An expert in the field of understanding how toxins affect our bodies, Dr. Arthur Furst developed GNLD Betaguard to answer his personal and professional concerns regarding the escalation of toxic assaults to our environment. The result of Dr. Furst´s expertise and ongoing scientific research is Betaguard, a blend of antioxidants and detoxifying nutrients which work together to help the body neutralize and metabolize toxic materials. Many pollutants do their damage by increasing oxidative attacks on the body´s cells. Each two-tablets serving of Betaguard provides the beta-carotene and other carotenoids of two carrots. These antioxidant nutrients have been shown to play active roles in protecting delicate body tissues. In addition, Betaguard contains vitamin C and vitamin E from natural plant sources to provide antioxidant protection for both the watery and lipid portions of cells, respectively.
