See the technical phrasing
Daily supplementation with 1000 or 2000 IU of vitamin D3 for six months increases serum 25-hydroxyvitamin D concentrations to levels above 30 ng/mL without causing hypercalcemia in vitamin D-deficient overweight and obese children aged 10–18 years.
When a child takes vitamin D3 pills, the liver turns it into a form called 25-hydroxyvitamin D, which builds up in the blood. Higher doses lead to higher levels, and when levels reach above 30 ng/mL, the body stops making more active vitamin D that pulls calcium from bones, so calcium in the blood stays safe.
