Glutamine

Short answer

We found no documented interaction between Cordyceps and Glutamine in the sources below. That isn't proof the combination is right for you: check each one's cautions, and ask your pharmacist if you take medication.

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

Glutamine

What it is: An amino acid the body makes and uses for energy and to build protein.

What the research says: It has little or no benefit for strength or recovery. It's studied mainly in cancer care and after surgery.

Cautions

  • Studies report no side effects at up to 45 g a day for several weeks; reported side effects elsewhere include headache and nausea.
  • Don't confuse it with glutamate, which is a different substance.

Stop Guessing Your Dosages.

Balancing dosages across multiple different bottles is risky, inefficient, and expensive. Cordyceps is already lab-dosed in our Stress Pack, and Glutamine is in our Gut Pack — either way, that’s one less bottle to manage.
