Short answer

We found no direct interaction between CoQ10 and Cordyceps in the sources below, but they share a caution.

Both have a note about blood thinners such as warfarin (see each one below).

Both have a note about diabetes medicines (see each one below).

CoQ10

What it is: A compound the body makes, found at high levels in the heart, liver and kidneys.

What the research says: Studies on heart disease are inconclusive. Overall, it doesn't seem to relieve muscle pain from statins, and it probably doesn't lower blood pressure meaningfully.

Cautions

• No serious side effects reported; it can cause mild insomnia or stomach upset.

Medicines to check

• Warfarin (blood thinner) and insulin
• Some cancer treatments: check with your care team

Cordyceps

What it is: A fungus that grows on moth caterpillars, used in traditional Chinese medicine for energy and immunity.

What the research says: Some studies looked at kidney function in transplant and diabetes patients, but reviews question the quality of the evidence. Most research is in the lab.

Cautions

• No major side effects have been reported.

Medicines to check

• Insulin and other blood-sugar-lowering medicines: cordyceps may lower blood sugar too
• Blood thinners such as warfarin: it may raise bleeding risk
