7 Signs You May Have Vitamin D Deficiency

4 min read·20 May 2026

Vitamin D helps your body absorb calcium, keep bones strong and support immunity. Despite plenty of sunshine, deficiency is very common in India — including in Bareilly — because of indoor lifestyles, covered clothing and diet.

Common signs of low Vitamin D

  • Constant tiredness or low energy that doesn't improve with rest.
  • Bone or lower-back pain, and aching muscles.
  • Frequent colds or infections — vitamin D supports immune defence.
  • Hair thinning and slow wound healing.
  • Low mood, especially in winter.
  • Muscle weakness or cramps.
  • Bone fragility in older adults.

Who should get tested?

Adults who stay mostly indoors, people over 50, pregnant women, and anyone with the symptoms above. A simple blood test called Vitamin D (25-OH) measures your level — no fasting needed.
