Metabolic
Biomarker

Ferritin

Included in Essential Labs
Why we test it
Ferritin stores and releases iron for red blood cell production. Low levels cause fatigue, especially in women. Both deficiency and overload affect the brain: low iron impairs oxygen delivery, excess promotes oxidative damage.
BetterBrain target
40-100 ng/mL (women) / 50-150 ng/mL (men)
Both iron deficiency and overload affect the brain. Our range is tighter on both ends than standard labs.
What you Can do
  1. Iron-rich foods (if low)
  2. Blood donation (if high)
  3. Vitamin C with iron-rich foods
  4. Mediterranean diet
