Together"s calcium supplement is complete in a marine multimineral complex providing bioactive calcium, magnesium and 72 other trace minerals. Our bodies are able to recognise minerals with ease when they"re taken from natural and complete sources rather than synthetically created. This means that we identify and absorb all that natural goodness far more effectively. We harvest our seaweed from the clean and pristine waters off the coast of Iceland. We simply wash, dry and mill the seaweed without the use of chemicals. This way we"re left with a clean natural calcium, just the way it should be.
