"Supports digestion" and "promotes a diverse microbiome" on a packet describe hopes, not measurements. Three things could be measured: does eating this add useful **fiber**, does it change your **gut bacteria**, and does it **sit well with you**. Here is what has been checked on each. ## There is one human microgreen study. It is eleven people. [Researchers gave 11 healthy people 16 g of fresh broccoli microgreens, once](https://pubmed.ncbi.nlm.nih.gov/37893677/), then measured the compounds in their bodies along with a snapshot of their gut bacteria. The crop was 10 days old and it was analyzed properly: 12.8 micromoles per gram of glucoraphanin at one day after harvest, and 7.2 of sulforaphane. That is a real study and it tells you something worth knowing: the compounds get absorbed, and gut bacteria are involved in processing them. What it did not do is measure whether anything improved. No bloating, no regularity, no symptoms, no before-and-after over weeks. Eleven people, one meal. It also excluded pregnant and breastfeeding people and anyone with significant digestive disease, so it offers no reassurance about the groups most likely to be asking. **So, it is not that microgreens do nothing for your gut. The question has not been tested.** ## The constipation study, which used sprouts [Forty-eight adults with constipation](https://pubmed.ncbi.nlm.nih.gov/29371757/) took either [broccoli](https://microgreensguru.com/microgreen-types/broccoli/) or [alfalfa](https://microgreensguru.com/microgreen-types/alfalfa/) **sprouts**, 20 g a day for four weeks. The broccoli sprouts contained 4.4 mg of the precursor compound per gram. The broccoli group's constipation score improved from 7.25 to 5.17, and their score for straining improved from 0.96 to 0.58. That sounds like the answer. Three things sit next to it, all of them stated in the study itself. The bowel study, with the parts usually left out | What it found | What also needs saying | | --- | --- | | Constipation score 7.25 down to 5.17 (p = 0.0017) | Semi open-label. Participants knew what they were taking, and scored their own symptoms | | Straining score 0.96 down to 0.58 (p = 0.0077) | **Funded by a farm that sells sprouts**, with the senior author holding an industry-supported endowed chair | | | **Bifidobacterium went DOWN** (p = 0.0498), and that is one of the headline "good" bacteria | That last row matters more than the first. The study is regularly cited as evidence that these crops feed good gut bacteria, and what it actually measured was one of the headline good bacteria going the other way. It is also sprouts, not microgreens. ## The other human studies were measuring something else Human sprout studies people cite for gut health | Study | What people got | What was measured | | --- | --- | --- | | [Atwell 2015](https://pubmed.ncbi.nlm.nih.gov/25522265/), 10 people | Fresh **sprouts** against a treated extract, 200 micromoles each | Compounds in blood and urine | | [Egner 2011](https://pubmed.ncbi.nlm.nih.gov/21372038/), 50 people | Sprout **drinks**: 800 micromoles glucoraphanin, or 150 preformed sulforaphane | Compounds in urine | | [Clarke 2011](https://pubmed.ncbi.nlm.nih.gov/21816223/), 12 people | 40 g fresh **sprouts** against six supplement **pills** | Compound levels over 48 hours | None of them looked at the gut at all. Two are worth a moment for a different reason, because together they say something useful about supplements. Atwell found people absorbed **about three times more** of the compound from fresh sprouts than from a myrosinase-treated extract. Clarke found the pills delivered **less, and slower**, than the fresh plant. More concentrated does not mean more usable. Worth remembering any time a capsule is compared with a vegetable. ## How much fiber a serving actually holds This is the part specific to microgreens, and it is the reason to be careful about the whole category here. Microgreens do contain [fiber](https://pubs.acs.org/doi/10.1021/acsfoodscitech.3c00040), and it has been measured. Then the question is not what is in a gram. It is what is in a serving. Measured fiber, and what a 16 g serving works out at | Crop | Fiber per 100 g fresh | In a 16 g serving | | --- | --- | --- | | Broccoli microgreens | 0.36 g | About 0.06 g | | Radish microgreens | 1.78 g | About 0.28 g | | Mustard microgreens | 2.08 g | About 0.33 g | The left column is measured and published. The right column is our own arithmetic on it, using the 16 g serving from the human study. Adult fiber guidance is set in **tens of grams a day**. The best crop in that table, at a realistic serving, contributes a third of one gram. To get a fiber effect out of microgreens you would have to eat them by the bowl rather than the pinch, and nobody has tested whether anyone will. That is a genuine open question, not a rhetorical one, and you can settle your own version of it with a kitchen scale: weigh what actually goes on the plate and multiply. If fiber is what you are after, the crops worth growing are the ones you eat in volume. [Pea shoots](https://microgreensguru.com/go/seed-pea-shoots/) and [sunflower](https://microgreensguru.com/go/seed-sunflower/) are the two people genuinely eat by the bowl, and [sunflower](https://microgreensguru.com/microgreen-types/sunflower/) yields more per tray than any other crop in [the directory](https://microgreensguru.com/microgreen-types/). ## What fiber actually does, when it is enough of it It is worth knowing what the target looks like, because the fiber literature is much stronger than anything microgreen-specific, so it is the right benchmark. Researchers pooled [64 randomized human fiber trials](https://kclpure.kcl.ac.uk/ws/files/88429815/Dietary_fiber_intervention_on_SO_Published2018_GREEN_AAM.pdf) covering 2,099 people. Sixty-four fiber trials, pooled | Outcome | Effect | Range | Reading | | --- | --- | --- | --- | | Bifidobacterium | SMD **0.64** | 0.42 to 0.86 | A clear increase | | Lactobacillus | SMD **0.22** | 0.03 to 0.41 | A small increase | | Fecal butyrate | SMD **0.24** | 0.00 to 0.47 | Borderline. The range touches zero | | Alpha diversity | **No difference** | | The thing "a diverse microbiome" refers to did not move | Read that last row again. Sixty-four trials of actual fiber interventions, and overall diversity did not shift. The phrase "promotes a diverse microbiome" is doing work that even proper fiber studies could not do. Those were mostly concentrated prebiotic fibers, at doses far above anything a tray of microgreens delivers. It is the benchmark, not a microgreen result. ## The mechanism, and where it stops There are two proposed routes, and they have been shown to very different levels. ### The two proposed routes, and the level each step has been shown at 1. 1 #### Route one, the fiber route Fiber escapes digestion in the small intestine and reaches the colon intact. Shown in PEOPLE, well established. 2. 2 #### Bacteria ferment it into short-chain fatty acids Shown in PEOPLE, with the pooled trial results above. 3. 3 #### A microgreen serving delivers enough fiber to do that NOT SHOWN, and the arithmetic above is the reason to doubt it. 4. 4 #### Route two, the compound route Damaged plant tissue lets myrosinase convert glucosinolates into isothiocyanates such as sulforaphane. Gut microbes can do a version of the same conversion. Shown in PLANTS and in PEOPLE. 5. 5 #### The compounds reach you from a microgreen Shown in PEOPLE eating MICROGREENS, in the 11-person study. This is the strongest microgreen-specific finding that exists. 6. 6 #### Those compounds change the bacterial community Shown IN VITRO and in MICE. Not in a person eating microgreens. 7. 7 #### Symptoms or gut health change NEVER SHOWN for a microgreen. No trial has measured it. ## The mouse and test-tube work, with the numbers attached The animal studies are real and they are the reason people are interested, so they deserve to be reported accurately rather than waved at. In a 34-day colitis experiment, [mice were fed a diet containing 10 percent steamed broccoli sprouts by weight](https://pmc.ncbi.nlm.nih.gov/articles/PMC10245759/). Disease measures were lower and the geography of the gut microbial community was better preserved than in controls. A second study fed [10 percent raw broccoli sprouts](https://pmc.ncbi.nlm.nih.gov/articles/PMC9900910/) to mice bred to develop gut inflammation, and a gut inflammation marker came down. A third gave [isolated sulforaphane at 2.5 to 20 mg per kg](https://pubmed.ncbi.nlm.nih.gov/35832050/) a day. Ten percent of total food intake, of sprouts, in mice with induced disease. That is closer to a drug dose than a serving, and it cannot be converted into a human portion. The artificial-gut experiment is the one worth reading closely. Researchers ran [sulforaphane through a laboratory fermentation](https://pmc.ncbi.nlm.nih.gov/articles/PMC9778330/) with stool bacteria from people with obesity. Total short-chain fatty acids after 24 hours came out at **42.29 mM with sulforaphane against 42.12 mM without it.** Butyrate rose 1.21-fold and valerate 1.46-fold, which is the part that gets quoted. Look at the two totals. They are the same number: total fermentation did not change, even though two individual acids rose. ## The measured comparison, and why it still does not convert The microgreen study measured fresh broccoli **microgreens** at about **13 micromoles per gram** of glucoraphanin, and cited **16.6** for broccoli sprouts. That looks like a conversion factor and it is not one. The two numbers come from different crops at different growth stages measured in different studies, and how much of the precursor becomes the active compound depends on the variety, the preparation, how much you chew, whether the plant's own converting enzyme survived, and your gut bacteria. Converting a labeled dose from a sprout drink into grams of a different crop is arithmetic performed on things that are not comparable. ## Which crop, grown how, stored how long Composition is where the research is genuinely solid, and the answers are all crop-specific. A laboratory digestion model measured total isothiocyanates in four microgreens at [633, 608, 801 and 810 mg per 100 g of dry weight](https://www.mdpi.com/2304-8158/8/7/250) for broccoli, kale, mustard and radish respectively, with 31 to 63 percent of it bioaccessible. Mustard and [radish](https://microgreensguru.com/microgreen-types/radish/) carry more than broccoli does, which is the reverse of where the attention goes. That was a simulated gut, not a person. Growing conditions move the numbers. Preharvest UV-B raised total aliphatic glucosinolates in broccoli microgreens by [13.7 and 16.9 percent](https://pmc.ncbi.nlm.nih.gov/articles/PMC8197856/) at two doses. More light raises them too, up to a point: one experiment found the difference between 70 and 90 micromoles per square meter per second was no longer significant, and individual compounds moved in different directions. Storage is better news than you would expect. In the human study, glucoraphanin and sulforaphane did not differ significantly between day one and day six in the fridge. A separate storage experiment did see untreated broccoli microgreens fall from [30.10 to 24.53 micromoles per gram](https://www.mdpi.com/1420-3049/26/11/3247) of total glucosinolates over three days, so it depends on the crop and how it was handled. What none of it establishes is a link to anybody's gut. And harvest stage is open too: stage clearly changes the chemistry, with about 8 micromoles per gram of glucoraphanin reported in broccoli and about 14 of glucobrassicin in [kale](https://microgreensguru.com/microgreen-types/kale/) at their respective peaks, but the direction depends on cultivar and on which compound you are asking about. ## What about mature broccoli There are small controlled human studies on **mature broccoli** and gut bacteria, including [a randomized crossover](https://pubmed.ncbi.nlm.nih.gov/30317146/) in which 18 healthy people ate 200 g a day of cooked broccoli plus 20 g of raw daikon for 18-day periods. That is better evidence than anything that exists for microgreens. It is also 200 g of a cooked grown vegetable. Read it as evidence about broccoli, not about a 16 g portion of seedlings; swapping one for the other is the same move the next section describes. ## Three ways this claim gets ahead of its evidence ### Three ways this claim gets ahead of its evidence - #### Swapping the material Calling broccoli SPROUTS microgreens. A major health site ran a headline doing exactly this over a story about a laboratory germination study. The FDA classes them as different products. - #### Swapping the outcome Turning "sulforaphane metabolites were detected after 16 g of microgreens" into "microgreens improve your microbiome". The study measured exposure. It did not measure a symptom or a benefit. - #### Swapping the dose Treating a mouse fed 10 percent of its chow as sprouts, or a concentrated extract, as an ordinary human serving. This is how a pharmacology result becomes dinner advice. ## Digestive tolerance, which is a different question Worth separating out, because it is the one a reader might actually be asking. **Do microgreens upset people?** There is no published study on that either, and no case report attributing digestive harm to eating them as a food. The National Institute of Diabetes and Digestive and Kidney Diseases lists cruciferous vegetables, including broccoli, cauliflower, collard greens and kale, among the foods whose carbohydrates can lead to excess gas. That is about the grown vegetables; it has not been measured for the seedlings, and a 16 g serving is far smaller than a portion of either. For digestive symptoms generally, the American Gastroenterological Association's guidance on irritable bowel syndrome says that [soluble fiber is effective for global IBS symptoms](https://gastro.org/clinical-guidance/the-role-of-diet-in-irritable-bowel-syndrome-ibs/) and that the [low-FODMAP diet](https://microgreensguru.com/blog/are-microgreens-low-fodmap/) is the most evidence-based dietary intervention available. It does not mention microgreens, and that guidance is condition-specific rather than something to convert into a crop recommendation. ## Safety, which is a separate subject and a real one **Warfarin.** Leafy greens carry vitamin K, which [interacts seriously with warfarin](https://ods.od.nih.gov/factsheets/vitaminK-Consumer/), and a sudden change in how much you eat is the thing that causes problems. Consistency is the advice. **Thyroid, oxalate and nitrate.** Brassica glucosinolates have a plausible effect on iodine uptake, but a systematic review found the human evidence limited and inconsistent about what material was even tested. Oxalate is a documented concern in mature spinach, beet and chard for people with calcium-oxalate stones, and no microgreen threshold exists. Nitrate concerns are documented mainly for very young infants and for contaminated water or poor storage. **Raw produce.** These are eaten raw. There has been [an FDA recall](https://www.fda.gov/safety/recalls-market-withdrawals-safety-alerts/greenbelt-greenhouse-ltd-recalls-greenbelt-microgreens-brand-microgreens-because-possible-health) of microgreens for possible listeria, with no illnesses reported, and a [retail survey](https://pubmed.ncbi.nlm.nih.gov/31895586/) has detected pathogenic and potentially pathogenic bacteria in microgreens, sprouts and sprouted seeds. That is a hazard signal rather than documented harm, and it matters most in pregnancy, immunocompromise and frailty. Microgreens are not sprouts, whose record is much worse: FDA counted [52 outbreaks and more than 2,700 illnesses from 1996 to 2020](https://www.fda.gov/food/hfp-constituent-updates/fda-issues-final-guidance-seeds-used-sprouting). Warm, wet, nutrient-rich sprouting conditions are what let a pathogen on a seed multiply. **Not every microgreen is the same.** Borage is the live exception, with pyrrolizidine alkaloids measured far above the EU limit, as the [borage page](https://microgreensguru.com/microgreen-types/borage/) sets out. "Microgreens" is a category, not an ingredient. ## So, do microgreens help your gut **Unknown, because it has not been tested.** Eating them adds some fiber and plant compounds, and the eleven-person study shows the compounds get absorbed and that gut bacteria are part of how they are processed. Whether that changes your bacteria in any way you would notice, or how you feel, has not been tested. On the fiber route specifically, the arithmetic says a normal serving is too small to be doing the work people credit it with. What is solid: these are plant foods with real, crop-specific nutrients, and broccoli, kale, mustard and radish microgreens all carry measurable amounts of the compounds people are interested in. If you want the crop the one human study actually used, that is [broccoli](https://microgreensguru.com/go/seed-broccoli/), and it is also the cheapest and fastest thing to start with. If you want the ones that measured highest for isothiocyanates, that is [mustard](https://microgreensguru.com/go/seed-mustard/) and [radish](https://microgreensguru.com/go/seed-radish/). If you have a diagnosed digestive condition, take that to your doctor rather than to a microbiome claim on a website, including this one. ## What would settle it A randomized, controlled, assessor-blinded trial in adults with functional constipation or IBS-like symptoms, comparing a batch-assayed fresh broccoli microgreen against a matched low-glucosinolate leafy control. Measure total diet and what the microgreens displaced, symptoms and validated stool outcomes, stool sequencing plus short-chain fatty acids, and sulforaphane metabolites in blood and urine, over at least 8 to 12 weeks with follow-up. The eleven-person study already did the hard part, which is showing the compounds get in. Nobody has done the part that would tell you whether it matters. ### Terms on this page **Microbiome.** The community of bacteria and other organisms living in your gut. Usually measured from a stool sample by sequencing the DNA in it. **Alpha diversity.** How many different types of organism live in one person's gut, and how evenly. This is the number behind the phrase "a diverse microbiome", and it is worth knowing that fiber trials have struggled to move it. **SCFAs.** Short-chain fatty acids. What gut bacteria produce when they ferment fiber, and the main reason fiber is thought to matter. Butyrate is the one that gets the most attention. **Bifidobacterium.** A bacterial group widely treated as beneficial and used as the headline outcome in prebiotic research. **Fermentable fiber.** Plant material your small intestine cannot digest, which arrives in the colon intact for the bacteria to work on. **Glucoraphanin.** The storage compound in broccoli and its relatives. Inactive until the plant tissue is damaged. **Sulforaphane.** What glucoraphanin becomes. The active compound behind every claim on this subject. **Myrosinase.** The plant's own enzyme that performs the conversion when you chew or chop. Certain gut bacteria can do a version of the same job further down. **Bioaccessibility.** The fraction of a compound released from the food and available for absorption, as measured in a laboratory model of digestion. Not the same as how much actually gets into you. **DSS colitis.** A standard laboratory method of inducing gut inflammation in mice by adding a chemical to their drinking water. A disease model, not a person. **SMD.** Standardized mean difference. A way of pooling studies that measured the same idea in different units. Read against zero. **Open-label.** Everyone knows what they are getting. It matters most when the outcome is a symptom the participant scores themselves. ## Sources - [2023 fresh broccoli microgreen human study](https://pubmed.ncbi.nlm.nih.gov/37893677/), with [methods and composition](https://pmc.ncbi.nlm.nih.gov/articles/PMC10606698/) - 11 healthy people, a single 16 g serving of 10-day microgreens; glucoraphanin 12.8 micromol/g at day 1 and 13.6 at day 6, sulforaphane 7.2 and 6.4; metabolites in urine and stool, no symptom or efficacy endpoint, and pregnancy plus significant GI disease excluded. - [Yanaka, 2018](https://pubmed.ncbi.nlm.nih.gov/29371757/) - 48 adults with constipation, 20 g/day raw broccoli or alfalfa sprouts for four weeks; constipation score 7.25 to 5.17 (p = 0.0017), defecation-attempt score 0.96 to 0.58 (p = 0.0077), Bifidobacterium percentage down (p = 0.0498), semi open-label, and the declared farm funding and endowed chair. - [Atwell et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25522265/) - 10 people, fresh sprouts against myrosinase-treated extract at 200 micromoles sulforaphane equivalents; about threefold higher metabolites from the fresh plant. - [Egner et al., 2011](https://pubmed.ncbi.nlm.nih.gov/21372038/) - 50 people, sprout beverages at 800 micromoles glucoraphanin or 150 micromoles preformed sulforaphane, seven days each; urinary metabolite recovery only. - [Clarke et al., 2011](https://pubmed.ncbi.nlm.nih.gov/21816223/) - 12 people, 40 g fresh sprouts against six supplement pills; lower and delayed exposure from the supplement. - [So et al., 2018, fiber meta-analysis](https://kclpure.kcl.ac.uk/ws/files/88429815/Dietary_fiber_intervention_on_SO_Published2018_GREEN_AAM.pdf) - 64 randomized trials, 2,099 people; Bifidobacterium SMD 0.64 (0.42 to 0.86), Lactobacillus 0.22 (0.03 to 0.41), fecal butyrate 0.24 (0.00 to 0.47), and no difference in alpha diversity. - [Brassica microgreen composition review](https://pubs.acs.org/doi/10.1021/acsfoodscitech.3c00040) - fresh-weight fiber of broccoli 0.36, mustard 2.08 and radish 1.78 g/100 g.
