What it does

Caffeine works by blocking adenosine receptors in the brain — adenosine is the compound that builds up throughout the day and makes you feel tired. Blocking it produces alertness, sharper focus, and improved reaction time. It also increases dopamine signaling, which is why caffeine improves mood and motivation alongside focus.

Why 50mg

Most energy products overdose caffeine — 150, 200, even 300mg in a single serving. That's not precision, it's brute force. At 50mg, you get the full cognitive benefit without the anxiety, jitteriness, or crash that comes from higher doses. Paired with L-theanine at a 1:3 ratio, this dose produces a measurably cleaner cognitive state than caffeine alone at any dose.

Works best with

L-theanine — the two together produce the "calm focus" effect that neither achieves alone at these doses.

What it does

L-theanine is an amino acid found naturally in green tea. It promotes alpha brainwave activity — the same state associated with relaxed alertness and creative flow. On its own it produces a calm, focused state. Combined with caffeine it dramatically smooths the stimulant effect, eliminating jitteriness and anxiety while preserving and enhancing focus.

Why 150mg

The 1:3 caffeine-to-theanine ratio is the most studied combination in cognitive performance research. At 150mg against 50mg caffeine, you get the full anxiolytic effect without sedation. The result is alert, calm focus — not the wired, scattered feeling most stimulants produce.

Caffeine — the synergy between these two is one of the most well-documented combinations in nootropic research.

What it does

Citicoline (CDP-choline) is a precursor to acetylcholine — the neurotransmitter most critical for memory, learning, and sustained attention. It also supports phosphatidylcholine synthesis, which maintains cell membrane integrity in neurons. The result is improved working memory, faster information processing, and sustained mental output that doesn't degrade across a long day.

Why 200mg

Most research on citicoline uses doses between 250-500mg/day. At 200mg per pouch, you get meaningful acetylcholine support, especially if using 2 pouches per day as directed. This is the ingredient that separates Pukka from every caffeine-only pouch on the market — nothing else in this format carries citicoline at a real dose.

200mg per pouch · highest-dosed ingredient in the stack

Works best with

N-acetyl L-tyrosine — together they support both the cholinergic and catecholaminergic systems for comprehensive cognitive support.

What it does

N-acetyl L-tyrosine (NALT) is a highly bioavailable form of L-tyrosine, a precursor to dopamine, norepinephrine, and adrenaline. These are the catecholamines responsible for drive, motivation, focus under pressure, and the ability to perform when you're stressed or sleep-deprived. NALT replenishes catecholamine levels that get depleted during cognitive or physical stress.

Why 150mg

The N-acetyl form has significantly better bioavailability than standard L-tyrosine. 150mg of NALT delivers the equivalent effect of a much higher dose of regular tyrosine. This dose is particularly effective for maintaining performance when you're pushing hard — whether that's a demanding workday, a training session, or an afternoon where your energy would normally crater.

150mg NALT per pouch · highly bioavailable form

Works best with

Rhodiola rosea — both ingredients are particularly effective for maintaining performance under stress, and their mechanisms are complementary.

What it does

Rhodiola rosea is an adaptogenic herb with extensive research behind it. It works primarily by modulating the HPA axis — the stress response system — reducing cortisol output and improving the body's resilience to physical and mental stress. In practical terms this means your output doesn't collapse when the day gets hard. It also has direct effects on serotonin and dopamine pathways, supporting mood and mental stamina.

Why 40mg

Rhodiola is one of the few adaptogens with a robust research base — studies typically use standardized extracts at 3-6% rosavins. At 40mg of a standardized extract, you're in the effective range for stress buffering and fatigue reduction without the sedative effects that can occur at very high doses. This is the dose that keeps you performing, not the dose that relaxes you.

Pukka dose

40mg standardized extract per pouch

Works best with

NALT — together they form the stress-performance axis of the Pukka stack, keeping output high when circumstances would normally drag it down.

What it does

B12 (as cyanocobalamin) is essential for the synthesis of myelin — the protective sheath around neurons — and for the production of red blood cells that carry oxygen to the brain. It's also a critical cofactor in the conversion of homocysteine to methionine, which supports neurotransmitter synthesis. Deficiency is more common than most people realize and leads to fatigue, brain fog, and mood disruption.

Why 25mcg

At 1040% of the daily value, this is a generous dose — but B12 is water-soluble so excess is excreted harmlessly. The higher dose ensures that even people with suboptimal absorption (common in people who eat limited animal products) get sufficient intake. B12 is the foundation that makes everything else in the stack work properly at the cellular level.
