The 2pm problem
The second coffee. The energy drink. The sugar hit that lifts you for forty minutes and drops you lower than where you started.
Spark is one capsule in the morning. Two named actives, no coffee, no sugar, no twelve-ingredient blend.*

I’ll write a million reviews for Axiom Labs products!!! I Love them. I used to be in meetings hardly able to capture a word being said. I read a book and learned that my executive brain is always on hi speed. Once I started taking these, it was a game changer for me…I did not know why I felt like I was so stupid or lost…and I learned it was none of that negative talk…it was my brain needing to slow down. I have been taking these for years and won’t stop!
Since starting the supplement, I’ve noticed a significant improvement in my ability to concentrate, especially during long work hours. It also helps to reduce feelings of mental fatigue in the afternoon, keeping me productive. I appreciate that it’s formulated with quality ingredients. Overall, Spark has become an essential part of my daily routine, and I feel more mentally agile and alert. I highly recommend it to anyone looking to enhance their cognitive performance and support their brain health!
PEAK ATP® · 400 mg per capsule
A patented oral form of adenosine 5′-triphosphate — the molecule your cells actually spend to do work.
At 400 mg a day, oral ATP has been studied in resistance-trained adults for maximal strength, for how well power holds up late in a set, and for blood flow after exercise.*
Enfinity® paraxanthine · 200 mg per capsule
Paraxanthine is what caffeine becomes. Around 70% of the coffee you drink is converted into it — so here it is taken directly, skipping a conversion step your genetics control.
At 100–200 mg it has been studied against placebo for sustained attention, short-term memory and reaction time.* It is a stimulant, so treat it like one.
Coffee has to convert first. That conversion is genetic — which is why the extra cup works for some people and does nothing for others.
“One of the drawbacks of caffeine is that slow responders don’t get the optimal benefits… you have almost half of the people that get very little to no benefit of caffeine supplementation. And that has to do with genetics and how fast people are metabolizing it.”
Wilson et al., 2013Nutrition & Metabolism 10:57
Randomised, double-blind, placebo-controlled: 400 mg a day across 12 weeks of periodised resistance training in 21 trained men. Greater gains in total strength, vertical-jump power and muscle thickness than placebo, and less strength lost through a two-week overreaching block.*
Jäger et al., 2014JISSN 11:28
400 mg a day in 12 trained men. Ultrasound-measured blood flow and brachial artery dilation after exercise both increased significantly, and the effect was measurable from week one.*
Rathmacher et al., 2012JISSN 9:48
Placebo-controlled crossover, 400 mg a day for 15 days in 16 men and women. Low-peak torque held up better through repeated high-intensity sets.*
Freitas et al., 2019Journal of Strength and Conditioning Research 33(12):3345
A single 400 mg dose taken 30 minutes before training in 11 men produced more total squat volume than placebo.*
Purpura et al., 2017
400 mg a day for 15 days. Performance held up better through the later bouts of repeated maximal cycling.*
González-Marcos et al., 2024Sports 12(3):82
Systematic review and meta-analysis of five randomised controlled trials in 121 men: 400 mg a day improved maximal strength versus placebo, and 400 mg a day for up to 12 weeks was well tolerated in healthy adults.*
Every one of those trials used 400 mg a day. That is what is in one Spark capsule.
Yoo et al., 2021Nutrients 13:3980
Randomised, double-blind, placebo-controlled crossover: 200 mg of paraxanthine in 13 healthy adults, with cognitive testing every hour for six hours. Fewer card-sorting errors at hour six, faster Sternberg reaction times from hour two, and vigilance that held steady where placebo declined.*
Xing et al., 2021Nutrients 13:4478
Dose-response crossover of 50, 100 and 200 mg in 12 adults, acute and after seven days of daily use. Effects were most consistent at 100 mg and 200 mg, with no clinically significant differences in blood chemistry or in reported side effects across the week.*
Yoo et al., 2024JISSN 21:2352779
Crossover after a 10 km run comparing 200 mg of paraxanthine, 200 mg of caffeine, both together, and placebo on post-exercise cognition.*
Benowitz et al., 1995
A direct human comparison of the two molecules, in which caffeine raised diastolic blood pressure more than paraxanthine did.
Self-affirmed GRAS, 2021
Enfinity® paraxanthine holds self-affirmed generally recognised as safe status for use in food and beverage.
Those trials used 100–200 mg. One Spark capsule delivers 200 mg.
The caffeine problem
The second coffee. The energy drink. The forty-minute lift and the drop. Spark is one capsule built to replace that loop — not another stimulant on top of it.
Step 01
The extra cup buys forty minutes. Then you are lower than you started. That is the loop — not a lack of willpower.
Step 02
Most of a cup becomes paraxanthine in your liver. Slow metabolizers get little of the lift. That is genetics, not “you need a stronger brew.”*
Step 03
Enfinity® 200 mg is that molecule, taken directly. PEAK ATP® 400 mg is in the same capsule. No sugar — so nothing to spike, and nothing to drop.*
Step 04
The attention trials ran across a six-hour window — the stretch where the second coffee usually happens.* One capsule in the morning. That is the whole routine.
Same afternoon. Three ways to get through it. Only one of them is a named dose instead of another cup.

One vegan capsule with water, ideally in the morning. Not within 4 hours of bedtime. Do not exceed 2 capsules in a day unless a healthcare professional tells you otherwise.
Not on top of the capsule. Spark already works on a stimulant pathway, and stacking it can overstimulate. The researcher who co-developed paraxanthine says the same about the ingredient: use it on its own. If you want your coffee that morning, skip the capsule that day.
No caffeine. Paraxanthine is the molecule most of your caffeine converts into, taken directly — which means it is still a stimulant, so treat it like one.
It can, if you are sensitive to stimulants. Start with one capsule early in the day and add nothing else. If you get jitters, a racing heart, or trouble sleeping, stop taking it and speak to a healthcare professional.
PEAK ATP® 400 mg and Enfinity® paraxanthine 200 mg in a vegan capsule. One capsule is one serving.
Yes. Oral ATP has published human trials at 400 mg a day, and paraxanthine at 100–200 mg — the same amounts we put in the capsule. Both sets of studies are named on this page so you can read them yourself.
Most people take it in the morning and judge it on the same day. Give it a full week of consistent morning doses before you decide, and do not double the dose to chase a stronger effect.
Yes. Pause, skip, or cancel from your account, or email support. No phone call, no retention maze.
Contact support within 30 days of delivery and we will refund the product price.
