The consequences of long-term tryptophan supplementation: Interactions between dopamine and tryptophan

Lists the long-term administration of tryptophan to a disturbance in dopamine metabolism?

As a result of a long-term use of Tryp with stimulation of central serotonin synthesis can lead to a relative lack of dopamine (Andrews et al. 1978 Hashiguti et al. 1993). This interaction is observed only after several months to years Tryp resource. Several studies suggest that serotonin and dopamine synthesis is regulated in dependence on each other (Trouvin et al. 1991). An increased synthesis of serotonin has an inhibitory effect on dopamine synthesis and vice versa (Hashiguti et al. 1993). The permanent stimulation of serotonin synthesis by the administration of tryptophan seems long to a reduced central dopamine activity result. The probatory administration of L-dopa can be considered for positive response as an indication of the existence of a relative lack of dopamine. To prevent this imbalance of dopamine and serotonin, it seems necessary at times to stimulate the central dopamine synthesis. There is evidence that can stimulate the synthesis of the neurotransmitter dopamine in a similar manner to serotonin by the administration of the precursor tyrosine (Acworth et al. 1988 Rasmussen et al. 1983, Benedict et al. In 1983, During et al. 1989). One way to compensate for this imbalance between serotonin and dopamine, is therefore in the gift of tyrosine in the revenue from the Tryp breaks in a dose of 20 mg / kg (Badawy et Williams 1982). This early functional dopamine deficiency may manifest in healthy individuals under long-term administration Tryp especially during exercise. When running benefit may show a deterioration in mileage, which is subjectively perceived as a kind of rigidity, as "tough running motion" in analogy to the "wächsenden" resistance in the context of Parkinson's disease. The movement does not seem so fluid, the rotor requires much more drive to get the same performance level. Under L-dopa administration (daily 100 mg + 25 mg carbidopa), this deficit improved within 5 to 7 days. It is striking that when corrected for the relative lack of dopamine observed increased strain readiness, improved motivation and a generally increased drive. Since influence the dopamine and serotonin synthesis each other if neither tyrosine nor L-dopa are administered with Tryp. Sequential administration, however, permits the correction of relative dopamine deficiency. prevent

To a disturbance in dopamine metabolism by the unilateral tryptophan, regular supplementation with Tyrosine is recommended. Treatment with L-dopa (with carbidopa) should the situation are reserved, at which the adjusted basis of a long-term unilateral stimulation of serotonin synthesis with Tryp a clinically apparent, relative lack of dopamine.

Treatment with tryptophan - what dosage?

Therapeutic effects of tryptophan

tryptophan is currently approved in Germany as a drug for the treatment of sleep disorders. L-tryptophan is a non-prescription medicine and is offered a dose of 500 mg per tablet (eg L-tryptophan ratiopharm). In the scientific literature that has always stood another application in focus: the treatment of depressive disorders. As an important precursor to the formation of serotonin (5-hydroxytryptamine) may intervene Tryp directly in the metabolism of this vital neurotransmitter.

The influence of the serotonin system to the chemical class of selective serotonin reuptake inhibitors (SSRIs) has in the past 20 years as the most effective therapeutic option for the treatment of depression emerged (Petersen et al. 2002). Besides the influence of depressive symptoms has the Tryp-handed to be effective in reducing interference of affectivity, in particular for the treatment of severe impulsivity proved (aan Rot et al het. 2006).

When seasonal affective disorder (SAD), the so-called winter depression, is deteriorating because of the shortened days with the absence of daylight influence the mood of sensitive people. Besides the well-documented effectiveness in its light therapy (10,000 lux for at least 30 min) also seems to Tryp administration to have an additional positive effect (Lam et al. 1997). Moreover there are indications that a Tryp-dose positive effect on cognitive abilities (Haider et al. 2006).

A major difference compared to the Tryp as a standard of care for depressive disorders apply serotonin reuptake inhibitors is the time to onset. While the Tryp-effect detectable on the symptoms is usually after about a week (. Levitan et al 2000), the serotonin reuptake inhibitors require significantly longer (2-3 weeks) report to the patient about an improvement in symptoms. Moreover there are indications that can enhance the effect of serotonin reuptake inhibitors by the addition of Tryp (Lowe et al. 2006, Levitan et al. 2000).

Under what doses of tryptophan, a sufficient therapeutic effect can be expected?

The assessed as safe and effective dose range of tryptophan with 0.4 to 4 g daily given (Monographie L-tryptophan). In numerous studies on the treatment of depression with tryptophan doses were administered daily 6 g (Herrington et al. In 1974, D'Elia et al. 1977, Steinberg et al. 1999). As a complementary therapy Tryp was also used in doses of 3 g daily successful (Lam et al. 1997). As a sleep aid, however, are already doses of ≥ 1 g sufficiently effective. The repeated administration of daily 1,5 - 3 g Tryp about 2 to 3 weeks seems sufficient to offset a relative lack of central serotonin and make positive changes happen (aan het Rot et al 2006).. A daily dose of 1.5 g Tryp is only sufficient when the conditions for admission are designed so that high concentrations of free Tryp effect at the blood-brain barrier for a sufficiently long period. The intake of eg 1.5 g Tryp together with a normal meal are not likely to increase the supply of free Tryp to the BH bound critical.

principle, the inclusion of Tryp together with protein-rich foods inappropriate influence on the central serotonin synthesis significantly. 3 g daily dose Tryp-sufficient only if the administration in the fasting state, ie,> 3 hours after the last and at least 2 hours before your next meal is - 1.5 are accordingly. Further optimized the concentration of free Tryp if the Tryp-taking after a long fasting period (the morning before the first meal) takes place. Under a long-lasting endurance exercise (eg running or cycling), without intermediate energy supply to be achieved almost perfect conditions to stimulate the inclusion of the CNS and the central serotonin synthesis (Chaouloff 1997).
