Spending even a short time in the sun can provide the body with all of the vitamin D it needs for the day. According to the Vitamin D Council, this could be: 15 minutes for a person with light skin. a couple of hours for a person with dark skin.
70% skin exposure (swimsuit only) 1400-2800 IU. 46% skin exposure (shorts and t-shirt) 800-1600IU. 5-12% skin exposure (hands and face) 100-200 IU.
The researchers took into account the amount of clothing and the season of the year. In spring and summer, 25 percent of the body (the hands, face, neck and arms) is exposed to the sun, and in these seasons, about 8 to 10 minutes of sun exposure at noon produces the recommended amount of vitamin D.
According to the national Institutes of Health, between five and 30 minutes of sun exposure to your unprotected face, arms, legs or back between the hours of 10 a.m. and 3 p.m. two to three times every week is enough for your body to produce all of the D3 it needs. Sunscreen can block vitamin D production.
Generally, it takes a few weeks of taking daily vitamin D supplements for vitamin D levels in the body to rise. Each 1,000 IU of vitamin D3 taken daily is expected to raise blood levels of 25(OH)D by 10 ng/ml after a few weeks.
What About If I'm Wearing Clothes? A common misconception is that you can get vitamin D from the sun through clothing. This is not true, as the only way to trigger the chemical reaction that results in vitamin D production is for sunlight to reach your skin directly.
Therefore, conditions that affect the gut and digestion, like celiac disease, chronic pancreatitis, Crohn's disease, and cystic fibrosis, can reduce vitamin D absorption.
According to Yale Medicine, vitamin D derived from sunlight is no better than the Vitamin D we get from supplements. They are functionally the same and can both boost vitamin D levels to a healthy range. The body can use supplemental and sunlight derived vitamin D in exactly the same way.
Sunshine will raise levels of active Vitamin D within about 8 hours – depending on the strength of the sun and your level of absorption. Vitamin D3 supplements are thought to raise vitamin D levels in the bloodstream in around 24 hours.
Q. Am I still getting vitamin D when I'm outside on a gray, cloudy day? A. Just as it is possible to get a sunburn on an overcast day, it is possible to get the ultraviolet-B radiation needed for the skin to synthesize vitamin D even when skies are cloudy and gray.
Sun exposure is the most important natural source of vitamin D and I would say 10-15 minutes in the early morning sun, when its UVB rays are most intense, should do the job. You could step into your balcony, terrace, garden, the neighbourhood park or any spot outdoors, with your upper and lower limbs uncovered.
Taking it with a fruit, tea, coffee, or in-between meals won't let the absorption happen,” she says. “For better absorption of vitamin D, you must include vitamin K, magnesium, and zinc in your diet. They speed up the absorption procedure and reduce your likelihood of being vitamin D deficient,” she suggests.
Symptoms of vitamin D deficiency may include:
Fatigue. Not sleeping well. Bone pain or achiness. Depression or feelings of sadness.
Recent findings: Low vitamin D levels are associated with increased symptoms of depression and anxiety. For this reason, vitamin D screening should be performed in the prevention and treatment planning of these mood disorders.
Vitamin D deficiency can lead to a loss of bone density, which can contribute to osteoporosis and fractures (broken bones). Severe vitamin D deficiency can also lead to other diseases: In children, it can cause rickets. Rickets is a rare disease that causes the bones to become soft and bend.
Most of this UVB radiation is absorbed in the epidermis and as a result when exposed to sunlight most of the vitamin D3 that is produced in the skin is made in the living cells in the epidermis.
Although there is no scientific evidence that vitamin D can have a direct effect on the under-eye area, it is believed that puffy eyes and dark circles prevail in people deficient in vitamin D, particularly females aged 40+.
You cannot wash vitamin D produced in the skin off!
So, no worries if you take a shower after spending some time at the beach – you'll do a good job of washing the sand off, but that vitamin D (which was produced in the deeper layers of the skin) will remain.

In summer and spring, with 22% of uncovered skin, 1000 IU vitamin D doses are synthesized in 10-15 min of sun exposure for adults.
The best time to soak yourself in the sun to get the maximum vitamin D is between 10 am to 3 pm. At this time, the UVB rays are intense and it is also said that the body is more efficient in making vitamin D at this time.
