Glandular therapy has been around for many years. The idea of gladular therapy is that the use of animal tissues may enhance the proper functioning of corresponding human tissues. The majority of glandulars are derived from bovnie sources although some may originate from porcine sources. Some examples of tissues that are thought to benefit from such supplementation include, adrenal, thyroid, thymus, pituitary, liver, pancreas, spleen, kidney, etc...There are many that believe extra supplementation of these tissues by similar properties will improve the function of the gland. Each gland is crucial to the body for different reasons. WebVitamins has a selection of glandular products to fit individual needs.
