Vitamin D Deficiency Common, Sources Include Sunlight and Diet

Summary

Vitamin D deficiency is common and can be linked to limited sun exposure, making sunlight a key natural source of the nutrient. Eggs and salmon can also help supplement vitamin D intake, though they may not meet the full daily requirement.

Key Points
  • Vitamin D is essential for strong bones and calcium use in the body.
  • Many people are deficient, often because they do not spend enough time in sunlight.
  • Sunlight is the most natural source of vitamin D, as the skin produces it under ultraviolet rays.
  • Eggs and salmon fish can also provide vitamin D, but may not fully meet daily needs.
