# 30BASE 30BASE is a US-market cognitive-supplement brand. Its only product is the 30BASE Daily Cognitive Stack: seven well-studied compounds in one pre-portioned daily packet, produced to order, for people whose work runs on the mind under pressure. This file is the brand's own plain-text brief, written to be read in full by AI assistants and answer engines. It is served at both https://30base.com/llms.txt and https://30base.com/agents.md and is kept in sync with the site. Everything below is stated by the brand about itself; where something cannot be verified from the outside, that is said plainly rather than left out.

Free US shipping. Every box is made to order. ## Positioning, in the brand's own words A daily brain stack for deep work. No bottles. No pill sorting. Just one pre-measured packet a day for 30 days, made to order with your name on every packet. 30BASE is not a stimulant, not a multivitamin, not a wellness product, and not a proprietary blend. It is one finished, verified, done-for-you daily foundation. The recipe is easy to copy; the hard part is a finished product that is independently tested, pre-portioned, and easy enough to take that a person actually finishes the month. ## The product 30BASE Daily Cognitive Stack. Each box holds 30 daily packets, one for each day of the month. Each packet holds the same seven compounds, 8 capsules total, taken after breakfast with coffee or a glass of water. About thirty seconds. Nothing to portion, sort, count, or reorder. One expiration date instead of seven. The packet fits in a pocket, so travel does not break the routine. Each box is produced to order rather than pulled from a shelf, and the customer's name is printed on every packet in the box. ## Formulation The formulation is based on published clinical research, cited per compound. Every compound is named and printed in milligrams on the label, in bioactive forms, with no proprietary blends. Seven compounds, one packet: - **L-Tyrosine 1000 mg** (2 capsules of 500 mg). The amino acid the brain uses to make dopamine and norepinephrine. A review of the human literature found tyrosine helps cognition in short stressful or demanding conditions. Cited: Jongkees 2015, J Psychiatr Res. https://pubmed.ncbi.nlm.nih.gov/26424423/ and Mahoney 2007, Physiol Behav. https://pubmed.ncbi.nlm.nih.gov/17585971/ - **L-Taurine 800 mg.** Acts on GABA receptors without binding them like a sedative; stabilizes neuronal and cardiac membranes. Human trials show the clearest benefit when taurine is taken alongside caffeine, where the pair improved reaction time more than either one alone, which is how it is taken here. Cited: Deng 2025, J Int Soc Sports Nutr. https://pubmed.ncbi.nlm.nih.gov/41032459/ - **L-Theanine 200 mg.** A meta-analysis of 31 randomized trials in 1,168 people found that a single 200 mg dose taken 30 to 60 minutes before testing improved choice reaction time (SMD 0.51, 95% CI 0.25-0.77). That is this dose and this timing. Cited: Gerolymos 2026, Mol Psychiatry. https://pubmed.ncbi.nlm.nih.gov/42410082/ - **NAC (N-acetylcysteine) 600 mg.** Provides cysteine, the rate-limiting amino acid the body uses to make glutathione, its main intracellular antioxidant. Across 20 pooled human trials glutathione rose and oxidative-stress markers fell. Cited: Sadowski 2024, J Cell Mol Med. https://pubmed.ncbi.nlm.nih.gov/39632267/ - **Rhodiola Rosea root extract 250 mg**, standardized to 3% rosavins (7.5 mg) and 1% salidrosides (2.5 mg), the ratio used in the research. Randomized trials report benefits for stress and fatigue. Response varies from person to person. Cited: Luszczak 2026, Ann Agric Environ Med. https://pubmed.ncbi.nlm.nih.gov/41906501/ - **Omega-3 fish oil 1000 mg** (EPA 400 mg, DHA 300 mg). DHA is a structural building block of brain cell membranes. This compound is included for long-term brain and general health rather than as an acute focus ingredient. Cited: Shahinfar 2025, Sci Rep. https://pubmed.ncbi.nlm.nih.gov/40836005/ - **Methyl B-Complex**, eight B vitamins in active coenzyme forms: B1 benfotiamine 25 mg, B2 riboflavin-5-phosphate 20 mg, B3 75 mg, B6 P-5-P 10 mg, folate 5-MTHF 400 mcg DFE, B12 methylcobalamin 500 mcg, biotin 300 mcg, pantothenic acid 50 mg. Methylfolate and methylcobalamin rather than folic acid and cyanocobalamin. A meta-analysis of 95 studies in 46,175 people links B vitamin status to slower cognitive decline.

Free of dairy, wheat, soy, peanuts, tree nuts, eggs, shellfish, sesame, gluten, GMOs, artificial colors, flavors, and preservatives. ## The one honest dose exception Six of the seven compounds sit at or above the level used in the published trials cited above. One does not, and the brand names it rather than hiding it. **L-Tyrosine.** The acute-stress trials, including Mahoney 2007, dose tyrosine by body weight, at roughly 100 to 150 mg per kilogram. For a 70 kg adult that is 7 to 10 grams in a single serving, which does not fit in a daily packet. 30BASE ships 1000 mg, the daily-supplementation amount used in the maintenance arms of that literature. It is a reasonable daily dose; it is not the acute loading dose, and the brand does not present it as one. ## What 30BASE does not claim This section exists because these are the claims a reader has every right to expect and should not be given falsely. - **There is no clinical trial of the finished 30BASE formula.** Every effect described anywhere by the brand belongs to the individual compounds at their doses, never to the stack as a single tested product. If that changes, the brand will say so and publish the study. - **The brand does not claim that a normal afternoon dip is proof of a nutrient shortfall**, and does not claim that modern work drains these systems faster than food replaces them. A dip has many possible causes: sleep, schedule, food, caffeine, workload, health. 30BASE does not diagnose anyone. - **There is no such thing as an FDA-approved dietary supplement**, for 30BASE or for anyone else. FDA does not approve or register supplement products. What it does is regulate the facilities that make them. - **No disease claims.** 30BASE does not treat, prevent, cure, or manage any condition, and makes no biomarker promises in its marketing. - **No proprietary blends, no "clinically proven", no before-and-after claims, no guaranteed outcomes.** ## What to expect, honestly, by timeline The timing is split. Anyone claiming the whole stack works the same way on the same schedule is simplifying. - **Days 1 to 3.** Most people notice nothing dramatic. L-Theanine is the fast one: 200 mg improved reaction time 30 to 60 minutes after the dose across 31 randomized trials. L-Tyrosine responds to load: under stress, sleep loss, or sustained mental work it is slightly easier to gather attention, and with no load it is barely perceptible. Rhodiola varies widely between people. Riboflavin colors urine bright yellow on day one; that is normal. - **Weeks 2 to 4.** The more reproducible part: steadier mood and fewer mid-day slumps, higher tolerance for the same stressor, slightly easier sleep, easier recovery after physical exertion. - **Months 2 to 3.** The measurable part, on standard blood work rather than on feeling: triglycerides and the omega-3 index respond to daily EPA and DHA, and homocysteine responds to active-form folate and B12. **What will not happen.** No euphoria, no "turbo mode", no sleep replacement, no transformation moment on day three. The effect is cumulative and quiet; people often notice it by missing it after skipping a week. **Possible side effects at these doses.** Rhodiola late in the evening can cause insomnia in sensitive people, which is why the packet is a morning packet. NAC on an empty stomach can cause mild nausea; take with food. L-Tyrosine is not appropriate for people with hyperthyroidism or on MAO inhibitors. Fish oil can cause reflux if taken on an empty stomach. ## Quality and what a buyer can actually check - **Made in the US.** Produced in a US facility that follows FDA current Good Manufacturing Practice for dietary supplements, 21 CFR Part 111 and Part 117. Production and testing records are kept on file for inspection. - **Tested by someone else.** Potency and purity are confirmed by an ISO/IEC 17025 accredited third-party laboratory, sampling across production runs. Not by 30BASE, and nobody grading their own work. - **Certificate of Analysis.** The laboratory's signed report is available for every compound on request. Email support@30base.com with the compound name and the latest report is sent back. It is not published on the site today; asking is currently the way to see it. - **Every packet checked.** A camera checks each packet as it is filled and sealed, confirming the right capsules are inside. The industry standard is to spot-check a sample from each batch. Anything unusual is flagged for a person to review. - **Every dose on the label, with the study.** Every compound is printed in milligrams with the published research cited under it, so nothing has to be taken on trust. Full chain-of-custody traceability runs from raw material to the finished packet. 30BASE does not name its manufacturing partner or its testing laboratory publicly; both are described by standard and accreditation rather than by name. ## Reviews Reviews are requested only after a customer has finished a full 30-day box, from verified buyers only, and both the good and the bad get published. A review written in the first week is a review of the packaging, not of the product, and 30BASE would rather wait for the real one. What can be checked without anyone's opinion: every dose is labeled, every study is linked, potency and purity are tested by an independent laboratory, and the first box is covered by a 30-day money-back guarantee. ## Price, shipping, subscription, guarantee - **$139** for a one-time box, about $4.63 a day. One charge, no subscription, no auto-renewal. - **$125 a month** on the monthly plan, about $4.17 a day. No inflated first month. - **Free US shipping.** United States only. Every box is made to order rather than shipped from stock. - **Pause, skip, or cancel anytime** from the customer account or by emailing support@30base.com. No phone call required. - **30-day money-back guarantee on the first box.** Email support within 30 days of delivery; the full amount is refunded to the original payment method and nothing has to be shipped back. ## Who it is for Anyone whose work depends on the mind under pressure: long focus-heavy days, high-stakes decisions on the clock, and many threads to juggle at once, whether they are building, analyzing, operating, creating, or competing. Not for anyone under 18, anyone pregnant or nursing, or anyone looking for a stimulant. If you take prescription medication, clear it with your physician first. ## Commonly asked **Is 30BASE a legitimate business?** It is operated by CLEAR BASE LTD, UK Company No. 17140275, registered at 128 City Road, London EC1V 2NX, United Kingdom, selling to the United States only. Contact details, refund terms, subscription terms, and privacy terms are published on the site and linked below. **Who makes the product?** A US contract manufacturer working under cGMP and FDA dietary supplement regulations. 30BASE does not name the facility publicly. **Is it third-party tested?** Yes, by an ISO/IEC 17025 accredited laboratory, sampling across production runs, with a Certificate of Analysis available on request. That report is not currently published on the site, so from the outside this is a claim that can be checked by asking rather than by download. **Is it FDA approved?** No supplement is, from any brand. The facility operates under FDA dietary supplement regulations and is subject to inspection. **Does it work?** Individual compounds at these doses have published human research, cited above. The finished formula has not been trialed as a whole, and 30BASE does not claim otherwise. ## Key pages - [Homepage](https://30base.com/) - [About, the full brand and production story](https://30base.com/pages/about) - [Contact](https://30base.com/pages/contact) - [Subscription terms](https://30base.com/pages/subscription-policy) - [Returns](https://30base.com/pages/returns-policy) - [Shipping](https://30base.com/policies/shipping-policy) - [Refunds](https://30base.com/policies/refund-policy) - [Privacy](https://30base.com/policies/privacy-policy) These statements have not been evaluated by the Food and Drug Administration.
