Vitamin d is a fat-soluble vitamin in a family of compounds that includes vitamins d1, d2, and d3. Your body produces vitamin d naturally when it’s directly exposed to sunlight.
You can also get vitamin d from certain foods and supplements to ensure adequate levels of the vitamin in your blood. Vitamin d has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorus and facilitating normal immune system function (
). Getting enough vitamin d is important for typical growth and development of bones and teeth, as well as improved resistance to certain diseases.

The most serious complications of vitamin d deficiency include: low blood calcium levels (hypocalcemia). Low blood phosphate levels (hypophosphatemia). Rickets (softening of bones during childhood). Osteomalacia (softening of bones in adults). All of these conditions are treatable. While rickets is a treatable and often curable disease, treating it as soon as possible is important. When not treated, milder cases of rickets can result in long-term bone damage that can keep bones from growing properly. Severe cases that aren’t treated can lead to seizures, heart damage and death. The good news is that thanks to vitamin d-fortified infant formula and fortified cow’s milk, rickets is very uncommon in the united states.
Vitamin d is a nutrient you need for good health. It helps your body absorb calcium , one of the main building blocks for strong bones. Together with calcium, vitamin d helps protect you from developing osteoporosis , a disease that thins and weakens the bones and makes them more likely to break. Your body needs vitamin d for other functions too. Your muscles need it to move, and your nerves need it to carry messages between your brain and your body. Your immune system needs vitamin d to fight off invading bacteria and viruses.
3. It might support weight loss
Observational studies indicate that greater body weights are associated with lower vitamin d status, and individuals with obesity frequently have marginal or deficient circulating 25(oh)d levels [ 151 ].
However, clinical trials do not support a cause-and-effect relationship between vitamin d and weight loss. A systematic review and meta-analysis of 15 weight-loss intervention studies that used caloric restriction, exercise, or both, but not necessarily vitamin d supplementation or other treatments, found that people who lost weight had significantly greater increases in serum 25(oh)d levels than those who maintained their weight [ 152 ]. In another study, 10 mcg (400 iu)/day vitamin d and 1,000 mg/day calcium supplementation slightly, but significantly, reduced weight gain amounts in comparison with placebo in postmenopausal women, especially those with a baseline total calcium intake of less than 1,200 mg/day [ 153 ].
Risks of getting too much vitamin D
Symptoms of bone pain and muscle weakness can mean you have a vitamin d deficiency. However, for many people, the symptoms are subtle. Yet, even without symptoms, too little vitamin d can pose health risks. 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. Causes of.
Vitamin d is a fat-soluble vitamin , meaning that it dissolves in fats and oils and can be stored in your body for a long time. Two main dietary forms exist ( ):vitamin d3 (cholecalciferol). Found in some animal foods, like fatty fish and egg yolks. Vitamin d2 (ergocalciferol). Found in some plants, mushrooms, and yeasts. Of the two, d3 (cholecalciferol) seems to be almost twice as effective at increasing blood levels of vitamin d as d2 (ergocalciferol) ( ). Summary vitamin d is a fat-soluble vitamin that your body can store for long periods of time. Of the two main forms — d2 and d3 — the latter is more effective at raising vitamin d levels in your blood.
, work night shifts, or are homebound should aim to consume vitamin d from food sources whenever possible. Breastfeeding: the american academy of pediatrics recommends that all breastfed infants receive (iu) per day of oral vitamin d. Older adults: the skin’s ability to synthesize vitamin d with age. Older adults may also spend more time indoors. Those with conditions that limit fat absorption: vitamin d is fat-soluble, meaning intake is dependent on the gut absorbing dietary fats. Conditions that limit fat absorption can decrease vitamin d intake from the diet. People with obesity : high levels of body fat can limit the body’s ability to absorb vitamin d from the skin.
Vitamin d helps your body absorb calcium from the food you eat. In fact, this is one of its most important roles. However, if your vitamin d intake is excessive, your blood calcium may reach levels that can cause unpleasant and potentially dangerous symptoms. The symptoms of vitamin d toxicity are primarily related to hypercalcemia , which means excessively high blood calcium levels ( digestive distress, such as vomiting, nausea, constipation, and stomach pain fatigue, dizziness, hallucinations, and confusion loss of appetite kidney stones, kidney injury, and even kidney failure high blood pressure and abnormal heart rhythms dehydration poor appetite however, not all people with hypercalcemia experience the exact same symptoms.
