More info

5-HTP Griffonia Douglas 120 capsules Griffonia Douglas Laboratories is a supplement rich in the amino acid L-5- hydroxytryptophan (5 -HTP ) , proporcinando 500mg of this amino acid in each capsule. Serotonin is an important brain neurotransmitter , is key in the regulation of appetite , mood, and melatonin production . The presence of serotonin in the brain is associated with a balanced emotional state . This is accomplished in part by decreasing the activity of certain hormones excitation , including dopamine and noradrenaline. Serotonin also acts as a satiety signal in the brain , which naturally regulate food intake . Furthermore, as a precursor to melatonin, serotonin is involved in the regulation of sleep patterns . Serotonin is unable to cross the blood brain barrier and it is synthesized in the brain. Tryptophan, an essential amino acid is a precursor for the synthesis of serotonin . Tryptophan hematoencefálic crosses the barrier and becomes L-5- Hydroxytryptophan (5-HTP ), which in turn is converted into serotonin . Unfortunately , tryptophan faces many obstacles during his journey in brain tissue . First, food intake directly affects the body's levels of tryptophan, since the body can not produce endogenously . High protein diets often provide higher amounts of tryptophan , but high intake of carbohydrates appears to increase the absorption of tryptophan in the brain. Secondly, tryptophan has to compete with other amino acids for entry into the brain. Finally, the tryptophan can be captured by other tissues or protein to form niacin synthesis , and therefore is not exclusively for use in the brain. As an intermediate in the metabolic conversion of tryptophan to serotonin, 5 -HTP may also serve as a precursor of serotonin . 5-HTP offers a number of advantages over tryptophan . 5-HTP is obtained naturally from the seeds of the plant Griffonia , unlike tryptophan, which is produced synthetically or by bacterial fermentation . 5-HTP through the brain more easily than tryptophan as it is capable of crossing the blood brain barrier without competition for their uptake . 5-HTP is significantly more effective than tryptophan, a capsule of 50 mg of 5-HTP is approximately equivalent to 500 mg of tryptophan.
