The Active Ingredient Is: L-Tyrosine (Pure crystalline)

L-Tyrosine is an essential amino acid the body uses to synthesise key brain chemicals. This product contains crystalline pure L-Tyrosine, designed for quality and allergen safety. The capsule uses bovine gelatin and common inactive ingredients to keep capsule integrity.

This form is described as crystalline pure L-Tyrosine and is represented as the primary active nutrient in this product.

What Does L-Tyrosine Do?

L-Tyrosine provides raw material for the production of catecholamine neurotransmitters, which are involved in brain signalling and mental function. It supports its role in normal neurotransmitter production and brain health processes.

This mechanism aligns with its described use as a precursor supplier to dopamine and related compounds, contributing to daily mental performance and resilience during stressful times.

This product is not intended to diagnose, treat, cure, or prevent any disease.
