Your bones need more than just calcium. In fact, human studies show that it takes a total of 13 minerals to make your bones stronger. In addition to calcium you also need magnesium, boron, copper, manganese, silicon, nickel, selenium, phosphorus, potassium, vanadium, zinc and strontium. You don’t need some of these minerals. You need ALL of them! And all 13 of these minerals naturally occur within a rare ocean algae – lithothamnium superpositum - AlgaeCal. This naturally occurring bone-building superfood is sustainably harvested from the pristine shoreline of a South American beach, sun-dried, and then milled into a powder. To this certified organic powder we add vitamins D3, K2-7, and C, plus additional boron and magnesium. These additions are the "Plus" in AlgaeCal Plus. And because it’s a natural plant-based product it’s easy to digest and there’s zero side effects. Our supplements are manufactured in the USA, in a cGMP-certified, FDA-inspected facility. Each bottle contains 120 vegetarian capsules for a 30-day supply. AlgaeCal is non-GMO and free from gluten, dairy, and soy.
