L-Theanine is a calming and focusing non-dietary amino acid that is uncommon in food sources and is found primarily in green tea. It is most commonly used for its relaxing and mildly stimulating effects but has also been found to increase mood and focus, improve sleep quality and have other health promoting effects. Recommended dosage is 100-200 mg once or twice daily. There is hardly any evidence of side effects from the use of this supplement.

Suggested Stack:


  • Powerful Cognitive Enhancer
  • Strong Mood Booster
  • Energizing and Stimulating

L-Theanine and Caffeine are two highly effective compounds with a long history of use in different cultures around the world. On the one hand, L-Theanine is typically used for its relaxing, calming, and stress-reducing effects, along with its powerful antioxidant benefits. On the other hand, Caffeine is used for its energizing, mood-boosting, and stimulating effects. Combining the two compounds has some great results, which have been verified in scientific studies around the world.

Caffeine + L-Theanine capsules can be used to improve mood, boost cognitive performance, and to stimulate mental energy. There is also evidence that L-Theanine helps mitigate some of Caffeine’s potentially negative side effects. The recommended serving size is 1-2 capsules of 250 mg, once to twice daily. Side effects of too much Caffeine include nervousness, headache, tremor, spasms, palpitations, high blood pressure, insomnia, and indigestion. Do not exceed the recommended serving size.


L-Theanine is a fairly rare phytochemical and a non-dietary amino acid found primarily in a small number of mushrooms and in common tea,Camellia sinensis. For thousands of years, people in the East have used strong tea as a health-promoting and calming drink. Without knowing it, they were tapping into the benefits of L-Theanine. These include the ability to help reduce stress, improve mood and mental focus, boost your sleep quality, and promote a healthy circulatory system through its powerful antioxidant effects. [1]

Caffeine is even better known than L-Theanine.With coffee being the world’s most consumed drink, most people have a good understanding of Caffeine’s effects. It is energizing and stimulating, with noticeable improvements in mood and cognitive performance. The Caffeine compound is known as a purine alkaloid and is found predominantly in Coffea Arabica (the ‘coffee tree’), which is a dark green shrub that is indigenous to Ethiopia. [2]
