Coffee is one of the most popular drinks in the world, and for good reason. It’s a great way to start your day and give you a much-needed energy boost. But did you know that there is a way to make your coffee even better? By adding L-theanine to your cup of joe, you can experience a range of benefits that will leave you feeling even more energized and focused.

L-theanine is a natural amino acid that is found in tea leaves and certain mushrooms. When consumed with caffeine, L-theanine has been shown to have a range of positive effects on the mind and body. Here are just a few of the benefits:

  1. Increased Focus and Alertness: L-theanine helps to increase alpha waves in the brain, which are associated with a state of relaxed alertness. This can help you to stay focused and alert throughout the day, without the jitters or crashes that can come with caffeine alone.
  2. Reduced Anxiety: L-theanine has a calming effect on the mind, which can help to reduce anxiety and stress. This is especially helpful for those who may experience jitters or nervousness after consuming caffeine.
  3. Improved Sleep: L-theanine has also been shown to improve sleep quality, allowing you to wake up feeling refreshed and energized.

Now that you know the benefits of L-theanine, you may be wondering how to incorporate it into your daily routine. That’s where Krios Coffee comes in. Our deliciously smooth medium roast coffee is infused with carefully selected vitamins and adaptogens, including L-theanine.

Don’t just take our word for it, though. Numerous studies have been conducted on the benefits of L-theanine when combined with caffeine. For example, one study published in the Journal of Functional Foods found that participants who consumed a combination of L-theanine and caffeine showed improved cognitive performance and reduced mental fatigue compared to those who consumed caffeine alone.

Another study published in the Asia Pacific Journal of Clinical Nutrition found that L-theanine can help to reduce blood pressure and heart rate, which can be beneficial for those with hypertension.

In conclusion, adding L-theanine to your coffee can have a range of positive effects on your mind and body, including increased focus and alertness, reduced anxiety, and improved sleep quality.
