FINALLY, A 5-HTP THAT PROVIDES ALL OF THE BENEFITS — AND NONE OF THE DRAWBACKS! Propriety sustained release technology makes 5-HTP work longer and better. Often allows you to take less... saving you money! Eliminates the nausea that often occurs with 5-HTP. Only the highest quality 5-HTP from Europe, not China. 5-HTP has a very short half-life in the body — only about 90 minutes. That means that it is gone from the body very rapidly after being consumed. This is the reason that most people who take 5-HTP often need to take many doses throughout the day in order to maintain the effect. The other problem with non-sustained release formulas is that when you dump 5-HTP into the GI tract all at once, it is rapidly converted to serotonin right there. What you really want though, is for the majority of 5-HTP to be converted to serotonin in the brain. Releasing it over a longer period of time allows the 5-HTP to be absorbed. Not only is this better for seeing a more long-lasting effect, but it can also help avoid stomach upset which some people experience as a side effect when 5-HTP is dumped into the intestinal tract all at once. For most people, sustained release technology will also provide the ability to take a lower dose of 5-HTP, while still having the same — if not even greater — benefits.
