Thanks for your question Trudy. Both Fibro-Care and Fibro-Care Cal are meant to be complementary products to our Multi-Gold daily premium vitamin mineral complex. Yet each fulfill a specific EXTRA need for supplying additional magnesium (Fibro-Care) or additional bone building nutrients (Fibro-Care Cal) as a stand alone product. So it is not that we omitted nutrients. We built a program of products to be used together and Multi-Gold is the foundation of the program. One additional factor is we use Albion organic chelate minerals which take up more space in a tablet or capsule than magnesium oxide or calcium chloride (inorganic salts). So you are getting better and more bioavailable nutrient benefits with TyH.
