I'm not impressed with this study I came across. The Twinlab that didn't absorb worth a shit is ranked 48. Absorption wasn't a criteria by this study. If the nutrients don't absorb how the hell can it even be ranked. Minor detail.
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)
