Formulation Notes

The next generation of Calcium from the Sea has been reformulated to reflect the latest in nutritional science and to provide a superior source of calcium for those who prefer animal free diets. Vitamin K2 MK-7 has been added to assume higher mineral absorption into the bones and avoid calcification of soft tissue. Vitamin D has been increased and changed to cholecalciferol because it is the best form for ultimate utilization in the body.

Calcium from the Sea is most suitable for vegetarians since all its mineral content is derived from seaweeds and algae.

Hypoallergenic: This product does not contain soy, milk, eggs, fish, Crustacean shellfish, tree nuts, peanuts, wheat, yeast, salt, preservatives, artificial color, flavor, or fragrances.

Additional Information

Organic minerals from plants are far more available to the body than non-organic forms found in most supplements.
