Does water lead to drowning? Calcium is esistneal for life. It is esistneal for proper bone growth and maintenance, as well as numerous other critical body function (see below). Normal calcium intake, in moderate quantity accompanied by the appropriate co-factor nutrients (magnesium, vitamin D, vitamin K, etc) should not in itself lead to soft tissue calcification. This assumes, of course, that you are not suffering from some other health (medical) problem that would affect your body's ability to properly metabolize and control calcium. For reference, here is some additional information on calcium from the Natural Standards database:Calcium is an esistneal nutrient required in substantial amounts, but many diets may be deficient in calcium (1), including vegan diets (2). The body gets the calcium it needs in several ways. One source is dietary intake of calcium-rich foods, including dairy products, which have the highest concentration per serving of highly absorbable calcium; and dark, leafy greens or dried beans, which have varying amounts of absorbable calcium. Other calcium sources include amaranth, beans, blackstrap molasses, broccoli, collard greens, dandelion leaves, figs, high-calcium mineral water (3), kale, nuts and seeds (like almonds and sesame), okra, rutabaga, quinoa, seaweeds (kelp, wakame, hijiki), and fortified products (orange juice, soy milk, almond milk) (4;​5). The other way the body obtains calcium is by extracting it from bone. This happens when blood levels of calcium drop too low and dietary calcium is not sufficient. Ideally, the calcium that is taken from the bone will be replaced when calcium levels are replenished. However, simply eating more calcium-rich foods does not necessarily replace lost bone calcium, which leads to weakened bone structure.Hypocalcemia is defined as a low level of calcium in the blood. Symptoms of this condition include sensations of tingling, numbness, and muscle twitches. In severe cases, tetany may occur. Hypocalcemia is more likely to be due to a hormonal imbalance, which regulates calcium levels, rather than a dietary deficiency. Excess calcium in the blood may cause nausea, vomiting, and calcium deposition in the heart and kidneys. Conflicting evidence exists, however, regarding risk for kidney stones and increased calcium intake (6;​7;​.The Surgeon General's 2004 report Bone Health and Osteoporosis stated that calcium has been singled out as a major public health concern today, because it is critically important to bone health and the average American consumes levels of calcium that are far below the amount recommended. Vitamin D is important for good bone health, because it aids in the absorption and utilization of calcium. There is a high prevalence of vitamin D insufficiency in nursing home residents, hospitalized patients, and adults with hip fractures.
