This is because they have more melanin in their skin — a pigment that helps determine skin color. Melanin helps protect the skin from the sun’s UV rays ( 41). In foods and dietary supplements, vitamin D has two main forms, D 2 (ergocalciferol) and D 3 (cholecalciferol), that differ chemically only in their side-chain structures. Both forms are well absorbed in the small intestine. Absorption occurs by simple passive diffusion and by a mechanism that involves intestinal membrane carrier proteins [ 4]. The concurrent presence of fat in the gut enhances vitamin D absorption, but some vitamin D is absorbed even without dietary fat. Neither aging nor obesity alters vitamin D absorption from the gut [ 4]. The factors that affect UV radiation exposure, individual responsiveness, and uncertainties about the amount of sun exposure needed to maintain adequate vitamin D levels make it difficult to provide guidelines on how much sun exposure is required for sufficient vitamin D synthesis [ 15, 28]. Some expert bodies and vitamin D researchers suggest, for example, that approximately 5–30 minutes of sun exposure, particularly between 10 a.m. and 4 p.m., either daily or at least twice a week to the face, arms, hands, and legs without sunscreen usually leads to sufficient vitamin D synthesis [ 13, 15, 28]. Moderate use of commercial tanning beds that emit 2% to 6% UVB radiation is also effective [ 13, 29]. One study found that women deficient in vitamin D experienced no improvement in bone mineral density when they took high dose supplements, even if their blood levels improved ( 40). 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).For this reason, some companies fortify orange juice with vitamin D and other nutrients, such as calcium. One cup (237 mL) of fortified orange juice with breakfast can start your day with up to 100 IU of vitamin D, or 12% of the DV ( 31). vitamin D threshold for the general population relative to a particular condition (such as pregnancy or breastfeeding) and health issues (such as kidney failure or osteoporosis) Children and adults ages 1–70 need approximately 600 IU of vitamin D daily. This can come from a combination of food sources and sunlight. Adults over 70 should aim for at least 800 IU (20 mcg) of vitamin D daily ( 2).

The U.S. Department of Agriculture’s (USDA’s) FoodData Central lists the nutrient content of many foods and provides a comprehensive list of foods containing vitamin D arranged by nutrient content and by food name. However, FoodData Central does not include the amounts of 25(OH)D in foods. Sun exposure 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). Additionally, your bones become more fragile with age. Maintaining adequate blood levels of vitamin D can help preserve bone mass with age and may protect against fractures ( 8, 38).
