Is Vitamin D3 Original from the Sun?

While vitamin D3 can be obtained through many food sources and supplements, frequent sun exposure is also an effective way to meet your needs. This is because exposure to UV radiation from the sun causes the skin to create vitamin D.

To fulfill your vitamin D requirements, you do not, however, need to sunbathe (although sun protection is still recommended to lower your risk of skin cancer). Dr. White states that 20 minutes or more of sun exposure on the face and arms is usually sufficient to synthesize enough vitamin D in your skin to maintain vitamin D sufficiency, provided the ambient temperature is above 45 degrees Fahrenheit.

How can I tell whether I require more vitamin D?

A vitamin D deficit is defined as not getting enough vitamin D to meet the body’s requirements. Blood tests can be used to diagnose this.

Nonetheless, the U.S. Preventive Services Task Force advises against routinely monitoring adults for vitamin D deficiency if they do not exhibit any symptoms.

Not every person with insufficient vitamin D has symptoms. People who do could take note:

  • Muscle and/or bone pain
  • Muscle weakness
  • History of fractures
  • Muscle twitching
