Vitamin D is a fat-soluble vitamin that is important for bone and muscle health. It is synthesized in the skin upon exposure to sunlight or obtained from dietary sources. The liver and kidneys work to activate vitamin D before it can be used by the body. Vitamin D deficiency can lead to rickets in children and osteomalacia or osteoporosis in adults and is associated with increased risk of various diseases. Treatment of deficiency involves obtaining more vitamin D through diet, supplements, or sunlight exposure.
Vitamin D deficiency can lead to rickets in children and osteomalacia in adults. It is caused by insufficient vitamin D intake from food or sun exposure, impaired vitamin D absorption or metabolism. Symptoms include weakened, soft bones and muscle weakness. Diagnosis involves measuring blood levels of vitamin D and calcium. Treatment consists of high dose vitamin D supplementation.
This document discusses vitamin D, its natural sources, deficiency, and importance. It notes that vitamin D is a fat-soluble vitamin essential for bone and calcium health. While sunshine is the main natural source, few foods contain significant amounts. Vitamin D deficiency is very common worldwide and increases risk of bone abnormalities and other diseases. Deficiency can result from inadequate sun exposure, skin pigmentation, obesity, lack of nutritional intake, and other factors. At-risk groups include breastfed infants, older adults, those with limited sun exposure or dark skin, and the obese. Blood tests can identify deficiency which is treated through dietary sources and supplements.
Vitamin D deficiency is very common globally, including in Saudi Arabia where prevalence is around 90-95%. Vitamin D is important for bone and skeletal health and development during childhood, as it regulates calcium and phosphorus balance and bone mineralization. Beyond skeletal benefits, vitamin D has roles in reducing infection risk, autoimmune disease, asthma, COPD and cancer. Deficiency is diagnosed through blood tests measuring vitamin D levels, with normal being 30-100 ng/ml. Deficiency can cause rickets or osteomalacia and is often due to lack of sun exposure or intake of vitamin D sources like fortified foods. Prevention involves sun exposure, intake of vitamin D foods or supplements. Treatment requires high dose vitamin D
Vitamin D plays an important role in bone and mineral metabolism and is also involved in preventing many chronic diseases. It is synthesized in the skin upon exposure to sunlight and is also obtained through dietary sources. Most cells in the body have receptors for vitamin D. Deficiency is linked to increased risk of diseases such as cancer, cardiovascular disease, diabetes and multiple sclerosis. Adequate vitamin D levels can be maintained through sensible sun exposure, dietary sources like fatty fish, and supplementation.
Vitamin D is a fat-soluble vitamin that is obtained through sunlight exposure and dietary sources like fatty fish and fortified foods. It plays an important role in bone and immune health by aiding in calcium absorption and bone mineralization. Testing for vitamin D levels has increased in recent years due to research linking vitamin D deficiency to diseases like cancer, heart disease, diabetes and depression. While vitamin D shows promise for many health benefits, more research is still needed to fully understand its therapeutic potential.
Vitamin D is a fat-soluble vitamin known as the "sunshine vitamin" because the skin produces it when exposed to sunlight. It plays a crucial role in maintaining strong bones by aiding in the absorption of calcium and phosphorus. Vitamin D also supports the immune system, cell growth, and brain health. Dietary sources include fatty fish, egg yolks, and fortified foods, and supplements are available when sun exposure is limited. Both deficiency and excess can have health implications, so it's important to maintain an appropriate balance.

Vitamins are organic substances that are essential for carrying out normal biochemical processes and physiological functions. They are divided into fat-soluble vitamins (A, D, E, K) and water-soluble vitamins. Fat-soluble vitamins are stored in the liver and excessive intake can lead to toxicity, while water-soluble vitamins are excreted and toxicity does not occur. Vitamins must be activated in the body and deficiencies can cause specific syndromes, while adequate intake through a balanced diet meets daily requirements.
Vitamins are organic compounds that occur naturally in small amounts in foods. They are required for normal growth, maintenance, and reproduction. There are two types of vitamins - fat-soluble (A, D, E, K) and water-soluble (C, B vitamins). Vitamin deficiencies can occur due to reduced intake, impaired absorption, metabolism or increased losses. The major vitamins, their functions, dietary sources, and deficiency diseases are described.
