Our moods are determined by neurotransmitters which activate our brain. These neurotransmitters are synthesised from amino acids alongside vitamin and mineral cofactors.

There are two types:

  • Invigorating neurotransmitters, promoting pleasure, dynamism, motivation, energy and alertness. Among the most important: dopamine and noradrenaline, which are synthesised by tyrosine.
  • Others which might be thought of as "brakes", allowing self-control, regulation of emotional state, maintenance of a stable mood and sleep. The most significant are serotonin and melatonin, molecules manufactured from tryptophan.

Stress, when it becomes chronic, plays havoc with our brain, creating an imbalance in neurotransmitter synthesis.

The availability of amino acid precursors, tyrosine and tryptophan, is disrupted, and the vitamins and minerals that support their synthesis are consumed in excess.

This imbalance will impact the whole body, leading to the stress we all know too well: fatigue, mood swings, lack of motivation, nervousness, anxiety, etc.

Subjected to stress, you become anxious and lack motivation, or rather the opposite, you are looking for increased peace of mind? ERGYSTRESS Activ and ERGYSTRESS Seren will meet your expectations. Made up, respectively, of tyrosine and tryptophan, combined with plants, vitamins and minerals, they adapt to your needs.


Consisting of:

  • Tyrosine, an amino acid precursor of dopamine and noradrenaline, which gives you dynamism and motivation.
  • Bacopa, a plant recognised for helping the body deal with stress and for aiding concentration.
  • Vitamin C, a cofactor in neurotransmitter synthesis, which also helps reduce fatigue and supports normal psychological functioning.
  • B group vitamins, which are active in the metabolism of neurotransmitters, particularly vitamin B5 which supports intellectual performance including memory, concentration and reasoning.
  • Marine magnesium, also a cofactor of dopamine, which helps to reduce fatigue and maintain normal psychological functions.

When is it recommended? To combat lack of motivation, overwork, apathy and fatigue.

 Instructions for use: 1 to 3 capsule(s) per day.
