The NHI devise Packages consisting of multiple products that are very effective when used in concert to improve a specific disease condition. All those packages contain many more ingredients including ones that you will rarely be offered all in one comprehensive product - by other manufacturers. Our packages are carefully balanced to give you an optimum solution for a particular disease condition. It is important to understand that most nutrients work best when combined with others. This is called synergy. We never compromise on quality, dosage or effectiveness. We do not use anything that doesn't work and we do not miss out anything that does work. Typically, if you our analyse our list of ingredients, as part of a package, they will cost less than half and often even less than a third of what they would cost by buying the same ingredients in other formulations elsewhere.
