Marketed for focus, but the ingredients that matter most for attention are significantly underdosed. **Phosphatidylserine** — the compound with the strongest evidence for cognitive performance under stress — provides 50 mg per serving against a studied range of 300–800 mg. **DHA**, the omega-3 most linked to brain function, delivers 50 mg versus the 1,000–3,000 mg used in research.

Your B vitamins (B1, B2, B3, B6) are generously dosed, which supports general energy metabolism but doesn't directly address focus or attention. **GABA** at 100 mg hits the low end of its supplemental range, and **Lemon Balm** at 200 mg falls short of the 300–600 mg studied for calming effects.

The liquid format may absorb faster, but that advantage means little when the core attention-support compounds are at 6–17% of their studied doses. The gap between what's on the label and what the research actually used is wide.
