Preparation
Vitamin B12 is the nerve vitamin — essential for the sheath that insulates your nerves, for red blood cell formation, and for DNA synthesis. B12 deficiency is extraordinarily common in India for one simple reason: it exists almost entirely in animal foods, so vegetarians are structurally at risk, and many non-vegetarians absorb it poorly too.
The deficiency announces itself subtly — tingling or numbness in hands and feet, fatigue that iron does not fix, brain fog, memory slips, mouth ulcers — and can progress to genuine nerve damage if ignored for years. The good news: it is easily tested and easily treated.
This blood test measures your circulating B12 at ₹399 with home collection. No fasting needed. If your value is low, your doctor will advise tablets or injections and a repeat to confirm the refill — the test at ₹399 makes that follow-up effortless.
Yes — this is the single most likely deficiency in Indian vegetarians. Plant foods contain virtually no absorbable B12, so most vegetarians need supplementation eventually. Testing shows whether you are already there.
