Immune System Science The chart on the right hand side shows the average North American population has below average NK cell activity (20 - 50 Lytic Units (LU) vs. healthy 150 - 225 LU). The study was conducted over 13 months with 107 patients, averaging 53 years, 50% of which had cancer, 30% chronic fatigue, 20% other including lupus, allergies, fibromyalgia, chronic infections among others. The Result: average monthly increase per patient: 28.25 LU     Biomune OSF Plus and Natural Killer (NK) Cells  Recognize Respond Remember   The immune system is composed of millions of cells, numerous chemicals, glands and organs which all work together via a complex communication system. Natural killer cells, known as antibodies, and Natural Killer cell activity is a biological marker for disease, an important indicator for declining or improving health. Natural Killer Cells' job is to scavenge (recognize), destroy (respond) and memorize infectious cells in the body. They have the ability to destroy infectious cells stone dead, on contact. Biomune strengthens the Natural Killer Cells. Biomune OSF Plus reestablishes critical communication pathways in the immune system (IS) which increases its surveillance function, increasing its Natural Killer cell activity and vigilance.
