The amino acid that’s commonly found in green tea and supplements, has been shown to benefit the body and mind in various ways. From gut health to mental alertness. And even – enhanced sports recovery.
L-Theanine does this by stimulating brain activity and preventing the onset of common infections by increasing white blood cell count – strengthening your defences.
Furthermore, by reducing oxidative stress that builds up during and after exercise, means you’ll be able to train more frequently – all thanks to l-theanine supplementation.
Benefits of L-Theanine on Reducing Inflammation
I’m sure you’ve felt it at one time or another. After a heavy training session, your body aches and swells, and there seems to be pain all over. Sometimes lasting for days.
This, my friend, is partly down to inflammation – an overlooked symptom of exercise and a stress-induced lifestyle. And believe it or not, inflammation can cause a number of health issues to arise if left unattended – not only aches and pains after exercise.
L-Theanine has been shown to reduce oxidative stress in the body when used continuously. It works to enhance your body’s ability to regulate inflammation – flushing out toxins from your body.
Benefits of L-Theanine on Inflammation:
- Faster recovery – By lowering inflammation, you’ll allow your body to flush out unwanted toxins that build up from exercise and stress. This will enhance your recovery significantly. L-theanine does this as it contains antioxidants which lower inflammation throughout the body.
- Increased immunity – L-Theanine has been shown to increase white blood cell count, which is the main defence in your body that helps to fight off illnesses and infections. The more white blood cells you have, the stronger your immunity will be – which further helps muscle and cell recovery.
Other benefits of L-Theanine Supplementation:
- Better cognition – L-Theanine, in some cases, is known as a nootropic. It can help your mind to work faster – increasing focus by stimulating the activity of GABA gamma-Aminobutyric acid. GABA is a neurotransmitter linked to better cognition.
- Reduced stress – While coffee my give you a short term buzz. L-theanine on the other hand, works to energize your body without causing anxiety to rise – or a large spike and crash in energy levels. This is partly in the way that l-theanine increases serotonin levels, helping you to be focused, yet relaxed.

Study on l-Theanine and Reduced Inflammation:
As for the study which tested L-theanine’s effects on lowering inflammation. A group of researcher tested 20 members of the Polish rowing team. The study lasted 6 weeks while using 150 mg of L-theanine supplementation daily.
At the beginning of the study, they asked the rowers to complete a 2000m rowing test while measuring stress levels, inflammation biomarkers, along with standard blood tests etc.
Then, the rowers used l-theanine daily for 6 weeks while carrying on with normal daily activities. At the end of the 6 weeks, the rowers completed a final test – again, 2000m monitored rowing.
It was found that inflammation was significantly reduced. This was due to the absence of IL-10 (a cytokine responsible for lowering inflammation). Which then highlights that l-theanine worked as a buffer against the onset of inflammation in the first instance – preventing the release of IL-10.Subsequently, because IL-10 was decreased, IL-2 to IL-09 were, on the other hand, increased. These cytokines (IL-2 to IL-09) are responsible for increased immunity in the body by multiplying white blood cell count. (I)
To summarise; thanks to the lowered amount of IL-10, a rise in other cytokines were allowed to flourish. Which then points to the fact that l-theanine does in fact, lower inflammation, whilst increasing immune health throughout the body.
How Much Theanine To Lower Inflammation?
As we can see from the above study, using 150 mg daily for 6 weeks has been shown to lower inflammation while increasing immune health. This dose recommendation is a good place to start if you want to see results in faster muscle repair post-exercise.

Sport Nutrition Expert Recommendation?
L-Theanine, whether you get it from tea or as a supplement, I highly recommend it to anyone who wants to lower stress, inflammation, or even oxidative stress after exercise – while increasing immune health.
Furthermore, l-theanine can also help to regenerate mental energy post-exercise. It’s been studied that using as little as 50 mg of l-theanine after a workout can reduce mental fatigue by a massive 50% – see the full article here.
As for increasing recovery by lowering inflammation, using 150 mg per day consistently has been shown to be highly beneficial for active people.
