L-Theanine is generally considered safe for most people when taken in appropriate doses. However, it is important to speak with a healthcare provider before starting any new supplement regimen, especially if you have a history of liver disease or are taking medications that may interact with L-Theanine.
Conclusion
L-Theanine is a natural amino acid that has gained popularity for its potential health benefits. While it is generally considered safe, individuals should be aware of the risks and side effects associated with taking L-Theanine.
