ingredient information
Caseinate is casein mixed with a metal (calcium caseinate, sodium caseinate). Like many other nutritional compounds, casein is typically bound to a metal since the molecule is more stable this way. Specifically, casein is most commonly bound to calcium (Ca2+) or sodium (Na+) since both of these metals are found naturally in milk, and tend to "stick" to the casein during the extraction process. Nutritionally, these compounds are basically interchangeable, as both forms of caseinate are effective protein sources. Source:
