The Power of Belief: Placebo vs. Performance in Functional Beverages

Functional drinks are fast becoming the new fizzy drinks! A century ago, carbonation and catchy labels made for a popular beverage. Today, consumers are looking for drinks that do more than just refresh—they want benefits in every sip. From boosting energy and improving focus to enhancing relaxation or aiding recovery, functional beverages are taking centre stage. Just two years ago, only a handful of clients at No Name Drinks Development were interested in functional drinks; today, almost half of our new inquiries are in the functional space.

But here’s a fascinating question: Does it really matter if these drinks work scientifically or if they just make us feel like they do? Surprisingly, in many cases, the line between genuine effect and placebo effect is blurred—and for consumers, that distinction may not matter at all.

The Placebo Effect in Functional Beverages

The placebo effect is often misunderstood; it’s not just about “tricking” the mind but is about the brain’s power to generate real physical and psychological responses. In functional beverages, simply believing a drink is providing energy or reducing stress can make a person feel these effects, even if the ingredients themselves aren’t particularly potent.

Consider a study from 2010 where participants believed they were consuming an energy drink. Although it was a placebo, they reported feeling more alert and performed better in cognitive tasks. The real catalyst? Expectation. This example shows the power of branding, taste, and messaging in shaping the consumer experience, even when the science behind the benefits isn’t fully supported.

Do Functional Drinks Really Work?

Of course, not all functional drinks rely on placebo. Many contain active ingredients backed by research that show genuine physical and cognitive benefits. Adaptogens like ashwagandha or nootropics like L-theanine have shown promise in reducing stress and enhancing mental clarity. Electrolytes and amino acids in sports drinks aid hydration and muscle recovery.

Driven by rising consumer demand for wellness-supporting beverages, the functional beverage market is expected to reach an impressive $208 billion by 2030, according to a 2023 report by Grand View Research. This growth indicates that consumers aren’t just buying into the idea of functionality—they’re experiencing benefits firsthand through ingredients like vitamins, herbal extracts, or probiotics designed to support wellness.

The Blurred Line: Placebo vs. Performance

Still, the line between perception and performance remains. Imagine drinking a bottle of “focus-enhancing” water before an important meeting. Thanks to its sleek design, targeted marketing, and maybe even a suggestive flavour profile, you feel sharper and more confident. Whether the active ingredients are the real hero or your brain is doing the heavy lifting, the result is the same: improved performance.

For instance, in one experiment, participants who thought they were drinking a high-caffeine energy drink showed increased physical activity—even though the drink contained no caffeine at all. This example reveals that belief in a product’s effectiveness can drive real changes in mood, behaviour, and energy.

Functionality Meets Expectation

For brands in the functional beverage space, the key takeaway is that actual and perceived benefits both matter. Consumers seek functional drinks to give them an edge, whether it’s more energy, sharper focus, or a calm, clear mind. But the impact goes beyond ingredients; how those ingredients are marketed, presented, and understood also influences the experience.

Functional drinks may be powered by science, placebo, or a bit of both. What’s clear is that they are fulfilling a deep-seated consumer desire for performance in a can or bottle. As functional beverages continue to replace traditional fizzy drinks, they’re reshaping the beverage industry, blending science, psychology, and sensory experience into every sip.

Final Thoughts: The Future of Functional Beverages

Whether it’s the power of ingredients or the power of belief that drives functional beverage success, one thing is certain: these drinks are here to stay. Claims about functionality must be well-defined on the label, and we guide clients through regulatory considerations when developing new products.

For many, the placebo effect is just part of the package—contributing to the overall experience, often without consumers even realising it.

We have exciting projects lined up in the functional drinks space for 2025, so stay tuned!
