L-Theanine

Multiple clinical trials demonstrate that combining caffeine with L-theanine produces superior cognitive benefits compared to either alone. A meta-analysis of 15 studies found the combination significantly improved reaction time, attention accuracy, and mood. L-theanine helps maintain focus while smoothing caffeine's stimulant effects.

Lion's Mane Mushroom

In a 16-week clinical trial, adults with mild cognitive concerns who took 3g of Lion's Mane daily showed significant improvements in cognitive function compared to placebo. Multiple studies suggest Lion's Mane may support mental clarity through its unique ability to stimulate nerve growth factor production.

Cordyceps Mushroom

In a clinical trial, active adults who supplemented with Cordyceps militaris for 3 weeks showed significant improvements in VO2max compared to placebo. Clinical research shows Cordyceps supplementation significantly improves oxygen utilization during physical activity.

Melatonin

A meta-analysis of 19 clinical trials found that melatonin significantly reduced the time it takes to fall asleep and increased total sleep time. Research suggests taking melatonin 2-3 hours before bedtime may be more effective than taking it immediately before bed.
