A, C and E, beta-carotene, the trace elements selenium, manganese, potassium, zinc molybdenum and iron and the sulfur containing amino acids, Cysteine and Methionine . The B-complex vitamins are important for cellular maintenance and potentiate the action of antioxidants. Vitamin C and the bioflavonoids increase capillary resistance to damage by free radicals. Membrane stabilizers include PABA, inositol and choline . Calcium, magnesium and potassium are vital for cell stabilization and proper functioning.
Vitamin D aids in the absorption of calcium .
The human body lacks an effective enzymatic defense against the very destructive free radical precursor, excited state singlet oxygen. Beta-carotene deactivates atoms of singlet oxygen and can therefore prevent damage to DNA and other cellular constituents. Molybdenum is known to be present in several enzymes and it is also necessary for iron utilization. Many anti-oxidant nutrients vital to free radical protection also serve as natural chelators. Vitamins C and E and the amino acids, cysteine and methionine , help rid the body of toxic metals such as lead and abnormally located iron and copper, all free radical catalysts.
