That’s one reason why maintaining optimal blood levels of vitamin D is critical ( 21, 22). Summary

The RDA for calcium also varies by age. Children ages 4–8 need about 1,000 mg of calcium daily. Children ages 9–18 need approximately 1,300 mg daily. Adults ages 19–50 need about 1,000 mg daily. Over 50, most people need 1,200 mg per day ( 35). Summary Cook, Richard; Everson, Michael (2001-09-20). "L2/01-347: Proposal to add six phonetic characters to the UCS" (PDF).

Recommendations on optimal vitamin D levels vary, but research suggests that levels between 30–60 ng/mL are likely optimal and may help protect against illness and disease ( 4, 5). Blood serum levels considered adequate range from 50–100 nanomoles per liter (nmol/L). Depending on your blood level, you may need more vitamin D.

Aside from medical conditions that can lead to vitamin D deficiency, biological and environmental factors that put someone at an increased risk of vitamin D deficiency include: Even though vitamin D toxicity isn’t common, you may be at risk if you misuse over-the-counter vitamin D supplements, prescription vitamin D supplements, or injections.

Deficient: levels less than 12 nanograms per milliliter (ng/mL), or 30 nanomoles per liter (nmol/L)

Most of the protein in an egg is found in the white, and the fat, vitamins, and minerals are found mostly in the yolk. Older adults are at increased risk of developing vitamin D insufficiency, partly because the skin's ability to synthesize vitamin D declines with age [ 1, 61]. In addition, older adults are likely to spend more time than younger people indoors, and they might have inadequate dietary intakes of the vitamin [ 1]. People with limited sun exposure Most cases of vitamin D toxicity are caused by inappropriate supplement dosing and prescription errors.

The main role of vitamin D in the body is to manage blood levels of calcium and phosphorus. These minerals are important for healthy bones ( 6).

Assessing vitamin D status by measuring serum 25(OH)D concentrations is complicated by the considerable variability of the available assays (the two most common ones involve antibodies or chromatography) used by laboratories that conduct the analyses [ 5, 6]. As a result, a finding can be falsely low or falsely high, depending on the assay used and the laboratory. The international Vitamin D Standardization Program has developed procedures for standardizing the laboratory measurement of 25(OH)D to improve clinical and public health practice [ 5, 7-10]. You can increase your vitamin D levels by getting sun exposure or eating foods rich in vitamin D, including fatty fish, egg yolks, and vitamin D-fortified milk and grains. In some cases of deficiency, a doctor may recommend vitamin D supplements. Which vegetables are high in vitamin D? Optimal serum concentrations of 25(OH)D for bone and general health have not been established because they are likely to vary by stage of life, by race and ethnicity, and with each physiological measure used [ 1, 13, 14]. In addition, although 25(OH)D levels rise in response to increased vitamin D intake, the relationship is nonlinear [ 1]. The amount of increase varies, for example, by baseline serum levels and duration of supplementation. Recommended Intakes
