Can you take L-theanine and alcohol together? 

Yes, you can take L-theanine and alcohol together. The combination is actually beneficial for you to some extent. L-theanine is an amino acid that your body does not produce on its own. 

This amino acid can help enhance your mood and sleep patterns because of its effects on some excitatory monoamine neurotransmitters in your brain, like serotonin, dopamine, etc. 

Although excessive use of anything is injurious to health, L-theanine and alcohol do go well together and the concomitant use holds some positive outcomes. Let’s talk about them. 

What are the benefits of taking L-theanine and alcohol together? 

L-theanine and alcohol together can be beneficial for you in a number of ways. These include:

  • Protects your liver from alcohol-induced damage
  • Decreases free radicals
  • Reduces the effects of alcohol hangover 
  • Decreases your alcohol tolerance 

Protects your liver from alcohol-induced damage

Almost everyone is aware of the fact that alcohol is heavy on your liver and long-term use of alcohol is linked to a number of liver diseases, like fatty liver, cirrhosis, etc. 

This is because alcohol is primarily metabolised by the liver. L-theanine actually helps relieve the burden on your liver and enhances the metabolism of alcohol (1). 

This causes less liver damage. In fact, several research studies have reported that the use of L-theanine with alcohol, in the long run, can protect your liver from severe damage. 

Decreases free radicals

Alcohol consumption is highly responsible for the production of free radicals in your body. Free radicals are harmful to your body as they give rise to a number of problems like cancer, early aging, gene mutation, etc. 

L-theanine actually helps kill these free radicals as this amino acid is antioxidant in nature. That’s how your body does not end up having a lot of free radicals as a result of alcohol consumption. 

Reduces the effects of alcohol hangover

L-theanine counteracts the effects of alcohol because of its chemical nature and how it works in your body. It is actually used by a lot of people before or after drinking alcohol to prevent hangover effects. 

Decreases your alcohol tolerance 

Alcohol tolerance builds when you continue to drink large proportions each day and your body slowly starts getting used to it. This tolerance makes you drink more to achieve that ‘drunk’ effect or you can say that you end up needing more alcohol to get under the influence. 

L-theanine counteracts that and reduces your alcohol tolerance. You start drinking less and get drunk just after a few drinks. This is actually a good approach to treating alcoholism. 

Final words

L-theanine and alcohol can be consumed together, and the amino acid can actually help you with the negative effects of alcohol. However, it is generally recommended to cut back on alcohol as much as possible. 

If you are struggling with alcohol addiction, you should seek professional help. Long-term use of alcohol and other medications can lead to dangerous health risks. 

It is also important to note that not all supplements can be beneficial to pair with alcohol. Some supplements, such as 5HT supplements, can cause nerve-racking side effects when paired with alcohol. So, make sure you discuss drinking alcohol with supplements with your provider.

L-theanine, on the other hand, can also be taken with antidepressants and antipsychotics. Just make sure you discuss the use of supplements with your doctor if you are on other prescription medications.
