Griffonia simplicifolia is an African plant the seeds of which are naturally rich in L-5-HTP (Hydroxytriptophan), the direct precursor of serotonin, one of the principal neurotransmitters in the brain.

Serotonin is involved in sleep as well as managing stress, stimulating its production reduces states of depression or anxiety and helps you find quality sleep again.

Griffonia is therefore an extremely effective natural remedy to help restore calm, peace of mind and sleep quality.

The L-5-HTP present in Griffonia simplicifolia does not have the side effects of synthetic anti-depressants and carries no risk of addiction. It reduces anxiety and depression without interfering with the brain’s natural functioning, unlike synthetic anti-depressants.

Detailed information

Griffonia simplicifolia is an African plant whose seeds are naturally rich in L-5-HTP (Hydroxytriptophan), a direct precursor of serotonin. Griffonia simplicifolia is therefore a natural, direct and efficient way of finding calm, serenity and quality sleep.

Serotonin is one of the principal neuro-transmitters of the brain. It is notably active in sleep as a precursor of melatonin as well as for the management of stress. With age, serotonin production declines. In addition, daily stress can also reduce its level leading to moods of depression, fatigue, anxiety and insomnia.

The L-5-HTP found in Griffonia simplicifolia is the same amino acid which our body produces naturally. It is vital for the regular replenishment of serotonin and can reduce anxiousness and depression without any aggressive effect on the brain’s natural functioning, in contrast to synthetic anti-depressants. The latter effectively block the natural “re-capture” of serotonin by cerebral synapses, which lead to certain aggravating side-effects such as changes in blood-pressure, palpitations, constipation, nausea and headaches, not to mention the possibility of dependence. Griffonia is shown to be as efficient as synthetic anxiolytics and anti-depressants but without causing any side-effects.

Several studies also show that L-5-HTP can contribute to a reduction in the frequency and intensity of headaches.

L-5-HTP additionally has a very positive effect in case of fibromalgia. The link between low levels of serotonin and fibromalgia as well as the positive effect of L-5-HTP for the relief of the symptoms of this illness have now been shown.

L-5-HTP also acts as an appetite suppressant and can be helpful in following a weight-loss diet since serotonin is active in appetite inhibition for glucidic foodstuffs, which are rich in calories.
