F Goal FitA- Strength of SupportF CoverageD Formula Quality

Sustained mental focus is compromised here by the inclusion of melatonin and 5-HTP, which are specifically designed to facilitate rest and sleep. Although the 200mg of Suntheanine provides high-quality L-theanine to promote calm, its focus-enhancing properties are likely diminished by the sedative effects of the formula.

The larger bottle size and chewable format provide convenience for regular use, but the physiological outcomes are geared toward relaxation. This selection is better suited for evening use than for tasks requiring sharp attention or alertness.
