Vitamin D is essential for life. It is naturally produced in the skin but only becomes biologically active with exposure to sunlight. This sunlight vitamin maintains healthy calcium and phosphorus levels needed for bone strength, supports muscle tone in older adults, and plays an important role in active immune response. Vitamin D3 or cholecalciferol is considered the most efficient form of vitamin D.

  • Vitamin D3 helps with calcium absorption to maintain bone strength until old age. Calcium is the primary nutrient that makes up the bones and teeth. During infancy and adolescent, the body has higher demands for calcium as well as Vitamin D to ensure proper growth and bone development. As calcium absorption decreases with age, the body also needs higher amounts of Vitamin D3 to maintain bone strength. When left untreated, long term vitamin D deficiency can lead to osteoporosis.
  • The benefits of Vitamin D3 for emotional health have long been established by scientific research. Scientists suggest that patients with mild to moderate depression need enough exposure to sunlight to increase their Vitamin D levels for effective management of depression symptoms.
  • Vitamin D exhibits positive effects on the brain and its functions. Hypovitaminosis D or insufficient levels of the sunshine vitamin are prevalent among older adults showing signs of mental deterioration. Based on this, scientists suggest that a good way to prevent age-related memory loss and cognitive impairment is to ensure that the bloodstream contains enough Vitamin D for healthy cognition and mental performance.
  • Cholecalciferol is an essential nutrient for maintaining muscle tone and muscle strength. Vitamin D3 is actively involved in regulating neuromuscular functions and in protein synthesis. According to studies, low levels of Vitamin D3 of 30 nmol/l in the bloodstream lead to muscle weakness and muscle wasting.

Vitamin D is more famous for its name as the sunshine vitamin. This fat soluble vitamin is the only vitamin that can be produced in the body, but it only becomes biologically active with exposure to the sun’s UV rays. Although known collectively as vitamin D, this nutrient is available in different forms including Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Of these two, scientists found that Vitamin D3 is the optimal Vitamin D form that is synthesised in the skin and used by the different organs to maintain proper functioning. Cholecalciferol’s main function is to maintain healthy blood levels of the minerals calcium and phosphorus. It is needed for the absorption of calcium into the bones for mineralisation to maintain its strength and prevent fractures. According to experts, having enough Vitamin D in the body can help prevent the onset of rickets in children and osteomalacia in adults. Rickets occur in children with Vitamin D deficiency characterised by skeletal deformities and delayed growth. Osteomalacia or brittle bone disease in adults causes muscle weakness and brittle bones that are prone to fracture.
