 CAUSES of Vitamin D deficiency

  • Sunscreen; sunscreen lotions or products for skin including a sun protection factor that is “SPF” of about 30 can restrict the body from carrying out the processes involved with the vitamin.
  • Skin type; Dark skin, supposedly combined with sunscreen will be harder for the body to absorb the ultraviolet radiation rays from the sun restricting the skin from producing vitamin D.
  • Geographical location; this factor relates to people who live along northern latitudes, highly polluted areas, or people who work night shifts or basically do not leave the house.
  • Covering almost every percentage of your skin with clothing also reduces vitamin D production.

The best ways to obtain vitamins or minerals are through natural sources or dietary supplements. A sufficient amount of sun exposure (if you can) on bare skin can be obtained from 5-10 minutes repeated up to 2-3 times weekly under direct sunlight.
