ADHD and L-Theanine: A Natural Approach to Focus and Relaxation

I've talked a few times about ADHD, because I love it. There are so many strengths to having ADHD - creativity, energy, engagement - and I hope we work towards celebrating this type of brain, a lot more. Rather than a brain imperfection, sometimes societal structures are just not set up for neurodiverse people. When this happens, the traits of 'inattentive, hyperactive, impulsive' become a problematic side of the same ADHD characteristics (just in different contexts).

One downside of ADHD that most people can agree on, regardless of which side of the coin we're looking at, is an inability to relax and wind down. Everyone needs to have a quiet brain time, especially the busiest of brains, so there are a few ways we can do this.

There are conventional treatments such as stimulant medications and behavioural therapies play a vital role in managing symptoms to help with focus. Frustratingly, the medical approach to relaxation is to ensure that the medications have worn off in time for rest.

Lots of people now seek additional support through diet, lifestyle, and natural supplements. There are a lot of ways to do this for ADHD, and I have written about it a few times if you'd like a read (just search ADHD on the blog).

One supplement gaining a bit of attention is L-theanine. This is a naturally occurring amino acid found in green tea. Known for its calming effects, L-theanine may offer benefits for individuals with ADHD, helping to enhance focus while reducing stress and anxiety. But how does it work, and is it safe to use alongside medication? Let’s take a closer look.

What Is L-Theanine?

L-theanine is an amino acid predominantly found in tea leaves, particularly in green and black tea, and certain types of mushrooms. Unlike other amino acids, L-theanine does not contribute to protein synthesis in the body but instead influences brain chemistry.

Research suggests that L-theanine can cross the blood-brain barrier and directly impact neurotransmitters, promoting a state of 'relaxed alertness'. This unique effect makes it a promising natural supplement for ADHD management.

How Can L-Theanine Help with ADHD?

L-theanine’s benefits stem from its ability to modulate brain activity, particularly through its impact on neurotransmitters such as gamma-aminobutyric acid (GABA), dopamine, and serotonin. Here’s how these effects may support individuals with ADHD:

1. Promotes Relaxation Without Drowsiness

ADHD is often associated with heightened levels of stress and restlessness. L-theanine enhances the production of GABA, a calming neurotransmitter that helps reduce feelings of anxiety and stress. Unlike sedatives, L-theanine does not induce drowsiness, making it beneficial for promoting relaxation while maintaining alertness.

2. Enhances Focus and Attention

One of the primary challenges for individuals with ADHD is maintaining attention and focus. Studies suggest that L-theanine, particularly when combined with caffeine, can improve sustained attention and reduce mind-wandering. This may be particularly useful for students or professionals who need to stay on task for extended periods.

3. Improves Sleep Quality

Sleep disturbances are common among individuals with ADHD, often exacerbating symptoms of inattention and impulsivity. L-theanine has been shown to improve sleep quality by enhancing alpha brain wave activity, which is associated with relaxation (remember, relaxation not sedation! Even insomnia is mostly about anxiety, so could work there too).

A better night’s sleep can also lead to improved cognitive function and emotional regulation during the day.

4. Supports Dopamine Regulation

Dopamine is a key neurotransmitter involved in motivation, pleasure, and focus—areas where individuals with ADHD often struggle. L-theanine helps modulate dopamine levels, which may contribute to improved mood and concentration.

Is L-Theanine Safe to Use with ADHD Medication?

A common concern for those considering natural supplements is their safety alongside prescribed ADHD medications, such as methylphenidate (Ritalin) or amphetamine-based treatments (Adderall, Vyvanse). Fortunately, research suggests that L-theanine is generally safe and does not interact negatively with these medications.

L-theanine’s mechanism of action differs from stimulant medications, meaning it does not compete or interfere with their function. In fact, some individuals find that L-theanine helps to mitigate the jittery side effects of stimulant medication by promoting a sense of calm without reducing the medication’s effectiveness.

That said, while L-theanine is well-tolerated in most people, it’s essential to consult a qualified naturopath, nutritionist and the professional who prescribed your medication, before adding any supplement to your routine. This ensures appropriate dosing and consideration of individual health needs.

How to Take L-Theanine for ADHD Support

L-theanine is available in various forms, including capsules, tablets, and naturally in green tea. The best form and dosage will depend on individual needs and existing treatments.

• Green Tea: Contains natural L-theanine but also caffeine, which may or may not be beneficial depending on the individual.

• L-Theanine Supplements: Typically available in doses ranging from 100mg to 400mg. Most studies suggest an effective dose of 200-400mg per day.

• Combination with Caffeine: Some supplements pair L-theanine with caffeine in a 2:1 ratio (e.g., 200mg L-theanine with 100mg caffeine) to enhance focus without causing overstimulation. This can be a good option for those trying to cut down on coffee (indigestion, cost) but still want the alertness.

Since every individual with ADHD has unique needs, working with a health professional can help

determine the optimal approach.

The Importance of a Holistic Approach

While L-theanine may offer valuable support for individuals with ADHD, it should be viewed as part of a broader strategy rather than a standalone solution. A holistic approach to ADHD management includes:

• A Balanced Diet: Nutrient-dense foods rich in omega-3 fatty acids, protein, and essential vitamins support brain health.

• Regular Exercise: Physical activity helps regulate dopamine and improve focus.

• Mindfulness and Stress Management: Techniques such as meditation, deep breathing, and yoga can further enhance relaxation and focus.

• Professional Guidance: A qualified nutritionist or naturopath can tailor recommendations to individual needs, ensuring safety and effectiveness.

L-theanine is a promising natural supplement that may help individuals with ADHD by promoting relaxation, enhancing focus, and improving sleep quality. Its ability to work synergistically with ADHD medications makes it a potential complementary tool for managing symptoms. However, as with any supplement, it’s crucial to consult a qualified healthcare professional before use.

If you or someone you know is exploring natural ways to support ADHD, consider seeking professional advice to create a comprehensive, individualised plan that incorporates the best of both conventional and natural approaches.
