Nutritional Ranking of Vitamins and Minerals
A recent independent (non-commissioned) Canadian study examined and evaluated hundreds of American and Canadian nutritional products. The criteria for evaluation and subsequent ranking included:
- Completeness of the full spectrum of nutrients
- Potency levels
- Antioxidant levels of vitamin E, C and beta-carotene
- Components for the Glutathione Peroxidase Pathway
- Insulin Resistance Defense System components (biotin, pantothenic acid, chromium, magnesium and vitamin E)
- Cardiac Health properties (coenzyme Q10, vitamin E and folic acid)
- Homocysteine Reduction properties (vitamin B6, B12 and folic acid)
- Bioactivity of Vitamin E
- Bioflavonoid mixture
- Bioavailability (forms of minerals)
- Lipotropic factors (choline and inositol)
- Potential Toxicities (vitamin A and iron)
197 children's nutritional products were initially reviewed in this study. Only 115 of these products provided sufficient nutritional detail to be considered for further evaluation. The final criteria identified 100 children's products which were subjected to complete graphical analysis. This study also reviewed over 400 adult nutritional products. Only 254 of these qualified for complete graphical analysis. The results of these studies can be seen below.
