Raise your hand if you could use some stress relief. Yep! We thought so. What about sleep…are you struggling to get peaceful slumber at night? We hear you. How about mental clarity and focus? All of these things are something many Americans struggle with on a regular basis. Lack of rest, anxiety and even low immunity affect us all! L-Theanine is an amino acid that naturally occurs in black tea, green tea and even certain types of mushrooms. Amino acids are often referred to as the “building blocks” of proteins and they play a critical role in helping us feel our absolute best. Our bodies are not capable of producing theanine which is why many people incorporate it into their daily wellness routine. What are some of the benefits of Superior Labs 100% Natural L-Theanine?

  1. Provides Stress Relief:If you have ever sat down with a mug of hot tea, you know how relaxing it can be. Turns out, there’s some science to the reason you feel so restful and calm!

  2. Increase in Mental Focus:Why does it always seem like our minds start to wander when we need to complete an important task? From getting work done to studying for school, maintaining strong focus and concentration is key to being successful! L-Theanine has been shown to increase focus and improve brain function.

  3. Can help to Boost Immunity:This year, having a strong immune system has become the focus for many people around the world.

After all, the higher your blood pressure the more at risk you are for experiencing health issues in the future. High blood pressure puts extra strain on your arteries and heart.

That’s why it is so important to balance your blood pressure. L-Theanine may be beneficial for those who experience high blood pressure, especially when dealing with stressful situations. A study showed that L-Theanine helped to control blood pressure after performing certain mental tasks.
