6 nootropics that make your brain limitless

4. L-Theanine

L-theanine is an amino acid found in green tea, black tea and one type of mushroom. This amino acid has a pretty unique ability that makes it a popular nootropic. It improves your focus and attention while also making you feel relaxed.

More specifically, L-theanine creates several fascinating reactions in your brain. It increases levels of calming brain chemicals like GABA, serotonin and dopamine. It decreases levels of excitatory brain chemicals that make you feel stressed. Plus, it encourages alpha brain waves, which are the brainwaves associated with being awake and alert but also relaxed. Although, you should know that a lot of research shows L-theanine’s brain benefits are better when combined with caffeine.

L-theanine can also improve the quality of your sleep, which means it will leave you feeling rested, energized and on top of your game — the goal of any nootropic experimenter.
