Normal Vitamin B12 levels but tiredness and tingling continue? A deficiency could be the reason
Many experience fatigue and cognitive issues despite normal Vitamin B12 levels due to functional deficiency, where the body can't utilize the nutrient effectively. Standard tests often miss this, as they measure total B12, not its active form. Advanced testing is recommended for accurate diagnosis and to prevent long-term complications.
