Dawn to Dusk Science

WHAT IS DAWN TO DUSK?

Actually, we call it D2D for short. It's a physician-formulated energy supplement designed to help everyone power through their long days at work, training, and life. Everything in the world runs at full speed and we know that most people want to do it as well.

We created a product that ultimately allows for slow release energy throughout the day. Long gone are the days of 10+ cups of coffee just to stay awake when you have Dawn to Dusk.

Read below about what makes Dawn to Dusk a top selling energy supplement and the only one with this combination of ingredients.

INGREDIENTS

Dawn to Dusk contains five powerful ingredients that work together to deliver sustained, crash-free energy.

Pterostilbene Caffeine Co-Crystal

This is where Dawn to Dusk really stands apart. Pterostilbene Caffeine Co-Crystal is a patented technology that bonds caffeine molecules with pterostilbene—a powerful polyphenol found naturally in blueberries.

Why does this matter?

When caffeine is bonded to pterostilbene in a co-crystal structure, it fundamentally changes how your body absorbs and processes caffeine. Research shows this co-crystal form delivers approximately 30% slower absorption compared to regular caffeine, resulting in a more gradual, sustained release of energy.

Benefit	Result
Caffeine Delivery	~30% more delivered to bloodstream vs regular caffeine
Half-Life	~8 hours (vs ~3 hours for standard caffeine)
6-Hour Mark	~51% more caffeine still circulating
Pterostilbene Delivery	~50% more vs pterostilbene taken alone

But here's the bonus: pterostilbene itself is a superstar ingredient. It has approximately 4x better bioavailability than its cousin resveratrol and a 7x longer half-life. This means you're not just getting better energy—you're also getting powerful antioxidant support for:

Cognitive function
Cardiovascular health
Healthy aging

TeaCrine® (Theacrine)

TeaCrine is a nature-identical compound containing pure theacrine, sourced from the Camellia kucha tea plant. It works similarly to caffeine by blocking adenosine receptors (the "sleepy" signals in your brain), but here's where it gets interesting: theacrine also activates dopamine D1 and D2 receptors.

What does that mean for you?

Dopamine is your brain's "motivation and reward" neurotransmitter. By influencing dopamine pathways—specifically increasing activity in the nucleus accumbens—TeaCrine helps support:

Enhanced motivation and drive
Improved mood and sense of well-being
Better focus during demanding tasks
Sustained mental energy for task completion

The best part? An 8-week human clinical trial demonstrated that TeaCrine does not cause habituation. Unlike caffeine, where you need more and more over time to feel the same effects, TeaCrine maintained its effectiveness throughout the entire study period without tolerance buildup.

TeaCrine also has a longer-lasting effect profile (4-8 hours) compared to caffeine's peak effects (1-2 hours), and research shows it doesn't significantly impact heart rate or blood pressure.

Caffeine Anhydrous

We've included a precise dose of standard caffeine anhydrous to provide that initial spark of alertness you need to get going. But because it's combined with the co-crystal and TeaCrine, you won't experience the harsh spike and crash typical of caffeine-only products.

Think of it as the ignition switch that gets things started, while the other ingredients keep the engine running smoothly all day long.

Coleus Forskohlii

Coleus forskohlii contains forskolin, a compound that activates an enzyme called adenylate cyclase. This increases cellular levels of cyclic AMP (cAMP), a crucial signaling molecule involved in numerous metabolic processes.

Why include it?

Supports metabolic function and energy production at the cellular level
Research suggests it may help reduce fatigue and improve cognitive performance
Works synergistically with the other ingredients to optimize overall energy output

Huperzine A

Derived from the Chinese club moss (Huperzia serrata), Huperzine A is a potent acetylcholinesterase inhibitor. In plain English, it helps maintain higher levels of acetylcholine—a neurotransmitter critical for memory, focus, learning, and attention.

Key benefits:

Effectively crosses the blood-brain barrier for targeted cognitive support
Helps preserve acetylcholine levels for sustained mental clarity
Provides neuroprotective and antioxidant properties
Well-tolerated even at higher doses in research studies

When you're running on all cylinders mentally, you feel more capable, more productive, and more "in the zone." That's the Huperzine A advantage.

WHAT MAKES DAWN TO DUSK SPECIAL?

No other energy supplement puts together this combination of ingredients at our doses.

The Synergy Effect

Combination	What Happens
Caffeine + TeaCrine	Caffeine actually increases theacrine's bioavailability—you get more from both ingredients. A study on high-level soccer players found this combination provided greater cognitive benefits than either supplement alone.
Co-Crystal + Caffeine Anhydrous	The co-crystal provides extended-release energy while standard caffeine delivers immediate alertness. Together, they create a smooth energy curve without peaks or valleys.
Huperzine A + Coleus Forskohlii	While the stimulants handle energy and alertness, these ingredients support the cognitive and metabolic machinery that keeps everything running efficiently.

We found that this combination of dosing really allows for true extended, long lasting, no crash energy. These ingredients synergistically work together to heighten your focus, mood, and motivation.

WHAT YOU'LL ACTUALLY FEEL

Time	Experience
Hour 1	Clean, focused energy kicks in without the jitters. You feel alert and ready to tackle your day.
Hours 3-5	This is where most energy products fail. With Dawn to Dusk, you're still going strong. Focus remains sharp, motivation stays high, and there's no mid-afternoon crash looming.
Hour 6+	Sustained mental clarity and physical energy. You're finishing your day as strong as you started—not dragging yourself to the finish line.

Dawn to Dusk

POWER UP

Made with effective, high-quality ingredients, Dawn to Dusk was designed to be a better and healthier alternative to old fashioned energy supplements. With as little caffeine as a single cup of coffee, Dawn to Dusk provides up to 10 hours of clean energy and helps improve mood, heighten mental focus, and boost productivity.

Unlike coffee and energy drinks where you feel an instant burst of energy and a crash later on, Dawn to Dusk gives you a smoother and longer lasting supply of energy with no jitters, no afternoon crash, and of course, with no calories or sugar.
