Serotonin is a neurotransmitter produced by our bodies to facilitate communication between our brain cells and our nervous system. Most of our brain cells are influenced in some way by serotonin‚ these include the cells linked with mood‚ appetite‚ sleep‚ certain social behaviors‚ plus more. As such‚ serotonin is extremely essential for maintaining not only our physical health‚ but our emotional health as well. Some research suggests that there is a link between serotonin and depression. Although the specific details of the how serotonin affect depression aren't known‚ there are several possible theories such as a low production of serotonin‚ failure of serotonin neurotransmitters to arrive at receptor sites‚ or a low amount of tryptophan in our bodies. Tryptophan is the amino acid from which serotonin is created.

If you feel like a serotonin boost is something you need‚ consider Progressive Labs' 5-Hydroxy L-Tryptophan‚ a 5-HTP supplement derived from griffonia simplicifolia‚ a West African climbing bush with legumes. 5-Hydroxy L-Tryptophan (also called 5-HTP) is generally produced naturally in our bodies from tryptophan. Then‚ 5-HTP is synthesized into serotonin. However‚ if something inhibits the production of 5-HTP‚ like low tryptophan‚ our bodies won't get the serotonin we need. But that's where 5-HTP supplements like Progressive Labs' 5-Hydroxy L-Tryptophan come in; If serotonin production is a three step process‚ a 5-HTP supplement bypasses the first step and jumps right to second one by providing the 5-hydroxy L-Tryptophan that the first step would have produced. From there‚ serotonin production can continue.

5-HTP supplements have been used to treat a wide variety of conditions like depression‚ fibromyalgia‚ sleep disorders‚ and more.
