What the Evidence Says

✨ AI-generated · Qwen 3.6 · grounded in 1 source · methodology

Vitamin D3 is supported by strong evidence for maintaining bone health and supporting immune function. However, the high dosage of 10,000 IU may pose safety concerns regarding toxicity or hypercalcemia with long-term use. Users should monitor intake levels due to the risk of vitamin D overdose.
