Caffeine 100mg + L-Theanine

$9.99

Caffeine + L-Theanine supplements significantly improve performance, accuracy, and speed on cognitively demanding tasks. The synergistic effect of Caffeine and L-Theanine means improved energy, focus, and awareness.

Mercer’s Caffeine 100mg + L-Theanine provides natural focus and energy stimulant. Caffeine from Guarana is more potent than coffee beans, and as a stimulant, tends to increase dopamine levels which boosts concentration, energy, and focus. While L-Theanine (naturally occurring in green tea) has been found to enhance attention significantly.

Plus, B vitamins and Folic, essential for brain function, mental focus, and positive mood.

CAFFEINE 100mg + L-THEANINE 50mg are in just the right amounts to synergize perfectly, making their effect more powerful in improving mental focus and boosting energy.

This is one of the best caffeine supplements out there if you want to get some additional nutrients in. I don't get the heart flutters or the crash from this product. I'm a woman and I know it's for "men" but they don't really make one like this for us. I have ordered many times off of Amazon and now directly from their website. It's been a great experience every time!
