Introduction

Although many people with vitamin D deficiency do not experience any symptoms, there are a number of signs that may indicate insufficient levels of this important vitamin.

Vitamin D, also known as the sunshine vitamin, is crucial for building and maintaining healthy bones. A deficiency in vitamin D can negatively impact a person’s overall health.

Symptoms of Vitamin D Deficiency

Claire Barnes, a registered dietician at Bio-Kult, has identified several symptoms that could indicate a deficiency of the sunshine vitamin.

1. Fatigue

Self-reported fatigue and low energy levels are associated with low vitamin D levels.

Claire explains, “Research shows that taking vitamin D supplements can significantly reduce fatigue in people with multiple sclerosis, a condition known for causing fatigue as a common symptom.”

2. Bad mood

Increased levels of vitamin D receptors have been found in areas of the brain associated with mood regulation.

Claire points out, “Studies have shown that people with depression tend to have lower levels of vitamin D compared to healthy individuals. Interestingly, those with the lowest levels of vitamin D are more likely to develop depression. Clinical studies have also demonstrated improved levels of depression when taking vitamin D supplements.”

3. Poor oral health

Optimal levels of vitamin D are necessary for calcium absorption, which is important for dental health.

Claire explains, “Vitamin D plays a key role in the mineralization of bones and teeth. Good levels of the vitamin are associated with improved oral health throughout life. Conversely, vitamin D deficiency is directly linked to oral diseases.”

4. Bone and muscle pain

Vitamin D is essential for muscle and bone health. Low levels of vitamin D can lead to decreased calcium absorption, which promotes bone resorption and ultimately weakens bone tissue.

Claire states, “Muscle pain can have various causes, but evidence suggests that vitamin D deficiency may be a contributing factor. A review of studies involving over 3,000 participants suggests that vitamin D supplements may play a role in managing chronic pain.”

5. Frequent illness

Vitamin D plays a crucial role in modulating the immune system.

Claire explains, “Scientific evidence strongly supports the effects of vitamin D on immune system function. Vitamin D deficiency can dysregulate the immune system, leading to either immunosuppression or an inappropriate immune response.”

6. Digestive system issues

Vitamin D also plays a role in maintaining gut health.

Claire reveals, “Research shows that optimal vitamin D levels are important for intestinal homeostasis and modulation of the gut microbiota. Vitamin D supplementation has been shown to reduce harmful bacteria and increase friendly bacteria in the upper gastrointestinal tract. Recent studies also suggest that live bacteria may increase the expression and activity of vitamin D receptors, leading to higher vitamin D levels in the host.”
