I read somewhere(I can't seem to find it now)that you need to use a 100% calcium w/D-3(I think it was a rep-cal product, phosphorus free) and a beta carotene as a vitami supplement? My Vet recommended a Natural Calcium(animal essentials)product. In each teaspoon it has 1000mg of calcium, 100mg of magnesium, 14mg of sulfur, 3mg of potassium, 24mg of phosposrus, 75mcg of borum, 66mcg of zinc, 60mcg of iodine, and 3mcg of selenium. I am confused at what to do? Need help.
