The Best Ingredients for RTM and RTD Applications

Convenience continues to drive the functional beverage category. Consumers want products that fit into their busy routines. Grab-and-go or ready-to-mix (RTD) options are easy on-the-go choices for the gym, work, or while traveling.

Developing a successful RTM or RTD product requires careful consideration when it comes to solubility, flavor, mouthfeel, stability, sweetness, acidity, and the overall consumer experience. It should also deliver the functional benefits consumers expect from a product.

Minerals and Electrolytes

We all know that hydration is about more than water. Minerals and electrolytes are central to many hydration formulations because they can support fluid balance and give brands the opportunity to create products for active nutrition, sports nutrition, healthy aging, and general wellness. Many ingredients can be considered in this category, with popular ones being:

Sodium Citrate – A versatile source of sodium that can contribute to an electrolyte system while helping manage acidity and flavor balance. Commonly used in hydration powders and beverages.

Potassium Chloride – A widely used source of potassium for electrolyte and hydration formulations. It can help strengthen the mineral profile of RTM and RTD products.

Magnesium Citrate – A popular magnesium source for functional beverages and powdered drink mixes. Magnesium citrate is compatible with many hydration ingredients.

Magnesium Lactate – A highly soluble magnesium source that is well suited for beverage products where dispersibility and clean label formulation are key.

Magnesium Bisglycinate – A chelated form of magnesium selected for premium wellness and mineral formulations.

Calcium Citrate – A calcium source that can add essential minerals to multifunctional hydration and wellness beverages. Calcium citrate is interesting for formulators looking to move beyond basic sodium-and-potassium electrolyte systems.

Himalayan Salt Powder – Provides sodium and chloride and is a naturally occurring salt source for hydration. It can be incorporated into premium sports nutrition product concepts.

Choosing a mineral depends on the intended product format, serving size, and flavor profile. Taste matters when working with electrolytes, and some mineral sources can contribute salty, bitter, or metallic flavors.

Coconut

Coconut has become well known for its hydration benefits, making it an appealing ingredient for active lifestyle products. Coconut-based ingredients can support natural-inspired positioning and complement tropical, citrus, and fruit-flavored products. They can be seamlessly incorporated into RTM hydration stick packs, powdered electrolyte blends, and wellness drink mixes. Evaporated coconut water powder and coconut crystals are two ingredient offerings that are easy to formulate into functional food and beverage products. 

Acidulants

Acidulants are ingredients used to add or control acidity in a beverage formulation. They help create tartness and brightness, balance sweetness, and shape the flavor profile. In RTM and RTD applications, acidulants can help manage the taste of minerals, caffeine, and other functional ingredients. The right acidulant can help make a formula more complete, especially when it includes ingredients that introduce bitter, salty, or metallic notes. 

Citric Acid Anhydrous – a widely used acidulant that delivers clean, bright tartness and performs well in citrus and fruit-flavored beverages.

L-Malic Acid –provides a smooth, lingering tartness that complements flavors such as apple, berry, watermelon, and other fruit profiles.

Natural L-Tartaric Acid –provides a sharp acidity that can help create a crisp, refreshing taste.

Energy in Beverages

Hydration and energy are an increasing interest for consumers looking for convenient products that do more than provide fluids and electrolytes. Hydration products provide a natural platform for incorporating ingredients that support alertness, focus, attention, and an active lifestyle.

Natural Caffeine - a versatile option for formulators that adds energy to powders, stick packs, and functional beverages. Caffeine is well established and well-studied in the energy category and can support alertness and reduce feelings of fatigue.

Green Tea Caffeine – provides caffeine with the added appeal of a plant-derived source. Green tea caffeine can complement hydration formulations in the active living categories.

Green Tea Extract - EGCG – this combination lets formulators build a broader functional and benefit story around their product. EGCG, or epigallocatechin gallate, is one of the primary catechins naturally found in green tea. Green tea extracts containing EGCG create opportunities to pair hydration with additional botanical functionality.

Specialty Ingredients Driving Hydration

Hydration products are being formulated as multifunctional wellness products, and specialty ingredients give brands more room to highlight benefits on their packaging.

Creatine Monohydrate – can connect hydration and sports nutrition in products targeting athletes and physically active consumers.

Organic Aloe Vera Powder – provides a botanical ingredient that can complement hydration and wellness.

Fiber ingredients offer opportunities for broader functional positioning. Inulin powder, liquid inulin, and resistant dextrin give formulators options for incorporating fiber into products that require more than hydration alone.

There is no single formula for hydration – a sports nutrition product may prioritize sodium, potassium, magnesium, energy, and performance ingredients, while an everyday beverage may emphasize minerals, coconut-derived ingredients, fiber, and a lower-sugar sweetener system. This flexibility creates an opportunity for brands to develop hydration products tailored to specific consumer needs.

From electrolytes and coconut-based ingredients to energy, specialty ingredients, and sweeteners, Barrington Nutritionals offers a broad portfolio of ingredients to help brands develop differentiated functional beverage concepts.
