Many people are looking for simple ways to boost their focus, memory, and productivity. That’s why nootropics, or “smart drugs,” are growing rapidly in popularity.

Nootropics are a class of natural or synthetic compounds that may improve your brain function. While hundreds of nootropic supplements are available, several beverages contain natural nootropic compounds

What’s more, other drinks boast ingredients, such as antioxidants or probiotics, that may support your brain function.

Green juice combines green fruits and veggies, such as:

dark leafy greens like kale or spinach
cucumber
green apples
fresh herbs, such as lemongrass

Green smoothies may also contain ingredients like avocado, yogurt, protein powder, or bananas to add creaminess and nutrients.

While the brain-boosting potential of green juices or smoothies depends heavily on the ingredients, these drinks are often rich in vitamin C and other helpful antioxidants.

Drinking nootropic beverages may seem like an easy way to support brain health.

However, although some of these drinks may help boost brain function, high quality evidence is lacking to support drinking any of these beverages to improve focus, performance, or memory.

Regardless, these drinks offer other health benefits and may be worth trying to see whether they work for you.
