

Known interactions with medications

Anticoagulants
Antiplatelet drugs
Immunosuppressants

Contraindications / special precautions

Pregnancy
Breastfeeding
