One study in adults found a possible link between low vitamin D status and both belly fat and increased weight, although these effects were more pronounced in men ( 56). Your vitamin D needs depend on a variety of factors. These include your age, skin color, current blood vitamin D levels, location, sun exposure, and more ( 17). The best way to prevent vitamin D deficiency is to ensure you’re getting enough vitamin D in your diet and/or through sun exposure. But be careful about being in the sun for too long without sunscreen. Excessive sun exposure puts you at an increased risk for skin cancer. The following includes common questions about vitamin D food sources. How can I increase my vitamin D fast? Recommended Dietary Allowance (RDA): Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals; often used to plan nutritionally adequate diets for individuals

This is a fact sheet intended for health professionals. For a general overview of Vitamin D, see our consumer fact sheet on Vitamin D. A low blood level of vitamin D is linked to a greater risk of fractures and falls, heart disease, multiple sclerosis, several cancers, and even death ( 8, 9, 10, 11, 12, 13). summary

Homebound individuals; people who wear long robes, dresses, or head coverings for religious reasons; and people with occupations that limit sun exposure are among the groups that are unlikely to obtain adequate amounts of vitamin D from sunlight [ 62]. The use of sunscreen also limits vitamin D synthesis from sunlight. However, because the extent and frequency of sunscreen use are unknown, the role that sunscreen may play in reducing vitamin D synthesis is unclear [ 1]. People with dark skin

Vitamin D (also referred to as calciferol) is a fat-soluble vitamin that is naturally present in a few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet (UV) rays from sunlight strike the skin and trigger vitamin D synthesis. Nonetheless, adequate vitamin D intake may be a good strategy to protect your bone mass and reduce fracture risk ( 39). Hair lossAdequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA Miller, Kirk; Rees, Neil (2021-07-16).

This is important because taking vitamin D and calcium at the same time helps your body maximize absorption ( 34). In a 2021 case report, a 64-year-old man accidentally took 200,000 IU of vitamin D per day because he misunderstood medication instructions. He showed altered mental status and other serious symptoms related to hypercalcemia. If you live far from the equator, then you need to get more vitamin D from your diet and supplements. According to one older review, many experts agree that at least 1,000 IU (25 mcg) of vitamin D3 daily is needed in situations where there is no exposure to sunlight ( 44).

According to the United States Department of Agriculture (USDA) Food Composition Database, one 3.5-ounce (100-gram) serving of farmed Atlantic salmon contains 526 IU of vitamin D, or 66% of the DV ( 4).The Environmental Defense Fund (EDF) recommends only a single 3.5-ounce (100-gram) serving of light tuna per week. If you’re concerned about mercury consumption, talk with a doctor about the appropriate amount of tuna to eat weekly ( 16). Summary One Piece Manga and Anime — Vol. 77 Chapter 764 (p. 7-8) and Episode 703, Rosinante mentions the "family of D.". 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].
