What should I know about vitamin d 3 mangel symptome?

The provided contexts contain no specific information about vitamin D3 deficiency symptoms. However, well-established medical knowledge includes: bone pain, muscle weakness, increased susceptibility to infections, fatigue, and depressed mood. Severe deficiency can cause rickets in children or osteomalacia in adults. Evidence for these symptoms is strong (clinical guidelines), but the contexts do not provide direct sources. MyBody-X tests can measure vitamin D levels, but a single lab result is not a diagnosis. If deficiency is suspected, consult a physician for proper testing and supplementation advice. The contexts cover unrelated topics (pharmacogenetics, vitamin B complex, telomerase) and are not applicable here.
