Scan the ingredient panel on almost any generic "brain blend" or all-in-one multivitamin marketed for focus, and you'll often see familiar names — bacopa, alpha GPC, L-theanine, ginkgo. On paper it can look similar to Cognitive Support. The real differences aren't always visible from the ingredient list alone, and one of them is a structural quirk of U.S. supplement law that's worth understanding before you compare any two products by their label.
The proprietary blend problem
Under the Dietary Supplement Health and Education Act of 1994, a company can group several ingredients into a "proprietary blend" and legally disclose only the blend's total weight and the names of the ingredients inside it — not how much of each ingredient is actually in there.1 A 2023 peer-reviewed analysis in The Journal of Nutrition lays this out plainly: this practice, intended to protect trade secrets, means the amount of any single ingredient in a proprietary blend often isn't available for calculating real-world exposure or comparing it to the dose used in clinical trials.1 In plain terms: a "brain blend" can list bacopa monnieri on the front of the bottle without you ever being able to confirm whether it's dosed anywhere near what the human trials for bacopa actually used, or present at a token amount.
A proprietary blend can legally list an ingredient's name without ever telling you how much of it is actually in the capsule.
What the regulation actually requires — and the one thing it gives you
The mechanics live in 21 CFR 101.36, the rule that governs the Supplement Facts panel. For a proprietary blend, the manufacturer must print the total quantity of the blend by weight, and must list the dietary ingredients inside it in descending order of predominance by weight. It does not have to print the individual quantities. That is the whole of the concession, and it is why blends are so common: the formulator gets to keep the recipe while still satisfying the panel.
The descending-order requirement is the one lever a reader has. It means the blend list is a ranking, not an alphabetical or marketing order. Whatever is named last in a blend is the smallest component of it. Combined with the blend total, that gives you a hard mathematical ceiling for every ingredient in the list — and in a lot of cases the ceiling alone settles the question.
Where Cognitive Support actually stands
Cognitive Support uses a proprietary blend. Its Supplement Facts panel lists niacin at 8mg NE and vitamin B6 at 5mg, each with its own figure — and then a single line reading Proprietary Blend, 255mg, containing GABA, L-tyrosine, caffeine, bacopa monnieri, phosphatidylserine, alpha GPC, L-theanine and huperzine A. Eight of the ten actives sit inside that number — those two vitamins are the only ones individually dosed. You cannot tell from the label how much caffeine is in a capsule, or whether the bacopa is anywhere near a trial dose.
Apply the ceiling arithmetic to our own product and it gets uncomfortable fast. Eight ingredients share 255mg — an average of roughly 32mg each, with 255mg as the absolute maximum for any single one. Bacopa monnieri's cognitive trials have overwhelmingly used around 300mg a day of a standardised extract over twelve weeks or more, a figure we go through in our bacopa write-up. The entire blend is smaller than that one trial dose. So without knowing a single individual number, we can already say the bacopa in Cognitive Support is below the dose the evidence was built on. The same logic squeezes phosphatidylserine, studied at 100–300mg a day, and alpha GPC, whose cognitive literature sits in the hundreds of milligrams. Caffeine and L-theanine could plausibly be at studied amounts inside 255mg; nothing on the label confirms it.
That is the same structure this article has just finished criticising, and we are not going to pretend otherwise. Two things are worth saying alongside it. First, every ingredient inside the blend is named on the panel — nothing is hidden behind an unlisted "proprietary complex," which is a worse version of the same practice and is common in this category. Second, we asked. We went to our manufacturer directly in September 2026 for the per-ingredient breakdown, and the individual milligram amounts for that blend are not available to publish. That is an honest limit on the current formula, not a timeline we can promise our way out of.
Where we can make the stronger claim, we do: Sleep Formula discloses all seven of its ingredients with individual doses on the label. That is one product, not the range, and stating it as a range-wide standard would be the same mistake this correction is fixing. Sleep Support, in the same category, runs a 905mg blend of fourteen botanicals — which is a bigger undisclosed number than Cognitive Support's.
A generic multivitamin is solving a different problem entirely
Separately from the blend-disclosure issue, a standard multivitamin marketed with "brain support" language is usually built around RDA-level doses of vitamins and minerals — amounts calibrated to prevent a nutrient deficiency, not to hit the specific, higher doses used in the human trials for a targeted nootropic ingredient like bacopa monnieri or alpha GPC. Taking a multivitamin doesn't substitute for an ingredient dosed to the range a clinical trial actually tested; it's solving for "not deficient," not "cognitive performance under demand."
Cost per day, and why it tells you least
Cognitive Support is $29.90 for 30 single-capsule servings — a round $1.00 a day, cheap for this category, and a generic high-street brain blend is often cheaper still. Neither figure means much, because what you are buying is milligrams of something studied. A $1.00 capsule with a token amount of bacopa is worse value than a $2.00 capsule with 300mg of it, and a blend label makes that sum impossible to run. Price per day is the easiest number to compare and the least informative one, which is roughly why it headlines so many comparison pages.
Third-party testing: a claim and a certificate are different things
"Third-party tested" is a phrase, not a programme. It becomes meaningful when a named certifier with a public, searchable registry stands behind it — NSF Certified for Sport and Informed Sport are the two most common here, and some nootropic competitors carry them. Proco publishes batch certificates of analysis on request rather than carrying a certification mark, which is a weaker position, and we would rather say so than let the phrase do work it hasn't earned. Our guide to reading a COA sets out what the document proves.
What to actually check when comparing two products
Three questions cut through most of the marketing noise, regardless of brand: does the label group ingredients into an undisclosed "proprietary blend," or list them individually? Is each named ingredient backed by multiple independent human trials, not a single small or industry-funded study? And where a dose is disclosed, does it match what those trials actually used, or is it a fraction of it? Our fuller breakdown of how to read a label for exactly this covers the mechanics in more detail.2
Apply those three questions to us as readily as to anyone else. On the first, Cognitive Support gives a partial answer and Sleep Formula a complete one. On the second, the individual ingredients hold up. On the third, Cognitive Support cannot answer at all, and the ceiling arithmetic above suggests the answer would not flatter it. A comparison article that came out flattering to the company publishing it would be worth less than one that doesn't. If you would rather buy the ingredients separately at doses you can read, that is a legitimate conclusion, and the trade-offs are in Cognitive Support vs. stacking your own and single-ingredient vs. blend. Which blends we will and won't sell at all is in why we don't sell "brain blends".
