Simply put, Syntra-Shield's active ingredient (a patented yeast-derived gluco polysaccharide) activates a large population of the body's own immune cells to enhance natural defences against foreign challenges. Once swallowed, It is taken up into the body through the Peyer's Patches, specialised regions in the small intestines. There are immune cells called macrophages that engulf the active ingredient in Syntra-Shield and degrade it into smaller fragments that bind to neutrophils, the most abundant immune cell in the body. Primed with this unique ingredient, neutrophils more effectively circulate throughout the body and kill foreign challenges. Published Reports: Nutrition Industry Executive "In a double-blind, placebo-controlled study with 40 subjects 18-65 years old, the active ingredient in Syntra-Shield (a patented yeast-derived gluco polysaccharide) reduced the incidence of fever and eliminated the need to miss work or school due to cold-like symptoms." Results were presented at Experimental Biology 2008. Natural Products Insider "Subjects taking the active ingredient in Syntra-Shield reported a 42% increase in vigour and 38% reduction in fatigue, and significantly fewer subjects on active treatment had any type of upper respiratory infection symptoms." Nutraceutical Business & Technology " The active ingredient in Syntra-Shield activates a natural immune mechanism to increase the ability of macrophages to phagocytose or engulf and destroy foreign challenges" Nutraceuticals World "Syntra-Shield's active ingredient primes key immune cells, including macrophages and neutrophils (types of white blood cells), to quickly identify and kill foreign challenges."
