Microcrystalline Hydroxyapatite (MCHA) from Australia

cow-smallPM NextG Cal® and PM NextG Cal® Kids use pure Australian hydroxyapatite (in microcrystalline form) (or MCHA). It is a concentrated MCHA derived from young Australian bovine bone. It contains calcium and phosphorous at the natural ratio in bone, as well as many other trace elements and collagen, also found naturally in bone. The material is processed at biological temperature to maintain the integrity of the component molecules.

Australia has had no incidence of infectious diseases that can sometimes be contracted from meat and its by-products, such as Bovine Spongiform Encephalopathy (BSE, or “Mad Cow” disease).  Border authorities in Australia have strict protocols in place to prevent entry of this type of disease into the country.  This means that the MCHA in PM NextG Cal® and PM NextG Cal® Kids may be among the safest sources of MCHA in the world.  Further information about border quarantine regulations and food safety standards in Australia can be found by clicking onto this link.
