For more information visit http://www.lifespanglobal.com Why ImmuniPro™? The ImmuniPro™ formula can only be available in a Pure Vegan Capsule. LifeSpan calls this capsule, "Controlled Release Encapsulation." This formula has been synergistically blended following a precise, time sensitive process. From the Encapsulation to the ingredients, ImmuniPro™ is designed to release its ingredients at a slow but steady pace allowing maximum absorption into the bloodstream while having the advantage of being taken at less frequent intervals than immediate release. ImmuniPro's™ formula, of "Controlled Release Encapsulation," enables it to be over 95% absorbed in the human Gut. Our proprietary ImmuniPro™ formula, contains very HIGH POTENTENCY ingredients for the human Gut. And where potencies, of these higher concentrations are concerned, purposely controlled absorption under the proper Gut Ph, is highly preferable to the more rapid immediate release and absorption critical to the success of the PhytAlive!™ formula. This is because our digestive tract has limits as to how fast and how much of a given nutrient, such as those contained in ImmuniPro™, can be absorbed in a per unit of time. If you overwhelm these absorption pathways with ImmuniPro's™ extra high potency, you waste beneficial nutrients. When it comes to the essential nutrients in ImmuniPro™... Slower is Better! For other types of nutritional supplements, such as PhytAlive!™, a more rapid uptake provides a significant beneficial difference, and is the primary cause of PhytAlive's!™ market dominance in these delivery systems. http://www.lifespanglobal.com
