Vitamin D is one of the most important vitamins needed by our bodies to maintain optimum health. It facilitates calcium absorption in our stomachs, modulates cell growth, regulates our mood, and much more. When we are deficient in vitamin D, we often begin to suffer from bone pain, muscle weakness, cardiovascular conditions, low moods, and countless other health conditions.
Since human skin cells are able to manufacture vitamin D using certain wavelengths of ultraviolet B light, sunlight will always remain the greatest source of this essential vitamin. In fact, experts estimate that our bodies can create between 10,000 and 20,000 international units of vitamin D after only 30 minutes of full-body sunbathing, which greatly exceeds an adult’s recommended daily intake (RDI) of 600 international units.
However, those of us who live in low sunlight areas will have to obtain much of our vitamin D from food alone (unless we’re willing to take a synthetic supplement). Fortunately, a small number of natural foods do contain respectable amounts of the all-important “sunshine vitamin.”
