1. Supports Healthy Mood and Stress Response: L-Tyrosine is a precursor to important neurotransmitters such as dopamine, norepinephrine, and epinephrine, which play a crucial role in regulating mood and managing stress. Supplementing with L-Tyrosine can help support a healthy mood and better manage stress levels.
2. Enhances Cognitive Function: L-Tyrosine is also involved in the production of thyroid hormones, which are essential for regulating metabolism and supporting cognitive function. In addition, L-Tyrosine has been shown to improve cognitive performance during periods of stress and fatigue, making it a valuable supplement for individuals looking to improve their mental clarity and focus.

This label presents L-Tyrosine as the main active ingredient, reflecting its role as a crucial building block for neurotransmitter production and mental performance relevant to everyday cognitive tasks.
