Studies have shown how 5-HTP may help to support quality of sleep, whilst also potentially helping to support good mental well-being. Clinical trials have shown how 5-HTP may also help to contribute towards mood regulation and the production of the sleep hormone melatonin, to help promote healthy sleep patterns. 5-HTP has also been shown to help support healthy weight management.
