I do have some additional information to share about Shaklee’s natural interferon product, including the links below and the video at this link: http://antiagingbydesign.com/interferon-powers-your-immune-system

From Shaklee:

Nutriferon was Created by the Discoverer of Interferon
World-renowned immunologist Dr. Yasuhiko Kojima first discovered interferon in 1954, while he was conducting research at Tokyo University. After 40 years of painstaking research, testing hundreds of natural compounds, he developed a unique blend of four powerful plant extracts that boosts the body’s natural production of interferon.

Naturally Increases Levels of Interferon
Scientists and medical communities have identified interferon as critical to healthy immune function. NutriFeron is the only dietary supplement in the U.S. created by the discoverer of interferon that naturally increases the production of interferon in the body.

Proven by Four Human Clinical Studies
This potent-yet-safe phytonutrient blend provides immune support right at the cellular level. Studies have shown the extraordinary health and immune protection benefits of NutriFeron’s proprietary blend of four plant extracts.

Exclusive Patented Formula
NutriFeron is available only through Shaklee. This unique patented formula is a Shaklee exclusive. A powerfully effective supplement, it has exceeded a stringent set of scientific tests for safety, purity, potency, and performance.
