    The 2pm problem

    Tired of feeling drained halfway through your day?

    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.*

    30 vegan capsules. One capsule is one serving, so the bottle is a real month.

    PEAK ATP® · 400 mg per capsule

    Built for output.*

    A patented oral form of adenosine 5′-triphosphate. At 400 mg a day it 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.*

    Read the studies

    Enfinity® paraxanthine · 200 mg per capsule

    Built for focus.*

    Paraxanthine is what caffeine becomes — around 70% of the coffee you drink converts into it. Taken directly at 100–200 mg it has been studied against placebo for sustained attention, short-term memory and reaction time.*

    The research behind the two actives

    We picked the amounts first and built the capsule around them.

     

    Oral ATP, studied at 400 mg a day

    Wilson et al., 2013 — 12 weeks of resistance training in 21 trained men: greater gains in strength, jump power and muscle thickness than placebo.*

    Jäger et al., 2014 — post-exercise blood flow and artery dilation both up, measurable from week one.*

    González-Marcos et al., 2024 — meta-analysis of five randomised trials: 400 mg a day improved maximal strength versus placebo.*

    See every study

    Paraxanthine, studied at 100–200 mg

    Yoo et al., 2021 — placebo-controlled crossover at 200 mg: fewer card-sorting errors at hour six, faster reaction times from hour two, and vigilance that held steady where placebo declined.*

    Xing et al., 2021 — dose-response across 50, 100 and 200 mg: effects most consistent at 100 mg and 200 mg, with no clinically significant change in blood chemistry across a week of daily use.*

    Published remarks from the researchers who developed and studied these two actives.

    • On focus under pressure

      “Paraxanthine alone significantly improved cognitive performance. In contrast, caffeine alone increased the amount of errors to a shocking extent.”

      Dr. Ralf Jäger, PhD, FISSN · researcher and co-developer of Enfinity® paraxanthine

    • On oral ATP at 400 mg

      “Orally administered ATP as a disodium salt indeed increases blood flow in exercising animals and humans, most prominently during the recovery period from exercise. Significant improvements could be measured at a daily dose of 400 mg ATP in as little as one week.”

      Dr. Ralf Jäger, PhD, FISSN · lead author, Journal of the International Society of Sports Nutrition, 2014

      What you can check on the label

      One capsule is one serving, so a 30-count bottle is a real month. Two-capsule blends make the same 30-count last fifteen days.

        Questions people actually ask

        schedule

        How do I take it?

        One vegan capsule with water, ideally in the morning. Not within 4 hours of bedtime.

        local_cafe

        Can I still have my coffee?

        Not on top of the capsule. Spark already works on a stimulant pathway, and stacking it can overstimulate. If you want your coffee that morning, skip the capsule that day.

        no_drinks

        Is there caffeine in it?

        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.

        biotech

        Are the ingredients clinically studied?

        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. Every study is named on the product page.
