No proprietary blends. No hidden fillers. Every compound in THNK Focus Powder is listed here with its mechanism and the science behind why it is in the formula.

Zero proprietary blends
Manufactured in the USA
Natural caffeine balanced with L-Theanine
Alpha-GPC
300mg
Memory + attention
The Focus Chemical Your Brain Actually Makes
Alpha-GPC is a choline compound that raises acetylcholine the neurotransmitter your brain uses for sharp attention, working memory, and staying locked in. At 300mg per serving, it's dosed at the level used in clinical research. No stimulants. Just your own chemistry, working the way it's supposed to.
MemoryAttentionFocus
The science
300mg of Alpha-GPC has been shown in research to increase acetylcholine synthesis, supporting improvements in memory recall, sustained attention, and processing speed especially under cognitive load.
Natural Caffeine
200mg
Clean energy + alertness
Caffeine That Works With You, Not Against You
200mg of caffeine sourced from green tea not synthetic, not spiked. It hits cleaner, lasts longer, and pairs with L-Theanine in this formula to keep the edge without the anxiety. You'll feel awake. Not wired.
EnergyAlertnessFocus
The science
Green tea derived caffeine delivers the same alertness boosting effects as synthetic caffeine, with research suggesting a smoother absorption profile. At 200mg paired with L-Theanine, it's the most studied nootropic combination for sustained focus without jitter or crash.
L-Theanine
100mg
Calm focus + anxiety reduction
Focus Without the Feeling of Too Much Coffee
L-Theanine is an amino acid found naturally in green tea that promotes relaxed alertness no sedation, no stimulation, just a quieter mind that can actually concentrate. At 100mg it counterbalances caffeine's edge, so you stay sharp without feeling strung out.
CalmFocusAnxiety Relief
The science
Multiple double blind studies show L-Theanine increases alpha brain wave activity the same mental state associated with relaxed concentration. Combined with caffeine, it consistently outperforms caffeine alone for sustained attention and reduced anxiety response.
Asian Ginseng
50mg
Mental stamina + stress resilience
The Adaptogen That Keeps Your Brain Online
Asian Ginseng has been used for centuries to fight mental fatigue and modern research backs it up. At 50mg of concentrated extract, it helps your brain maintain performance under pressure, reducing the cognitive dip that hits when you're stressed, sleep deprived, or deep into hour three of studying.
EnergyStaminaStress ReliefFocus
The science
Clinical studies show Asian Ginseng extract improves working memory and mental performance under fatigue, while also supporting healthy cortisol response helping you stay sharp when stress would otherwise slow you down.
L-Arginine
1000mg
Blood flow + nutrient delivery
More Blood Flow. Sharper Brain.
L-Arginine is a precursor to nitric oxide the compound your body uses to relax and widen blood vessels. At 1000mg, it supports increased cerebral blood flow, meaning more oxygen and nutrients reaching your brain when you need them most. Better circulation isn't just for the gym. It's for the study session too.
Blood FlowFocusEnergyCirculation
The science
L-Arginine converts to nitric oxide in the body, a vasodilator shown to improve cerebrovascular circulation. Enhanced blood flow to the brain is associated with faster processing speed, improved concentration, and reduced mental fatigue during prolonged cognitive tasks.
Full B-Vitamin Complex
B1 0.40mg · B2 0.43mg · B3 5.20mg · B6 0.56mg · Folate 133mcg · B12 0.80mcg · B5 1.66mg
Neurological function + energy metabolism
The Foundation Every Other Ingredient Runs On
B vitamins aren't flashy but they're essential. Your brain uses them to produce neurotransmitters, convert food into usable energy, and maintain the nerve pathways that make focus possible in the first place. Most people are running at least partially deficient. This formula covers all seven, so nothing else in the stack is working against a deficit.
EnergyMoodNeurological HealthFocus
The science
B vitamins particularly B6, B12, and folate are critical cofactors in the synthesis of dopamine, serotonin, and norepinephrine. Deficiencies are directly linked to cognitive decline, brain fog, and low mood. This full spectrum complex ensures your baseline neurochemistry is covered before anything else kicks in.
Black Pepper Extract
5mg
Absorption amplifier
Makes Everything Else Work Harder
Black Pepper Extract standardized to piperine isn't here for cognitive benefits on its own. It's here to make sure everything else actually gets absorbed. Piperine inhibits the enzymes that break down nutrients too quickly, increasing bioavailability of the other ingredients by up to 20x in some cases. Without it, you'd be getting a fraction of what's on the label.
AbsorptionBioavailabilitySynergy
The science
Piperine has been shown in multiple studies to significantly enhance the bioavailability of a wide range of nutrients and compounds including B vitamins, amino acids, and plant extracts by inhibiting intestinal and hepatic metabolism. It's the reason clinical doses actually reach your bloodstream.
Inositol
600mg
Mood regulation + dopamine signaling
The Ingredient That Quiets the Noise
Inositol is a naturally occurring compound that plays a direct role in how your brain responds to serotonin and dopamine. At 600mg, it helps regulate the signal sensitivity of those receptors meaning your brain's reward system works more like it's supposed to. Less mental noise. Less compulsive distraction. More ability to sit with a task and actually finish it.
MoodDopamineFocusAnxiety Relief
The science
Inositol acts as a second messenger in neurotransmitter signaling pathways particularly serotonin and dopamine. Clinical research has shown it reduces anxiety and compulsive thought patterns, with studies using doses of 600mg–18g depending on application. At 600mg, it contributes meaningful receptor level support for calm, directed focus.

Nothing hidden. Nothing wasted.

Every ingredient in THNK is there for a reason. Every dose is calibrated. Every mechanism is documented.
