In addition, the presence of enough calcium in the body protects the bones and teeth from the accumulation of lead, a very toxic metal. Taking calcium together with vitamin D seems to reduce the risk of colon and rectal cancer. \ \ Vegetarians, if they do not consume milk and dairy products, may suffer from low calcium levels, not only because they lack a rich source of the mineral, but also because their diet is usually rich in acids (phytic, oxalic) that bind with calcium and reduce its absorption. \ \ People who avoid milk and dairy products, due to a lack of the enzyme lactase and the resulting intolerance, are at risk of calcium deficiency if they do not eat foods rich in calcium or do not take calcium supplements. \ \ Not all age groups retain the calcium contained in foods equally well. Infants have the highest absorption (60%), while in older people the absorption rate decreases dramatically. \ \ other factors that negatively affect calcium absorption are low vitamin D levels, a lack of hydrochloric acid in the stomach, a sedentary lifestyle, while high protein and coffee consumption causes increased calcium excretion in the urine. \ \ the best way to increase calcium absorption from dietary supplements is to take it with vitamin D or (even better) with a complete range of vitamins and minerals. \ \ the optimal daily calcium intake (from foods and supplements) ranges between 1000 and 1500mg, while the table below shows the recommended doses for treating specific conditions, according to the practice of many American alternative doctors. \ \ problem - recommended dose: \ \ broken / cracked bones: 1000-2000 mg \ \ high blood pressure: 1000-1500 mg \ \ osteoporosis: 1000-2000 mg \ \ magnesium \ \ magnesium (like phosphorus and calcium) is essential for bone and tooth health, while, together with calcium, they regulate muscle activity: magnesium is a muscle relaxant, while calcium is a muscle stimulant. \ \ magnesium is essential for the metabolism and synthesis of proteins, for the activation of a large number of enzymes and for the passage of sodium and potassium through cell membranes. \ \ adequate levels of magnesium in the blood protect the cardiovascular system and prevent cardiac arrhythmias and, possibly, strokes. \ \ taken as a supplement, magnesium can help with insomnia, premenstrual syndrome, cramps, as well as cardiovascular problems, such as hypertension or angina, due to spasms of the coronary artery. \ \ according to prominent American cardiologists, magnesium also: \ \ \ helps the heart push a larger volume of blood into the arteries, without the need for additional oxygen. \ \ relaxes constricted vessels, allowing blood to flow more freely. \ \ prevents platelets from sticking together, thus reducing the chances of clot formation and artery blockage. \ \ reduces bad (LDL) and increases good (HDL) cholesterol. \ \ magnesium supplements help type ii diabetics (non-insulin dependent) to regulate their sugar more easily, allowing the reduction of antidiabetic medications and, in some cases, their discontinuation (this should be done with the cooperation of the treating physician). in type i diabetics, magnesium is much less effective. \ \ magnesium strengthens tooth enamel, while it is important for bone density.
