Heme Iron Raises, Zinc Lowers Colon Cancer Risk - The March 3 2004 issue of the Journal of the National Cancer Institute published the results of a study which found a positive association between the possible prooxidant heme iron and colon cancer, and a negative association between the antioxidant zinc and the disease. Heme iron, from liver fraction, is the most easily absorbed and least constipating form of iron. Iron can create free radicals and it is best to supplement iron in food form with vitamin C, as in the Ultimate Iron formula. Iron protein succinylate (Iron Protein Plus) may be the most effective oral treatment for iron deficiency anemia. Studies on the effectiveness of iron protein succinylate showed the following results after 60 days: (1) 23% increase in percentage of red blood cells (hematocrit); (2) 30% increase in oxygen carrying capacity of blood (hemoglobin); (3) 6% increase in total number of red blood cells.

Liquid Vitamin A - Vitamin A (retinol) is a yellow, fat-soluble solid terpene alcohol obtained from some carotenoids by conversion in the liver, its storage organ. While carotenoids are widely distributed in such foods as green and yellow vegetables, retinol is not found in any vegetable sources, but is concentrated in egg yolks and the livers of many animals. Vitamin A, either from animal sources or synthesized in our own liver, is essential for growth and reproduction, maintaining healthy vision, and supporting protein synthesis and cell differentiation. Vitamin A and its analogs have also shown the ability to help maintain proper DNA function. Optizinc - Zinc is a mineral essential for formation of superoxide dismutase, one of the body’s most important free radical scavengers and one that cannot be directly supplemented. Zinc also promotes wound healing, immune function, taste sensitivity, protein synthesis, insulin production, and reproduction including organ development and sperm motility.
