Issue 11. How to Lower Vitamin D in Foods and Supplements (2007)

by J. C. Waterhouse, Ph.D.

Note: The Marshall Protocol uses a vitamin D receptor (VDR) activating medication, which, according to Dr. Marshall’s research, more effectively activates the VDR. See links at the end for more details.

If one chooses to lower their vitamin D intake, one can begin by only using calcium supplements without vitamin D (companies that have them include Solgar and Thorne, see There is only one multivitamin that has no vitamin D that I know of and it is Nature’s Life Vegetarian Mega Vita Min. For many people, individual nutrients, if really needed due to a deficient diet, may be preferable since they are more hypoallergenic (see Supplements that May Be Taken to Avoid Vitamin D– some may be cut into half or quarter to approximate the RDA). Cod liver oil has a large amount of vitamin D and most fish oils have some, even though some vitamin D may have been removed. It is also possible to find dairy products with minimal added vitamin D, particularly some organic brands in health food stores. Cheeses do not usually list the vitamin D that has been added. It has been found that those cheeses that mention 6% or less of Vitamin A usually have less vitamin D. Yogurt usually has added vitamin D, but I have found plain Straus Family yogurt to be free of added Vitamin D (this may change, so check label). If one doesn’t like plain yogurt, one can add fruit and a sweetener, such as honey or Splenda. Some cereals have added vitamin D, but if you look closely, you will find others that don’t (especially in health food stores). If one eats fish, one can reduce the amount of vitamin D by avoiding or reducing certain high fat fish, like salmon, herring, sardines, mackerel, herring and tuna. Farmed fish has considerably less vitamin D than wild caught fish and cod, haddock, plaice and shellfish also have less vitamin D (see: ). Egg yolks have some vitamin D and to avoid this, one can find cartons of egg whites (though many add vitamin D, so you may have to look at a few to find one without added vitamin D). Liver has vitamin D and can be avoided. Experience with the Marshall Protocol has shown some will feel better lowering their vitamin D intake, however some people who have had a high vitamin D intake may find that if they lower it a great deal, their immune system may start killing cell wall deficient bacteria and they may have some increase in symptoms due to bacterial die off (see Short Introduction to the Marshall Protocol).
