Doctor's answer (1)
Dr. Wang Lei
You can take vitamin D when supplementing calcium. Its function is to promote renal reabsorption and regulate calcium levels in the blood. The body's vitamin D mainly comes from diet, and secondarily from synthesis in the skin induced by ultraviolet radiation from sunlight. During winter, reduced outdoor activities lead to decreased vitamin D production in the skin; therefore, it is important to appropriately supplement vitamin D to ensure adequate calcium absorption by the body.
