Sun Exposure Vitamin D Calculator

To obtain sufficient vitamin D, aim for 15-30 minutes of sun exposure on arms, legs, face, and hands 2-3 times weekly. In about 10 minutes, you may produce 1,000-3,000 IU of vitamin D. For 10,000 IU, it takes around 30 minutes to 2 hours, depending on location. Factors like clothing and sunscreen can block absorption, so balance sun and supplements.
