Ever heard of the Limitless movie (or the Netflix show for that matter)? It’s where Bradley Cooper’s character, Edward Morra, found a nootropic drug - NZT-48 - which turned him from a struggling writer into a brain super power (like 4-digit IQ and a memory that remembers practically EVERYTHING).
So first of all - what is “nootropic”?
According to Healthline, nootropics are natural or synthetic substances that can be taken to improve mental performance in healthy people. 
They’re also known as “smart drugs” and “cognitive enhancers” because they take executive functions, memory, creativity and other cognitive functions to a whole another level. Essentially, nootropics help you gain optimal function for all things brainy!
Second of all - why are we talking about Limitless and nootropics?
Let’s just say that this Limitless drug exists IRL, except that instead of a pill, it’s a naturally-occurring amino acid.
And it also starts with the letter L.
Commonly found in tea leaves and some mushrooms, L-theanine is an amino acid that brings about a trifecta of optimal brain activity:
The good news doesn’t stop there. L-theanine has been found to contain ZERO trace of toxicity, dependence and tolerance. This simply means that there’s no need to worry about going overboard - you can take large doses and NOT suffer from any adverse effects.
If you're keen for some L-theanine fix, you can go grab yourself a cup of green or black tea. There are also supplements available in retail or online.
If you’re feeling so pumped about L-theanine that you just want to go For a green tea run RIGHT NOW, wait 'til you get to the best part... the health benefits!
Studies also show that tea is your best bet in dealing with high anxiety levels.  In fact, a series of five randomised-controlled trials prove that L-theanine reduces stress and anxiety during difficult situations.  Another study shows that our favourite amino acid also promotes relaxation sans drowsiness .
During stressful situations, our body produces stress hormones such as cortisol and corticosterone. These hormones prevent our brain from thinking clearly.
Thanks to L-theanine, which reduces the level of these hormones, we can think properly amidst stress and anxiety. A study conducted in 2013 showed that a combination of L-theanine and caffeine (more of this later) gave a group of young people increased “subjective alertness” and improved cognitive performance as they went through challenging activities. 
Not only can L-theanine reduce anxiety, it also boosts our focus, attention, memory and learning. Studies have found that L-theanine enhances these cognitive functions while increasing attention span and reaction time among anxious people. 
Studies have also found that L-theanine strengthens our immune system. Specifically, a research showed that it could steer us clear of upper respiratory tract infections.  L-theanine could also ease intestinal tract inflammation. 
Now that we know why L-theanine is called a smart drug, many have vouched for its effects when combined with - wait for it - caffeine.
Apparently, L-theanine has a powerful synergistic relationship with caffeine. Not only is the amino acid just as effective as caffeine when it comes to heightened attention and focus, it also amplifies caffeine’s stimulant properties while getting rid of its infamous downsides - anxiety, increased blood pressure, and jitters.
Here are some of the recent studies saying this is so:
L-theanine is a relatively safe nootropic that brings about a trifecta of optimal cognitive function. Because of its natural properties, L-theanine helps relieve stress and anxiety, boost focus and attention, helps you concentrate and become more creative, and strengthens your immune system. When mixed with caffeine, you get the positive effects of caffeine - amplified - and without its side effects. If you're sick of caffeine induced anxiety, jitters and increased blood pressure, the L-theanine-caffeine power duo is perfect for you!

Urinary Tract Infection is common among women throughout the world. It's caused by many factors, including hygiene, contraceptives, and certain health conditions. Luckily, there are various ways to treat and prevent UTI.
