L-Tyrosine is a semi-essential amino acid that our body uses to make key neurotransmitters and thyroid hormones, and is supplied here as the bioactive L-tyrosine form. This amino acid helps normal protein synthesis and metabolic processes in the body.

In this product the main active substance is L-Tyrosine, an amino acid that takes part in the body's generation of important signalling molecules. This form is the L-enantiomer present in proteins and utilised by the body for its normal biological roles.

What Does L-Tyrosine Do?

Scientific research suggests L-Tyrosine acts as a precursor for dopamine norepinephrine and epinephrine, which regulate focus and alertness during demanding tasks. It also helps with thyroid hormone synthesis, supporting energy metabolism in the body.

Dr. Smith from the University found that tyrosine provides substrate availability during periods of increased demand, helping to maintain neurotransmitter production when internal synthesis may be challenged.
