These include inflammatory bowel disease (Crohn’s disease and ulcerative colitis), liver disease, and people who have had bariatric surgery ( 14, 45).

These included nausea, vomiting, muscle weakness, and kidney injury. Her blood calcium levels were 3.23 mmol/L (12.9 mg/dL) ( 12). Though both vitamin D2 and vitamin D3 can increase blood levels of vitamin D, some research suggests that vitamin D3 is more effective ( 7). In contrast to 25(OH)D, circulating 1,25(OH)2D is generally not a good indicator of vitamin D status because it has a short half-life measured in hours, and serum levels are tightly regulated by parathyroid hormone, calcium, and phosphate [ 1]. Levels of 1,25(OH)2D do not typically decrease until vitamin D deficiency is severe [ 2]. Serum concentrations of 25(OH)D and healthBecause sunlight is a natural source of vitamin D, your doctor may also recommend going outdoors more often. However, given the negative effects of excess ultraviolet exposure, it’s important to take precautions by limiting your total time in the sun and applying sunscreen. summary One study showed that the vitamin D content of salmon caught in the Baltic sea ranged from 556–924 IU of vitamin D per one 3.5-ounce (100-gram) serving, providing 70–111% of the DV ( 5). Skin color: It’s more difficult for dark-colored skin to make vitamin D from sunlight than light-colored skin, so people with darker skin are at a higher risk for vitamin D deficiency. Vitamin D deficiency is typically defined as having blood levels below 20 ng/mL, while levels from 21–29 ng/mL are considered insufficient ( 60). Vitamin D deficiency has been linked to depression, especially in older adults — although some study results are conflicting ( 22, 23, 24).

The vitamin D receptor is present in nerve cells called nociceptors, which sense pain. This vitamin may also be involved in your body’s pain signaling pathways, which may play a role in chronic pain ( 53).An FNB committee established RDAs for vitamin D to indicate daily intakes sufficient to maintain bone health and normal calcium metabolism in healthy people. RDAs for vitamin D are listed in both micrograms (mcg) and International Units (IU); 1 mcg vitamin D is equal to 40 IU (Table 2). Even though sunlight is a major source of vitamin D for some people, the FNB based the vitamin D RDAs on the assumption that people receive minimal sun exposure [ 1]. For infants, the FNB committee developed AIs based on the amount of vitamin D that maintains serum 25(OH)D levels above 20 ng/mL (50 nmol/L) and supports bone development. Table 2: Recommended Dietary Allowances (RDAs) for Vitamin D [ 1] Age If you’ve had weight-loss surgery, it’s important to see your healthcare provider regularly so they can monitor your vitamin D levels and other nutrient levels. You’ll likely need to take vitamin D supplements and other supplements throughout your life. Medications that can cause vitamin D deficiency For starters, your skin gets thinner as you grow older. This makes it harder for your skin to make vitamin D3 when it is exposed to sunlight ( 37). Often switched with the letter r on non-initial positions in early texts which may indicate ancient pronunciation of words.

Meanwhile, the same amount of UV-exposed raw white mushrooms contains nearly 92% of the DV ( 35, 36). These include older people, those with darker skin, people who live far from the equator and those with certain medical conditions.
