Science & Research
Verifiable Science
Vitamin D promotes intestinal calcium and phosphorous absorption and reduces urinary calcium loss, essential mechanisms for maintaining proper calcium levels in the body and healthy bone composition.1 Research indicates that it also promotes cellular health, including support for breast and prostate tissue, in part by helping to maintain healthy blood vessel function, supporting immune cell activity and maintaining healthy cell metabolism.2-4 A role for vitamin D in supporting colon health by promoting healthy cellular function also has been suggested.5 Vitamin D's role in immune health has long been established; vitamin D receptors are found in a number of immune cells, including lymphocytes and macrophages, maintaining healthy immune cell activation.6 Vitamin D also supports cardiovascular function in some individuals.7 Liquid vitamin D3 is offered in a base of medium-chain triglycerides to support absorption.‡
