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.
L-Theanine contains: L-Theanine(from green tea), Microcrystalline Cellulose (Plant Fiber), Rice Flour, Ascorbyl Palmitate, Magnesium Stearate, and Silica.
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.
The recommended dose for this supplement is one capsule each day. There is little evidence of any negative side-effects occurring due to the consumption of this product, but the product is still undergoing trials on humans.

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.
