钙作为人体第五大必需元素  ，在孕期发挥着尤为关键的作用 。妊娠晚期胎儿骨骼快速发育  ，每日需从母体摄取约200-300mg钙  ，导致孕妇钙需求量显著增加 。同时  ，孕期特殊的生理变化进一步加剧钙代谢失衡：血容量扩张使血钙浓度相对降低30%-40%  ，肾小球滤过率提高导致尿钙排泄量增加50% 。这些因素共同作用  ，使孕妇普遍处于生理性低钙状态 。研究显示  ，约60%的孕妇存在钙摄入不足  ，这不仅影响胎儿骨骼发育  ，还可能增加妊娠高血压和骨质疏松的风险 。因此  ，科学补钙（酮戊二酸钙Calcium ketoglutarate、赖氨酸钙Calcium Lysinate）对保障母婴健康具有重要意义 。

Calcium nutritional requirements during pregnancy: Characteristics of calcium metabolism during pregnancy and the importance of supplementation (Calcium ketoglutarate, Calcium Lysinate)

As the fifth essential element for the human body, calcium plays a particularly critical role during pregnancy. In the late pregnancy, the fetal skeleton develops rapidly, and the mother needs to take in about 200-300 mg of calcium per day, which leads to a significant increase in the calcium demand of pregnant women. At the same time, the special physiological changes during pregnancy further aggravate the imbalance of calcium metabolism: the expansion of blood volume reduces the blood calcium concentration by 30%-40%, and the increase in glomerular filtration rate leads to a 50% increase in urinary calcium excretion. These factors work together to make pregnant women generally in a physiological low calcium state. Studies have shown that about 60% of pregnant women have insufficient calcium intake, which not only affects the fetal skeleton development, but also may increase the risk of pregnancy-induced hypertension and osteoporosis. Therefore, scientific calcium supplementation (Calcium ketoglutarate, Calcium Lysinate) is of great significance to ensure the health of mothers and babies.
