The presence of serotonin in the brain is associated with a balanced emotional state.  This is achieved in part by decreasing the activity of certain excitatory hormones, including dopamine and noradrenaline. Serotonin also acts as a satiety signal in the brain, thereby naturally regulating food intake.  Additionally, as a precursor of melatonin, serotonin is involved in regulating sleep patterns. \u003c\/p\u003e\n\u003cp\u003e5-HTP is derived naturally from the seeds of the Griffonia plant, unlike tryptophan which is produced synthetically or through bacterial fermentation.  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. Finally, 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 brain serotonin levels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSUGGESTED USE\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eOne to two capsules per day, between meals or as directed by a physician. Vitamin B6 is necessary for the conversion of 5-HTP to serotonin; thus, to derive optimal benefits of 5-HTP, one must ensure an adequate intake of vitamin B6.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSIDE EFFECTS\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eNo adverse side effects have been reported.\u003c\/span\u003e\u003c\/p\u003e","brand":"Douglas Laboratories","offers":[{"title":"Default Title","offer_id":41826003779680,"sku":"","price":635.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0631\/4691\/7984\/files\/2025-05-12T183814.252.png?v=1747046359","url":"https:\/\/ipurecare.com\/en\/products\/douglas-labs-5-htp-50mg-100-capsules","provider":"iPureCare ","version":"1.0","type":"link"}
