This activated Vitamin D works to absorb calcium from your food, ultimately leading to bone growth and strength.

这种活性维生素D可以从食物中吸收钙，影响骨骼生长和骨强度。

In chronic kidney disease, there's less activated vitamin D, so less calcium is absorbed into the blood, resulting in hypocalcemia - low calcium levels.

慢性肾病中，活化的维他命D减少，因此钙吸收入血减少，导致低钙血症，即血钙水平低。

Normally, the kidney helps to activate vitamin D which helps to increase absorption of calcium from the diet.

正常情况下钙辅助活化维生素D，后者有利于饮食中钙的吸收。
