Signs you may have a Vitamin D deficiency

The symptoms of a vitamin D deficiency are often very subtle & may seem unconnected. However the impact of low vitamin D levels can be devastating & confusing for the individuals experiencing it. Those who are considered more at risk of developing a deficiency are the following groups:

  • The elderly
  • People with dark skin
  • The overweight or obese
  • Those with a diet low in fish or dairy
  • People who spend a large part of their time indoors
  • Those who cover their skin or wear a high factor sun cream

The most common symptoms are:

  • Developing illnesses, and infections often, especially colds or the flu. A low-functioning immune system is a sign of reduced vitamin D levels.
  • Feeling tired/fatigued: Low levels of vitamin D in the blood can contribute to feelings of fatigue & tiredness to the point that quality of life is affected. Once the levels are brought back up to expected levels, studies show that energy levels recover quickly.
  • Muscle, bone or back pain: Vitamin D improves the absorption of calcium into the bone so a lack of it can mean people experience pain severe enough to prevent them going about their normal routines. Bone density can also be affected by vitamin D levels.
  • Low mood, depression & anxiety could all be signs that your vitamin D levels need a boost. Some studies have shown that taking supplements can ease symptoms of depression & anxiety & improve general mood.
  • Slow healing wounds: Studies suggest that adequate levels of vitamin D in the body increases the production of compounds required for skin to heal after an injury, wound or surgery. It is also necessary for fighting inflammation & infection meaning that people with good levels of vitamin D tend to bounce back quicker from wounds and injuries.
  • Hair loss, especially in women could be a sign of lower levels of vitamin D.

If you are experiencing these symptoms it is important to speak to your doctor. They may want to carry out a blood test and, depending on the results can prescribe a course of vitamin boosters if needed.
