Halfday’s Crisp Apple Tea Has 6 Grams of Fiber From Three Sources. The Blend Quietly Changed, and the Can Doesn’t Print the Split
The prebiotic iced tea’s fall flavour is on Amazon now and lands in Walmart on October 1. Its fiber blend is not the one Halfday’s website still describes: acacia has replaced “fructan fiber,” which on the evidence is a gentler choice. What the can has never said is how 6 grams divides among three fibers, and the arithmetic of the ingredient list puts two of them under every dose that has been tested.
Halfday Crisp Apple Tea, a seasonal non-carbonated prebiotic iced tea launched September 16, 2026 on Amazon ($29.88 per 12, about $2.49 a can) with a national in-store Walmart launch announced for October 1, contains per 12 fl oz can 40 calories, 55 mg sodium, 13 g carbohydrate, 6 g dietary fiber (21% DV), 5 g sugars (all added) and 50 mg caffeine from black tea. Ingredients: brewed organic black tea, GOODDAY Prebiotic Blend (cassava root fiber, acacia fiber, organic agave inulin), organic raw cane sugar, apple juice powder, malic acid, ascorbic acid, natural flavors, French grey sea salt, stevia leaf extract. Halfday's website and its seven older flavours describe the blend as cassava root fiber, fructan fiber and agave inulin; Crisp Apple and a new Watermelon Half & Half list acacia instead of fructan fiber, an unannounced change. Acacia is among the best-tolerated fibers studied (low symptom scores at single 20 and 40 g doses), whereas short-chain fructans raised GI symptoms at 10 g. Halfday does not disclose the split. If the blend is listed in descending order by weight, acacia cannot exceed 3 g and agave inulin cannot exceed 2 g; acacia's prebiotic trial tested 5 to 40 g a day (optimum around 10 g) and the agave inulin trials used 5 and 7.5 g a day. Cassava root fiber is not defined by the brand; another company describes its own cassava ingredient as resistant dextrin. A proposed class action filed in February 2026 alleges 6 g per can is too little to support gut health; those are untested allegations. Olipop's shelf-stable Crisp Apple matches it at 40 calories and 6 g fiber with 1 g added sugar. Educational, not medical advice.
Halfday makes iced tea in a can for people who grew up on the gas-station kind and would like a version with a fifth of the sugar. Its founders, Mike Lombardo and Kayvon Jahanbakhsh, started brewing after Jahanbakhsh spent three months in hospital with ulcerative colitis, and the brand has grown on a simple formula: real brewed tea, no carbonation, a few grams of cane sugar, and 6 grams of what it calls its GOODDAY prebiotic blend. On September 16 it added a seasonal flavour, Crisp Apple Tea, on Amazon now at $29.88 for twelve, with “a national in-store launch at Walmart on October 1” and a list of regional grocers from H-E-B to Wegmans to follow. The top of the can reads “Supports Gut Health.”
We read the label closely, and found something nobody seems to have noticed: the fiber blend in this can is not the one Halfday’s own website describes. One of its three fibers has been swapped. The new one is, on the evidence, a gentler choice. But the swap sharpens a question the can has never answered, which is how those 6 grams divide among three very different ingredients, because the arithmetic of the ingredient list says two of them are present at well under the doses anyone has tested.
The panelWhat one can contains
The Nutrition Facts for this flavour appear on the brand’s Amazon listing. Per 12-ounce can: 40 calories, no fat, 55 milligrams of sodium, 13 grams of carbohydrate, 6 grams of dietary fiber (21 percent of the Daily Value), 5 grams of sugars, all of them added, no protein, and a line under the panel stating 50 milligrams of natural caffeine from black tea. The ingredients: brewed organic black tea, the GOODDAY blend (cassava root fiber, acacia fiber, organic agave inulin), organic raw cane sugar, apple juice powder, malic acid, ascorbic acid, natural flavors, French grey sea salt and stevia leaf extract.
Anyone who has read our Trader Joe’s apple soda piece will recognise the neighbourhood. Olipop sells a drink also called Crisp Apple in two versions, and its shelf-stable can is nearly this tea’s twin on paper: 40 calories, 13 grams of carbohydrate, 6 grams of fiber, 5 grams of sugars. The differences are that Olipop declares 1 gram of its sugar as added, against Halfday’s 5, that it is carbonated, and that it has no caffeine. Its refrigerated version carries 9 grams of fiber; Halfday has two thirds of that.
The blendOne fiber out, one fiber in
Halfday’s “Why Halfday” page and its FAQ describe the GOODDAY blend as “cassava root fiber, fructan fiber, and organic agave inulin,” and that is what the seven older flavours list. Crisp Apple, and a Watermelon Half & Half that appeared on September 1, list acacia fiber where fructan fiber used to be. The site does not mention the change or explain acacia anywhere.
On tolerance, it reads as an upgrade. “Fructan fiber” is the inulin family, the fast-fermenting group that produces the most gas per gram; a University of Minnesota trial found 10 grams of a short-chain fructan “substantially increased GI symptoms.” Acacia gum sits at the other end. In a 2021 study of 48 healthy adults, single doses of 20 and even 40 grams produced symptom scores that were “all low.” Replacing a second fructan with acacia should make the can easier on people who find inulin drinks uncomfortable. We can say that fiber by fiber; no study has compared blends with single fibers head to head, so “three fibers are better than one,” as the FAQ puts it, is a belief rather than a result.
| Fiber in the blend | Most one can could hold* | Doses used in human trials | What those trials found |
|---|---|---|---|
| Cassava root fiber (listed first) | up to 6 g | not defined by the brand, so no trial can be matched to it | — |
| Acacia fiber (second) | no more than 3 g | 5 to 40 g a day; single doses of 20 and 40 g | bifidobacteria rose, “optimal dose… around 10 g”; symptom scores “all low” |
| Organic agave inulin (third) | no more than 2 g | 5 and 7.5 g a day | bifidobacteria up three- to four-fold; slight bloating and gas, no diarrhea |
The splitSix grams, three ways
Here is the part the can does not print. If the blend’s three fibers are listed the way ingredient lists normally are, in descending order by weight, then the third, agave inulin, can be no more than a third of the total: 2 grams. The agave inulin trial that measured tolerance, and its companion paper that found bifidobacteria rising three- to four-fold, used 5 and 7.5 grams a day; two of its authors worked for an inulin supplier. Two grams is at most 40 percent of the lower dose. The second fiber, acacia, can be no more than half: 3 grams. The trial that made acacia a prebiotic, led by an author from a company that sells it, tested 5 to 40 grams a day and put the optimum “around 10.” Three grams is below the lowest dose it tried.
If the blend is listed by weight, the can holds at most 2 grams of agave inulin and 3 of acacia. The trials behind those fibers started at 5.
That leaves cassava root fiber carrying the blend, and it is the one ingredient of the three that cannot be looked up. Halfday calls it “a prebiotic powerhouse” without saying what it is chemically. Olipop, which uses an ingredient of the same name, describes its own as resistant dextrin; if Halfday’s is the same, the news is good on comfort, since a Dutch trial of a resistant dextrin saw flatulence rise only from 30 grams a day and no diarrhea at any dose. But that is an inference from another company’s page, not something Halfday has said. All three fibers may be counted on a label under the FDA’s interim list, which names resistant dextrin, acacia and inulin; none of that turns on the word prebiotic, which the agency does not define.
None of this means the 6 grams is idle. Fermentable fiber is fermentable fiber, 6 grams is a fifth of a day’s target, and most Americans fall short. It means that “Supports Gut Health” rests on the total rather than on any ingredient at a dose shown to do something. That is also, roughly, the argument of a proposed class action filed against Halfday in February, which alleges that 6 grams a can is too little to deliver the promised benefit. Those are allegations, untested in court, and we take no view of them; one of the complaint’s readings of the agave research is more pessimistic than the published abstract, which reported a clear rise in bifidobacteria at 5 grams. The number that would settle most of it is the one missing from the can: grams per fiber.

The teaFifty milligrams of caffeine, and no bubbles
Two smaller claims are worth a sentence each. The listing promises “none of the bubbles or the bloat,” and being still is a real point of difference from the prebiotic sodas, though as we found when we looked at the carbonation trials, fizz changes how full the stomach feels more than it causes lasting bloating. And the 50 milligrams of caffeine is about half a cup of coffee. The classic experiments on coffee and the colon, one using 150 milligrams of caffeine and one from 1990, found that coffee stimulates the lower bowel in many people and that decaf did much the same, so caffeine is not the whole story and a third of that dose in tea is unlikely to move anything on its own.
As a drink, this is an easy one to like: 40 calories, 5 grams of sugar where the brand’s own comparison puts a regular iced tea at 25 or more, real tea, and a fiber blend that just got gentler. As a gut-health product it is a modest 6 grams whose most interesting detail is undisclosed. Our fiber calculator will tell you how much of your day that covers. Halfday had no involvement in this article, which is educational, describes what the cited labels, pages and trials say as of September 18, 2026, and is not medical advice.
