Vitamin D helps your body absorb calcium from the food you eat. In fact, this is one of its most important roles.

Fortunately, some food products that don’t naturally contain vitamin D are fortified with this nutrient. Cow’s milk In contrast to the openness of Luffy and other "D"-bearers, there are some "D." families who seem to know its meaning and try to keep it secret from the public, such as Trafalgar Law's. [6] First, the liver converts dietary vitamin D into the storage form of vitamin D. This is the form that is measured in blood tests. Later, the storage form is converted by the kidneys to the active form of vitamin D that’s used by the body ( 1). While there’s no single cause for deficiency, your overall risk may be higher as a result of certain underlying conditions or lifestyle factors. Some of the most common risk factors for vitamin D deficiency are ( 5):If you receive a diagnosis of vitamin D deficiency, a healthcare professional will likely recommend that you take vitamin D supplements. If you have a severe deficiency, they may instead recommend high dose vitamin D tablets or liquids. Said to have been an extremely vicious and violent man, thus the only "D." bearer to be inherently "evil".

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].

However, several older studies have found that a blood level of 30 ng/mL (75 nmol/L) could be even better for preventing fractures, falls, and certain cancers ( 23, 24, 25). Many commercially grown mushrooms are grown in the dark and contain very little D2. Some mushrooms are treated with ultraviolet (UV) light to boost their vitamin D content. One cup of cremini mushrooms exposed to UV light contains 1,110 IU of vitamin D, which is 139% of the DV ( 23, 24). Summary Many people don’t get enough vitamin D. It’s hard to know how many people are deficient because experts have not reached an agreement about what target levels should be ( 1).
