The two are actually quite different but equally beneficial..
Cellfoods provides vitamins, minerals, amino acids & dissolved oxygen. It's intended to replace the lost minerals in your body that are required to fight off infection. #
35% Food Hydrogen Peroxide provides your body with an oxygen rich environment which would allow good bacteria to survive & thrive. Harmful bacteria are diminished because they prefer to survive in an anaerobic environment (poorly oxygenated).
Either is good, though personally if i had to choose, I would go with Cellfoods. It has a higher satisfaction rate.
