Arginine Supplement Shows Cancer, Virus Promise
Tap title to read story
A recent study from Rockefeller University suggests that the amino acid arginine could strengthen the immune system’s ability to fight cancer and viral infections. Researchers found that low arginine levels hinder the production of MHC‑1, a protein essential for immune recognition of abnormal cells. In mouse experiments, increasing dietary arginine reduced colon cancer tumor formation and lessened the severity of influenza and SARS‑CoV‑2 infections. Remarkably, administering arginine after influenza infection also improved outcomes. The findings, published in the journal Cell, indicate that an inexpensive, readily available supplement might eventually complement cancer therapies and antiviral strategies, though human trials are still needed.
