Tonic Health Creatine + Brain vs Creatonics Day and Night: two 10-gram bets on one number

Ten grams is the whole argument. Creatine has spent decades as a five-gram scoop in the strength aisle, and two products launched this month have moved it to the cognition aisle by doubling that and printing a reason on the front. NutraIngredients’ new-product round-up of 27 August, written by Nikki Hancocks, carries both: Tonic Health’s Creatine + Brain and the Creatonics day-and-night bundle.

Every figure below comes from that report. No physical label was consulted for either product, so treat the numbers as reported rather than confirmed.

What is published

Two brain-marketed creatine launches, as reported at launch

Tonic Health, per scoop	Micronized creatine monohydrate 10,000 mg, which the brand calls 'ultra-pure' 99.9 percent; taurine 2,000 mg; biotin 1,000 mcg; concentrated blueberry extract 800 mg
Tonic Health, format	One daily scoop, raspberry or tropical
Creatonics, structure	10 g of micronized creatine split across a day product and a night product, sold as a bundle; how the 10 g divides is not stated
Creatonics, day side	Creatine, share unstated, plus Zensera lemon balm, vitamin D3, vitamin K2, methylated B vitamins; unflavoured or lemon; no doses for the added four
Creatonics, night side	Creatine, share unstated, plus magnesium glycinate, zinc, cocoa, SheVari4 shatavari; unflavoured or cocoa; no doses for the added four
Prices and servings	Not stated in the trade report for either product
Source of figures	NutraIngredients new-product round-up, 27 August 2026; no label consulted

Where the ten grams comes from

Creatonics puts the reasoning on the record. Muscle takes up creatine greedily, its founder Chris Curwen told the outlet, and only once that demand is met does the brain get a share — which is why, on his account, cognitive effects “only start” at ten grams a day. A tidy story, and a testable one — but at present a story rather than a finding.

The pooled literature does not draw that line. The 2024 systematic review and meta-analysis in Frontiers in Nutrition by Xu and colleagues gathered 16 randomised controlled trials and 492 adults aged roughly 21 to 76. Doses ran from 3 to 20 grams a day, with some trials dosing by bodyweight at 0.3 g per kilogram instead, durations from seven days to eighteen months, and thirteen of the sixteen studies were in healthy adults. Nowhere in that spread does a ten-gram threshold appear as the point where effects switch on.

What the review found is narrower than the marketing suggests. Memory improved on the pooled estimate; attention time and processing-speed time both shortened; executive function and overall cognition showed no significant effect. The paper’s 2025 corrigendum spells out the other half of the picture: on attention scores, four studies and 128 participants produced nothing significant, and on processing-speed scores, four studies and 104 participants produced nothing either. The gains sit in how fast people responded, not in how well they scored, and the authors flag small samples and heterogeneous designs.

None of which makes creatine a bad ingredient. It makes ten grams a hypothesis with a product attached.

Tonic Health: four ingredients, all of them visible

The Creatine + Brain panel is the more honest document of the two, simply because it exists. Ten thousand milligrams of monohydrate, stated to the milligram, with a purity figure attached — 99.9 percent, the brand’s own claim rather than an independent assay. Two grams of taurine. That is a formula you can hold an argument with.

The other two rows are weaker. Blueberry extract at 800 mg arrives with no standardisation reported — no anthocyanin figure, no extract ratio — which leaves it uncomparable to any published work on blueberry polyphenols. And 1,000 mcg of biotin in a cognition powder is a row without a stated reason. Biotin is a real nutrient with a real deficiency state; that is not the same as a rationale for putting a large amount of it beside creatine and calling the result a brain product.

Creatonics: a rationale without a panel

The day-and-night split is a genuine idea. Spreading ten grams across two servings is a plausible answer to tolerance, and a magnesium-and-cocoa evening serving admits that a day has a shape.

But the bundle names eight additional ingredients and publishes a dose for none of them: lemon balm, vitamin D3, K2, methylated B vitamins, magnesium glycinate, zinc, cocoa and a branded shatavari. Eight nouns, zero milligrams. An ingredient list is not a panel, and a branded extract without an amount borrows credibility from trials it may not resemble.

The ledger

Panel against panel

Pros

Tonic Health prints every dose, including the creatine to the milligram
Both use creatine monohydrate, the form carrying by far the largest published literature
Tonic Health's list is four ingredients long — short enough to argue with in full
Creatonics states a rationale for its split rather than leaving the format unexplained
Neither formula lists added caffeine, though the Creatonics night side does include cocoa

Cons

The ten-gram cognitive threshold is a founder's reasoning, not a published finding
Creatonics names eight added ingredients with no dose for any of them, and does not split its 10 g of creatine by tub
The Creatonics rationale requires buying two products to assemble one daily serving
Blueberry extract at 800 mg carries no standardisation, so it compares to nothing
Biotin at 1,000 mcg sits in a cognition formula with no published reason for being there
No price or serving count in the published material, so cost per day cannot be checked
The pooled gains are in response times; attention and processing-speed scores came out null

Verdict

The score belongs to Creatine + Brain, and it rewards disclosure more than formulation: two of its four rows are furniture, but a buyer can see what they are paying for. Creatonics cannot be scored until it publishes numbers, because a review of an ingredient list is a review of a marketing document.

Both suit someone who already takes creatine, tolerates it, and would rather not measure out the higher amount. Neither suits anyone buying on the cognition pitch alone, which is running ahead of a small and mixed evidence base. The ordinary caveats hold: these are supplements, not evaluated by the FDA, not intended to diagnose, treat, cure or prevent any disease, and doubling a daily dose is worth raising with a clinician, particularly alongside prescription medication or any existing kidney concern.
