L-Theanine by Olympian Labs is a product meant to improve the general well-being of people, using ingredients that are completely natural, the main ingredient being an amino-acid extracted from green tea.
The US-based manufacturer began operating in the supplement market in 1992, building a name for itself through the transparency tactic it has employed, providing customers with full information on their products, encouraging them to provide feedback that gets published directly to their website and ensuring top-notch logistics.
L-Theanine is advertised as a “feel good” supplement, increasing the general well-being of consumers by supplementing energy levels, focus capacity and boosting the immune system. Used by some people as a replacement for coffee or caffeine-based products, L-Theanine seems like a well-needed boost in facing day-to-day activities in a more relaxed manner.
1) L-Theanine at a Glance
The active ingredient in L-Theanine is an amino-acid with the same name, extracted from tea leaves, particularly green tea. It has been commercialized as a supplement for over 50 years, although its effects are still being studied.
Theanine is proven to have psychoactive properties, crossing the blood-brain barrier with ease and acting in a similar fashion to caffeine, by reducing stress and improving people’s moods and cognition. It also increases dopamine levels, a chemical substance that functions primarily as a neurotransmitter.
There is evidence that L-Theanine also boosts the immune system; it might even make people happier, by stimulating the production of serotonin in humans, although this effect is still undergoing trials.
2) What Are L-Theanine Ingredients?
L-Theanine contains: L-Theanine(from green tea), Microcrystalline Cellulose (Plant Fiber), Rice Flour, Ascorbyl Palmitate, Magnesium Stearate, and Silica.
3) Does L-Theanine Work and it is Safe?
L-Theanine is the main ingredient found in Green Tea, a powerful antioxidant, and it is an amino acid. This product is marketed as a means to helping the body reduce problems such as those with the digestive tract and the urinary tract. Women will find it to diminish symptoms of PMS and reduce stress. Some individuals might also benefit from this product if low levels of anxiety kick in at unwanted times because it claims to calm the brain shortly after taking it.
The calming effects are also recommended for both children and adults alike if who have ADD or ADHD. To name a few more of the properties of L-Theanine, it is said to improve learning ability and concentration, control hypertension and support the immune system. That’s quite a list for something extracted from the humble Green Tea, but this product’s website mentions next to nothing about how L-Theanine works.
Furthermore, no studies have been posted on this site, regardless if they even exist in the first place. More information about other ingredients would have been helpful as well. L-Theanine has been linked to various types of side effects. These side effects include feeling dizzy, headaches that linger for several days at a time, and problems with the GI tract.

8) The Bottom Line – “Does it Work?”
While the product has a lot of advantages in theory, there is little evidence to support the claims that L-Theanine has the effects stated. The small amount of available testimonials, along with the fact that most of the effects are still being researched, point towards the idea that other supplements that are proven to perform as advertised are preferred.
There is, however, the undeniable advantage that L-Theanine is entirely natural. Also, Olympian Labs’ policy of ensuring full transparency for their customers, along with the 30 day money-back guarantee might encourage people to try this product, under the idea that not much could go wrong.
