Mechanism of action

1

Natural Mineral Synergy

Calcium absorption enhanced by phosphorus (forms hydroxyapatite); magnesium supports calcium metabolism; potassium reduces calcium excretion; zinc supports bone enzymes.

2

Dairy-Source Bioavailability

Milk minerals naturally bound to dairy proteins; absorption pattern similar to dairy consumption.

3

Bone Mineralization

Calcium + phosphorus form hydroxyapatite — primary bone mineral; multi-mineral support comprehensive bone formation.
