<<Disclaimer: Verify this information before applying it to your situation.>> The "dry", "water-based", or "water-soluble" forms of the fat-soluble vitamins: A, D, E, & K, are actually "water-dispersed", meaning that an emulsifier is included in the formulation so that the fatty vitamin is dipersed into many tiny fat droplets. Hopefully your digestive system has a greater opportunity to absorb it than if it went through your system in a few large oily drops. Most health food stores I have been to have vitamins labeled as GF. Here are some examples from the several brands that are available: Allergy A & D Caps Twinlab no barley, wheat,... Dry E 400 I.U. Nature's Life no gluten, wheat,... Vitamin K 100 KAL no gluten, wheat,... Their addresses are: Twin Laboratories, Inc. Ronkonkoma, NY, 11779 Nature's Life, Garden Grove, CA, 92641 KAL, Inc. Woodland Hills, CA, 91365 I don't think it is possible to create truly water-soluble forms of A, D, E, & K, and I do not know if they are metabolized differently, but I personally feel the "water-dispersed" form is more effective for my body.
