As consumers continue to demand more from the beverages they buy, the Ready-to-Drink (RTD) category has quickly become a playground for functional innovation. Energy-boosting, cognition-enhancing, gut-friendly — if it offers a benefit, there’s a brand trying to bottle it.
One functional ingredient gaining serious momentum in RTDs is creatine. Once confined to gym bags and powdered tubs, creatine is stepping into the mainstream as a daily-use ingredient for cognitive performance, strength, energy, and overall wellness. But working creatine into RTD beverages isn’t as simple as adding a scoop and screwing on a cap.
Below, we break down why creatine is rising in the RTD world, the challenges beverage formulators must overcome, and how Siena is uniquely positioned to help brands bring creatine-powered beverages to market faster and with fewer headaches.
Creatine has one of the strongest safety and efficacy profiles in the supplement world. Its benefits are well-documented:
Improved strength and power output
Enhanced energy availability (via ATP regeneration)
Cognitive support, especially under stress or sleep deprivation
Potential mood and neuroprotective effects
Increasing appeal as a general-health ingredient
The mainstream shift is happening fast — daily creatine intake is no longer reserved for athletes, and consumers want convenient, ready-to-drink formats that fit their busy routines. RTDs provide exactly that: habitual, simple, and enjoyable delivery without the hassle of powders.
Despite its massive potential, creatine introduces real formulation and operational hurdles in beverages:
Creatine monohydrate can degrade into creatinine in water over time, especially under higher temperatures or acidic pH — a major concern for shelf-stable or ambient RTDs.
Creatine adds a slight bitterness and chalkiness that can be hard to mask without introducing overpowering flavors.
Some forms of creatine don’t fully dissolve, which can lead to sedimentation or cloudiness — unacceptable in most premium RTD formats.
Different creatine forms have different regulatory statuses depending on region. Claims also need to be carefully substantiated.
Creatine may interact with other functional ingredients, sweeteners, or preservatives. Co-packing partners may also be unfamiliar or uncomfortable working with it.
Successfully launching a creatine RTD requires navigating all of these considerations without compromising taste, stability, or brand experience.
This is exactly where Siena becomes a transformative partner. Siena is designed to streamline the entire product development lifecycle — from early formulation choices to manufacturer matching — ensuring your creatine RTD is not just feasible, but exceptional.
Siena helps teams understand:
Which creatine forms (monohydrate, HCl, nitrate, citrate, etc.) best match stability and mouthfeel goals
How creatine interacts with acidity, sweeteners, electrolytes, caffeine, and other actives
Potential formulation pitfalls before they cost time and money
This reduces reliance on guesswork and shortens R&D cycles dramatically.
Siena’s system flags risks related to:
Solubility
pH stability
Heat processing impact
Shelf-life concerns
Serving-size limits and compliance
This ensures the formulation you’re designing is actually manufacturable.
Not every co-packer knows how to handle creatine. Siena connects your team with manufacturers who:
Have experience producing creatine-based beverages
Support the right processing methods
Allow pilot runs for functional ingredients
Fit your packaging format and minimum order quantities
This eliminates the months that brands often waste emailing generic contract manufacturers who aren’t suitable for creatine projects.
By centralizing formulation guidance, operational requirements, documentation, and manufacturer matching, Siena helps teams:
Cut development time
Avoid expensive reformulations
Produce more stable, better-tasting products
Launch high-performing RTDs that consumers love
Creatine beverages are an exciting frontier — and Siena helps brands enter that market with clarity, confidence, and speed.
Creatine is poised to become one of the most in-demand RTD functional ingredients thanks to its wide appeal and robust benefits. But its chemistry and stability challenges require thoughtful formulation and capable manufacturing partners.
With Siena, beverage brands can navigate those challenges seamlessly, leveraging expert-level insights and a purpose-built platform to bring innovative creatine RTDs to shelf faster and more effectively.
If you’re ready to build a creatine-enhanced beverage—or improve one you already have—Siena can help you make it happen.
