From the Research
Symptoms of low vitamin D can include bone pain, muscle weakness, falls, low bone mass, and fractures, as well as fatigue, mood changes, and impaired wound healing, and if left untreated, can lead to severe bone disorders like osteomalacia in adults. The most recent and highest quality study 1 suggests that vitamin D deficiency can have a significant impact on overall health, and that supplementation with calcium and vitamin D can improve bone mineral density. Common signs of vitamin D deficiency include:
- Fatigue
- Bone pain
- Muscle weakness
- Muscle aches or cramps
- Mood changes like depression Some people may also experience:
- Impaired wound healing
- Hair loss
- Increased susceptibility to infections Severe deficiency can lead to bone disorders like:
- Rickets in children
- Osteomalacia in adults
- Bone pain and deformities Many people with low vitamin D levels may not show obvious symptoms initially, making it difficult to recognize without blood testing. Vitamin D supplementation, typically 600-2000 IU daily for adults, may be recommended under medical supervision to prevent and treat vitamin D deficiency 1. Risk factors for deficiency include:
- Limited sun exposure
- Darker skin tone
- Obesity
- Age over 65
- Certain medical conditions affecting nutrient absorption It is essential to note that vitamin D plays a crucial role in maintaining bone health, supporting immune function, reducing inflammation, and regulating cell growth. If you suspect low vitamin D, a simple blood test can confirm levels, and supplementation may be recommended under medical supervision. The study by 2 also highlights the importance of recognizing the signs and symptoms of vitamin D deficiency to make a proper diagnosis and prescribe appropriate treatment. Additionally, the study by 1 suggests that higher doses of calcium plus vitamin D supplements may have better cognitive effects compared to lower doses.
