Scientific Studies On 198 Natural Products


Recently we reported the initial results of a groundbreaking independent study using Transfer Factor and Transfer Factor Plus . Both yielded unprecedented results in a study done by the Institute of Longevity Medicine in California, a laboratory recognized for its research and expertise in measuring the ability of ingredients to significantly boost the immune system.

Transfer Factor and Transfer Factor Plus were tested for their ability to increase Natural Killer Cell (NK) activity. The researchers used peripheral blood mononuclear cells (PBMC) isolated from human volunteers. Test results showed that Transfer Factor boosted NK cell activity 103% above normal immune response without supplementation, more than two times higher than the next highest product. The study also showed that Transfer Factor Plus increased the NK cell activity 248% above normal immune response without supplementation, or about five times higher than any of the other previously tested products.

Natural Killer Cells are an important part of our body's immune system. They seek and destroy harmful cells through direct contact. Natural Killer Cells are especially important in strengthening and supporting the immune system.

David Lisonbee, CEO of 4Life Research, in response to this research said, "These recent findings support and substantiate the reports from thousands of distributors who use Transfer Factor and Transfer Factor Plus. The study also supports many other clinical experiences and studies we are familiar with. We are very pleased with the study results, they come as no surprise to us."
