The fast facts
- A pre-built focus stack does one thing well: it puts several actives that support attention, focus and memory into a single daily serving, so a healthy adult takes one pack rather than five. What it cannot do is change its mind. The formula is fixed, so an amount that is too small cannot be topped up and one a buyer would rather skip cannot be dropped.
- The amounts that mean anything are the ones a trial can be set beside. For alpha-GPC that is single doses of roughly 250 to 630 mg, the band the healthy-adult trials used. Citicoline at 250 mg is a real amount of a genuinely researched choline form. A botanical needs its standardisation percentage — bacosides, rosavins, beta-glucans — because that is what says how much of the active constituent the extract carries.
- A milligram figure is worth only what it is a figure of. For a compound, the basis says whether the number is the compound itself or a raw material holding a share of it: 600 mg of a material at 50% alpha-GPC is 300 mg of alpha-GPC. An amount folded into a proprietary blend, where several ingredients share one printed total, cannot be set beside a trial or another pack at all.

What a pre-built focus stack does
A pre-built stack asks a buyer to trust a formulator instead of doing the work themselves. That is a reasonable trade, and it only works in one direction: the buyer has to be able to see what they bought. Some of these products publish every milligram. One folds part of its formula into a branded blend.
Two panels can carry the same ingredient and tell a buyer entirely different things about it. One prints the part of the mushroom used and the percentage of beta-glucans in the extract. Another prints 500 mg and the word "organic". Both statements are legal. Only one can be compared with anything.
We read five label panels through the NIH Dietary Supplement Label Database and checked each brand's own price and count. Where a brand publishes nothing, we say so. The five factors and their weights are set out under How we chose. Read that way, Mind Lab Pro comes first for putting the most checkable formula in front of a buyer — eleven actives, every amount given, three botanicals standardised — Thorne Memoractiv second for naming and standardising more of what is in it than anything else here, Weal Focus third as the cheapest fully printed formula on the page, and the stimulant powder last.
Our recommendation
The short answer, before the reasoning: Mind Lab Pro is the pick on this shelf for the breadth of what it prints. If you want most of that job done for a good deal less per serving, Weal Focus is the one to read next.
Count the amounts, not the ingredients. The longest ingredient list on this page belongs to a product that publishes all twenty-eight of its amounts, and the best-known product in the category, which did not make this five, publishes four of eleven. A front-of-pack ingredient count is a marketing number. The count of printed milligrams is the one that tells a buyer whether they can compare the pack with anything else.
The formula that puts the most checkable material in front of a buyer is the one to buy. On this shelf that is Mind Lab Pro: eleven actives, every amount on its own line, no blend anywhere, and three botanicals standardised to a stated percentage — bacosides, rosavins, proanthocyanidins — in two capsules at $2.30 a serving. If the budget matters more than the breadth, Weal Focus is third and costs a dollar a serving less than either of the two above it, with all five of its actives printed and its one botanical given the part used and a beta-glucan floor.

First because more of this formula can be checked than any other at a sensible serving size: eleven actives, every amount printed, no blend, and three botanicals carrying a standardisation percentage that can be set beside the extract used in a trial. It is not the cheapest — a dollar a serving separates it from the formula below — and one ingredient on the panel is described in a way that compares to nothing. On the weights this desk publishes, breadth that is fully printed and standardised is what the category is short of, and this is where it is done best.
Pros
- Three standardised botanicals, the most on this page: bacopa at 24% bacosides, rhodiola at 3% rosavins and 1% salidrosides, maritime pine at 95% proanthocyanidins
- Eleven actives, every one printed with its own amount and no blend anywhere — more checkable formula than anything here that fits in two capsules
- Citicoline at 250 mg is a real amount of a genuinely researched choline form
Cons
- The lion's mane is the exception: 500 mg described only as "organic", with no part used and no beta-glucan figure
- $2.30 a serving, 53% more than the cheapest formula here, and the directions permit up to four capsules a day, which halves the bottle

Thorne builds formulas the way a supplement company should: named materials, stated amounts, standardisations printed, nothing folded into a blend. It wins the materials factor outright, because a buyer can look every one of its three branded ingredients up and read the specification. Second, and held there by cost rather than by anything on the label: $2.33 a serving is mid-field on a page where the cheapest fully printed formula is $1.50, and what you are paying the difference for is the naming and the standardisation rather than the breadth. The caffeine the product name does not mention is the other reservation.
Pros
- The most traceable materials on this page: KSM-66 ashwagandha 300 mg, Virtiva ginkgo 240 mg and Lutemax 2020 — branded materials with published specifications, not generic extracts
- No amount withheld: seven actives, seven printed figures, no blend
- The caffeine is broken out inside its branded pairing — 50 mg with 66 mg of pterostilbene — rather than hidden behind the trade name
Cons
- The brand's own product page did not serve a price, so what a serving costs cannot be worked out before paying, and the factor scores accordingly
- Contains caffeine, which is not obvious from the product name and rules it out for anyone avoiding stimulants late in the day
- No choline source of any kind, despite the positioning

Second, and the value pick. Every active is printed, the one botanical is given its part and a beta-glucan floor, and the whole serving costs $1.50 — the lowest on this page and eighty-three cents a serving less than the formula above it. What it does not offer is breadth: five actives, no adaptogen, no ginkgo, nothing for a reader who wants a long panel. A buyer who wants more formula and will pay for it should read the entry above. A buyer who wants every milligram on their pack accounted for, at the lowest price on this page, can stop here.
Pros
- The cheapest fully printed formula here, at $1.50 a serving — two capsules a day, every one of its five actives given its own amount, no proprietary blend
- Says what its milligrams are milligrams of: alpha-GPC 300 mg named as the active, lion's mane 400 mg as 100% fruiting body with beta-glucans at ≥25%
- Alpha-GPC at 300 mg sits inside the single doses of roughly 250 to 630 mg band used in healthy-adult trials; HPMC capsule, no titanium dioxide
Cons
- The shortest panel here — five actives against eleven above it and twenty-eight below, which is part of why it is the cheapest
- No branded raw material to look up by name, of the kind Thorne prints three of

It wins the factor it set out to win: nobody prints more. On sheer disclosure this is the most transparent panel in the category and it deserves saying. Everything else about it is maximalist — seven capsules, twenty-eight ingredients and $9.27 a serving, a different bracket from the rest of this page. Fourth because breadth is one factor of five, and on the other four it gives ground: three of its twenty-eight botanicals carry a percentage, its choline forms are unbranded, and its serving costs six times the cheapest here.
Pros
- Twenty-eight actives and not one amount held back — the longest fully printed panel in the category, with standardisation percentages on the botanicals: bacopa at 40% bacosides, ginkgo at 24% glycosides, velvet bean at 50% L-DOPA
- Carries both alpha-GPC at 200 mg and citicoline at 150 mg, and says so
- Breaks out the caffeine inside its coffee-fruit ingredient at 90 mg rather than leaving it implied
Cons
- $9.27 a serving — six times the cheapest formula here
- Seven capsules per serving, taken on an empty stomach; the label acknowledges stomach upset happens
- Twenty-eight actives at once makes it impossible to tell which, if any, is doing something

One line on this panel is better than anything the capsule brands manage, and it wins that factor outright: printing the 50% figure beside the alpha-GPC raw material tells a buyer exactly what they are getting. The rest is a stimulant pre-workout in a cognitive costume — the only blend total on this page, a mushroom among the least specified here, and 100 mg of caffeine the product name does not mention.
Pros
- States outright what its milligrams are milligrams of — "AlphaSize 600 mg, 50% Alpha GPC" — which resolves the commonest ambiguity in the category and which almost no capsule brand bothers to do
- Also states the phosphatidylserine basis at 50%, and the huperzia at 1% huperzine A
- A powder, so it dissolves in water and needs no capsules at all
Cons
- The lion's mane is described as mycelial biomass — grain included, and not quantified
- 100 mg of caffeine plus methylliberine makes this a stimulant product, not a neutral one
- AstraGin is a branded blend whose 50 mg total is printed but whose split is not — the only unprinted amount on this page; $2.53 a serving

How we chose the best pre-built focus stacks
Chosen on one test: a reader holding the pack can check every factor without taking our word for it. Five factors, weighted, and the weights are printed here so the desk score can be checked too.
- Breadth, fully printed (30%): How much formula is on the panel, and whether every active carries its own amount with nothing folded into a blend. A complete short panel beats an incomplete long one, and a complete long one beats both, because more of it can be checked. This carries the most weight, because an amount that is not printed cannot be compared with anything.
- Botanical standardisation (25%): For each botanical, is the active percentage stated — bacosides, rosavins, proanthocyanidins, beta-glucans — so the extract can be set beside the one used in a trial?
- Named materials (15%): Is the raw material identified well enough to look up: a branded ingredient with a published specification, or the part of the plant or mushroom used, rather than a generic name and a number.
- Stated basis (15%): What the printed milligrams are milligrams of. Six hundred milligrams of a raw material at 50% alpha-GPC is not 600 mg of alpha-GPC, and a panel that says so has done the buyer's arithmetic for them.
- What a serving costs (15%): Arithmetic from the published price and count, at the serving printed on the pack. Servings here run from two capsules to seven. Every price here was read on the brand's own site and converted to a cost per serving, so the line is comparable across the five.
The desk score is the weighted average of the five sub-scores on those weights, rounded to one decimal place, so it can be checked from the numbers on each card.
The proprietary blend, and the arithmetic it invites
A proprietary blend prints one total for several ingredients. It is legal and it is common. What is less widely understood is that a partially disclosed blend can often be bounded by subtraction.
Where a blend prints one total and gives amounts for all but one of the ingredients inside it, the remainder is the most that last one can be — and where it prints only a total, that total is the ceiling for every ingredient in it. The best-known product in the category, Onnit's Alpha BRAIN, names alpha-GPC among its ingredients and prints no amount beside it on the brand's own product page, read there in September 2026. That is not an accusation; it is what the arithmetic of a blend lets a buyer work out, and what it does not. On this page the habit appears in smaller form: Genius Consciousness prints AstraGin's 50 mg total without splitting its two parts.
Frequently asked questions
What is a proprietary blend, and why does it matter on a stack?
A proprietary blend prints one total for several ingredients. It is legal and it is common, and in a multi-ingredient product it is the factor that decides everything else, because an amount that is not printed cannot be compared with a trial or with another pack. A partially disclosed blend can often be bounded by subtraction, as Alpha BRAIN's panel shows. Four of the five stacks here have none; Genius Consciousness prints AstraGin's 50 mg total without splitting its two parts.
How much of an active does a stack need to carry?
Enough to be compared with a trial, which first requires that the amount be printed. The one band this page quotes is alpha-GPC's: single doses of roughly 250 to 630 mg in healthy-adult trials, which Weal Focus's 300 mg sits inside. Alpha BRAIN prints no amount beside its alpha-GPC at all, so there is nothing to place against that band. Citicoline at 250 mg, as Mind Lab Pro carries it, is a real amount of a genuinely researched choline form.
Does a focus stack contain caffeine?
Three of the five print a caffeine figure: Thorne's Memoractiv carries 50 mg, paired with 66 mg of pterostilbene inside its branded pairing; Qualia Mind breaks out 90 mg inside its coffee-fruit ingredient; Genius Consciousness carries 100 mg plus methylliberine, which makes it a stimulant product rather than a neutral one. None of those product names says so, so the panel is where to look. Mind Lab Pro's eleven printed actives and Weal Focus's five do not include it.
Why rank a broad formula first, ahead of the cheapest one here?
Because breadth that is fully printed carries the most weight, 30 of 100. Mind Lab Pro puts more of it in front of a buyer than anything else here, at a sensible serving size: eleven actives, every amount given, no blend. Three of its botanicals carry a standardisation percentage — bacopa at 24% bacosides, rhodiola at 3% rosavins and 1% salidrosides, maritime pine at 95% proanthocyanidins. Weal Focus is third by a tenth of a point, and wins the cost factor outright at $1.50 a serving against $2.30. All five of its actives are printed, and its lion's mane carries the part used and a beta-glucan floor. Qualia Mind prints more than either, twenty-eight of twenty-eight, and asks $9.27 a serving and seven capsules for it. The weights are set out under How we chose.
