Phyto-Shield by Douglas Labs is a natural immune system support supplement that contains significant amounts of several key nutrients including echinacea and zinc, specially formulated to aid in immune support.
Native Americans traditionally used echinacea for a variety of disorders, primarily infections and other conditions where enhancement of the immune system was needed. Echinaceas therapeutic efficacy was recognized by Western medical science in the late 19th century. Today, echinacea is best known as a non-specific, immuno-supporting botanical.
Zinc is an essential trace element required for the activity of over 300 enzymes and is involved in most major metabolic pathways. Zinc participates not only in catalytic processes, but also in the structure and stability of some regulatory proteins.
Eleutherococcus senticosus may support stimulating the production of interferon, thus enhancing the functioning of macrophages, natural killer cells, and cytotoxic T cells.
Nutrients such as garlic and Korean ginseng can also play important roles in the support of healthy immune function.
