DA
Dopamine
Drives attention, motivation, reward processing, and executive function. Low dopamine activity shows up as poor concentration and difficulty starting or sustaining tasks — a hallmark of ADHD.

THE SCIENCE
Not hype. Function that feels good.
Most energy products rely on sugar and caffeine spikes — and an inevitable crash. Nootropic drinks avoid caffeine and fall short on real-world impact. Klar was built to work with your brain and your body, without the compromises.
THE CURVE
Steady energy. No cliff.
Klar — caffeine + L-theanine + nootropics
Typical energy drink — sugar + caffeine spike
Our formula was not designed in a marketing room.
It started with deep research into the neuroscience of energy, focus, and hydration. We examined the roles of key neurotransmitters — dopamine, norepinephrine, and acetylcholine — and built Klar to actively support those systems.
We do not throw trendy ingredients at the label. We select for synergy, efficacy, and everyday usability. No gimmicks — just a smarter, cleaner path to energy.
NE
Norepinephrine
Adrenaline's structural sibling. Focuses attention, increases arousal and alertness, and enhances memory formation. Imbalance is linked to brain fog and trouble focusing.
Alertness · Arousal · Memory
ACh
Acetylcholine
The first neurotransmitter ever discovered. Impacts attention and orchestrates synaptic plasticity — the brain's ability to adapt and form new connections.
Learning · Memory · Plasticity
INGREDIENT SELECTION
Chosen for a reason.
Caffeine blocks adenosine — the neurotransmitter behind feelings of tiredness — from binding to its receptors. It also enhances dopamine signaling by blocking its reabsorption, which is central to our synergistic approach: it works directly with the more dopaminergic nootropics in the formula. (Volkow et al., 2015)
An amino acid proven to mitigate caffeine's adverse effects like jitteriness and anxiety, while enhancing cognitive function by modulating serotonin, dopamine, and GABA. Recent studies also show favorable cardiovascular and organ-protective effects. (Sohail Ortiz et al., 2021; Li et al., 2022)
Our secret weapon. A building block of dopamine and norepinephrine, enhancing cognitive performance in stressful or demanding situations when those neurotransmitters run low. (Jongkees et al., 2015)
An amino sulfonic acid that regulates minerals and supports nervous-system function. Proven synergy with caffeine: co-administration augments both cognitive and athletic performance beyond either alone. (Ozan et al., 2022)
B1, B3, B6 (Pyridoxine HCl), and B12 (Methylcobalamin). B-vitamins act as coenzymes across cellular physiology, are critical to neurotransmitter synthesis, and help convert food into usable energy. (Hanna M et al., 2022)
A precursor to acetylcholine — the messenger behind learning and memory. Studies also show improved physical performance after just 6 days of supplementation. (Bellar D et al., 2015)
An adaptogen that boosts focus, fights fatigue, and supports cognitive function by regulating dopamine and norepinephrine, while helping the body manage stress. (Ivanova Stojcheva E et al., 2022)
Three complex electrolyte profiles — Himalayan pink salt, sea salt, and potassium chloride — built to be strong even as a standalone hydration product. Trace minerals like magnesium, calcium, and potassium support fluid balance and nerve function.
