1. AFA Extract® contains a polysaccharide fraction that was shown to stimulate the migration of Natural Killer (Killer (NK) cells out of the blood into tissues. The same polysaccharide fraction was also shown to strongly stimulate the activation of NK cells. NK cells play the very important role in the body of identifying aberrant or defective cells and eliminating them. NK cells are especially known for their ability to detect and destroy virally infected cells and cells und
ergoing uncontrolled cellular division.
2. The same polysaccharide fraction was also shown to stimulate macrophage activity. Macrophages constitute the front line of the immune system. They first detect an infection or the presence of bacteria or virally infected cells, and they then call for a full immune response. They call for backup!

3. The immune system is the main producer of free radicals and inflammation in the body. 
Therefore, the fact of “stimulating” the immune system carries the possibility of increasing oxidative stress and inflammation in the body. The effect of AFA consumption of the ability of neutrophils to produce free radicals was tested. To our surprise, consumption of AFA actually slightly reduced the ability neutrophils to produced free radicals.
4. AFA Extract® contains a significant concentration of phycocyanin, the blue pigment in AFA. Phycocyanin has strong anti-inflammatory properties and therefore can assist the immune system.
5. AFA Extract® also contains chlorophyll, which is well known for its blood purifying properties.
AFA Extract® support several aspects of immune function while reducing the production of free radicals. As such, Stem Cell Nutrition is not so much an “immune stimulant” as an “immune balancer"
