Vitamin tests compared
Both are common deficiencies behind tiredness — but they cause different symptoms. Here's how to choose, or test both.
The bottom line
These test different deficiencies, so it isn't really one-or-the-other. Vitamin D deficiency is very common in India and shows up as fatigue, bone or muscle aches and low mood. B12 deficiency causes tiredness with nerve symptoms — tingling, numbness — and is especially common in vegetarians. If your symptoms point clearly one way, start there; if you're simply tired and want the common causes ruled out, testing both together is the sensible move.
You have bone/muscle aches, low mood, or little sun exposure.

See price & bookVitamin D and B12 are the two deficiencies most often behind unexplained tiredness in Indian adults, but they affect the body differently. Vitamin D matters for bones, muscles and mood, and deficiency is widespread because of limited sun exposure and darker skin.
B12 is needed for nerves and red blood cell formation, and because it comes mainly from animal foods, deficiency is common in vegetarians and the elderly. Its shortfall can cause tingling, numbness and memory fog on top of fatigue. When symptoms don't clearly point one way, testing both is efficient.
