Chlorella
+
Glutamine

Short answer

We found no documented interaction between Chlorella 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.

Chlorella

What it is: A green freshwater alga sold as a supplement.

What the research says: A review of 10 trials found modest drops in total and LDL cholesterol. Only 2 of those trials checked what the supplements actually contained.

Cautions

  • That review didn't assess safety, and we didn't find a reliable safety review.

Medicines to check

  • Talk to your clinician if you take any medicine

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. Glutamine is already lab-dosed and delivered daily in our Gut Pack — one less bottle to manage.
