Vitamin B12 & Folate
Measures both B12 and folate β the two vitamins most tied to energy, nerve health, and healthy red blood cells. One draw, results usually in 1β2 business days.
Vitamin B12 and folate work as a pair to make DNA and healthy red blood cells and to keep your nervous system running. A shortage of either can cause fatigue and anemia, and checking both together is the standard way to sort out the cause.
