    What is Vitamin D3?

    A vitamin produced by the body when exposed to ultraviolet light or obtained from dietary sources.

    In the kidney, 25-hydroxy vitamin D changes into an active form of the vitamin. The active form of vitamin D helps control calcium and phosphate levels in the body.

    The 25-hydroxy vitamin D test is the most accurate way to measure how much vitamin D is in your body.

    What are the Symptoms of Vitamin D Deficiency?

    Bone pain and muscle weakness can mean you have a vitamin D deficiency.

    Low blood levels of the vitamin have been associated with the following:

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

    Research suggests that vitamin D could play a role in the prevention and treatment of a number of different conditions, including type1 and type 2 diabetes, hypertension, glucose intolerance, and multiple sclerosis.

    When should you get tested for Vitamin D3?

    • Patients diagnosed with any of the Vitamin D related diseases (cancer, diabetes, hypertension, heart disease, multiple sclerosis, systemic lupus erythematosus, depression, Alzheimer's, Parkinson's, epilepsy, and other others)
    • Patients with osteoporosis or rickets
    • Persistent and nonspecific musculoskeletal pain
    • Signs of depression or lack of energy
    • Patients with gastrointestinal disease and/or who have had a cholecystectomy
    • Elderly individuals
    • Overweight individuals with a BMI >25
    • Infants that are exclusively breastfed or children without a well-balanced diet
    • Individuals taking Vitamin D supplementation greater than 50 mcg (2,000 IUs) per day
    • Individuals with medium to dark complexions or who do not regularly receive 20 minutes of direct sunlight each day

    Can vitamin D deficiency be prevented?

    The major source of vitamin D comes from exposure to sunlight. Get some sun exposure on your skin without sunscreen for 20-30 minutes in the morning or late afternoon. Do use sunscreen during the midday to protect your skin.

    A few foods naturally contain vitamin D, and other foods are fortified with it. The amount found in food is not enough for treating a deficiency and may not be enough to maintain adequate levels unless combined with sun exposure.

    Some facts about Vitamin D

    • While the body can make Vitamin D when the skin is exposed to sunlight, modern life affords inadequate sun exposure to meet our Vitamin D needs.
    • Dark skinned people make less Vitamin D than those with light skin.
    • Aging skin makes 75 percent less Vitamin D than young skin.
    • Use of sunscreens blocks Vitamin D production in the skin.
    • Most people living modern life spend a larger proportion of their time indoors and with most of their skin surface covered by clothing or sunscreen when outdoors.

    What are the dietary sources of Vitamin D3?

    Vitamin D rich foods include cold water fish such as wild salmon, wild cod and sardines and cod liver oil. Egg yolkd, fortified milk, youghurt, orange juice, cheese have Vit D but, it is difficult to regularly eat enough of these foods to build up your Vitamin D stores.

    Be sure to take the correct biologically active form of Vitamin D which is Vitamin D3 (cholecalciferol), not Vitamin D2.

    How is a vitamin D deficiency diagnosed?

    All it takes is a simple blood test to find out if you are deficient in vitamin D,

    The test will measure your 25(OH)D level. The guidelines for serum (blood) 25(OH)D levels are as follows:

    Deficiency : 25(OH)D level is below 12 ng/mL

    Insufficiency : 25(OH)D level is between 12-30 ng/mL

    Sufficiency : 25(OH)D level is between 30-50 ng/mL

    Excessive : 25(OH)D level over 50 ng/mL

    Be sure to get retested to monitor your Vitamin D levels. You should also monitor your blood levels of calcium and phosphorus and parathyroid hormone and you may need to get a bone density test done.
