OsteomalaciaVitamin D / UseOsteomalacia is a disease characterized by the softening of the bones caused by impaired bone metabolism primarily due to inadequate levels of available phosphate, calcium, and vitamin D, or because of resorption of calcium. The impairment of bone metabolism causes inadequate bone mineralization. Wikipedia
The most important steps are to fit vitamin D into your routine and take it consistently to ensure maximum effectiveness. Try taking it alongside breakfast or with a bedtime snack — as long as it doesn't interfere with your sleep.
Some people may need a higher dose, however, including those with a bone health disorder and those with a condition that interferes with the absorption of vitamin D or calcium, says Dr. Manson. Unless your doctor recommends it, avoid taking more than 4,000 IU per day, which is considered the safe upper limit.
Symptoms of vitamin D deficiency can include muscle weakness, pain, fatigue and depression. To get enough D, look to certain foods, supplements, and carefully planned sunlight....Signs and symptoms might include:Fatigue.Bone pain.Muscle weakness, muscle aches, or muscle cramps.Mood changes, like depression.
Vitamin D deficiency is most commonly caused by a lack of exposure to sunlight. Some disorders can also cause the deficiency. The most common cause is lack of exposure to sunlight, usually when the diet is deficient in vitamin D, but certain disorders can also cause the deficiency.
Foods high in vitamin D include fish, mushrooms exposed to sunlight, fortified milk, fortified milk substitutes, fortified tofu, fortified yogurt, fortified breakfast cereals, fortified orange juice, pork chops, and eggs.

Results: Vitamin D receptors and the enzymes that control their activation and degradation are expressed in several areas of the brain involved in sleep regulation. Vitamin D is also involved in the pathways of production of Melatonin, the hormone involved in the regulation of human circadian rhythms and sleep.

Use in writing systems. The letter D, standing for "Deutschland" ( German for " Germany "), on a boundary stone at the border between Austria and Germany. In most languages that use the Latin alphabet, and in the International Phonetic Alphabet, ⟨d⟩ generally represents the voiced alveolar or voiced dental plosive /d/.
The minuscule (lower-case) form of 'd' consists of a loop and a tall vertical stroke. It developed by gradual variations on the majuscule (capital) form. In handwriting, it was common to start the arc to the left of the vertical stroke, resulting in a serif at the top of the arc.
In British Sign Language (BSL), the letter 'd' is indicated by signing with the right hand held with the index and thumb extended and slightly curved, and the tip of the thumb and finger held against the extended index of the left hand.
Other definitions for 'd (6 of 12) Symbol. the fourth in order or in a series. (sometimes lowercase) (in some grading systems) a grade or mark, as in school or college, indicating the quality of a student's work as poor or barely passing.

Depression. Vitamin D is involved in various brain processes, and vitamin D receptors are present on neurons and glia in areas of the brain thought to be involved in the pathophysiology of depression [ 128 ].
Vitamin D obtained from sun exposure, foods, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first hydroxylation, which occurs in the liver, converts vitamin D to 25-hydroxyvitamin D [25 (OH)D], also known as “calcidiol.”.
Ready-to-eat breakfast cereals often contain added vitamin D, as do some brands of orange juice, yogurt, margarine, and other food products. The United States mandates the fortification of infant formula with 1–2.5 mcg/100 kcal (40–100 IU) vitamin D; 1–2 mcg/100 kcal (40–80 IU) is the required amount in Canada [ 1 ].
An animal’s diet affects the amount of vitamin D in its tissues. Beef liver, cheese, and egg yolks have small amounts of vitamin D, primarily in the form of vitamin D 3 and its metabolite 25 (OH)D 3. Mushrooms provide variable amounts of vitamin D 2 [ 17 ].
Vitamin D is also needed for the normal development and growth of muscle fibers. In addition, inadequate vitamin D levels can adversely affect muscle strength and lead to muscle weakness and pain (myopathy) [ 1 ].
DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. These values, which vary by age and sex, include:
Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal bone mineralization and to prevent hypocalcemic tetany (involuntary contraction of muscles, leading to cramps and spasms).
D allows writing large code fragments without redundantly specifying types, like dynamic languages do. On the other hand, static inference deduces types and other code properties, giving the best of both the static and the dynamic worlds. Show example
Refer to the language specification and the documentation of Phobos, D's standard library. The DMD manual tells you how to use the compiler. Read various articles to deepen your understanding.
D, or d, is the fourth letter of the modern English alphabet and the ISO basic Latin alphabet. Its name in English is dee , plural dees.
The minuscule (lower-case) form of 'd' consists of a lower-story left bowl and a stem ascender. It most likely developed by gradual variations on the majuscule (capital) form 'D', and today now composed as a stem with a full lobe to the right. In handwriting, it was common to start the arc to the left of the vertical stroke, resulting in a serif at the top of the arc. This serif was extended while the rest of the letter was reduced, resulting in an angled stroke and loop. The angled stroke slow…
