Ca/Mg-Plus™ supplies calcium and magnesium, along with specific support for the parathyroid gland. Calcium and magnesium are the most abundant intracellular cations, whose benefits are seen in multiple systems including the cardiovascular, nervous and musculoskeletal systems.* Regulated by the actions of calcitonin and parathyroid hormone, the inclusion of parathyoid glandular is an ideal combination to help maintain the critical ratio between calcium and magnesium.
