AceNano Calcium is processed by 'Dry process Nano-particle Pulverization', which pulverizing process is carried out under strictest and precise controlled environment, Therefore AceNano calcium remains "as-is" ingredients / property and its purest quality.
AceNano is made from Oyster shell which is like our bones and teeth, oyster shell is a biomineral, a combination of organic molecules - made by living organisms - and mineral components that organisms ingest or collect from their environment. The aragonite mineral in oyster shell is made of calcium carbonate, which marine animals form from elements abundant in seawater.
