For vitamin D deficiency: 50,000 IU per week for 6-12 weeks has been used. However, some patients require higher doses for longer periods of time to maintain optimal blood levels of vitamin D. For preventing osteoporosis: 400-1000 IU/day of vitamin D in a form known as cholecalciferol has been used in older adults.

1 Microgram (mcg) is equal to 0.001 milligram (mg). For example, to find out how many milligrams there are in 100 micrograms, multiply 100 by 0.001, that makes 0.1 mg in 100 mcg.

The term “mg” stands for the measurement of “milligrams,” while “mcg” stands for “micrograms.” Both units are used to measure an object’s mass and to indicate an object’s weight. With reference to other units of measurement, a mcg is equal to . 001 mg.

From IU to mg: IU * 0.67 = mg. From mg to IU: mg * 1.5 = IU see less In the metric system, 1000 milligrams (mg) is a unit of mass equal to 1 gram and 1000 micrograms (mcg) is equal to 1 milligram (mg). An IU (International Unit) is a unit of measurement for vitamins and other specific biologically active substances.

Simply adding an over-the-counter vitamin D supplement can make improvements in just three to four months’ time. Vitamin D with a strength of 2000 international units daily is the recommended dose for most adults.

Vitamin D is a fat-soluble vitamin, meaning that it does not dissolve in water and is absorbed best in your bloodstream when paired with high-fat foods. For this reason, it’s recommended to take vitamin D supplements with a meal to enhance absorption.

Steroid medications such as prednisone can interfere with vitamin D metabolism. If you take steroid drugs regularly, discuss vitamin D with your doctor. The weight loss drug orlistat — brand names include Xenical and Alli — may cut absorption of vitamin D.

Midday, especially during summer, is the best time to get sunlight. At noon, the sun is at its highest point, and its UVB rays are most intense. That means you need less time in the sun to make sufficient vitamin D ( 5 ). Many studies also show that the body is most efficient at making vitamin D at noon ( 6 , 7 ).

Symptoms of vitamin D deficiency can include muscle weakness, pain, fatigue and depression.

If you lack in vitamin D, then a lot of other micronutrients and minerals don’t get absorbed in your body. And due to this you feel fatigued”, explains Ms Srivastava.

When your body runs low on vitamin D, it affects your immunity, making you more prone to ailments like cold and flu, fever, allergies, asthma, and eczema.

The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D blood test. A level of 20 nanograms/milliliter to 50 ng/mL is considered adequate for healthy people. A level less than 12 ng/mL indicates vitamin D deficiency.

Low levels of vitamin D are associated with schizophrenia, depression and anxiety in the general population. Yet, little is known about how vitamin D levels in children with 22q11. 2DS could mediate risk of psychosis in adulthood.

Studies have shown a link between vitamin D deficiency and depression. Researchers behind a 2013 meta-analysis noticed that study participants with depression also had low vitamin D levels. The same analysis found that, statistically, people with low vitamin D were at a much greater risk of depression.

Low vitamin D levels have been linked to increased levels of anxiety, depression, and stress to such an extent that we recommend each and every patient experiencing any of these situations have their vitamin D levels evaluated.
