    Symptoms and Health Risks of Vitamin D Deficiency

    Symptoms of bone pain and muscle weakness can mean you have a Vitamin D deficiency. Yet even without symptoms, too little Vitamin D can pose health risks. Low blood levels of Vitamin D have been associated with the following:

    • Increased risk of death from cardiovascular disease
    • Cognitive impairment in older adults
    • Severe asthma in children
    • Cancer

    Research also suggests that Vitamin D could play a role in the prevention and treatment of a number of different conditions, including type 1 and type 2 diabetes, hypertension, glucose intolerance, and multiple sclerosis.

    Causes of Vitamin D Deficiency

    Vitamin D deficiency can occur for a number of reasons:

    • You don’t consume the recommended levels of the Vitamin over time.
    • Your exposure to sunlight is limited.
    • You have dark skin.
    • Your kidneys cannot convert Vitamin D to its active form.
    • Your digestive tract cannot adequately absorb Vitamin D.
    • You are obese.
