What is 5-htp?
- 5-htp crosses the blood-brain barrier and goes through a decarboxylase to become serotonin (5-ht).
- absorption of 5-htp is not influenced by other amino acids & therefore it can be taken with or without meals, without losing its efficacy.
- 5-htp has a much higher efficacy than tryptophan which is available in small amounts in foods such as red meats & seeds because tryptophan cannot cross the blood brain barrier without the help of transporter molecules.
- the therapeutic administration of 5-HTP may be efficient in depression, fibromyalgia, suppressing appetite and insomnia [1, 2, 3, 4, 5].
