Tag: Vitamin d toxicity symptoms

While vitamin D toxicity is rare, it can occur from excessive supplementation. This can lead to serious health complications due to dangerously high levels of calcium in the blood, a condition called hypercalcemia.

According to the National Institutes of Health, the recommended daily intake of vitamin D for most adults is 600–800 IU, while the safe upper limit is 4,000 IU. Taking 7,000 IU of vitamin D, therefore, exceeds this safe upper limit and carries potential risks, particularly if done long-term.
