This Simple Supplement Could Help Boost Immune Function
- Arginine does more than help build proteins — your cells also need this amino acid to produce immune-alert proteins that help T cells recognize infected or abnormal cells
- When arginine became scarce, the cellular machinery responsible for building these immune-alert proteins stalled, leaving fewer warning signals available to help the immune system detect threats
- In mice, increasing dietary arginine reduced colon tumor formation and improved outcomes in influenza and SARS-CoV-2 infections, benefits that disappeared when researchers disabled the immune pathway arginine supports, confirming the effect wasn't coincidental
- Whole foods are the preferred starting point for maintaining healthy arginine intake, with grass fed beef, lamb and watermelon providing options without relying automatically on supplements
- Adequate protein, sufficient carbohydrates and lower linoleic acid intake support the broader cellular environment your immune system needs to produce energy, build proteins and respond effectively to threats
