Importance of Vitamin D for Overall Health
Having good levels of vitamin D in the body is crucial for various functions such as calcium absorption, fighting infections, and maintaining proper functioning of the nervous system and muscles.
The Role of Vitamin D in Bone Health
Vitamin D is essential for maintaining healthy bones, and a deficiency in this vitamin can weaken joints and increase the risk of stress fractures, which are small cracks in the bone. Stress fractures typically occur in weight-bearing bones of the lower leg and foot.
The Impact of Vitamin D on Mood and Immunity
Vitamin D deficiency may affect serotonin levels in the brain, which is known as the “happy hormone” responsible for maintaining mood and well-being. Additionally, vitamin D plays a crucial role in strengthening the immune system. Low levels of vitamin D may contribute to a weakened immune system, making individuals more susceptible to severe Covid-19 symptoms.
Recent research has shown that vitamin D supplements can reduce the risk of death and intensive care unit admission for people with Covid-19. However, the NHS states that there is currently insufficient evidence to support using vitamin D alone to prevent or treat Covid-19.
Sources of Vitamin D
The human body can produce vitamin D when the skin is exposed to sunlight. However, many people may not get enough sunlight, especially during winter, leading to a deficiency in vitamin D. To ensure an adequate intake of vitamin D, it is recommended to consume foods rich in this vitamin or consider taking a vitamin D supplement.
Food sources of vitamin D include oily fish (such as tuna, mackerel, and salmon), eggs, dairy products (milk and cheese), vitamin-enriched foods (cereals, bread, and juices), and mushrooms.
For individuals who do not regularly consume these vitamin D-rich foods and have limited sunlight exposure, a vitamin D supplement may be beneficial.
