Calcium
Calcium is required for heart health, muscle function, nerve transmission, intracellular signaling and hormonal secretion. It is less than 1% of total body calcium that supports these critical metabolic functions. Serum calcium is very tightly regulated and does not fluctuate with changes in dietary intakes. The body uses bone tissue as a reservoir for calcium, as well as a source of calcium, to maintain constant concentrations of calcium in blood, muscle and intercellular fluids. The remaining 99% of the calcium supply in the body is stored in the bones and teeth, serving as support for their structure and function.
Magnesium
More than 57% of the population does not meet the United States Department of Agriculture requirements for magnesium in their diet. Magnesium is a cofactor in over 300 enzyme systems and is integral to many processes in the body, including protein synthesis, muscle and nerve function, and maintaining blood glucose control and blood pressure regulation. It contributes to the structural development of bone and is required for the synthesis of DNA, RNA and the antioxidant, glutathione. Magnesium also plays a role in the active transport of calcium and potassium ions across cell membranes, a process that is important to nerve impulse conduction, muscle contraction and normal heart rhythm.
Zinc
Zinc is fundamental to the activity of over 100 enzymes and supports immune function, protein synthesis, tissue regeneration and healing, DNA synthesis and cell division. During pregnancy, infancy and childhood, the body needs zinc for proper growth and development. Zinc also helps boost tissue repair and is important to adequate functioning of the senses of taste and smell. Daily intake of zinc is necessary to maintain adequate levels within the body because the body has no specialized zinc storage system.
Selenium
Selenium has structural roles, as well as enzymatic functions. It is best-known as an antioxidant and catalyst in the production of active thyroid hormone. Selenium is essential in the balance and support of immune system function. Selenium promotes sperm motility, supports positive mood, antioxidant status, inflammation balance and heart health.
Potassium
Potassium is an electrolyte mineral that carries an electric charge. It is critical to maintaining electrolyte balance in the body. Potassium can contribute to heart and bone health and is an integral part of muscle contraction and muscle building.
