L-theanine For OCD: Supplement Benefits

L-theanine is a natural amino acid that has been shown to reduce anxiety and improve cognitive function. Studies have also found that L-theanine can be helpful in treating OCD symptoms. Learn more about the potential benefits of L-theanine for OCD and how to take it safely.

Key Takeaways

  • L-theanine may help to reduce OCD symptoms by increasing levels of GABA, a neurotransmitter that plays a role in relaxation.
  • L-theanine may also help to improve cognitive function and reduce anxiety, which can be beneficial for people with OCD.
  • While more research is needed, L-theanine is generally considered safe and well-tolerated, and it may be a helpful supplement for people with mild to moderate OCD.

Whether you personally know of someone who suffers from OCD or you’ve heard it thrown around as slang, chances are you’re familiar with the term.

But not many, aside from those who suffer from it, actually know what it means or how to manage it. That’s because only 1% of the world’s population is known to suffer from this condition. While that seems minor, this adds up to nearly 70 million people who are affected. (Source)

OCD is a well-known acronym for obsessive-compulsive disorder, a condition in which a person experiences recurring, uncontrollable thoughts, or obsessions and/or participates in repetitive behaviors, a.k.a compulsions.

This could look like an extreme fear of germs, fear of forgetting or misplacing items, or a strong desire for perfect order/extreme neatness. It may also include accompanying compulsions that align with obsessive thoughts, such as repetitive hand washing or compulsive cleaning and organizing. (Source)

Unfortunately, the cause of OCD is still not known but it has been determined that there are genetic factors that increase the likelihood of developing OCD as well as the presence of childhood trauma and biological differences in the brain. (Source)

While there are many treatments currently available to manage this disorder ranging from psychotherapy to medication to herbal supplements, the effectiveness depends on the individuals and the severity of the condition.

As you can imagine, OCD can inflict many negative impacts on one’s mental well-being and medication sometimes exacerbates these impacts. In mild cases of OCD, nutritional supplements, such as L-theanine, may provide a more beneficial impact without all the negative side effects. In fact, many combination therapies are already utilizing L-theanine.

However, when considering nutritional supplements for OCD symptom management, the quality of the supplement and the trustworthiness of the brand are of the utmost importance. Enter Human Tonik, a supplement company at the forefront of the health and wellness sector.

Human Tonik offers a variety of health and wellness supplements including L-theanine, along with third-party testing and full ingredient transparency. Human Tonik does not utilize proprietary blends so you always know exactly what and how much is in their products.

Understanding L-theanine

L-theanine Powder and Tea

Aside from the possibilities of L-theanine for OCD symptoms management, L-theanine has become quite a popular supplement over the recent years. It touts many potential health benefits ranging from improved sleep, relaxation, and cognitive performance, many of which is why it may be helpful with OCD in the first place.

However, to understand how L-theanine benefits those with OCD, you first need to understand L-theanine. Let’s dive in.

Definition And Properties

L-theanine is one of the 9 non-essential amino acids, a building block for protein. It is considered “non-essential” because our body makes L-theanine on its own and we don’t require it from food like we do the other 11. However, you can get L-theanine from tea, specifically green and black tea leaves.

While this amino acid is not considered essential, it has been associated with a variety of health benefits, such as reducing anxiety, improving sleep, and boosting mental clarity and focus, which is why it’s become a popular supplement in the first place. In fact, L-theanine from green tea leaves has been used extensively in traditional Chinese medicine. (Source)(Source)(Source)

It’s hypothesized that L-theanine provides these benefits by increasing alpha waves in your brain to help your mind relax without causing drowsiness.

This can not only help you chill out, but it can also ease your mind to allow it to focus on other, more important things. When taken at the proper time, it may even help you to wind down and prepare your body for more restful sleep, which also provides tremendous benefits to our mental health. (Source)

In addition to teas, you can find L-theanine in coffee and some varieties of mushrooms. While there are many purported benefits of taking L-theanine, this supplement is still being studied as there remains limited research regarding its effects on our health and mental wellness.

Always speak with your doctor or healthcare provider before adding an L-theanine supplement to your routine, especially if you are considering taking it for OCD.

L-theanine And OCD

Unfortunately, OCD is not a curable disorder. But with the proper tools, those affected may be able to better manage their symptoms which can help to improve quality of life. While there are many successful medical interventions for OCD, some may wish to pursue a more natural path.

L-theanine has been explored for its potential benefits in managing the symptoms of OCD. Researchers hypothesize that it may help people afflicted with this condition in several ways, including increasing the neurotransmitters GABA and serotonin in the brain. Gamma-aminobutyric acid (GABA) helps to provide a calming effect while serotonin helps with mood regulation.

Additionally, L-theanine may affect our brain waves. This amino acid is believed to increase alpha waves in our brain, which are associated with relaxation as well as mental alertness.

While the current literature on L-theanine for OCD is limited and research studies are typically conducted on small population groups, the outcomes are promising.

For example, a study published by the Journal of Clinical Psychiatry provided 50 individuals who suffered from OCD with either 200 mg of L-theanine twice a day or a placebo. By the end of the study, those who were given L-theanine experienced a significant reduction in OCD symptoms compared to the placebo group. (Source)

Additionally, another study conducted on 40 individuals suffering from OCD provided 400mg of L-theanine with the same results. While these results are promising, both of these studies were conducted on small sample sizes, and further research utilizing larger population groups is warranted. (Source)

Overall, the research suggests that L-theanine may be a helpful addition in doses of 200-400 mg for symptom management in those with mild to moderate OCD.

Other Benefits Of L-theanine

Brainstorm and emotive cognitive concept

In addition to potentially mitigating OCD symptoms, L-theanine may provide other health benefits including reducing stress and anxiety and providing enhanced cognitive function.

Anxiety And Stress Reduction

While sipping on a hot cup of tea can provide its own calming effects, the L-theanine in tea may be the real reason you feel your stress and anxiety melting away as your cup grows empty.

In fact, a review that included five randomized controlled trials of over 100 participants found that four of the trials were able to successfully link L-theanine supplementation with improvements in stress and anxiety levels. (Source

These studies linked the likely reason behind L-theanine’s calming effects to its alterations in neurotransmitter levels; however, the exact mechanism remains unknown, and further research is still underway.

In addition to reducing stress and anxiety, L-theanine may also be helpful in promoting restful sleep. While this could be related to the calming effect it has, it’s safe to say many of us sleep a lot better when we aren’t struggling with high stress or anxiety.

L-theanine has strong potential to be utilized as a safe, natural alternative to sleep medication because of its anxiolytic effects. (Source)

Cognitive Enhancement

L-theanine may also be helpful in improving focus and cognition.

For example, one study found that 97 mg of L-theanine combined with 40mg of caffeine helped to increase focus and attention in a group of young adults completing demanding tasks. (Source)

Another study on middle-aged and older subjects in Japan found that L-theanine may contribute to improving attention and enhancing working memory and executive functions. (Source)

This is likely related to the same effects L-theanine has on sleep. It’s believed the increase in alpha brain waves is to thank for the increased alertness, focus, and creativity, while also enhancing relaxation. (Source)
