Vitamin water, magnesium-infused beer, drinks high in fiber—the market for functional beverages is booming. But what truly lies behind the promise of improving your health with every sip? Falstaff spoke to producers and a nutrition expert to find out.
Functional drinks are the new superfood. Magnesium-enriched alcohol-free beer, vitamin water, drinks rich in fiber, recovery shots after workouts—they promise more energy, sharper focus, radiant skin and a happier microbiome. Designed to fit seamlessly into a “conscious” lifestyle, they suggest that better health can be just a sip away. But are the benefits real—or is it just smart marketing at work?
Much of the skepticism centers on how much vitamin these beverages truly provide. Many products cover only a small fraction of the recommended daily intake per bottle. The team behind Focus Water stresses that a balanced diet and regular exercise remain fundamental, describing their drink as a convenient supplement rather than a substitute. Designed for consumers who want flavor and functionality in one, the Swedish brand has offered lightly sweetened, low-calorie drinks fortified with vitamins and minerals since 2008—positioned as an alternative to sugary soft drinks and juices.
If you eat a balanced diet, you generally do not need additional synthetic vitamins in your daily routine.
A newer wave of functional beverages shifts the focus away from vitamins and toward fiber, probiotics, and complex ingredient mixtures. The fibre drink Super Pop, co-developed by German influencer and investor Pamela Reif, contains around six grams of fiber per can, combined with apple cider vinegar, probiotic cultures, and a sugar-free formula. Marketed to support a healthy gut, it aims to deliver a “good gut feeling.”
The trend has also reached the beer market. Calanda recently introduced Vita 0.0, a non-alcoholic lager enriched with magnesium and vitamin B6, explicitly promoted as suitable even during working hours. According to Brand Manager Sarina Hasler, the product reflects evolving drinking habits and a growing demand for alcohol-free options. The added nutrients are carefully selected: magnesium and vitamin B6 support energy metabolism and the nervous system, making them particularly beneficial after exertion or a challenging day. Yet even without alcohol—and with moderate functional additions—beer remains primarily an emotional and social beverage.
Dr. Melanie Loessner, a nutritionist based in Zurich, urges moderation in expectations: “Many people overestimate the benefits of such products.” For individuals with a balanced diet, additional vitamins typically offer little added value. Excess water-soluble vitamins such as B vitamins or vitamin C are simply excreted by the body.
She also highlights potential downsides. Many functional drinks contain sugar or fruit juice concentrates, placing them nutritionally closer to soft drinks than their health-focused image suggests. They provide energy without satiety. Even sugar-free, flavored options are often highly acidic, increasing the risk of dental erosion when consumed frequently.
There is, however, some potential in fiber-enriched drinks. Soluble fibers such as inulin or dextrin can act as prebiotics, nourishing beneficial gut bacteria. Six grams per serving can make a meaningful contribution toward the recommended daily intake of at least 30 grams—provided the overall diet supports it.
In the end, functional drinks may complement a healthy lifestyle—but they are no shortcut to it.
Why do we keep reaching for drinks that promise focus, balance, or a glowing complexion—even when we suspect it’s mostly marketing? Nutritionist Loessner points to the so-called halo effect: “Humans love simple solutions.” A flavorful beverage that eases the guilt of an imperfect diet is naturally tempting. When a single health claim casts a positive light on the product, pleasure and perceived health benefits merge, guilt diminishes, and the likelihood to purchase the beverage rises.
A closer look shows that functional drinks are not so much a medical breakthrough, but rather a reflection of our times. A healthy lifestyle is expected to be simple, convenient, and enjoyable—ideally in a portable, on-the-go format. The question isn’t whether functional drinks are inherently “good” or “bad.” What matters more is how we consume them: as a flavorful alternative to soft drinks, an occasional supplement, or a convenient substitute that can distract us from our actual dietary needs.
