*It is important to note that the peer-review process ensures that the Scientists, PhDs, and MDs facilitating this research have no bias toward specific brands, variations, or the companies involved. Their sole purpose is to analyze the material in question and to discover how these products impact the immune system, rather than what the companies that manufacture them claim they are doing.
