The 2010 Study titled “Silver Bullet or Hot Air,” done by Dr. Vetvicka’s team showed the effectiveness of various immune system products on factors such as Neutrophil Phagocytosis, the Oxide Production of Cellular Nitrites, & IL-2 Secretion. This study featured almost one dozen different products that vary in their primary ingredient: including but not limited to mushrooms, yeast, and barley. One of the featured supplements was the Immune Health Basics’ WGP® (i.e., Whole Glucan Particle) material.
This 2010 study done by Dr. V and his team was conducted without special interest; the goal was to identify, in the most objective fashion, the best product for the human immune system. These results are conclusive and have been corroborated by additional studies within the past decade.
