What is the Effect of Vitamin D on Your Body?
Vitamin D can be consumed in the form of food or supplements and exposure to sunlight activates the production of Vitamin D in the skin. This is why people commonly associate getting enough Vitamin D with getting enough sunlight.
“Worldwide, an estimated 1 billion people have inadequate levels of vitamin D in their blood, and deficiencies can be found in all ethnicities and age groups” . Vitamin D deficiency is especially prevalent in any location with a prolonged winter. Given that these problems are commonplace, recognizing the symptoms of a Vitamin D deficiency can let a person know when to consult a medical professional.
For instance, bone pain and muscle weakness are common indicators of Vitamin D deficiency. Since Vitamin D plays an important role in bone and cell growth, Vitamin D deficiency could result in deformed bones, especially in children, pregnant women, and the elderly. Also, a lack of this vitamin can cause unexplained fatigue and difficulty in thinking clearly.
When a person starts experiencing these noticeable symptoms, it usually means that their Vitamin D levels have been depleted for an extended time. It is important that a person consult with a medical professional when they begin experiencing these symptoms because Vitamin D is a vital supplement for the human body.
