There is, however, a caveat to the use of chlorella. See my last chlorella video Treating Hepatitis C with Chlorella (http://nutritionfacts.org/video/treating-hepatitis-c-with-chlorella/) to make up your own mind if the benefits outweigh the risks.

Here’s the nutritional yeast study I mentioned: Preserving Immune Function in Athletes With Nutritional Yeast (http://nutritionfacts.org/video/preserving-immune-function-in-athletes-with-nutritional-yeast/)

Here’s some other ways to decrease your risk of upper respiratory tract infections:
