An Introduction to L-Theanine Drug Interactions
Even though
L-theanine (also known as just
theanine) is a natural product, it can potentially interact with some medicines. Some of these medicines that may lead to L-theanine drug interactions include:
L-Theanine Interactions Explained
The following sections explain in detail the potentially negative interactions that can occur when L-theanine is combined with any of the drugs listed above.
Blood Pressure Medications
Theoretically, combining L-theanine with a
high blood pressure medication could increase the risk of low
blood pressure (hypotension). Although this interaction could potentially be beneficial, it could also be dangerous (if blood pressure is lowered too much). Check with your healthcare provider before combining L-theanine with any
blood pressure medicine. It may be especially important to monitor your blood pressure when starting or stopping L-theanine or a blood pressure medication.
Stimulants
Theoretically, L-theanine could make stimulant medications less effective. This is less of a concern for stimulants used for non-medicinal purposes.
