Signs You Might Have Vitamin D Deficiency

How Common is Vitamin D Deficiency?

Studies suggest that 40-60% of adults in the US may have suboptimal vitamin D levels. Deficiency is even more common in northern latitudes, among older adults, and in people with darker skin tones.

Warning Signs to Watch For

• Frequent illness or infections
• Fatigue and tiredness, even after adequate sleep
• Bone and back pain
• Depression and low mood
• Slow wound healing
• Muscle pain and weakness
• Hair loss (in severe cases)

Who is at Risk?

Higher risk groups include: people who spend little time outdoors, those with darker skin, older adults, people with obesity, and those with conditions affecting fat absorption.

What to Do

If you suspect vitamin D deficiency, speak with your healthcare provider about getting a blood test (25-OH vitamin D test). Treatment typically involves supplementation and increased sun exposure. Do not self-diagnose or self-treat without medical guidance.
