A woman suffers from a debilitating headache during a hangover.
Probiotics seem to be everywhere these days. They are marketed for numerous health issues, from irritable bowel syndrome and vaginal yeast infections to life-threatening disorders like the bacterial infection Clostridium difficile.
The new probiotic drink is made of genetically engineered bacteria meant to help people feel better the day after drinking.
While the probiotic gummies that you'll find in supermarkets may not do much for you, good clinical evidence does support the C. difficile treatment, known as a fecal transplant, despite a recent setback, and there are always new probiotic regimens entering the scene. One emerging such treatment targets the hangover.
The Lowdown
You read that right – although "hangover" is a loaded term, according to ZBiotics, the company that's developing the product. The popular understanding of a hangover implies a collection of symptoms like a headache and fatigue, many of which result simply from dehydration and low-quality sleep. But those aren't the problems that the new product, a genetically engineered form of a common bacterial species, was developed to confront.
"Dehydration and poor sleep have actually always been pretty simple to deal with by having a good breakfast and some caffeine," notes ZBiotics founder and microbiologist Zack Abbott. Instead, the product targets acetaldehyde, a chemical that accumulates in the body if more than small amounts of alcohol are consumed.
Normally, body cells produce an enzyme that converts acetaldehyde into harmless acetic acid. But the enzyme becomes overwhelmed if you drink more than a little alcohol, or if you have a certain genetic deficiency.
A new probiotic drink aims to neutralize a chemical that builds up in the body after drinking alcohol.

"I started ZBiotics with the hypothesis that if we used edible probiotic bacteria to make enzymes, and chose applications in which the enzymes these microbes make would be useful directly in the gut after you eat them, we could create all sorts of beneficial products," says Abbott. "I started with alcohol with the idea that we can augment the body's natural ability to digest its nasty byproduct, acetaldehyde, helping people feel better the day after drinking."
Next Steps
Based on the premise that the engineered bacteria augments a natural body function, ZBiotics had the product "sampled by thousands of beta-testers," including ZBiotics personnel, with "almost unanimously positive feedback," says Abbott.
"We are working on future scientifically controlled testing for publication."
ZBiotics is to set to launch on the market next week as a probiotic supplement, a category that does not require FDA approval. But some observers are troubled over whether the new product is attempting to serve a medical function without going through the standard drug testing process.
"I am skeptical of any new alternative product that is not FDA approved, has not undergone rigorous double-blind placebo control testing and adverse effects evaluation, and cites anecdotes as evidence of its efficacy," warns Heather Berlin, a cognitive neuroscientist and assistant professor of psychiatry at Icahn School of Medicine at Mount Sinai, in New York.
Abbott acknowledges that his product still needs to undergo rigorous study. "We are working on future scientifically controlled testing for publication," he says, noting that the company was "founded and [is] run by people with backgrounds in academic research."
Open Questions
Moving beyond the need for proper testing, Berlin has an additional concern: will a "hangover"-blocking substance cause people to drink more alcohol, or mask important physiological sensations like thirst?
"If that negative feeling is obscured, they may not [rehydrate], which can cause numerous adverse effects," Berlin says.
As for excessive drinking, there is a treatment on the market that does the opposite of Zbiotics. Disulfiram, commonly given to alcohol abusers, inhibits the very enzyme that ZBiotics supplements, causing acetaldehyde to accumulate especially fast. This makes drinking a pretty miserable experience.
But Abbott says his product would not interfere with disulfiram.
"[Zbiotics] is about enjoying the special moments in life where alcohol happens to be involved, but isn't the main focus."
"Disulfiram globally inhibits the enzyme throughout the entire body, including the liver, creating a massive amount of acetaldehyde at once, making the person ill immediately and forcing them to stop drinking right away," Abbott explains, whereas his product exerts its effects in the gut, and is really only helpful the next day. Thus, timing is everything; the probiotic would not change the experience at the moment of drinking.
"ZBiotics isn't about going out and ripping shots all night," Abbott says. "It's about enjoying the special moments in life where alcohol happens to be involved, but isn't the main focus. Weddings, celebrations, weekends with friends. And wanting to do that enjoyably while being safe and responsible at the same time."
Sharing land and other resources among farmers isn’t new. But research shows it may be increasingly relevant in a time of climatic upheaval.
Sharing land and other resources among farmers isn’t new. But research shows it may be increasingly relevant in a time of climatic upheaval, potentially influencing “farmers to adopt environmentally friendly practices and agricultural innovation,” according to a 2021 paper in the Journal of Economic Surveys. Farmers might share knowledge about reducing pesticide use, says Heather Frambach, a supply chain consultant who works with farmers in California and elsewhere. As a group they may better qualify for grants to monitor soil and water quality.
Most research around such practices applies to cooperatives, whose owner-members equally share governance and profits. But a collective like Carman Ranch’s — spearheaded by fourth-generation rancher Cory Carman, who purchases beef from eight other ranchers to sell under one “regeneratively” certified brand — shows when producers band together, they can achieve eco-benefits that would be elusive if they worked alone.
Vitamins and minerals in soil pass into plants through their roots, then into cattle as they graze, then back around as the cows walk around pooping.
Carman knows from experience. Taking over her family's land in 2003, she started selling grass-fed beef “because I really wanted to figure out how to not participate in the feedlot world, to have a healthier product. I didn't know how we were going to survive,” she says. Part of her land sits on a degraded portion of Zumwalt Prairie replete with invasive grasses; working to restore it, she thought, “What good does it do to kill myself trying to make this ranch more functional? If you want to make a difference, change has to be more than single entrepreneurs on single pieces of land. It has to happen at a community level.” The seeds of her collective were sown.
Raising 100 percent grass-fed beef requires land that’s got something for cows to graze in every season — which most collective members can’t access individually. So, they move cattle around their various parcels. It’s practical, but it also restores nutrient flows “to the way they used to move, from lowlands and canyons during the winter to higher-up places as the weather gets hot,” Carman says. Meaning, vitamins and minerals in soil pass into plants through their roots, then into cattle as they graze, then back around as the cows walk around pooping.

Each collective member has individual ecological goals: Carman brought in pigs to root out invasive grasses and help natives flourish. Probert also heads a more conventional grain-finished beef collective with 100 members, and their combined 6.5 million ranchland acres were eligible for a grant supporting climate-friendly practices, which compels them to improve soil and water health and biodiversity and make their product “as environmentally friendly as possible,” Probert says. The Washington veg farmer reduced tilling and pesticide use thanks to the ecoservices of visiting cows. Similarly, a conventional hay farmer near Carman has reduced his reliance on fertilizer by letting cattle graze the cover crops he plants on 80 acres.
Additionally, the collective must meet the regenerative standards promised on their label — another way in which they work together to achieve ecological goals. Says David LeZaks, formerly a senior fellow at finance-focused ecology nonprofit Croatan Institute, it’s hard for individual farmers to access monetary assistance. “But it's easier to get financing flowing when you increase the scale with cooperatives or collectives,” he says. “This supports producers in ways that can lead to better outcomes on the landscape.”
New, smaller scale farmers might gain the most from collective and cooperative models.
For example, it can help them minimize waste by using more of an animal, something our frugal ancestors excelled at. Small-scale beef producers normally throw out hides; Thousand Hills’ 50 regenerative beef producers together have enough to sell to Timberland to make carbon-neutral leather. In another example, working collectively resulted in the support of more diverse farms: Meadowlark Community Mill in Wisconsin went from working with one wheat grower, to sourcing from several organic wheat growers marketing flour under one premium brand.
Another example shows how these collaborations can foster greater equity, among other benefits: The Federation of Southern Cooperatives has a mission to support Black farmers as they build community health. It owns several hundred forest acres in Alabama, where it teaches members to steward their own forest land and use it to grow food — one member coop raises goats to graze forest debris and produce milk. Adding the combined acres of member forest land to the Federation’s, the group qualified for a federal conservation grant that will keep this resource available for food production, and community environmental and mental health benefits. “That's the value-add of the collective land-owner structure,” says Dãnia Davy, director of land retention and advocacy.
New, smaller scale farmers might gain the most from collective and cooperative models, says Jordan Treakle, national program coordinator of the National Family Farm Coalition (NFFC). Many of them enter farming specifically to raise healthy food in healthy ways — with organic production, or livestock for soil fertility. With land, equipment and labor prohibitively expensive, farming collectively allows shared costs and risk that buy farmers the time necessary to “build soil fertility and become competitive” in the marketplace, Treakle says. Just keeping them in business is an eco-win; when small farms fail, they tend to get sold for development or absorbed into less-diversified operations, so the effects of their success can “reverberate through the entire local economy.”
Frambach, the supply chain consultant, has been experimenting with what she calls “collaborative crop planning,” where she helps farmers strategize what they’ll plant as a group. “A lot of them grow based on what they hear their neighbor is going to do, and that causes really poor outcomes,” she says. “Nobody replanted cauliflower after the [atmospheric rivers in California] this year and now there's a huge shortage of cauliflower.” A group plan can avoid the under-planting that causes farmers to lose out on revenue.
It helps avoid overplanted crops, too, which small farmers might have to plow under or compost. Larger farmers, conversely, can sell surplus produce into the upcycling market — to Matriark Foods, for example, which turns it into value-add products like pasta sauce for companies like Sysco that supply institutional kitchens at colleges and hospitals. Frambach and Anna Hammond, Matriark’s CEO, want to collectivize smaller farmers so that they can sell to the likes of Matriark and “not lose an incredible amount of income,” Hammond says.
Ultimately, farming is fraught with challenges and even collectivizing doesn’t guarantee that farms will stay in business. But with agriculture accounting for almost 30 percent of greenhouse gas emissions globally, there's an “urgent” need to shift farming practices to more environmentally sustainable models, as well as a “demand in the marketplace for it,” says NFFC’s Treakle. “The growth of cooperative and collective farming can be a huge, huge boon for the ecological integrity of the system.”
