Nephrologist Warns Excessive Vitamin D Linked to Kidney Stones

Nephrologist Borja Quiroga has issued warnings regarding the potential for vitamin D to contribute significantly to the development of kidney stones.

The medical professional highlighted that uncontrolled use of vitamin D supplements can lead to severe renal complications, including the risk of renal failure.

The concern stems from the way excessive levels of the vitamin affect the body’s mineral balance. Specifically, the risk is linked to hypercalcemia, a condition characterized by an abnormally high concentration of calcium in the blood.

According to reporting on Quiroga’s observations, the impact of excessive supplementation can be severe. He has noted seeing patients who arrived at his clinic with kidneys full of stones.

While vitamin D is a necessary nutrient for overall health, the transition from a beneficial supplement to a health risk occurs when intake is not professionally monitored or managed.

The findings emphasize that the lack of medical oversight when taking supplements can lead to the accumulation of kidney stones, potentially compromising long-term renal function.

Medical experts suggest that the risks associated with vitamin D are most pronounced when supplements are taken without a confirmed deficiency or without the guidance of a healthcare provider to ensure safe dosing levels.
