Prof. William Dalton, Ph.D.The importance of vitamin D becomes apparent at the time of deficiency. Your body sends signals, such as bone pain and muscle weakness. First showing mildly and then worsening. Early recognition is important to avoid serious health implications.
I have diagnosed insufficient levels in patients who had ignored their fatigue for a long time. The earliest signs typically included chronic fatigue and mood fluctuations. Consequently, muscle aches developed, particularly in the back and legs. These signs appeared months earlier than the more serious problem would have created in the bones.
Early Indicators
- Persistent fatigue unrelieved by sleep
- Frequent muscle cramps or weakness
- Mood fluctuations and irritability
- Recurring respiratory infections
Advanced Symptoms
- Deep bone pain in spine, hips, or ribs
- Difficulty standing from seated position
- Hair loss and slow wound healing
- Bone deformities in children (rickets)
Emergency Signs
- Severe muscle spasms (tetany)
- Pathological bone fractures
- Seizures from calcium imbalance
- Cardiomyopathy in extreme cases
Deficiency manifests differently in various age groups. Children will present with skeletal deformities; one example of this would be knock-knees. Adults may encounter bone softening known as osteomalacia. Seniors experience increased fracture risk. All age groups experience immune deficiency; cough and cold can persist for weeks.
Assess test levels when symptoms are consistent with risk factors. Regular testing is necessary for individuals with dark skin. Residents in northern climates should test their levels before the winter season approaches and request a 25(OH)D blood test every year. If your levels are below 20 ng/mL, you have a confirmed deficiency, and treatment is warranted.
Act quickly to prevent permanent consequences. Begin taking additional supplements as soon as you notice a decrease in your symptoms. Together with calcium, magnesium should be taken to enhance absorption rates. Pain associated with increased bone density typically diminishes in 2-4 weeks. Generally, full recovery takes between 3 and 6 months.
