About Vitamin B12
Vitamin B12 is essential for nerve function and red blood cell production, and low levels can quietly cause tiredness, tingling in the hands or feet, or memory issues before anyone thinks to test for it.
It is especially common in people following a vegetarian diet, since B12 comes mainly from animal products, as well as in older adults whose bodies absorb it less efficiently over time.
The test itself is simple, just a blood draw with no fasting needed, and your report is ready the same day so your doctor can start supplementation quickly if levels are low.
How to Prepare
- No fasting required.
- Let us know if you're already taking a B12 supplement or injection, as it can affect your result.
