Periodar is a food supplement with a magnesium and Griffonia seed extract base. It is helpful in overcoming cases of stress as it restores the neuro-muscular balance.
More specifically, thanks to its high content of 5-hydroxytryptophan (5-HTP), a precursor of serotonin, Griffonia helps prevent mood swings and contributes to relaxation and mental well-being. The magnesium contained in the formula helps overcome tiredness and fatigue as well as maintaining the normal functioning of the nervous and muscular systems.


Magnesium oxide, Griffonia simplicifolia dried extract (Griffonia simplicifolia (DC) Baill., seeds) titrated in 5-hydroxytryptophan.

Periodar is helpful for combating disorders linked to stressful conditions or periods of intense psycho-physical activity.
The chewable Periodar tablets contain magnesium and Griffonia, a natural source of 5- hydroxytryptophan (5-HTP).

  • 5-hydroxytryptophan (5-HTP): This is a precursor of serotonin, a neurotransmitter synthesised in the brain and in the gastrointestinal tract which has numerous effects on the body: the most important include regulation of mood, sleep, gastrointestinal motility and appetite. It is also involved in disorders such as migraine, depression and anxiety.

Unlike tryptophan, its direct precursor, 5-hydroxytryptophan is able to cross the haemato-encephalic (blood-brain) barrier and is converted into serotonin in the cerebral tissue by a specific enzyme (5-hydroxytryptophan-decarboxylasei).
Periodar restores the physiological levels of 5-HTP, thereby making it possible to rebalance the physiological levels of serotonin. A serotonin deficiency may also give rise to muscular tension that is the cause of headaches, cramps and myalgia.

  • Magnesium: Periodar is helpful in cases of magnesium deficiency. This mineral has a positive effect on the relaxation of muscle fibres and plays a well-known role in the onset of headaches.
    Magnesium is an essential ion for the stability of cell membranes and contributes towards maintaining optimal ionic trans-membrane transport, a fundamental process for muscle contraction and nerve conduction.
