GHOST Energy Drink

GHOST Energy is one of the flashiest cans on the shelf... but also one of the most thoughtfully built. While most energy drinks lean on caffeine and B vitamins and call it a day, GHOST layers in a legitimate nootropic stack: Alpha-GPC for focus, NeuroFactor for cognitive support, and a full gram of Carnipure L-Carnitine L-Tartrate for metabolic function. It's the kind of formula you'd expect from a brand that built its reputation in the supplement aisle before it ever put liquid in a can.

GHOST was founded by Dan Lourenço and Ryan Hughes in 2016 and built its name on transparent labels, authentic brand collaborations (Warheads, Sour Patch Kids, Welch's Grape Juice, Teenage Mutant Ninja Turtles, etc), and a community-first approach that was genuinely different from the corporate energy drink playbook.

In 2024, Keurig Dr Pepper acquired a 60% stake in the brand for roughly $990 million, valuing GHOST at approximately $1.65 billion, with the remaining 40% set to transfer in 2028. Dan and Ryan are staying on, and you can learn more in Episode #001 of the Bevlab Podcast with Dan. KDP's play is distribution, not formula interference, and the lineup has continued rolling out new flavors under the new structure, including collabs with KDP-owned brands like GHOST Energy 7UP Lemon Lime.

Zero sugar, 5 calories, no artificial colors. The formula has stayed consistent across the lineup. Here's what's in it.

GHOST Energy Drink Ingredients

Each 16 fl oz can provides the following key actives:

• Natural Caffeine (from Coffee Bean) — 200mg

  

  Natural caffeine from coffee bean blocks adenosine receptors in the brain and peripheral tissues. As adenosine accumulates during prolonged wakefulness or exercise, it drives fatigue and drowsiness. Caffeine's blockade of those receptors indirectly elevates dopamine, norepinephrine, and acetylcholine activity, sharpening arousal, reaction time, and pain tolerance.^[1]

  The 200mg dose falls within the well-studied ergogenic range. The ISSN position stand identifies 3-6 mg/kg as the consistent performance window, placing 200mg in the 2.5-3 mg/kg range for most adults -- sufficient to produce meaningful cognitive and physical benefits without pushing into diminishing returns.^[2] Improvements in sustained vigilance, attention, and reaction time are well-documented across rested and sleep-deprived populations, with effects emerging at doses as low as 32mg.^[1]

  The coffee-bean source also matters. Anhydrous caffeine tends to produce more reliable ergogenic effects than equivalent caffeine from brewed coffee, possibly because chlorogenic acid derivatives in roasted coffee interfere with adenosine blocking.^[3] Natural sourcing from green coffee bean extract avoids that variable, keeping the dose cleaner and more predictable than a cup of coffee would be.

• Alpha-GPC (Alpha-Glyceryl Phosphoryl Choline 50%) — 150mg

  

  Alpha-GPC is a choline-containing phospholipid that raises free choline levels in the brain, feeding the acetylcholine synthesis pathway involved in memory, focus, and muscle signaling.^[4] After ingestion, it's hydrolyzed in the gut and the released choline crosses the blood-brain barrier, where neurons convert it to acetylcholine.^[5]

  The cognitive evidence in healthy people is limited but increasingly credible. A 2024 randomized, double-blind crossover study in 20 resistance-trained men found both 630mg and 315mg doses significantly improved Stroop Total Score versus placebo, with the higher dose also producing faster test completion and quicker Flanker reaction times.^[6] Earlier trials at 200-400mg showed non-significant numerical improvements, suggesting dose and purity matter.^[7]

  GHOST's 150mg dose sits below the ranges that produced statistically significant cognitive results in human trials (315-630mg), but it does add to the daily dose of choline, which is especially important for those who aren't eating a lot of meat and eggs. Standalone cognitive effects at this dose are less certain, though the contribution alongside 200mg natural caffeine and NeuroFactor adds a relevant cholinergic dimension to the formula's focus angle.^[6] A two-week trial at 400mg also found nighttime motivation scores significantly higher versus placebo, with no anxiety effect.^[8]

• NeuroFactor™ (Coffea arabica Whole Fruit Extract) — 100mg

  NeuroFactor™ is a whole-fruit extract of Coffea arabica (the coffee cherry, not the bean), standardized to a minimum of 40% chlorogenic acids and containing less than 2% caffeine. Its primary claim is a well-documented ability to acutely elevate circulating BDNF (brain-derived neurotrophic factor), a protein central to neuronal development, synaptic plasticity, and learning.^[9]

  Two early within-subject studies in healthy adults found a single 100mg dose increased plasma BDNF by 137-143% compared to baseline, significantly outperforming brewed coffee, isolated chlorogenic acid, and green coffee caffeine extract. That result suggests the whole-fruit matrix drives the effect, not any single compound.^[9,10] A neuroimaging pilot in 8 older adults with subjective cognitive decline found 100mg produced faster reaction times, protected against accuracy decline under mental fatigue, and shifted brain chemistry toward greater excitatory signaling in attention and decision-making regions.^[1] A 28-day trial in 71 older adults with mild cognitive decline showed significant reaction time improvements versus placebo by day 7, persisting through day 28.^[11] GHOST's 100mg dose matches the studied dose exactly.

  No direct evidence from the supplied studies addresses a NeuroFactor-plus-caffeine synergy, though pairing a BDNF-modulating ingredient with the focused-energy stack here fits the formula's cognitive intent.

• Carnipure® L-Carnitine L-Tartrate — 1000mg

  

  Carnipure® L-Carnitine L-Tartrate is a high-purity form of L-carnitine. Its primary role is shuttling long-chain fatty acids across the inner mitochondrial membrane for fat oxidation, the process that generates ATP.^[2] At high exercise intensities, carnitine also buffers excess acetyl-CoA by forming acetylcarnitine, helping sustain energy metabolism and reduce lactate accumulation.^[3]

  GHOST provides 1,000mg per can. A dose-response meta-analysis of 37 RCTs identified 2,000mg/day as the point of maximum body weight reduction,^[4] and most exercise studies showing high-intensity performance benefits used chronic supplementation of 2-2.72g/day.^[3] The 1,000mg here falls below those ranges. That said, most energy drinks skip carnitine entirely, so even this dose represents a real differentiator.

  Recovery research using 1-2g/day demonstrated reduced creatine kinase release, lower lipid peroxidation markers, and attenuated muscle soreness versus placebo.^[2] The Carnipure designation signals quality, but what you do with it depends on cumulative daily intake from all sources.

• Taurine — 1000mg

  Taurine is one of the most abundant free amino acids in skeletal muscle, heart, and brain, where it regulates cell volume, stabilizes muscle membranes, modulates calcium handling in muscle tissue, and contributes to mitochondrial function.^[12,13]

  For an energy drink context, the exercise-relevant picture is reasonably solid. A 2025 meta-analysis of 23 single-dose trials found a small-to-moderate overall performance benefit, with aerobic endurance showing the most consistent signal.^[14] Taurine appears to support endurance partly by increasing fat oxidation: one study found a 16% increase in whole-body fat oxidation during cycling.^[15] The caffeine pairing matters here: a Bayesian network meta-analysis found caffeine plus taurine together significantly improved anaerobic capacity and reaction time beyond either alone.^[16]

  The 1,000mg per can sits is inside of the clinically studied range, although at the lower end of it. Most exercise research used 1-6g acutely, with the available meta-analysis finding no clear linear dose-response within that window, suggesting a threshold rather than a more-is-better effect.^[14] At this dose, meaningful ergogenic benefits are plausible, and the pairing with GHOST's caffeine stack is logical.

• AstraGin® — 25mg

  

  AstraGin® is a patented extract from NuLiv Science combining Astragalus membranaceus and Panax notoginseng saponins, standardized to ≥1.5% total saponins. Its proposed mechanism is upregulation of intestinal amino acid and nutrient transporters alongside modulation of tight junction proteins to improve gut barrier integrity.^[17] The mTOR pathway appears central to these effects, which is why single doses show modest results while multi-week supplementation produces stronger outcomes.^[17]

  The 25mg dose here is below every studied human dose. Clinical trials have consistently used 50mg twice daily (100mg/day), where researchers found statistically significant improvements in valine absorption (+14%), leucine absorption (+8%), and total EAA uptake (+12.74% in older adults) after four weeks paired with whey protein and resistance training.^[17] A separate crossover in healthy adults using 50mg found arginine absorption increased 17.3% (p=0.041).^[18] Whether 25mg produces meaningful absorption enhancement is unknown since no dose-response data exists in humans. As a supporting ingredient alongside GHOST's caffeine, Alpha-GPC, and carnitine stack, it's a credible inclusion at a sub-clinical dose.

• Vitamins

  • Vitamin C (as Ascorbic Acid) — 90mg (100% DV)

    Vitamin C hits the label at 90mg, matching the adult RDA. At this dose, plasma levels approach saturation in healthy individuals, the threshold where cellular and immune functions are meaningfully supported.^[19] Beyond generic antioxidant coverage, intracellular ascorbic acid also supports nitric oxide synthesis in endothelial cells by improving tetrahydrobiopterin availability for eNOS.^[20] For exercise context, low vitamin C status correlates with reduced aerobic capacity and elevated oxidative stress markers, with supplementation showing the largest benefit in those who were deficient at baseline.^[21] The 90mg dose is maintenance territory, not the gram-level dosing used in clinical exercise recovery research.

  • Niacin (as Niacinamide) — 16mg (100% DV)

    Niacin as niacinamide sits at 16mg, matching the adult RDA exactly. Niacinamide is one of two primary forms of vitamin B3. Unlike nicotinic acid, it doesn't cause the flushing response associated with pharmacological doses,^[22] although it's less effective than the "true" form of niacin (nicotinic acid). Both forms serve as precursors to NAD+ and NADP+, coenzymes essential to cellular energy metabolism across hundreds of reactions.^[23]

    At 16mg, this is nutritional sufficiency territory, well below the 500-3,000mg/day doses used in lipid-modifying research.^[24] The role here is baseline B3 repletion alongside the other B vitamins in the formula.

    

  • Vitamin B6 (as Pyridoxal-5-Phosphate) — 1.7mg (100% DV)

    Vitamin B6 as pyridoxal-5'-phosphate (PLP) is the directly bioactive coenzyme form, requiring no conversion in the liver unlike the pyridoxine hydrochloride found in most energy drinks. PLP participates in over 140 enzymatic reactions, including neurotransmitter synthesis (dopamine, serotonin, GABA), amino acid metabolism, and homocysteine conversion.^[1] Low B6 status is independently associated with elevated homocysteine, accelerated cognitive decline, and reduced muscle function in aging populations.^[5][25]

    The 1.7mg dose matches the adult RDA exactly, well below the 20-300mg/day ranges used in homocysteine and cognitive intervention studies.^[2] Choosing PLP over pyridoxine HCl is a meaningful formulation decision: high-dose pyridoxine can paradoxically inhibit PLP-dependent enzymes through competitive displacement, an issue that doesn't arise with PLP directly.^[6] This pairs logically with the B12 in GHOST's vitamin stack for baseline metabolic support.

  • Vitamin B12 (as Methylcobalamin) — 2.4mcg (100% DV)

    Vitamin B12 as methylcobalamin is a directly bioactive coenzyme form that supports one-carbon metabolism, neurotransmitter synthesis, and red blood cell production.^[26] Choosing methylcobalamin over synthetic cyanocobalamin is a modest but real formulation upgrade: animal data show roughly 13% higher liver retention and lower urinary excretion with the methyl form, and dosing frequency is the stronger predictor of B12 status overall.^[27,28]

    The 2.4mcg here matches the adult RDA, sitting far below the 647-1,032mcg/day range required to meaningfully reduce methylmalonic acid in adults with mild deficiency.^[29] Once again, this is repletion territory -- maintenance for those already sufficient, not a therapeutic dose. It rounds out the B-vitamin stack alongside B6 and niacin, supporting the baseline metabolic context GHOST's nootropic lineup depends on.

• Other Ingredients

  

  • Carbonated Water - The base. CO₂ dissolved under pressure gives GHOST Energy its carbonation and contributes to the clean, crisp mouthfeel.
  • Citric Acid - A naturally occurring organic acid used as an acidulant and flavor enhancer. It sharpens tartness in fruit-forward flavors and helps stabilize the formula.
  • Sucralose - A zero-calorie sweetener roughly 600 times sweeter than sugar. GHOST uses it alongside acesulfame potassium to achieve a clean sweet finish without the caloric load.
  • Tartaric Acid - Another organic acid, sourced primarily from grapes. Adds a slightly sharper, more complex tartness than citric acid alone and contributes to overall flavor balance.
  • Sodium Benzoate - A standard preservative that inhibits yeast and mold growth in acidic beverages. Used at low levels well within FDA-approved limits.
  • Potassium Sorbate - A second preservative working alongside sodium benzoate to extend shelf stability. Common in the category at these concentrations.
  • Acesulfame Potassium - A calorie-free sweetener blended with sucralose to round out the sweetness profile and reduce the aftertaste that either sweetener can produce on its own.
  • Natural & Artificial Flavors - The proprietary flavor systems that define each SKU's taste profile. "Natural" and "artificial" refer to the source of the flavoring molecules, not their chemical structure -- both are safe and tightly regulated.

Who It's For

• Supplement-minded energy drinkers: If you've ever wished your energy drink had the same ingredient transparency as your pre-workout, GHOST Energy is the closest thing to it on a convenience store shelf. The Alpha-GPC and NeuroFactor inclusions aren't decoration -- they're dosed at levels you'd actually put into a more complete stack.
• People who want clean energy without a high stimulant load: 200mg of natural caffeine is functional without being aggressive. The formula relies on Alpha-GPC's focus effect to smooth the experience rather than blunting caffeine directly, bringing a different approach than L-theanine, but one that works for most people.
• Flavor chasers: As with GHOST's powdered supplements, it's hard to beat what this team puts together on the flavor side, despite having more active ingredients than most of the competition.

The Formula Backs It Up

GHOST Energy earns its premium positioning. The caffeine dose is smart, the nootropic additions are meaningfully dosed rather than cosmetic, and the Carnipure carnitine inclusion sets it apart from the vast majority of cans in this category. This is a formula built by people who came from supplements, and it shows. Follow @BevlabMedia on TikTok and Instagram for coverage of the full GHOST lineup as new flavors drop.
