What this claim means

See the technical phrasing

In vitamin D-deficient overweight and obese children aged 10–18 years, daily supplementation with 2000 IU of vitamin D3 for six months improves insulin sensitivity and reduces fasting glucose concentration by approximately 2.7 mg/dL compared to daily supplementation with 600 IU of vitamin D3.

Why this might work
Supported
based on 1 study

When vitamin D levels rise, it activates receptors in muscle and fat cells, which increases the number of glucose transporters on the cell surface. This allows more sugar to leave the blood and enter the cells, lowering blood sugar and reducing the amount of insulin needed to manage it.
