钙的吸收率是指可以被机体吸收利用的比例。吸收率越高,人体获得的钙越多(摄入钙的量相同时)。因此,吸收率是衡量补钙产品好坏的重要指标之一。很多产品都标榜自己的吸收率高,然而据现有资料,各种不同钙来源的钙剂中,钙的吸收率基本相同,多在30％左右。例如,碳酸钙的吸收率为39％,葡萄糖酸钙27％,乳酸钙32％,草酸钙30％,牛奶中的吸收率为31％。考虑到试验操作和现实生活中的具体情况,专家们认为,50％的吸收率仍然可信,然而某些产品宣传说吸收率高达96％,这就十分
The absorption rate of calcium refers to the proportion that can be absorbed by the body. The higher the rate of absorption, the more calcium the body receives (the same amount of calcium intake). Therefore, the absorption rate is a measure of the quality of calcium products, one of the important indicators. Many products are advertised their absorption rate is high, but according to available information, a variety of calcium sources of calcium, the absorption rate of calcium is basically the same, more than 30%. For example, the absorption rate of calcium carbonate is 39%, calcium gluconate 27%, calcium lactate 32%, calcium oxalate 30%, and the absorption rate in milk is 31%. Taking into account the experimental operation and the actual situation in the real life, experts believe that 50% of the absorption rate is still credible, but some products that the absorption rate as high as 96%, which is very
