The symptoms of leg cramps in the elderly are mainly caused by calcium deficiency. Therefore, if you want to take calcium tablets orally after leg cramps occur in the elderly, it is best to take calcium tablets containing vitamin D. Because vitamin D can promote the absorption of calcium, it can promote the absorption and utilization of calcium by the body to relieve the symptoms of cramps in the elderly. Because vitamin D can promote the absorption of calcium, oral intake can promote the absorption of calcium by the body, thus relieving the symptoms of cramps in the elderly. If you don’t get calcium tablets containing vitamin D, you can take calcium tablets orally with vitamin D orally, which can also absorb calcium very well. You can get more sunlight outdoors and eat foods with high calcium content, such as soy products, dairy products, shrimp, fresh fruits and vegetables and other foods to promote the absorption of calcium and relieve the symptoms of leg cramps.
