Whether you keep a tub in your kitchen cupboard or need a sachet on the go, try our superior Osteo Collagen to maintain a healthy calcium balance. A healthy thyroid not only regulates energy output but it plays an essential role in regulating calcium levels in the blood, protecting against brittle bones and osteoporosis. So we have included important co-factors for thyroid protection such as iodine-rich kelp as well as selenium—an important antioxidant to defend against free radical damage generated by thyroid hormone production. Zinc is another essential mineral with important bone-supporting action. We add bioavailable magnesium to enhance healthy calcium uptake, as well as vitamin K2 which aids in calcium placement in bone rather than soft tissue. Additional minerals copper, manganese and boron work as important bone co-factors. Finally, to our custom nutrient blend we have added bioactive herbs such as nettle leaf—high in polyphenols and antioxidants—ginger, and horsetail, a traditional herb used in medicine since Greek and Roman times.
