Theanine is a great relaxing agent, meaning it will calm you down, but it won’t make you sleepy. Theanine also slightly stimulates the brain and may improve your attention, but to really get an intense focus, combine theanine with caffeine.
- What are the side effects of taking L-Theanine?
You shouldn’t feel any negative side effects when ingesting theanine. Some people have reported having an upset stomach after drinking too much green tea, but that is probably more because of the bitter taste profile of the beverage, rather than the contents themselves.
- Should I drink green or black tea?
If you decide to drink tea for its nootropic features and not for its taste, then you’re looking at a question that has two answers. While the effects of drinking tea will not be as intense as taking theanine in powder form, I’d recommend going with green over black tea, as it contains slightly more theanine. If you’re looking for a bit more caffeine, however, choose black tea instead.
- Why should I choose pure theanine and caffeine over tea?
Most studies have shown discrepancies in the L-Theanine to caffeine ratios in green and black teas, so you can never really know for certain how much of either compound you’re getting with a cup of tea. Measuring out powder takes the guesswork out of the equation, and you’ll end with similar results every time you decide to use the two substances together.
