Goji berries contain unique compounds known as Lycium barbarum polysaccharides, most often referred to as polysaccharides. Research has shown that these compounds enhance the body's ability to resist disease. Goji's polysaccharides have a chemical structure similar to substances found in echinacea and maitake mushrooms, herbs known for their ability to support a healthy immune system.
The berries are also a rich source of vitamin C and zinc, both of which are known to protect against disease and aid in recovery. Research at Case Western Reserve University has shown that zinc can shorten the length and severity of a cold. Zinc deficiencies are more likely to occur as we age and produce less stomach acid.

    *growth and repair of all human tissues

    *formation of collagen in skin, scar tissue, tendons, ligaments and blood vessels

    *wound healing

    *healthy cartilage, bones and teeth

Zinc, also an antioxidant, is needed for:
