Vitamin B12
Vitamin B12 is essential for energy production, red blood cell formation, brain function, and methylation. It helps convert food into energy and supports your nervous system. Low B12 can cause fatigue, brain fog, poor memory, mood issues, and even nerve problems. Total B12 doesn’t always reflect functional use—so levels should ideally be well above the deficiency cutoff.
