Vitamin D from the Sun: All You Need to Know

Discover Vitamin D benefits for the skin and the safe ways to get it from the sun.

What is Vitamin D?

What does Vitamin D do?

Vitamin D is a fat-soluble vitamin that supports overall health by helping the body absorb calcium and by supporting the immune system, nerves, and muscles1,2. Vitamin D is also associated with helping to support mood, as studies have shown that having a Vitamin D deficiency has been associated with anxiety and depression symptoms3, though it is not scientifically proven to treat or cure these conditions2
What are the benefits of Vitamin D?

Is Vitamin D good for the skin?

Vitamin D benefits include supporting vital body functions and being essential for bone health. Having sufficient calcium and Vitamin D helps keep bones strong and helps to prevent conditions like osteoporosis where bones become brittle and are more prone to fracture1. Vitamin D deficiency is also associated with weak and painful muscles, which can contribute to loss of balance and falls, further increasing risk of injury if bones are already fragile.  

In addition to being an important nutrient for your overall health, Vitamin D is also beneficial to skin as it helps support the immune system, helps inhibit DNA damage4  (a common cause of premature aging in the skin due to free radicals) and helps to reduce inflammation2.

What are the symptoms of Vitamin D deficiency?

People with a Vitamin D deficiency are often asymptomatic5. Some symptoms of more severe or prolonged Vitamin D deficiency may include: 

  • Bone pain5 
  • Joint pain5 
  • Muscle pain, twitching, or weakness5 
  • Fatigue5 

If you think you might have Vitamin D deficiency, ask your doctor for advice. 

How to get Vitamin D

Vitamin D comes from 3 main sources: 

  • Nutrition1 
  • Sunlight1 
  • Dietary Supplements1

Vitamin D in food:

There aren’t actually very many foods that naturally contain Vitamin D, so a lot of the foods and beverages we consume are fortified with it, such as breakfast cereals, milk (both dairy and plant-based), orange juice, and other products. Foods that naturally contain Vitamin D include fatty fish, egg yolks, beef liver, and mushrooms6.  

Vitamin D from the sun

Sunlight is considered the best way to acquire Vitamin D6. Our bodies can naturally produce Vitamin D when exposed to the sun. There are factors that can decrease the Vitamin D intake from this source: pollution, clouds, age, having a dark skin tone and spending a lot of time indoors (your skin doesn’t produce Vitamin D from sunlight that comes through the window1).  

However, unprotected sun exposure has its drawbacks, including an increased risk of skin cancer. Using sunscreen unfortunately limits Vitamin D production, but in order to protect yourself from the harmful effects of the sun, it’s important to wear a broad-spectrum sunscreen if you’re going to be in the sun for any longer than a few minutes. 

Is there enough Vitamin D in the winter sun?

In colder climates in the winter months, it’s common to not to get enough sun exposure, compounded by the fact that less UVB radiation reaches the skin due to the angle of the sun and ozone layer UVB absorption7

Can you get too much Vitamin D?

You cannot get too much Vitamin D from the sun, as our bodies regulate the produced intake6, however, it is possible to have excess Vitamin D from taking supplements, and this can cause problems1

Some symptoms of excess Vitamin D include: 

  • Muscle weakness 
  • Nausea and vomiting 
  • Increased urination and thirst 
  • Confusion 
  • Kidney stones 
  • Irregular heartbeat 

If you are concerned you may be experiencing symptoms of Vitamin D toxicity, contact your doctor for further guidance.
