  3. Magnesium – New studies show that supplementing magnesium with calcium increases bone mineral density.3 The AlgaeCal formula contains 350 mg of magnesium where OS-Cal only contains 40 mg in the recommended daily serving. – more about the Benefits of Magnesium
  4. Trace Minerals – AlgaeCal naturally contains 73 trace minerals from algae, the Oscal formula has added zinc, copper and manganese to their formula synthetically.
  5. Tablets – OS-Cal Ultra comes in tablet form rather than veggie capsules, and tablets are a less bio-available delivery system.4 The tableting requires many additives of questionable value such as “cellulose, crospovidone, FD and C blue No. 2, red No. 40, and yellow No. 6, Magnesium Stearate, polysorbate, povidone, sodium croscarmellose, starch, sucrose, titanium dioxide, triacetin”.
