"Together's vegan, plant based broad spectrum Zinc is made from organic Guava leaves and contains all the naturally occurring co-factors and co-nutrients found in the Guava leaf. Together's zinc is minimally processed and raw to keep all these important nutrients intact ensuring co-nutrients such as beta-sitosterol, polyphenols, flavonoids, ursolic acid, essential oils and tannins are available to increase the activity of the zinc. These natural components of the whole leaf ensure that the Zinc is easily recognised, metabolised, and absorbed by the body. It is organic certified and completely free of chemicals and synthetics, just as nature intended. Zinc is necessary for the activity of over 300 enzymes that aid in metabolism, digestion, nerve function and many other processes. Together's all-natural form is exactly what your body needs. No artificial additives or processing aids."
