Metagenics Vitamin D3 1000IU helps to maintain a healthy immune function, supports strong, healthy bones & muscle strength.

 Vitamin D has been shown to play an important role in supporting the immune system. Vitamin D enhances the response to both bacterial and viral pathogens, by promoting differentiation and activity of our white blood cells called macrophages. Vitamin D has also been shown to influence the cytokine production of immune cells, helping to control inflammation in the body.

Vitamin D helps calcium absorption by improving the efficiency of intestinal calcium absorption and also helps with  parathyroid hormone regulation of serum calcium levels. In a low vitamin D state, the intestine absorbs 10% – 15% of dietary calcium compared to 30% to 40% with adequate vitamin D levels.

A meta-analysis of 12 randomised controlled trials has shown vitamin D to reduce the risk of fractures in the elderly. Vitamin D significantly reduced the risk of hip fracture by 26% and non-vertebral fracture by 23%. Alongside adequate calcium consumption, vitamin D may help to reduce the risk of falls that leads to fractures, by playing a role in musculoskeletal function. Vitamin D has been shown to have direct effects on muscular function, modulated by specific vitamin D receptors present on human muscle tissue. In a separate, double-blind RCT, vitamin D taken with calcium significantly improved musculoskeletal function, reducing the amount of falls in older adults by 49% over 3 months.
