Vitamin D plays an important role in many body systems, including the control of cell growth and the immune response. Since the substance also helps regulate the amount of calcium and phosphorus in the body, it is essential for maintaining healthy bones, teeth and muscles. Vitamin D is present naturally in very few foods and often in too small doses to help a person meet their daily needs.
According to a 2020 study, 50% of the world’s population suffers from vitamin D deficiency. Deficiency is highest in the elderly and obese. And although the symptoms of this condition are often vague, one can detect them by several main signs.
Fatigue and muscle weakness
Because vitamin D is key to bone health, not getting enough can cause muscle weakness, leading to constant fatigue. According to a study published in the NLM, taking supplemental amounts of vitamin D for 5 weeks significantly alleviated this affliction.
Bone and joint pain
Vitamin D may increase bone mass and prevent bone loss, says the PubMed research article. Doctors warn that if bone or joint pain becomes regular, vitamin D blood levels should be checked. Perhaps the disease is the result of the development of rheumatoid arthritis. A 2012 study found that vitamin D deficiency is associated with an increased risk of developing this condition. Slow wound healing
If a wound takes longer than usual to heal, this may be a sign of low vitamin D. In vitro studies have shown that vitamin D plays an important role in this process by regulating the growth factors of new tissue.
Frequent infections or illnesses
Vitamin D supports the immune system – it plays the role of a reliable assistant in suppressing inflammatory processes. The vitamin helps prevent upper respiratory tract infections. Taking vitamin D may be advisable in the fall and winter. However, it is important to consult a doctor before using supplements to get advice on the correct dosage.
