Caffeine is by far the most commonly used nootropic, consumed worldwide for its energy-boosting effects. For thousands of years1, caffeine has been used as a cognitive enhancer to improve attention, concentration2,3 and working memory4. Recent research has shown that caffeine has additional benefits as well, improving physical endurance5 and lowering the risk of dementia6, cancer7, and stroke8. However, too much caffeine can sometimes cause anxiety and jitteriness9, and that’s where L-Theanine comes in.
L-theanine is a less well-known nootropic, but is found in green tea and many common dietary supplements. On its own, L-theanine has been shown to improve learning and memory by modulating levels of neurotransmitters in the brain10, but its true potential shows when it’s combined with caffeine. The ratio of L-theanine to caffeine that we use to make Grove Ave Starter has been rigorously tested in numerous scientific studies, and has been shown time and time again to significantly improve cognitive performance and elevate mood11,12,13,14, without the anxiety and jitters caused by caffeine alone.
Echinacea is a plant native to North America that was widely used by Native Americans for its medicinal qualities15. More recent scientific studies have shown that echinacea extract has beneficial effects on your immune system, boosting the activity of several different types of cells that are integral for natural immune responses16. We included echinacea in this daily supplement to strengthen your body’s immune system so nothing can stop you from achieving your goals.
You’ve probably heard of vitamin C, an essential nutrient involved in many of your body’s metabolic functions which is found naturally in many types of fruits and berries. But, did you know that vitamin C is also good for your brain? Vitamin C is directly involved in the production of neurotransmitters, molecules that provide chemical signals in the brain17. In this stack, vitamin C is included as a daily booster for the function of your body and mind.
