Clear focus, without the comedown.
Most focus supplements buy you an hour, then hand you the crash. The Focus Stack is built differently — steady clarity that holds through the afternoon, no jitters.

Why most focus aids let you down
The problem isn't focus. It's the crash that follows.
Another coffee, a harder push, a quick spike — then the wired-but-foggy slump that costs you the evening. Stimulate hard, fade fast.
The Focus Stack pairs Brain & Focus and Mushroom Focus — botanicals, a full B-complex, and a 10-in-1 organic mushroom & adaptogen complex — formulated to support a calm, productive headspace. Clarity that holds, not a spike and a fall.
What you'll feel
Clarity that shows up, and stays.
Calm, productive mental energy from botanicals and a full B-complex — not a caffeine spike you’ll pay for later.
Steady concentration through the hours that usually slip, so your sharpest work doesn’t fade at 3.
Support for concentration and mental clarity through studying, deep work, and high-focus days.
A 10-in-1 organic mushroom and adaptogen complex to help you stay steady when the day asks a lot.
How it works
A simple daily protocol.
Two formulas, one easy routine — morning clarity and steady support when the day runs long.
Two capsules with your first meal. Botanicals, a full B-complex, and antioxidant vitamins for daily clarity.
A scoop of the adaptogenic blend in coffee, tea, or a smoothie for clarity and resilience that lasts.
Taken daily, it’s steady focus you can plan your hardest work around. Adjust or cancel anytime.
What's in the stack
Two formulas, one clear head.
Daily clarity from one, adaptogenic support from the other. Each does a job the other can't.
Honesty by subtraction
We score the evidence. Then we show our work.
Like every recommendation in the Agen app, each formula is graded by the strength of the science behind it — scored out of 10 and labelled by evidence tier. Here's exactly where the Focus Stack stands today.
Scores reflect the strength of current published research, not a guarantee of results — when the science strengthens, the score moves.

Their words, not our adjectives.
My focus holds through the afternoon instead of fading at 3. No wired feeling, no comedown — just steady.
I switched from a pre-workout-style nootropic that left me jittery. This is the first thing that gives me clarity without the edge.
The evidence score is what sold me. Nobody else tells you what they don’t know yet. I trust them more for it.

Questions, answered
No fine print.
How long before I notice a difference?
Many members feel calmer, steadier focus within the first week. The botanicals in Brain & Focus build with consistent use, so we suggest taking the stack daily for 30–60 days for the steadiest effect.
Is it safe?
Both formulas are third-party tested, organic, and vegan, and use structure/function botanicals. Note that Brain & Focus contains caffeine (from green tea), soy, and fish. If you're sensitive to stimulants, pregnant or nursing, or taking medication, check with your doctor first.
What if it doesn’t work for me?
There's no lock-in. You can pause, adjust, or cancel anytime from your account — no questions, no hoops. We'd rather you stay because it works.
Can I cancel my subscription?
Yes, anytime before your next ship date, in two taps from your account. Subscribe & save is a convenience that saves you 15%, not a contract.
Shipping and returns?
Free U.S. shipping on orders over $50 — the Focus Stack qualifies. Subscriptions ship every 30 days, and you're always notified before a renewal.
