Caffeine + L-Theanine

This standardized supplement provides 100mg of pure caffeine combined with 200mg of L-theanine per capsule, creating a balanced nootropic formula designed to support mental performance and clean energy.

L-theanine is a natural amino acid found in tea leaves that promotes relaxation without causing sleep and helps balance the negative effects of caffeine.

Together, these compounds form one of the most popular nootropic stacks supporting cognitive function and sustained alertness. This formula is ideal for adults seeking mental clarity support during work or study. Take 1 capsule 1-2 times daily as part of your daily wellness routine for sustained cognitive support throughout the day.
