Formula Quality

Inclusion of melatonin and 5-HTP indicates a formula designed for nighttime rest, which creates a direct conflict with the goal of maintaining daytime mental focus. Although Suntheanine is included at an effective 200mg dose, its potential for promoting calm focus is likely overshadowed by the sedative effects of the other ingredients.

Users seeking to improve concentration during demanding tasks may find the chewable format convenient, but the physiological effects are more suited for relaxation and sleep. The overall composition lacks ingredients that support alertness or cognitive processing speed.
