Lack of concentration, low motivation? This food supplement contains 500mg of L-tyrosine per capsule. Tyrosine Max is involved in the production of catecholamines.
- Energy Dopamine is a neurotransmitter involved in movement functions. It is involved in motor control.
- Brain Tyrosine is an amino acid precursor of dopamine. Dopamine is a neurotransmitter involved in intellectual and emotional functions. It is involved in attention, motivation and pleasure.

Tyrosine promotes the production of catecholamines which contribute to optimising cognitive performance.
Supplies the body with :
Tyrosine taken on an empty stomach penetrates the blood-brain barrier for conversion in the brain. A fraction of it is then converted to L-DOPA through the action of an enzyme called tyrosine hydroxylase (4), which is the catalyst for conversion to dopamine.
Studies show that these conversions are increased in situations of stress or intense cognitive exercise [1-2-3-4]. In the medium term, stress is known to reduce the level of catecholamines, thus decreasing cognitive performance, probably due to the depletion of the amino acids essential for their synthesis (dopamine - noradrenaline). Tyrosine deficiency can lead to apathy, concentration, memory and vigilance problems, and in severe cases to burn-out and hyperactivity. This deficiency can potentially cause restless legs syndrome, which is accentuated at night (tingling, pins and need for movement).
In mood disorders caused by premenstrual syndrome (PMS), the amount of free L-tyrosine decreases significantly, causing stress and depression. The lack of serotonin accentuates this phenomenon. Finally, L-tyrosine is the direct precursor of thyroid hormones producing thyroxine (T4) in the presence of iodine and B vitamins. We recommend combining tyrosine with a course of Multi-Men/Fem to regulate the functioning of the thyroid gland.
