Vitamin D deficiency is more common than you might think.
Vitamin D deficiency can cause depressive mood, low energy and decreased immune response. Vitamin D, often called the sunshine vitamin, is an important micronutrient that your body produces when you expose your skin to sunlight.
Vitamin D deficiency is a common condition that affects over 25% of Americans, and 18% are considered extremely low in vitamin D.
Vitamin D is found in cells throughout the body and is needed for maintenance of strong bones, immune system function, neuromuscular function, improving mood regulation, protecting the brain against toxic chemicals, and potentially reducing pain.
