How to treat vitamin d deficiency

Cholecalciferol (vitamin D 3) supplementation should be used for vitamin D repletion because it may be more effective in preventing nonvertebral fractures. (Strength of Recommendation [SOR]: B, based on subgroup analysis of randomized controlled trials [RCTs].) Cholecalciferol produces higher serum 25-hydroxyvitamin D levels than ergocalciferol (vitamin D 2). Vitamin D therapy may be given daily or weekly with equal effectiveness; the dosage depends on the degree of deficiency. (SOR: C, based on an RCT and cohort study.) The cumulative dosage is more important than dosing frequency, so the choice of daily, weekly, or monthly dosing can be based on patient preference. (SOR: C, based on an RCT.) Vitamin D levels should be rechecked after three months to ensure adequate response. (SOR: C, based on an observational study.) In the same RCT of 32 vitamin D–deficient participants who received 300,000 IU of cholecalciferol, oral administration increased 25-hydroxyvitamin D levels by 47.8 ± 7.3 ng per mL (119.31 ± 18.22 nmol per L) compared with 15.9 ± 11.3 ng per mL (39.69 ± 28.20 nmol per L) with intramuscular cholecalciferol administration ( P< .001). A review of two RCTs on vitamin D repletion concluded that daily oral dosages of 1,160 to 2,200 IU (depending on the degree of deficiency) are needed to reach and maintain serum levels greater than 30 ng per mL ( , ). A prospective cohort study of 208 vitamin D–deficient patients 18 to 88 years of age found that, based on body weig...

You may be able to get more vitamin D by increasing your time in the sunlight, taking a supplement, and eating certain foods, including mushrooms. Vitamin D is an essential nutrient that your body needs for many vital processes, including building and maintaining strong bones. Low vitamin D intake is considered a major public health concern across the globe. In fact, vitamin D deficiency is estimated to affect 13% of the world’s population ( Here are 7 effective ways to increase your vitamin D levels. Vitamin D is a Emerging research suggests that vitamin D may help prevent a variety of illnesses, such as depression, diabetes, cancer, and heart disease. However, vitamin D’s relationship to these conditions is still poorly understood ( How much do you need? There is significant debate within the scientific community about how much vitamin D your body needs. While the U.S. National Academy of Medicine considers 600–800 IU of daily vitamin D to be sufficient for the majority of the population, the U.S. Endocrine Society recommends 1,500–2,000 IU per day ( The Reference Daily Intake (RDI) is currently set at 600-800 IU of vitamin D for adults, based on the U.S. National Academy of Medicine’s recommendations ( The optimal blood level of vitamin D is not concretely established but likely falls between 20 and 50 ng/ml ( The U.S. National Academy of Medicine further suggests that a daily intake up to 4,000 IU of vitamin D per day is safe for most people, although much higher doses...

Generally, it takes a few weeks of taking daily vitamin D supplements for vitamin D levels in the body to rise. Each 1,000 IU of vitamin D3 taken daily is expected to raise blood levels of 25(OH)D by 10 ng/ml after a few weeks. But it may take months to resolve symptoms of severe vitamin D deficiency such as rickets in children. It depends on how low your vitamin D levels were in the first place and some individual factors. Obesity, polluted environments, and malabsorption syndromes (such as Crohn’s disease) are just some factors that can increase the time it takes for vitamin D supplements to increase vitamin D levels. Research has found that vitamin D insufficiency resolved with 12 weeks of weekly high-dose vitamin D. How much vitamin D should I take daily? Guidelines in the United States and internationally vary as to how much vitamin D you should ingest daily to maintain good health or resolve a deficiency. The recommended dietary allowance for Vitamin D recommended by the Institute of Medicine, Food and Nutrition Board depends on age and is as follows: • 0-12 months: 400IU (10mcg) • 1 to 70 years: 600IU (15mcg) • Over 70 years: 800IU (20mcg). People who are vitamin D deficient will need more than this. Dosages vary depending on the level of deficiency, but one source recommended 2000 IU daily for a person with vitamin D insufficiency with higher dosages recommended for those diagnosed vitamin D deficient. Talk to your doctor about this. What does it mean to be vitamin...

Vitamin D deficiency occurs when the body doesn’t get enough vitamin D from sunlight or diet. Vitamin D deficiency can cause loss of bone density, osteoporosis, and broken bones. Vitamin D is sometimes called the sunshine vitamin because your body makes it from cholesterol when your skin is exposed to sunlight ( This vitamin has recently garnered a lot of attention for its role in immune health, specifically regarding COVID-19. It’s also critical to bone health and many important functions throughout your body ( Most adults should get 1,500–2,000 international units (IU) of vitamin D daily. While certain foods, such as fatty fish and fortified dairy products, do contain this vitamin, it’s difficult to get enough through your diet alone ( It’s no surprise, then, that vitamin D deficiency is one of the most common nutritional deficiencies worldwide ( This article explores vitamin D and why it’s important to get enough of it.
