Doctor's Best High Absorption Magnesium 120 Tablets - Cardiovascular Health

For science-based nutrition in a dietary supplement that supports the heart‚ nervous system‚ and cellular energy production‚ try Doctor’s Best’s High Absorption 100% Chelated Magnesium. Each tablet provides elemental magnesium‚ which has been chelated with the amino acids glycine and lysine. As an essential mineral‚ magnesium plays many important roles. It helps cells produce metabolic energy‚ supports optimum nerve function and healthy bones‚ promotes muscle relaxation‚ and helps you maintain a healthy heartbeat. Glycine has been shown to be an efficient carrier for minerals by facilitating absorption in the intestinal tract. It’s used by the body to form collagen‚ a key protein in cartilage and connective tissue; this may ward off joint pain and stiffness. Meanwhile‚ lysine is an essential amino acid that assists gastric functioning. Magnesium acts a co-factor for metabolic enzymes. Perhaps most importantly‚ it works very closely with calcium to promote tooth and bone density. Weak bones can interfere with your everyday life by making you more susceptible to injuries caused by motion. Magnesium – Important for Everyone‚ Deficient in Many Loss of magnesium during food processing and low magnesium content in common processed foods are factors in a lack of magnesium. In addition‚ absorption of the mineral tends to decrease with age. The elderly may be susceptible to magnesium deficiency for a variety of reasons‚ including inadequate intake‚ poor absorption due to impaired gastrointestinal function‚ and the use of drugs such as diuretics that deplete magnesium stores from the body. A lack of magnesium may cause the visible signs of aging to appear more quickly‚ due to its impact on the cardiovascular and nervous systems‚ as well as on muscles and the kidneys. Women who take both synthetic estrogen and calcium supplements may be at risk for low blood levels of magnesium. Estrogen promotes the transfer of magnesium from blood to soft tissues; low blood magnesium may result if the ratio of calcium to magnesium intake exceeds 4 to 1. Magnesium supplementation is thus advisable for women taking these supplements. Unfortunately‚ a low magnesium status may often not be recognized‚ and many people of all ages who could benefit from supplementation go without it. Magnesium – The Versatile Mineral The average adult body contains anywhere from about 21 to 28 grams of magnesium. Approximately 60 percent of the body’s magnesium supply is stored in bone. Soft tissue‚ such as skeletal muscle‚ contains 38%‚ leaving only about 1–2% of the total body magnesium content in blood plasma and red blood cells. Magnesium works as a co-factor for over 300 enzymatic reactions in the body. Metabolism uses a phosphate-containing molecule called ATP as its energy source. Magnesium is required for all reactions involving ATP. ATP supplies the energy for physical activity by releasing energy stored in phosphate bonds. Skeletal and heart muscle use up large amounts of ATP. The energy for muscle contraction is released when one of ATP’s phosphate bonds is broken‚ in a reaction that produces ADP. Phosphate is added back to ADP‚ re-forming ATP. ATP also powers the cellular calcium pump‚ which allows muscle cells to relax. Because it participates in these ATP-controlled processes‚ magnesium is vitally important for muscle contraction and relaxation. By controlling the flow of sodium‚ potassium and calcium in and out of cells‚ magnesium regulates the function of nerves as well as muscles. The heart is the only muscle in the body that generates its own electrical impulses. Through its influence on the heart’s electrical conduction system‚ magnesium is essential for maintenance of a smooth‚ regular heartbeat. Magnesium may help your body cope with stress and increase the amount of antioxidants in your bloodstream. Magnesium intake is tied to skeletal bone health through several pathways. Under normal physiologic conditions‚ parathyroid hormone (PTH) secretion is low when magnesium intake is not adequate. Additionally‚ PTH resistance can develop. Adequate magnesium intake can support the normal function of PTH. Low magnesium intake is further associated with a disturbance in blood levels of the active metabolite of vitamin D‚ as well as an increase in cytokines‚ both of which may impact bone health. Numerous studies‚ large and small‚ have examined the relationship between magnesium and bone health. The dietary intakes of magnesium‚ potassium‚ fruits and vegetables are associated with increased bone density in the elderly. Research also suggest
