The Active Ingredient Is: L-Tyrosine (Free-form)

L-Tyrosine is an amino acid used in the body's production of key neurotransmitters involved in mental function and mood regulation. This product provides free-form L-Tyrosine in powder form for flexible use.

It is supplied as pure L-Tyrosine without additives, fillers or flavourings, suitable for vegetarian and vegan use.

What Does L-Tyrosine Do?

L-Tyrosine plays a role in the production of dopamine, norepinephrine and epinephrine, which are involved in cognitive function and the body's stress response. It may support thyroid hormone production, which can influence metabolic functions in the body.

Dr. Deijen of University of Groningen found that tyrosine can help support cognitive performance under stress, reflecting its involvement in neurotransmitter synthesis and brain function.

This information aligns with EFSA-style understanding that amino acids contribute to normal brain function and metabolism through their roles in neurotransmitter production.
