VITAMIN D
What is vitamin D?
Vitamin D is a fat-soluble vitamin that plays a crucial role in maintaining the health of bones, teeth, and muscles. It exists in two forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).
Vitamin D is unique as it can be synthesised by the body when the skin is exposed to sunlight, and it can also be obtained through dietary sources or supplements. It aids in the absorption of calcium and phosphorus, promotes proper immune system function, and helps regulate mood and sleep patterns.
Vitamin D deficiency can lead to various health issues, including weakened bones (osteoporosis) and increased susceptibility to infections.
Studies have shown that vitamin D has important effects on the immune system and can play a role in managing inflammatory diseases. The active form of vitamin D has been found to have anti-inflammatory properties, which can be beneficial in conditions associated with immune dysregulation and inflammation.
Supplementing with vitamin D is believed to have positive effects on immune function, particularly in individuals with autoimmune disorders or chronic inflammatory conditions. Adequate levels of vitamin D may help regulate the immune response and reduce the risk of infection and inflammation-related diseases.
Vitamins or minerals that enhance the absorption of vitamin D include:
- Calcium: Calcium is important for bone health and can enhance vitamin D absorption. Vitamin D helps the body absorb calcium from the digestive tract, and calcium, in turn, supports the function of vitamin D in maintaining bone health.
- Magnesium: Magnesium is involved in the conversion of vitamin D into its active form in the body. Adequate magnesium levels can help optimise the effectiveness of vitamin D.
- Vitamin K: Vitamin K plays a role in bone metabolism and may interact with vitamin D to support bone health. Some studies suggest that vitamin K2, in particular, may have a synergistic effect with vitamin D in maintaining bone density.
