Tequila is not good for you in any meaningful health sense. It is an alcoholic beverage, and alcohol is classified as a carcinogen by the International Agency for Research on Cancer. That said, tequila has earned a reputation as the “healthiest” spirit, and there’s a sliver of real science behind the hype. The key is understanding what that science actually shows and where the popular claims fall apart.
Where the Health Claims Come From
Almost every positive health claim about tequila traces back to research on agavins, a type of fructan (a chain of fructose molecules) found in the agave plant. Agavins are genuinely interesting compounds. In one widely cited study, obese mice with type 2 diabetes that received agavins in their water ate less food, lost weight, and had lower blood sugar compared to mice given other sugars or even artificial sweeteners. The agavins also boosted insulin production and raised levels of a gut hormone called GLP-1, which slows digestion and increases feelings of fullness.
Agave fructans have also shown promise for bone health. In a study using mice that had their ovaries removed (a model for postmenopausal bone loss), a diet supplemented with 10% agave fructans increased calcium levels in both blood and bone tissue. Osteocalcin, a protein involved in building new bone, rose by more than 50%. Trabecular bone loss, the spongy interior structure that weakens in osteoporosis, also slowed.
These are real findings from real research. The problem is that none of them are about tequila.
Why Tequila Isn’t the Same as Agavins
Tequila is made by cooking agave hearts, fermenting the sugars, then distilling the liquid twice at high heat. Distillation separates and concentrates alcohol from the fermented liquid. The agavins, which are complex sugar chains, get broken down during cooking and fermentation. What survives doesn’t make it through two rounds of distillation. By the time agave juice becomes tequila, the fructans that produced those impressive mouse studies are gone.
The same logic applies to the probiotic claim that occasionally circulates online. Fermentation does involve beneficial microorganisms, but distillation involves extreme heat. No living bacteria survive the process. Tequila is not a probiotic.
What Agave Fructans Actually Do in Your Gut
Unprocessed agave fructans, eaten as food or supplements rather than distilled into spirits, do have legitimate prebiotic effects. Research in mice fed a high-fat diet found that agavins shifted gut bacteria composition in favorable directions, increasing populations of beneficial species like Bacteroides, Akkermansia, and Faecalibaculum while decreasing less desirable ones. These shifts came with a significant increase in butyrate, a short-chain fatty acid that helps maintain the intestinal lining and reduces inflammation.
In another comparison study, agave syrup that retained most of its fructans (about 55% fructan content) led to 35% less weight gain, 18 to 22% lower triglycerides, and dramatically reduced oxidative stress compared to highly processed agave syrup that was mostly free fructose. Once the fructans were broken down into simple fructose, the syrup behaved much like high-fructose corn syrup, promoting insulin resistance and fat accumulation in the liver.
The takeaway: agave fructans are beneficial. Agave-derived alcohol is not the same thing.
How Tequila Compares to Other Spirits
Tequila does have a few minor advantages over some other liquors, though none of them qualify as “health benefits.” A standard shot of tequila contains roughly 97 calories with zero carbohydrates, zero sugar, and zero fat. That’s comparable to vodka or whiskey and lower than sugary cocktails, sweet wines, or beer. If you’re choosing a drink and counting calories, straight tequila is a relatively lean option.
Quality matters here more than with most spirits. Tequila labeled “100% agave” contains only distilled agave sugars. Mixto tequila, which only needs to be 51% agave, can include a range of additives: colorings, flavorings, and other non-agave ingredients. Producers of mixto tequila are not required to disclose what additives they use, so you won’t know what’s in the bottle. If you drink tequila, choosing 100% agave at least eliminates those unknowns.
The Alcohol Problem You Can’t Get Around
No matter how pure the tequila, it still contains ethanol, and ethanol is the component that causes harm. The World Health Organization states plainly that health risks increase in a dose-dependent manner: the more you drink and the more often you drink, the greater the danger. Risks rise exponentially with the amount consumed in a single sitting, which is particularly relevant to tequila given how often it’s consumed as shots.
The WHO also notes that defining a universally safe level of alcohol consumption is essentially impossible, because any amount carries some degree of short-term and long-term risk. Alcohol is linked to several types of cancer, liver disease, cardiovascular problems, and mental health effects. These risks apply equally whether the alcohol comes from tequila, wine, beer, or any other source.
The Bottom Line on Tequila and Health
The pattern behind most tequila health claims follows a predictable formula: researchers study a compound found in the agave plant, that compound shows benefits in animal studies, and then headlines attribute those benefits to the finished spirit. But the distillation process strips out the very compounds that made the research promising. Drinking tequila does not deliver agavins, prebiotics, or bone-building fructans to your body. It delivers ethanol, water, and trace flavor compounds.
If you enjoy tequila in moderation, choosing 100% agave and drinking it straight (rather than in sugary margaritas) is the least harmful way to go about it. But framing any alcoholic drink as “good for you” requires ignoring what the science consistently shows about alcohol itself.
