You showed up. Now stay in it.

Gaily Sparkle is a clinician-formulated energy and focus blend for when you need to be present for the whole scene, not just the opening act. Smart stimulation, no crash, and a formula designed to clear your system before bedtime becomes a negotiation.

Sparkle is a three-ingredient formula built to get you sharp without the jitters, the crash, or the 1am regret. 

When your body processes caffeine, one of the compounds it converts it into is paraxanthine. Researchers identified it as a key contributor to caffeine's cognitive and performance effects, and it’s isolated here so it can do its job directly. Paraxanthine also has a shorter half-life than caffeine (so you won’t be lying awake at night questioning your life choices), metabolizes more predictably, and is better tolerated by people whose bodies process caffeine slowly.1 If caffeine has always felt like a gamble, this is the explanation and an alternative.

Sparkle pairs paraxanthine with L-theanine to moderate stimulation and support calm, focused attention, and lion's mane mushroom brings cognitive support that extends the formula's reach beyond alertness into actual mental clarity. The three work as a system: clean stimulation, focused output, and a smooth finish.

HOW TO USE

Start with 1 capsule* to assess tolerance. Pair with water. Pair with ambition.

Not recommended for use after 6pm, in conjunction with other caffeine products, or if you are sensitive to stimulants. Not for use for those under 18, breastfeeding, or pregnant.

Do not exceed 4 capsules (400 mg) in a 24-hour period.

*Most research on paraxanthine uses an effective dose of 200 mg. We formulated Gaily Sparkle at 100 mg per capsule deliberately. Some people want the full dose. Some people find 100 mg is exactly right for their system. One capsule gets you there either way, and if you want more, you take two. You know your body. We trust that.

BENEFITS

  • Smooth, sustained energy

    Paraxanthine delivers the alertness of caffeine without the rough edges. It metabolizes differently than caffeine, which may translate to fewer jitters, a gentler arc, and a shorter half-life so it clears your system before your head hits the pillow.1

  • Sharper focus, without the edge

    L-theanine works alongside paraxanthine to moderate stimulation and support smoother, directed attention. The pairing is deliberate: the goal is flow state, not fight-or-flight.2

  • Cognitive support that goes the distance

    Lion's mane mushroom rounds out the formula with a long history of use for brain health and cognitive function.3

KEY INGREDIENTS

  • Paraxanthine

    A metabolite of caffeine and a next-generation stimulant that supports alertness, reaction time, and focus with a cleaner metabolic profile than caffeine. Better tolerated by people who process caffeine slowly, and with a shorter half-life so it clears your system faster.1

  • L-Theanine

    An amino acid found naturally in green tea. Moderates the stimulating effects of paraxanthine and promotes sustained focus without sedation.2

  • Lion's Mane Mushroom

    A functional mushroom long valued in traditional Chinese medicine and studied for its support of cognitive function and memory. Contributes to the focus dimension of this formula.3

Gaily Sparkle FAQ

  • Sparkle is a clinician-formulated energy and focus blend built around paraxanthine, a caffeine metabolite with a cleaner metabolic profile and a shorter half-life than caffeine itself. Paired with L-theanine to smooth out stimulation and lion's mane for cognitive support, it's built for sustained clarity, not a jittery spike.

  • Paraxanthine is the compound your body converts caffeine into, isolated so it can act directly. It metabolizes faster and more predictably than caffeine, which means less of the jitters-and-crash cycle and less risk of it keeping you up at night.

  • Start with 1 capsule, 30 to 60 minutes before you need to be on. Not recommended after 6pm, or alongside other caffeine sources if you're sensitive to stimulants. Do not exceed 4 capsules (400 mg) in 24 hours.

  • Paraxanthine has a shorter half-life than caffeine, so it clears your system faster. That said, "not recommended after 6pm" is on the label for a reason. Everyone's metabolism is differerent, but best to respect that if you're sensitive to stimulants.

  • Unfortunately, add this to the long list of things you should avoid if pregnant or breastfeeding. And as always, feel free to consult with your doctor.
