According to MedlinePlus, vitamin D helps the body absorb calcium, a mineral needed for normal bone formation. It is one of two main supplement forms of vitamin D, listed as D2 (ergocalciferol) alongside D3 (cholecalciferol). Adequate vitamin D is associated with maintaining bone health, while inadequate intake is linked to weakened bones. The source frames vitamin D as a nutrient obtained from certain foods, fortified foods, and supplements rather than as a remedy for specific conditions. Individual needs vary, so the source provides general intake reference values rather than personalized guidance. — per NIH MedlinePlus; not medical advice.
MedlinePlus states there are two forms of vitamin D used in supplements: D2 (ergocalciferol) and D3 (cholecalciferol).
MedlinePlus notes that mushrooms, especially those exposed to ultraviolet light, are a food source of vitamin D, along with fatty fish (tuna, salmon, mackerel), beef liver, cheese, and egg yolks. It adds that vitamin D is also added to many fortified foods, including most milk in the United States (fortified with 400 IU per quart), breakfast cereals, soy beverages, orange juice, yogurt, and margarine.
Per MedlinePlus, inadequate vitamin D can be associated with weakened bones, described as osteomalacia and osteoporosis in adults or rickets in children.
MedlinePlus reports that the safe upper limit of vitamin D for adults is 4,000 IU/day (100 mcg/day), while listing typical needs of 600 IU (15 mcg) per day for adults aged 19-70 and 800 IU (20 mcg) per day for those over 70. It states that consuming too much vitamin D may lead to high levels of calcium in the blood, which can be associated with calcium deposits in organs, kidney damage, kidney stones, nausea, and constipation. These are general reference values, and the source does not substitute for individualized advice. — per NIH MedlinePlus; not medical advice.
