Vitamin D-The Sunshine Vitamin

Vitamin D is a water-soluble vitamin, which means it needs water to dissolve and to be used by our body. It is produced endogenously when ultraviolet rays from the sun hit the skin.

Vitamin D is called the Sunshine Vitamin. A cholesterol compound found in the skin, converts to a precursor of vitamin D. This is just one more reason why we NEED cholesterol. One full body UV exposure causing a slight pinkness in the skin is equivalent to an oral intake of 10,000–25,000 IU of vitamin D3.

  • Sunscreens with vitamin A. Government studies show spreading vitamin A on your skin may cause tumors and lesions to develop sooner with creams laced with vitamin A, aka as retinyl palmitate or retinol.

  • Sunscreens with oxybenzone, a synthetic estrogen, which penetrates the skin and can disrupt the hormone system.

Look for sunscreens with zinc oxide, 3% avobenzone or Mexoryl SX. They protect the skin from UVA radiation. Go to to see how your sunscreen ranks.
