Calcium is a large number of elements necessary for the human body. If the rate of calcium loss increases simply because of aging, you need to eat more foods with high absorbable calcium content, such as milk, eggs, sea rice, seaweed, tofu, spinach, mahjong, etc., as well as more dietary fiber, such as groundnuts, potatoes, yams, purple potatoes, celery, etc., to promote intestinal health and increase the amount of calcium absorption. Usually, you can take complex nutrient tablets every day, such as 21 gold vitamins, good storage, etc. to supplement the nutrients from food intake, you can take oral vitamin D or osteotriol to promote the absorption rate of calcium in the body and increase the amount of calcium absorption and deposition. Ensure sunbathing for more than 20 minutes a day to promote the synthesis of vitamin D in the body, which can slow down the rate of calcium loss. It is best to do appropriate physical exercise to enhance physical fitness, which can produce some benign stimulation to the body and slow down the rate of loss. If you are suffering from some diseases that cause increased calcium loss, you need to treat the original disease after diagnosis.
