The heart health contraindications of calcium relate to those supplements derived from rock or limestone. Our calcium is derived from a natural food source – a type of seaweed, which is more bioavailable in the body and is readily utilised. Unfortunately, the body struggles to absorb rock-derived calcium, which is therefore then free to travel around the circulation and become deposited in arterial plaque. It is this calcified arterial plaque clogging arteries that leads to an increased risk of heart attack and stroke. Dr Nina Bailey explains in more detail here.
