    5-HTP (50MG)- Douglas Laboratories 100 Capsules in New Zealand 

    5-HTP( brain serotonin precursor) provided by Douglas Laboratories®, contains 50 mg of natural L-5-Hydroxytryptophan (5-HTP) extracted from seeds of the Griffonia plant in each vegetarian capsule. 5-HTP crosses into the brain more readily than tryptophan as it is able to cross the blood-brain barrier without competition for uptake. 5-HTP is significantly more effective than tryptophan. In clinical practice, it has been commonly accepted that 50 mg of 5-HTP is roughly equivalent to 500 mg of tryptophan. Research studies have shown 5-HTP to be safe at levels as high as 900 mg. As a result, 5-HTP is a safe and effective means of increasing brain serotonin levels.
