Calcium-Magnesium from Plant Source Aquamin - 240 Capsules

Calcium-Magnesium from Plant Source Aquamin - 240 Capsules



 A plant-sourced, whole food, safer Calcium

Limestone-based calcium supplements may increase risks to the heart by contributing to arterial calcification, according to recent studies. To help reduce this risk, it's important to choose a food source calcium that is well-absorbed by the body. A food source, plant-based calcium such as Aquamin® from Icelandic red algae, is a better calcium!

 Many calcium supplements are mined from limestone - a sedimentary rock. After processing, this material contains only a single mineral - calcium, which is poorly absorbed and contributes to arterial calcification


Certified Naturals Calcium Magnesium with Aquamin is a whole food calcium that is not mined from rock. It's uniquely different than sedimentary rock limestone calcium.
