Vitamin-D (Functions, RDA, Deficiency and Health Issues

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.<br>https://www.icfitnessclub.com/

  3. www.icfitnessclub.com Vitamin D (Introduction & Function) Vitamin D is a fat-soluble vitamin that plays a crucial role in several vital functions within the human body. There are two primary forms of vitamin D: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is synthesized in the skin when exposed to ultraviolet B (UVB) radiation from sunlight, while vitamin D2 is obtained from certain plant-based foods or supplements.

  4. FUNCTIONS OF VITAMIN D • Calcium and Phosphorus Absorption: One of the main functions of vitamin D is to enhance the absorption of calcium and phosphorus from the intestine. This process is essential for maintaining proper bone health and mineralization, preventing conditions like rickets in children and osteomalacia in adults. • Bone Health: Vitamin D helps regulate the levels of calcium in the blood by promoting its absorption from the gut and reabsorption from the kidneys. It also facilitates the deposition of calcium in bones, making them stronger and less prone to fractures. • Cardiovascular Health: Emerging research indicates that vitamin D may have a positive impact on cardiovascular health by helping to regulate blood pressure, reduce inflammation, and improve overall heart function.

  5. RDA(recommended Dietary Allowance) OF VITAMIN D The Recommended Dietary Allowance for adults 19 years and older is 600 IU (15 mcg) daily for men and women, and for adults >70 years it is 800 IU (20 mcg) daily.

  6. Deficiency of Vitamin-D & Health Issues • Osteoporosis and Osteomalacia: Weak bones and fractures. • Rickets: Soft and weak bones in children. • Muscle Weakness and Pain: Weak muscles and increased risk of falls. • Immune System Impairment: Increased susceptibility to infections. • Cardiovascular Problems: Higher risk of heart diseases. • Mood Disorders: Increased risk of depression and anxiety. • Autoimmune Diseases: Linked to conditions like multiple sclerosis and rheumatoid arthritis.
