Why we built this
The day swings. The work of the stack is to flatten it into a steady working line.
Forty messages before breakfast, screens running all day, the constant context-switching. The brain runs on specific neurochemistry to hold this load, and the day spends it faster than food alone refills.
The problem
The shape of the day is recognizable. Heavy mornings, a 2 p.m. drop, an evening with less left than the morning promised. That is the swing. Seven compounds at studied doses, taken together, flatten the swing into a steady working line. Not in a multivitamin. Built into one daily sachet.
Why a sachet, not a shelf
Not seven jars on the counter. Not a powder in a shaker. Not nine reminders in your Health app. Seven jars means seven expiry dates and seven chances to run one out and quietly break the stack. One sachet cannot break that way. One pinch with breakfast, thirty seconds, done. No proprietary blends, no fillers, no "fast-thinking" promise. Seven compounds, named, dosed to studied levels, sealed into one daily pull. That is the design.

The Stack · Seven Compounds
Seven compounds, one daily sachet.
Named, dosed to studied levels, cited to source. Tap any card for the full Supplement Facts panel and mechanism.
Methyl B-Complex
Energy · Methylation
Eight bioactive B-vitamins in the methylated forms that still work if your MTHFR gene runs slow. Daytime energy without the caffeine cliff.
L-Taurine
Calm · Nerve
800 mg of the amino acid that quiets an overactive nervous system without sedating it. The opposite of caffeine, in the same cup.
NAC
Antioxidant · Cellular
600 mg N-Acetyl Cysteine. The precursor to glutathione, the antioxidant the body uses to handle cellular stress. The quiet antioxidant backstop of the stack.
Rhodiola Rosea
Energy · Stress
250 mg standardized Arctic adaptogen. Holds cognitive performance steady under high load, no stimulant spike or crash.
L-Theanine
Calm · Focus
200 mg of the green-tea amino acid that takes the jitter off coffee and leaves the focus intact.
Omega-3 EPA / DHA
Cardio · Cognitive
1000 mg pharmaceutical fish oil. EPA and DHA are the structural fats your brain is built from. Pacific anchovy, no off-taste.
Inside the production
Real compounds, real verification, sachet by sachet.
Manufactured at a US partner facility under FDA dietary supplement regulations 21 CFR Part 111 and Part 117. Each sachet passes inline machine-vision before it leaves the line.

Dose philosophy
Studied doses. Not "label doses".
Most stacks pad the back of the label with botanicals at half the studied dose, because hitting the real dose costs three times as much per sachet. We didn't. Every compound in 30BASE Cognitive Stack sits at or above the level used in published clinical trials. Tyrosine 1000 mg, Taurine 800 mg, and Theanine 200 mg all sit at or above the trial dose (Mahoney 2007, Wu 2009, Nobre 2008). NAC 600 mg (Atkuri 2007) and Rhodiola 250 mg standardized at 3% rosavins (Panossian 2010). Omega-3 EPA 400 plus DHA 300 mg, above the 250 mg cognitive threshold (Calder 2020). The Methyl B-Complex in fully bioactive forms (Stover 2004).
Three filters
- 01 Studied dose. There has to be a published clinical-trial dose for the indication, and we have to fit inside it.
- 02 One daily sachet. It has to fit inside one daily pull you can actually swallow with breakfast. No second pill to track, no powder to mix.
- 03 Stack compounding. The mechanism has to compound with at least two of the others, so the stack does more than the sum of bottles.
One honest exception
Six of seven at or above the studied dose. Tyrosine 1000 mg sits at the daily-supplementation tier, below the 100 to 150 mg per kg loading dose used in acute-stress trials (Mahoney 2007). At 70 kg that loading dose would be 7 to 10 grams in one serving, which is not a thing you can put in a sachet. Daily 1000 mg is the dose used in the maintenance arm of those same studies and what we ship. We would rather tell you that than fake the number on the label.
What 30BASE is not
Not a wellness brand.
Not the category
Not "adaptogen-infused". Not a "feminine vitality" or "masculine performance" SKU. Not a glossy lifestyle. Not a powder you stir into oat milk. Not a moon-phase reset.
We are a clinical formulation. Manufactured in a US cGMP-certified facility operating under FDA dietary supplement regulations 21 CFR Part 111 and Part 117. Tested by ISO/IEC 17025 accredited third-party laboratories. Named and dosed in milligrams on the label.
Not on the label
- No caffeine.
- No yohimbine, no synthetic stimulants.
- No proprietary blends.
- No undisclosed actives.
- No artificial colors.
- No GMO ingredients.
- No fast-thinking promise. No overnight transformation.
- No marketing fluff on the label.
Every milligram printed on the label. Every compound named, dosed, cited to the trial that sets the dose range.
What to expect, by timeline
How the stack actually settles in, week by week.
30BASE Cognitive Stack is not a stimulant and not a fast-kick nootropic. Most of the seven compounds build up in tissue or quietly support pathways the body already runs. The honest curve below is what most people notice, and when. Individual response varies.
First week · quiet, with something working underneath
The volume comes down.
On the first day you may notice a small effect from L-Theanine (200 mg) and L-Taurine (800 mg). Theanine has been studied for its effect on alpha brain rhythm, the state of relaxed-but-awake attention (Nobre 2008). The head goes quieter without sleepiness; thoughts stop running over each other. L-Tyrosine (1000 mg) is a precursor the body uses on demanding days to keep up with what stress and load are using up (Jongkees 2015). On easy days you barely notice it. On heavy days you notice that the day is easier to carry than it usually is.
Second to fourth week · under the surface, things settle
The background gets quieter.
Around two weeks in, the change is hard to describe with a single word. Rhodiola Rosea (250 mg) is a standardized adaptogen that supports a normal stress response (Olsson 2009). Same deadline, same conversation, same traffic. The reaction is quieter, the recovery is faster. NAC (600 mg) provides cysteine, the rate-limiting amino acid the body uses to make glutathione, its main intracellular antioxidant. Methyl-B complex comes online in bioactive forms that work for the roughly one third of the population whose methylation pathway runs slow (Liew & Gupta 2015).
Second to third month · what builds up underneath
The slow compounds catch up.
Omega-3 (1000 mg fish oil, EPA 400 + DHA 300) is the slowest. EPA and DHA are structural components of every cell membrane and take 8 to 12 weeks to build up in tissue. This is the case where the body does its work in the background, on a timeline long enough that you do not feel the difference day to day. If your physician already tracks bloodwork, Omega-3 index and homocysteine are two markers worth following on this kind of stack. Effect is quiet by design.
What you will not get
No quick kick. No overnight rewrite.
30BASE Cognitive Stack is not a treatment and does not claim to be. The way long-term users describe the stack is by its absence. When you forget it for a week on a trip, you notice that the steady state you had gotten used to was the daily work of these seven compounds underneath. That is the paradox of a foundation: when it works, it disappears.
30 days to a steady working state. Quiet by design. *These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
What backs the label
Four things you can verify, in plain English.
There is no "FDA-approved supplement", and any brand that says so is bluffing.
Four anchors behind the label, regulation-grounded and process-anchored.
01
cGMP · 21 CFR Part 111 and 117
Good Manufacturing Practice.
Manufactured in a US cGMP-certified facility operating under FDA dietary supplement regulations 21 CFR Part 111 and Part 117. The federal quality framework that governs identity, strength, and purity of every product released.
02
FDA-Compliant Facility
Subject to periodic FDA inspection.
Our US manufacturing partner operates under FDA dietary supplement rules and is subject to periodic FDA inspections. FDA does not approve dietary supplement products themselves. What FDA regulates is the facilities that make them.
03
CoA on Request
Tested by ISO/IEC 17025 third-party laboratories.
Potency and purity tested by ISO/IEC 17025 accredited third-party laboratories on a skip-lot sampling basis. Identity, heavy metals, and microbials screened to standard. Certificate of Analysis available on request for every compound.
04
Per-Sachet Vision Verification
Every sachet checked, not just every batch.
An inline machine-vision system content-verifies each individual sachet as it is filled and sealed. Any anomaly the vision system flags is reviewed by human QC before the sachet leaves the line. Per-unit verification, above the per-lot sampling that is standard for the category.

How it ships
Subscribe once. Land on time. Take in the morning.
No stack to learn, no shelf to refill, no decisions at 7 a.m.
Step 01
Subscribe
A flat $179 a month, $5.97 a day. Cancel or pause from your account in two clicks. No phone call. No retention script.
Step 02
Receive
Each box holds 30 sachets and ships from our US partner facility, free across the contiguous 48, 3 to 7 business days in transit. It lands two to three days before the current box runs out, so the stack never breaks and the steady state holds.
Step 03
Take
The day starts with thirty seconds. Tear the sachet across the perforated strip, tip eight capsules into your palm, swallow with breakfast and coffee. The fat in your meal carries the fish-oil softgel cleanly. No second dose. No mid-day reminder. No pill organizer. Done. The format people actually keep up after 30 days, because it does not ask anything of you the rest of the day.
Not for everyone
Who this is for, and who it isn't.
We'd rather lose the order than ship a sachet you don't need.
The modern day
Built for the constant-switching day.
The focus group, Tyrosine, Theanine, Taurine and the Methyl B-Complex, is built around supporting steady attention at the doses published research used. One sachet instead of four jars. No stimulant in the formula.
Stress and recovery
Built for high-demand stretches.
The stress and recovery group, Rhodiola and NAC at studied doses, is built around supporting a normal stress response. Most people describe the change over two to three weeks as quieter, not louder. Individual response varies.
Who this isn't for
If any of these is true, this isn't your stack.
- You're under 18.
- You're pregnant or breastfeeding.
- You have a diagnosed deficiency that needs a clinical dose, not a daily multi.
- You want a stimulant. There's no caffeine or yohimbine in here.
- You want a shelf full of bottles to mix and match. We sell one product. One sachet. Once a day.
- You're shopping on price. We're not the cheapest, by design.
If you take any prescription medication daily, clear the stack with your physician before starting. Rhodiola can interact with thyroid medication and certain SSRIs.
How this compares
Same daily ritual, different trade-offs.
Versus the three options most people actually consider when they decide to fix their stack.
| 30BASE | Multi-pill stack | Greens powder | Single-compound bottles | |
|---|---|---|---|---|
| Daily ritual | 1 sachet, with breakfast | 5 to 8 pills, often split AM / PM | 1 scoop in water, often gritty | Mix-and-match, daily decision fatigue |
| Compound count | 7 named, focused on cognition + recovery | 8 to 15, sourced separately | 30+ greens, often trace doses | Whatever you've bought that month |
| Dose disclosure | Per-compound mg, on label, cited | Yes, on each separate label | Often "proprietary blend", undisclosed | Yes, varies by brand |
| Third-party CoA | Yes, on file, available on request | Varies by brand, rarely all of them | Rarely, often only "tested for purity" | Varies by brand |
| Designed for | Cognitive load of the modern day | General wellness | Nutrient density, not cognition | Single-target use cases |
| Monthly cost | $179 / mo flat | $265 to $349 | $80 to $110 | $265 to $349 |
Cost ranges reflect typical US retail for spec-equivalent, studied-dose alternatives at manufacturer MSRP. Greens powders are cheaper because they aren't doing the same job: 30+ trace-dosed botanicals at fractional studied doses, no cognition stack.
Reviews
Public reviews appear here once the first 50 customers have completed their 30-day window.
We launched recently. The first cohort is running their first month right now. Verified-subscriber reviews show up on this page once the 30-day arc closes for at least 50 of them, with the lot number against each review and a link to the full Certificate of Analysis for the box that customer received. Anything we put here today would be marketing prose. Showing you marketing prose is the kind of brand we wrote the rest of this page against. If you want to be one of the first 50, see pricing below.
If we're being direct
You're not buying a sachet. You're buying back the part of the day that the swing keeps taking.
Seven compounds at studied doses, taken with breakfast. The stack is not a stimulant and not a quick fix. It is the daily foundation for a brain that runs on focus and information all day. The effect is quiet, accumulating, and most honestly described by its absence: when you forget the stack for a week, you notice that the foundation you had gotten used to was the work of these seven compounds underneath.
Seven compounds at studied doses. One sachet a day.
CLEAR BASE LTD · London · the team behind 30BASE
Before you start
Common questions, short answers.
Behind the label
A daily cognitive foundation, built to one rule. Every milligram on the label, your name on the sachet, a Certificate of Analysis on request for every compound.
Will I feel wired or stimulated?
No. There is no caffeine, no yohimbine, no synthetic stimulants. The stack lifts the substrate (neurotransmitters, antioxidant capacity, methylation cycle) so your existing energy works better, not louder. People describe it as steady, not buzzed.
Can I take this with my morning coffee?
Yes. The L-Theanine and L-Taurine pairing is specifically what softens the caffeine kick. Most people find the stack pairs cleanly with one or two cups, fewer afternoon dips, no jitter, no 3 p.m. crash. Take with breakfast for clean absorption.
How does the subscription work?
A flat $179 every 30 days, $5.97 a day, free shipping across the contiguous 48. Your card is charged each cycle until you cancel or pause. Cancel or pause from your account in two clicks — no phone call, no retention script. No starter markup, no introductory pricing, no autorenewal trap. The price is the same every month from day one.
Can I cancel or pause?
Yes. Two clicks from your account at 30base.com/account: open Manage subscription, then choose Skip next box, Pause for 30, 60, or 90 days, or Cancel. No autorenewal trap, no win-back gauntlet, no fine print that rolls you over. Your card is not charged once a subscription is cancelled or paused, period.
When will I notice a difference?
Individual response varies. Some compounds (Theanine, Taurine) act within the first day. Others (Tyrosine, Rhodiola) work cumulatively over weeks. Omega-3 and the B-complex build up in tissues gradually over 8 to 12 weeks. Effect is cumulative and individual starting point matters.
Take with morning coffee, or empty stomach?
Take with breakfast, with or without coffee. The fat in your meal helps the Omega-3 softgel absorb cleanly, and the food layer is gentle on Rhodiola and NAC. L-Theanine and Taurine pair cleanly with caffeine and take the jitter off.
What if I miss a day?
Skip it and take the next sachet the following morning. None of the compounds are dose-dependent on a single day; the benefit accumulates over weeks. Don't double-dose to "catch up".
Why is my name printed on the sachet?
Because your box is personally produced for your order, not pulled from a shelf. Each sachet is printed with your name, the day count, and the lot number, the same traceability discipline that puts every milligram on the label. Accountability you can hold, not a personalization gimmick.
Are these doses safe long-term?
Yes. Every compound sits inside the dose range used in published clinical trials and below the tolerable upper intake level (UL) set by NIH. If your physician already tracks lab markers, Omega-3 index and homocysteine are two worth following on this kind of stack.
I noticed bright-yellow urine in the first days. Is that normal?
Yes. The Methyl B-Complex contains riboflavin (B2), and any amount the body does not use is excreted in urine, bright-yellow. This is the expected color of riboflavin and not a sign of anything wrong. It typically settles within a week or two as the body adjusts to the daily dose.
Any common allergens? Is it vegan?
The sachet contains fish derivatives (Pacific anchovy fish oil for the Omega-3 softgel), so the stack is not suitable for vegetarians or vegans. Everything else is gluten-free, soy-free, and dairy-free.
Safe with prescription medications?
Rhodiola can interact with thyroid medication and certain SSRIs. NAC can thin mucus and may affect blood pressure medication. If you take any prescription drug daily, clear the stack with your physician before starting.
Why a UK company shipping from the United States?
CLEAR BASE LTD is the UK-registered legal entity that owns the brand, hires the team, and signs the contracts. Manufacturing and US fulfillment run through a US partner facility because supplements ship faster, cleaner, and cheaper to US customers from inside the country. Two locations, one operation, one customer.
Who runs 30BASE?
30BASE is operated by CLEAR BASE LTD, a UK-registered company. The team is small and based internationally, focused on product, operations, and customer support. Manufacturing runs through a US-based cGMP-certified partner. Third-party testing runs through ISO/IEC 17025 accredited laboratories. The formulation is based on published clinical trials, cited per compound on this page.
Where is 30BASE Cognitive Stack manufactured?
In the United States. Production runs through a US cGMP-certified facility operating under FDA dietary supplement regulations 21 CFR Part 111 and Part 117. We keep the specific facility confidential as a matter of supplier policy. The fact that the work is US-based, the cGMP certification, and the third-party lab testing are all verifiable independently and on request.
Is the facility cGMP certified?
Yes. cGMP stands for current Good Manufacturing Practices, the FDA's quality framework for dietary supplements under 21 CFR Part 111. The facility holds a current third-party cGMP audit. We can share the certificate scope and expiration date on request to support@30base.com.
Is 30BASE Cognitive Stack FDA-registered or FDA-approved?
FDA does not register or approve dietary supplement products themselves. What FDA does is regulate the facilities that make them. The facility we use is FDA-compliant under 21 CFR Part 111 and Part 117 and is subject to periodic FDA inspections. We do not claim FDA approval, because no dietary supplement on the US market legitimately can.
Is each ingredient tested for purity and potency?
Yes. Each finished compound is tested by ISO/IEC 17025 accredited third-party laboratories on a skip-lot sampling basis. ISO/IEC 17025 is the international accreditation standard for testing-lab competence, which means the labs themselves are independently audited against it. We do not run the tests in-house, by design.
Can I see the Certificate of Analysis?
Yes. A Certificate of Analysis is available on request for every compound in the stack: Tyrosine, Taurine, Theanine, NAC, Rhodiola, Omega-3, Methyl B-Complex. Email support@30base.com with the compound name and we send the most recent CoA back. We do not publish CoAs publicly because lot numbers rotate and a stale public PDF is worse than no PDF.
Is each sachet verified for accuracy?
Yes. Every sachet, not every batch. An inline machine-vision system content-verifies each individual sachet as it is filled and sealed. Any anomaly the vision system flags is reviewed by human QC before the sachet leaves the line. This is per-unit verification, above the per-lot sampling that is standard for the category.
What about allergens?
The stack contains fish (in the Omega-3 softgel) and rice (in the Methyl B-Complex). It is free of dairy, wheat, soy, peanut, tree nut, egg, shellfish, sesame, and gluten. It is free of GMOs and contains no artificial colors, flavors, or preservatives. Full ingredient and allergen panel is on the Supplement Facts panel on every box.
