The calcium in this formula does not come from ground rock or oyster shell, the source of most calcium carbonate on the market. It comes from Lithothamnion calcareum, a coralline red algae that builds a hard, calcified skeleton the way coral does, slowly mineralizing over years in cold Icelandic waters before being harvested. That slower, biological process is why it arrives already carrying dozens of trace minerals alongside the calcium, rather than calcium alone.

The body absorbs calcium more efficiently in smaller doses, so splitting the four capsules across two meals rather than taking all four at once, two with breakfast and two with dinner, gets more of it actually used.

If any medication is part of the daily routine, particularly thyroid medication or certain antibiotics, it is worth taking this a few hours apart from them, since calcium can interfere with how well those are absorbed. Pairing it with a vitamin D3 and K2 formula is a natural next step, since D3 supports calcium absorption and K2 helps direct it toward bone rather than soft tissue.
