Vitamin D deficiency in children can cause rickets , which leads to a severely bowlegged appearance due to the softening of the bones. Similarly, in adults, vitamin D deficiency manifests as osteomalacia , or softening of the bones. Osteomalacia results in poor bone density and muscular weakness. A vitamin D deficiency can also present as osteoporosis , for which over 53 million people in the United States either seek treatment or face an increased risk.
A review of existing research suggested that some studies had found that vitamin D had a protective effect against the influenza virus. However, the authors also looked at other studies where vitamin D did not have this effect on flu and flu risk. Further research is, therefore, necessary to confirm the protective effect of vitamin D on the flu.
Vitamin D deficiency has links to high blood pressure in children. One study found a possible connection between low vitamin D levels and stiffness in the arterial walls of children.
An example of this is children who live closer to the equator and have lower rates of admission to hospital for allergies plus fewer prescriptions of epinephrine autoinjectors. They are also less likely to have a peanut allergy. Eggs are a common early source of vitamin D. The children who started eating eggs after 6 months were more likely to develop food allergies than children who started between 4—6 months of age.
Furthermore, vitamin D may enhance the anti-inflammatory effects of glucocorticoids. This benefit makes it potentially useful as a supportive therapy for people with steroid resistant asthma. A review suggests that pregnant women who are deficient in vitamin D may have a greater risk of developing preeclampsia and giving birth preterm.
Doctors also associate poor vitamin D status with gestational diabetes and bacterial vaginosis in pregnant women. Vitamin D is a natural defense against this process as it partially shuts down the cytokine release caused by the presence of the COVID virus.
Unfortunately, many Americans are vitamin D deficient, and supplementation was necessary to achieve therapeutic levels. Various uses of vitamin D supplementation are listed in the table below. You should always seek medical advice before beginning vitamin D supplementation. Sign up for Vitamin D price alerts and find out when the price changes! Get Price Alerts. Vitamin D2 and D3 are absorbed into the bloodstream where they are metabolized by the liver into hydroxyvitamin D2 and hydroxyvitamin D3, otherwise collectively known as 25D or calcifediol.
Calcifediol is commonly referred to as the active form of vitamin D. When your doctor orders lab tests to check your vitamin D levels, they are measuring your calcifediol 25D levels. There have been several studies comparing whether supplementation with vitamin D2 or D3 produces a higher blood level of calcifediol. A study published by the National Institutes of Health was conducted in elderly, post-menopausal women who had been identified as vitamin D deficient.
It compared the effects of receiving a single high dose of vitamin D2 or vitamin D3 on calcifediol levels. The study concluded that vitamin D3 produced about twice the amount of circulating calcifediol in this patient population versus that of vitamin D2. In a separate clinical trial comparing a week regimen of twice weekly 50, IU dosing of both vitamin D2 and vitamin D3 in demographically matched groups, vitamin D3 was also found to be superior in producing higher levels of 25D, or calcifediol.
In terms of the lab tests which measure vitamin D levels, your doctor may evaluate total 25D or free 25D, or both. Sign up for Vitamin D3 price alerts and find out when the price changes! Vitamin D2 in prescription form is commonly covered by most commercial and Medicare insurance plans. The over-the-counter formulations are typically not covered by commercial or Medicare insurance plans. The price can vary greatly depending on dosage. Vitamin D3 is over-the-counter, and therefore is typically not covered by insurance plans.
The price varies depending on dose. There are no common side effects to therapy with either vitamin D2 or D3. Side effects related to vitamin D are the result of hypervitaminosis D, an extremely rare condition that occurs when you intake too much vitamin D. This is sometimes seen in patients who take megadoses of vitamin D, leading to vitamin D toxicity.
The result is a build up of dangerously high levels of calcium in the blood which can lead to nausea, vomiting, constipation, and frequent urination. If left untreated, irreversible renal failure can occur along with calcification of organs and soft tissues. The following table lists side effects related to hypervitaminosis D, not normal vitamin D supplementation.
