Austin’s Functional Fuel Co. is entering the RTD energy space with POW! Energy Drink, a zero-sugar, 5-calorie can built around focus and clean energy. The formula leads with 250mg of Cognizin® citicoline alongside 200mg caffeine and 200mg L-theanine, a triple-threat combination that’s become a recognizable stack in the better-for-you energy category.
POW! Energy Drink doesn’t cut the Cognizin® dose. Kyowa Hakko’s 250mg clinical threshold is exactly what’s in every can, backed by published trials on attention and accuracy. This is what a real nootropic RTD looks like.
Citicoline has found a growing home in RTD beverages as consumers demand more functional return from what they drink. Cognizin® is Kyowa Hakko’s branded, clinically studied form of citicoline, and POW! uses it at the research-supported 250mg dose. That’s a meaningful spec for an RTD, where sub-clinical nootropic doses are common.
POW! Action-Packed Labeling, Action-Packed Formula
The packaging makes an equally strong statement: POW! channels 1960s comic book aesthetics, complete with halftone dot patterns, explosion-style lettering, and a back panel structured as a three-panel comic strip. One character delivers what may be the most self-aware ingredient callout in the RTD space: “It’s my lack of Cognizin, isn’t it?” The brand clearly knows its audience and leans into the narrative with intent.
POW! Energy is manufactured in Austin, TX and currently available in three flavors: Thunder Punch, Apple Bomb, and Blue Razz, with a Variety Pack for sampling all three. Let’s get into the formula, but first, sign up for PricePlow’s news alerts so you don’t miss a beat on any Cognizin®-based news:

POW! Energy Drink Ingredients
Each 16 fl oz can provides:
-
Citicoline (as Cognizin®) – 250mg
Cognizin® is a patented form of Citicoline (CDP-choline), a compound the body uses to synthesize phosphatidylcholine, one of the primary phospholipids in brain cell membranes. It also supplies choline for acetylcholine production, the neurotransmitter most associated with learning and focused attention. When consumed orally, citicoline breaks down in the gut into choline and uridine. Choline is directed toward brain structural support and neurotransmitter synthesis, while uridine crosses the blood-brain barrier and gets reassembled into CDP-choline for ongoing membrane maintenance.[1]
That structural role is only half the picture. Research using phosphorus magnetic resonance spectroscopy found that citicoline supplementation elevated phosphocreatine levels in the frontal lobe’s anterior cingulate region, a measurable sign of improved bioenergetics and enhanced phospholipid membrane integrity in areas directly tied to executive function, working memory, and sustained attention.[2]
POW! matches Cognizin® to the exact dose studied in the clinical literature. In a double-blind, randomized, placebo-controlled trial in healthy adult women, 250mg of daily citicoline for 28 days produced significantly fewer omission and commission errors on a sustained attention task compared to placebo, with results matching those seen in the 500mg group.[3] In plain terms, participants responded more accurately and filtered out distractions more effectively, and attentional focus translated into measurable output rather than a vague “brain health” gesture.
Cognizin® Citicoline is dubbed the The Brain Choline not just because it provides choline, but because it also supplies cytidine, which is also needed for the synthesis of phosphatidylcholine
Cognizin® is Kyowa Hakko’s patented, fermentation-derived form of citicoline, and it’s the ingredient form used across the clinical research cited here. That matters because generic CDP-choline sources rarely appear in the published human trials; the Cognizin® pedigree is part of what gives this dose claim real footing.
In the context of POW!, citicoline works differently than caffeine and L-theanine do. Those two ingredients handle the arousal and smoothness side of the equation. Citicoline addresses the underlying cognitive substrate: membrane phospholipid availability and acetylcholine synthesis. Caffeine may sharpen alertness, but citicoline gives the brain the structural and biochemical materials to help sustain attention under load. The combination is additive by design, and at these doses, each ingredient earns its place.

Caffeine – 200mg
Caffeine at 200mg is a well-researched, practical dose for supporting alertness, focus, and physical output. Its primary mechanism is blocking adenosine receptors in the brain, reducing the perception of fatigue and keeping the central nervous system primed for both cognitive and physical demands. The International Society of Sports Nutrition identifies 3mg to 6mg per kilogram of body weight as the effective performance range, with benefits extending to muscular endurance, movement velocity, strength, and a wide range of aerobic and anaerobic actions.[4] At 200mg, most adults fall comfortably within that window.
On the cognitive side, a broad review of caffeine’s effects confirmed improvements in reaction time, vigilance, accuracy, and mood at moderate doses, making it a reliable option for knowledge workers, gamers, and anyone managing extended mental demands.[5] For the physical side, a meta-analysis of 1RM and vertical jump studies found statistically significant improvements in upper body strength and muscle power with caffeine ingestion, supporting its value beyond just endurance contexts.[6]
Paired with 200mg L-theanine, the combination should smooth caffeine’s stimulant edge and support focused, sustained output. Alongside Cognizin® citicoline, caffeine helps combat tiredness while citicoline addresses the underlying cognitive substrate: membrane phospholipid availability and acetylcholine synthesis. Each ingredient works a different angle, and together they cover the stack from multiple directions.
POW! calls out a novel caffeine source on the label, though specific details haven’t been disclosed at launch. We’ll update this article as that information becomes available.
-
L-Theanine – 200mg
L-Theanine (γ-glutamylethylamide) is an amino acid found almost exclusively in tea leaves. It crosses the blood-brain barrier and influences GABA, glutamate, and dopamine activity in ways that support relaxed focus without sedation. The most direct evidence of that effect is alpha wave generation: research showed 50mg to 200mg oral doses produce alpha activity in the occipital and parietal regions within 40 minutes of ingestion, a recognized marker of calm, alert wakefulness without drowsiness.[7]
That relaxation mechanism is what makes the caffeine pairing effective. Caffeine raises alertness by blocking adenosine receptors but can also amplify sympathetic arousal and increase self-reported tension. Theanine counterbalances that edge. In a placebo-controlled crossover study, the theanine-caffeine combination outperformed caffeine alone on working memory reaction time, sentence verification accuracy, and mental fatigue ratings, with participants also reporting lower “tired” and “headache” ratings.[8]
POW!’s 200mg/200mg dosing at the 1:1 ratio is the most studied combination in the literature. Research comparing both agents alone and together found the combination produced significantly larger N2-P300 event-related potential amplitudes than either compound alone, suggesting the attention-supporting effects are additive rather than redundant.[9] Alongside Cognizin’s structural and cholinergic support, that’s the case for running all three at clinical doses in a single can.
-
Electrolytes – 540mg
Sodium (260mg), potassium (100mg), magnesium (80mg), and chloride (100mg) round out POW!’s formula with a combined 540mg electrolyte matrix. These aren’t filler minerals — they’re the foundation of cellular hydration and nerve signaling, and they’re lost with every hour of work, training, or gaming.
- Sodium is the primary driver of fluid retention. As the dominant cation in extracellular fluid, it governs osmotic pressure, which determines how much water stays in your plasma and tissues. Without sodium replacement after sweating, drinking plain water drops plasma sodium levels, suppresses vasopressin and aldosterone, and accelerates fluid excretion — the opposite of rehydration.[10] Research measuring sweat mineral composition across seven hours of exercise-heat stress found sodium consistently the dominant mineral lost, with potassium and calcium following in predictable patterns from the first hour onward.[11]
- Potassium works alongside sodium to maintain membrane potential across muscle and nerve cells. Its mechanism for supporting healthy blood pressure runs partly through the sodium-potassium ATPase pump, which promotes vasodilation and helps regulate sodium excretion — effects that become especially relevant in the context of high sodium intake.[12] The sodium-to-potassium ratio matters here: the combination at these doses is designed with balance in mind, not sodium in isolation.
- Magnesium at 80mg adds a different dimension. It’s a cofactor in over 300 enzymatic reactions, with a direct role in forming the Mg-ATP complex that powers nerve conduction and muscle contraction and relaxation. During sustained physical or cognitive effort, magnesium shifts from serum into active tissue to support energy metabolism where demand is highest.[13] Animal studies showed magnesium supplementation improved glucose availability in muscle and brain while delaying lactate accumulation — effects that map well onto sustained focus tasks and extended training sessions alike.
For a focus-oriented RTD built around Cognizin®, L-theanine, and caffeine, this electrolyte panel isn’t incidental. Intracellular ion balance is a prerequisite for the neurotransmitter activity those ingredients are meant to support — and for anyone using POW! during a long work session or workout, that 540mg matrix helps keep the substrate in place.

B-Vitamin Complex
POW!’s B panel covers Niacin/B3 (14.9mg/90% DV), Vitamin B6 (1.98mg/120% DV), Vitamin B12 (200mcg/8330% DV), and Biotin (50mcg/170% DV), each acting through distinct metabolic pathways relevant to the formula’s energy and focus goals.
- Niacin is the dietary precursor to NAD+ and NADP+, the redox coenzymes that power cellular energy production through the TCA cycle and electron transport chain. The 14.9mg dose sits near the established RDA, keeping B3 in cofactor-support territory rather than pharmacological range.[14]
- Vitamin B6’s active form, pyridoxal-5′-phosphate (PLP), cofactors over 150 enzymes spanning amino acid metabolism, neurotransmitter synthesis, and de novo production of NAD+ from tryptophan.[15] Its role in dopamine and serotonin biosynthesis adds a neurochemical layer that complements citicoline’s cholinergic support in this stack.
- Vitamin B12’s 8330% DV is a common overage in energy drinks, ensuring saturation of methionine synthase and methylmalonyl-CoA mutase, two pathways central to healthy neurological function and red blood cell maintenance.
- Biotin rounds out the complex with essential carboxylation reactions tied to fatty acid synthesis and glucose metabolism.
A double-blind trial in healthy adults found B-vitamin complex supplementation significantly reduced post-exercise blood ammonia accumulation and supported endurance performance, with B6 and B12 flagged as key contributors to those outcomes.[16]
-
Vitamin C – 110mg (100% DV)
Vitamin C (ascorbic acid) is a water-soluble antioxidant and enzyme cofactor involved in collagen synthesis, carnitine biosynthesis, and immune cell function. At 100mg, POW! covers the full daily value with a clean, practical inclusion.
Its most relevant mechanism here involves nitric oxide availability. Vitamin C protects tetrahydrobiopterin (BH4), the essential cofactor for endothelial nitric oxide synthase (eNOS). When BH4 oxidizes, eNOS uncouples and produces superoxide instead of nitric oxide, impairing vasodilation and circulation. Ascorbate prevents that uncoupling, helping maintain normal eNO production and vascular tone.[17] A meta-analysis of 44 RCTs found vitamin C supplementation produced a significant positive effect on endothelial function, with effect size positively correlated to dose.[18]
That vascular support pairs logically with POW!’s 540mg electrolyte matrix: the same endothelium that regulates hydration and nutrient delivery depends on the eNOS pathway to function normally.

Conclusion: A Clean Energy Drink That Actually Earns the Nootropic Label
Kyowa Hakko USA earns 4th patent for Cognizin Citicoline, further validating visual attention & cognitive performance benefits. New IP covers methods for enhancing attention, motor function & processing speed.
POW! Energy Drink is a sharp debut for Functional Fuel Co. The formula hits the full 250mg Cognizin® dose, pairs it with the well-matched and well-known caffeine and L-theanine stack, and backs everything with a complete electrolyte and B-vitamin panel. All of that in a zero-sugar, 5-calorie can.
The Cognizin® citicoline inclusion is the headline here though. Kyowa Hakko’s research at this dose level covers focus, attention, concentration, accuracy, and cognitive health support, and POW! uses it at that level rather than dropping to a sub-clinical amount for cost reasons. For consumers who’ve started reading the back of the can before buying, that distinction matters.
The comic book branding is bold and well-executed. Even non-comic book appreciators can still appreciate it. In a crowded category, owning a distinct visual lane is a smarter move than looking like every other clean energy competitor.
