Hemoglobin

Included in Essential Labs
Why we test it
Hemoglobin carries oxygen from the lungs to the body. The brain uses 20% of the body's oxygen, so low levels reduce delivery and explain why fatigue and brain fog are early symptoms of anemia.
BetterBrain target

The brain consumes 20% of the body's oxygen. Adequate hemoglobin is critical for neural function.
