Hi, I just went to that link and found, not surprisingly, that it's a commercial site selling its own products. Of course there's nothing the matter with boosting the immune system, but I need to point out the following text, taken directly from that site.
"The information has not been evaluated by the FDA or by 4Life Research. We do not claim that 4Life products directly prevent, or cure any disease. We do not suggest that anyone should replace traditional medical treatment with our products... We encourage you to use common sense in your expectations in consuming any nutritional product... Seek advice from your health care professional regarding the applicability of any information, opinion or recommendation for diagnosis or treatment of any symptoms or medical condition. Statements about products and health conditions have not been evaluated by the U.S. Food & Drug Administration.

It's one thing for the FDA not to evaluate something, but a health site that doesn't even evaluate its own products? Always read the fine print with ANYthing, especially regarding your health.
