- +73 naturally occurring micro-minerals plus potassium, boron, zinc, D3 and K2
- Sustainably harvested calcium
- Easier to swallow capsules vs large tablets
- Great for travel
- Whole food calcium; not mined from limestone rock
Sustainably Harvested from Clean Coastal Waters of North Iceland
Aquamin plant source calcium is sustainably harvested under strict controls established by the Icelandic government for extraction methods and quotas. Only the calcified algae are harvested; new growth plants are not disturbed.
Certified Naturals™ Calcium Magnesium capsules are an easy way of getting daily calcium requirements for those that have trouble swallowing large tablets.
plus Mg, K, B, Zn, D3, K2, and 73 extra micro-minerals
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.
Certified Naturals Calcium Magnesium Plus K2 capsule formula contains the unique plant-source calcium source known as Aquamin™. Aquamin™ is an award-winning, clinically studied ingredient sourced from the Icelandic red-algae Lithothamnion calcareum.
Aquamin™ calcium contains a complex of 73 micro minerals making it an ideal supplement for bone health. Certified Naturals™ also contains added magnesium, potassium, boron, zinc and important bone vitamins D3 and K2.
