Magnesium Blocks Calcification of Arteries Magnesium converts vitamin D into its active form so that it can help calcium absorption. All calcium tablets will have some percentage vit-d, coz with out vit d , body cant absorb calcium. So magnesium controls calcium and avoid calcification in arteries. Earlier scientists said calcium deficiency was cause of osteoporosis but now research says magnesium is more important than calcium in controlling this. Magnesium stimulates a particular hormone, calcitonin, which helps to preserve bone structure and draws calcium out of the blood and soft tissues back into the bones, preventing osteoporosis, some forms of arthritis and kidney stones. Calcitonin (also known as thyrocalcitonin) is a 32-amino acid linear polypeptide hormone that is produced in humans primarily by the parafollicular cells (also known as C-cells) of the thyroid, and in many other animals in the ultimobranchial body. It acts to reduce blood calcium (Ca2+), opposing the effects of parathyroid hormone (PTH). Calcitonin has been found in fish, reptiles, birds, and mammals. Its importance in humans has not been as well established as its importance in other animals, as its function is usually not significant in the regulation of normal calcium homeostasis. It belongs to the calcitonin-like protein family. The hormone participates in calcium (Ca2+) and phosphorus metabolism. In many ways, calcitonin counteracts parathyroid hormone (PTH). More specifically, calcitonin lowers blood Ca2+ levels in three ways: Inhibits Ca2+ absorption by the intestines Inhibits osteoclast activity in bones Inhibits renal tubular cell reabsorption of Ca2+ allowing it to be excreted in the urine However, effects of calcitonin that mirror those of PTH include the following: Inhibits phosphate reabsorption by the kidney tubules[ In its skeleton-preserving actions, calcitonin protects against calcium loss from skeleton during periods of calcium mobilization, such as pregnancy and, especially, lactation. Other effects are in preventing postprandial hypercalcemia resulting from absorption of Ca2+. Also, calcitonin inhibits food intake in rats and monkeys, and may have CNS action involving the regulation of feeding and appetite.
