Caffeine + L-Theanine

Caffeine and L-Theanine are two compounds paired together in a popular dietary supplement. Caffeine is a naturally occurring stimulant most commonly associated with coffee and tea, while L-Theanine is an amino acid primarily found in the leaves of the tea plant.

The appeal of this supplement lies in combining the distinct biochemical effects of these two substances. The L-Theanine component is included to complement the experience typically associated with the caffeine component.

The combination of Caffeine and L-Theanine is primarily used to enhance cognitive performance and promote a state of alert relaxation. While the caffeine component provides increased energy, alertness, and improved reaction time, the L-Theanine is thought to modulate the experience by fostering a sense of calm and reducing the perception of stress.

A significant function of combining these two substances is to mitigate the less desirable side effects often associated with a high intake of caffeine. L-Theanine's balancing effect helps to smooth out the typical caffeine experience, aiming to reduce feelings of jitteriness, anxiety, and the post-stimulant crash.

Ultimately, the supplement is designed to deliver a cleaner, more stable form of focus and energy, allowing users to sustain concentration and mental clarity for extended periods.

Caffeine + L-Theanine supplement combination is generally well-tolerated and is often specifically intended to minimise the negative side effects of caffeine alone, such as anxiety, jitters, and elevated blood pressure.

However, because the supplement contains caffeine, adverse effects associated with high caffeine intake remain a possibility, including headache, nausea, upset stomach, dizziness, and insomnia, particularly in caffeine-sensitive individuals or at very high doses.
