Colds, flus and other illnesses can cause dangerous respiratory infections. These recent studies suggest nutrients that may be helpful in fortifying the immune system.

  1. The amino acids Arginine and L-Citrulline (both increase arginine concentrations) both appear to support respiratory health in the face of viral infections. See this recent Lancet article
  2. Vitamin D (helpful for all respiratory infections) – See this study
  3. Zinc – See this study
  4. Xylitol nasal spray – See this study
  5. Fisetin (a large dose once a month) (kills senescent cells that make us vulnerable to certain kinds of viral infections) – See this study
  6. Elderberry –– supports respiratory health, and as a bonus, activates the sirtuin 6 gene. See this article
