3A Calcium (AAACa) is an ionic calcium from Japan comprised of calcium oxide and
calcium hydroxide. AAACa is also potentiated with HAI™ (heated algal ingredient), an amino acid complex from super-heated hijiki seaweed. Tiny amounts of HAI have been scientifically shown to significantly increase calcium absorption. In one study, the improvement was up to 4X greater. These two natural ingredients are only available in 3A Calcium.*
3A Calcium provides superior calcium absorption and parathyroid modulation.* Backed by 30 years of clinical research and 30 published, scientific articles, 3A Calcium has shown a consistent, significant increase in bone density.*
