Algaecal plant-based calcium

Hand-harvested from a beach in South America, AlgaeCal naturally contains all 13 minerals that make bones strong. Besides calcium, this natural superfood has magnesium, potassium boron, copper, manganese, silicon, strontium, nickel, phosphorus, selenium, vanadium, and zinc. 

In human clinical trials, these 13 nutrients have been shown to increase bone density — even for people in their 60s, 70s, and 80s. (And the characteristics of human bone are best approximated by the properties of dog bone.)¹

AlgaeCal's marine algae draws all the bone-building minerals from sea water and absorbs them for it's metabolic needs. The algae is lithothamnion superpositum; a species of red coralline algae found off the South American coast. 

Taxonomically, this is red algae in the Rhodophyta phylum, from the Corallinales order (also known as Algas calcareas), the Lithothamnion genus, and one of the 103 species within that genus.

Red algae is aptly named because the algae reflects red light, thanks to its pigment phycoerythrin. Coralline algae also known as (Algas calcareas) secretes a coral-like hard shell of carbonate around itself, like coral does. 

Red algae is generally more complex than most other algaes, both at a cellular and structural level.

Algas calcareas has a 180-day lifecycle. It attaches itself to seaweed on the ocean floor and hangs out for six-months, just growing and doing its own thing. Eventually, the then kiwi-sized algae detaches from the seaweed and washes ashore.

That’s the key part — the algae washes up onto the beach naturally. Because the algae comes to shore, it doesn't have to be dredged out of the ocean. Dredging disrupts marine life and unsettles the ocean floor, which negatively impacts the area’s ecology.

So, to limit impact on the area, the algae is harvested by hand from the shores of a remote area in South America. A team of trained locals live-harvest this marine algae from the beaches at low tide within 48 hours of being exposed to the sun. This ensures all of the minerals and nutrients are intact. The crop is rotated from beach to beach to be sure to not interfere with the natural cycle of marine algae.

After it’s collected, the marine algae is washed with fresh ionised water and then sun-dried. The algae is then milled down to powder form to become the raw version of AlgaeCal. To ensure quality and safety, every batch of AlgaeCal powder is tested for microbial activity and mineral content.

There is no chemical treatment and no additives or extractions that might create impurities in the raw form. Algas calcareas is a completely natural product.
