CSTC Loop

Calm circuits. Clear thinking.

The CSTC Loop (Cortico-Striato-Thalamo-Cortical circuit) governs:

  • Focus

  • Emotional regulation

  • Impulse control

  • Stress processing

  • Decision-making

When dysregulated, people fall into mental “loops”: overthinking, reactivity, stress spirals, mood swings, difficulty shifting gears.
Our stress, neurotransmitter, and sleep-support formulas help restore balance to the circuit that controls your everyday choices.
