How much Sun do we need to get Vitamin D? Vitamin D levels vary naturally with the seasons. In summer, most people make enough Vitamin D because UV levels are high and people spend more time outdoors. In summer, most Victorians would need just a few minutes of sun exposure mid-morning or mid-afternoon, with best time, around 12 pm for adequate Vitamin D levels. In winter, we can get Vitamin D from diet and supplements.
Please remember, that the body can only absorb a limited amount of vitamin D at a time. Spending extra time in the sun will not increase Vitamin D levels, but will increase your risk of skin cancer.
