The Science
Every ingredient earns its place. Here's the mechanism behind a shot that actually lasts the shift.
NeuroFactor™ — 100mg
NeuroFactor™ is the only clinically studied cognitive ingredient available in a shot format. It raises BDNF — brain-derived neurotrophic factor — by 143%, supporting the neuroplasticity and mental sharpness that carry you through the whole shift, not just the first hour.
L-Theanine — 200mg
An amino acid from green tea. Paired with caffeine it promotes an alert-but-calm state — the alpha-wave pattern associated with relaxed focus. This is why FieldShot doesn't come with the jittery edge of a straight energy drink. Smooth focus without jitters; it works with caffeine, not against it.
Rhodiola Rosea — 300mg
An adaptogen with data behind it on long-shift workers. Rhodiola cuts mental fatigue and extends the focus window past what caffeine alone delivers — the back half of the shift, when a normal energy drink would already be fading.
Natural Caffeine — 75mg
Caffeine blocks adenosine receptors, delaying the perception of fatigue. At 75mg you get a clean lift — alert, not anxious. That's half the caffeine of 5-hour Energy, enough to engage without sending you into overdrive.
Methylated B-Vitamins + Electrolytes
B6 and B12 are cofactors in ATP energy metabolism. We use the methylated, bioactive forms (P-5-P and methylcobalamin) so they're ready to work regardless of your MTHFR status. Electrolytes round it out with hydration support — ATP energy support and hydration in one.
Why no sugar
Sugar gives you 20 minutes of elevation and 90 minutes of payback. A sugar-free formula lets the caffeine and nootropics do the work without an insulin-driven crash pulling you back below baseline. That's the whole point of a functional shot — clean, sustained, no rebound.
