What are the symptoms of low vitamin D?
Quick answer:Â Low vitamin D often has no obvious symptoms - which is why it's called a "silent deficiency." When symptoms do appear, the most common include fatigue, bone or muscle aches, frequent illness, low mood, and difficulty concentrating.
Because vitamin D receptors are found in nearly every tissue in the body, deficiency can show up in unexpected ways.
Most common symptoms
Persistent fatigue not explained by sleep; bone pain or tenderness; muscle weakness or cramps; frequent colds or infections; low mood, especially in winter; brain fog or difficulty concentrating.
Less obvious signs
Hair thinning, slow wound healing, joint pain, and increased sensitivity to pain have all been associated with low vitamin D in research - though these are less specific and can have many causes.
Why is deficiency so hard to detect?
Who is most at risk in Canada?
- Anyone living above 50° latitude (most of Canada), older adults, darker-skinned individuals, those who work indoors, postmenopausal women, and people on certain medications that affect vitamin D metabolism.
