Vit A increases transferrin - higher doses can be detrimental to anyone low in iron, asthmatics, etc. I do not recommend vit A in this dose because it is too effective - used regularly, it causes me to get breathless (in a very unpleasant way) and I end up having to supplement other things to compensate (when they're normally not necessary). Suggest limited/occasional use only. I want a natural vit A, however it seems impossible to find one in lower doses, especially one that isn't cod.

Vitamin D & Vit A as Retinol: More recent research has discovered that the ratios of these two vitamins may be of paramount importance in order to extract optimal health benefits, and unfortunately, modern cod liver oil does not supply these vitamins in healthy ratios to each other. People who took vitamin A supplements in cod liver oil, or in supplements, had an 18 percent increase in death rates. Cod liver oil that is clearly excessive in vitamin A as it only has 3 to 60 units of vitamin D per tablespoon but between 150 and 12,000 times as much vitamin A. Both vitamins are essential to obtain optimal health benefits, however, the ratios can become dangerously unbalanced -- much like the omega-3/omega-6 balance, which has become inversed in our modern diet. Cod liver oil is a highly processed food that was never consumed by humans prior to recent times. Dr. John Cannell, of the Vitamin D Council, recommends not taking vitamin A as retinol, (as in cod liver oil), because the vitamin A blocks the positive actions of vitamin D. Dr. Cannell raised questions about the efficacy of cod liver oil due to its highly variable and frequently excessive amount of vitamin A. Typically modern cod liver oil contains far less vitamin D than it used to, due to the deodorization process used today which removes much of this essential nutrient. Dr. Cannell and other prominent researchers believe the vitamin A contained in most cod liver oil is excessive, and can reduce the effectiveness of vitamin D by inhibiting the binding of its active form to your DNA, effectively preventing its ability to regulate the expression of your vitamin D-responsive genes.
