Why it matters

Protein provides the amino acid precursors for neurotransmitters including dopamine, serotonin, and noradrenaline — the molecules your brain uses for focus, motivation, mood, and alertness. On days when your protein intake is low, your brain may have fewer raw materials to produce these neurotransmitters, resulting in reduced focus, lower mood, and slower cognitive function. The effect varies from person to person based on how efficiently your body produces neurotransmitters, your baseline diet, and your current health status. Normal helps you find whether protein is a consistent focus predictor for your brain.

When Normal helps

Normal tracks your protein intake alongside your focus and cognitive performance over time. It finds whether low-protein days consistently precede reduced focus for you and what your personal protein threshold looks like for maintaining cognitive performance.

How Normal finds it

Tell Normal what you eat and how your focus is. Over three to four weeks it finds whether protein is a consistent predictor of your cognitive performance and what level seems to matter for your brain specifically.

Start with your body

Normal finds the pattern behind how you feel.

Tell Normal what happened in plain language. It connects your food, sleep, movement, stress, and symptoms over time.
