3. L-Tryptophan
Supplemental nutrients can be purchased at many health stores. One type of supplement that some people take is l-tryptophan. Tryptophan is an important nutrient as it is actually a precursor to the release of serotonin.
The brain produces tryptophan naturally as a way to build serotonin amounts. The more tryptophan that you have, the larger the capacity you have to produce serotonin. Many people use l-tryptophan as a way to help manage their moods. Some people use it as a smart drug, this means they use it as a way to help them perform better in a social situation or during work situations.
The danger of this is that it can cause the body to produce too much serotonin. Many people do not even realize that this can happen. If you have been using l-tryptophan as a performance enhancer and continue to use it, you may end up with serotonin syndrome.
