If you’ve ever poured a powder into a shaker, added water or milk, and ended up with a smooth, consistent drink—whether it’s a post-workout protein shake, a sugar-free iced tea mix, or a plant-based meal replacement—you’ve interacted with a solid drink made through OEM or ODM. As someone who’s spent the last 12 years running a solid drink OEM/ODM facility, I hear this question all the time from new clients: What actually goes into these powders? It’s easy to assume they’re just “powdered versions of regular drinks,” but the reality is far more intentional. Every ingredient we choose is tested for solubility, shelf stability, flavor, and functionality—because when a brand sends us a formula or comes to us with a concept, we don’t just mix powders; we build a product their consumers can rely on. Solid Drink OEM/ODM
Let’s break down the core categories of ingredients we use every day, tailored specifically for solid drinks, not liquid or baked goods. These are the workhorses of our production line, and I’ll explain why each matters, from the most common staples to the less obvious functional ingredients that make or break a product.
First, the base ingredients—this is the largest part of almost every solid drink powder, and it’s what gives the bulk, texture, and foundational nutrition. The most ubiquitous base is maltodextrin, and I swear by it for 90% of our clients, from small brands launching a new fiber drink to larger names expanding their protein line. What is maltodextrin, exactly? It’s a polysaccharide made from starch (usually corn, rice, or potato) that’s broken down into small, easily soluble molecules. Unlike sugar, it has a very mild, neutral flavor profile—so it doesn’t overpower added fruit extracts or proteins, which is perfect for brands that want their core ingredient (like plant protein or prebiotic fiber) to shine. It also has an extremely high solubility rate: 95% or more dissolves in cold water, which is non-negotiable for most clients, especially those targeting on-the-go consumers who mix powders in shaker bottles at the gym or office. The other big win for maltodextrin is shelf stability: it has a low hygroscopicity, meaning it doesn’t absorb moisture from the air easily. That prevents the powder from caking or clumping in storage, which is a huge pain point—no brand wants a customer opening a fresh container of their drink mix only to find hard lumps. The only time we don’t use maltodextrin as a base is if a client is making a sugar-free or low-carb product; in those cases, we swap it for inulin, a prebiotic fiber made from chicory root that works almost identically for solubility and bulk, while adding a gut-health benefit that’s become a major selling point in the last five years.
Next, the macronutrient and functional core ingredients—this is what the brand is marketing, so we have to be incredibly precise here. For protein drinks, whey protein concentrate and isolate are the go-to for traditional clients, but we work with a lot of plant-based protein too now: pea, rice, hemp, and soy protein isolates. These are more finicky than maltodextrin, though. Plant proteins, for example, have a stronger, earthy beany or grassy flavor that can be off-putting to consumers, so we usually pair them with flavor masks like natural vanilla extract or citric acid to balance that out. Also, solubility is a big challenge here; plant proteins can clump in cold water if not processed correctly, so we’ll often do a micronization step (grinding the protein into ultra-fine particles) or add a small amount of lecithin to reduce surface tension between the protein molecules. For meal replacement shakes, we’ll add whey protein isolate (which has 90%+ protein by weight, almost no fat or carbs) or rice protein isolate, plus complex carbohydrates like oats or quinoa flour to provide sustained energy, and sometimes healthy fats like medium-chain triglyceride (MCT) oil powder. That’s a specific ingredient that’s come into huge demand in the last decade: MCT oil is liquid at room temperature, so to turn it into a powder that mixes evenly, we microencapsulate it with a starch or protein coating. That process keeps the fat from separating and gives it the same shelf stability as the rest of the powder. For pre-workout drinks, we’ll add creatine monohydrate (the most researched form of creatine, which is 100% soluble in cold water when processed correctly) and beta-alanine, an amino acid that reduces muscle fatigue. For probiotic drinks, we use freeze-dried bacterial strains (like Lactobacillus or Bifidobacterium) instead of liquid ones because freeze-drying keeps the bacteria alive longer in powder form—though we have to be careful to add them at the final mixing step, because heat from manufacturing would kill them.
Then come the functional additives—small amounts of ingredients that make a big difference, and ones that most consumers never even see listed on a nutrition label, but we couldn’t make a good solid drink without them. Emulsifiers are the first one I think of. We use sunflower lecithin or soy lecithin almost every day to ensure all the ingredients mix evenly and don’t separate once the powder is dissolved. For example, if a drink has oil-soluble vitamins like vitamin D or omega-3s, they need to be coated with an emulsifier so they disperse throughout the water instead of floating on top as a thin film. Thickeners and stabilizers are another category, though we use them sparingly—usually less than 1% of the total formula—because we don’t want to make the drink feel chalky or gummy. Xanthan gum is the most common; it’s a natural polysaccharide derived from bacteria that adds a smooth texture without affecting flavor, and it helps prevent the powder from settling at the bottom of the container when stored. For sugar-free products, we use sugar alcohols like erythritol and stevia extract as sweeteners, which are low-calorie and don’t spike blood sugar. But these have their own quirks: erythritol has a cooling aftertaste that some consumers find unpleasant, so we’ll often blend it with a small amount of sucralose or monk fruit extract to round out the flavor and reduce that cooling effect. Flavors and colorants are also huge, and we prioritize natural ingredients as much as possible now—consumers are demanding fewer artificial additives, so we use natural fruit and vegetable extracts (like beet juice for pink color, strawberry extract for flavor) instead of artificial dyes and flavorings. For a mango drink, for example, we’ll use a combination of mango powder (made from dehydrated mango puree) and a natural flavor extract to get that bright, juicy taste, without any artificial compounds.
Wait, I should also mention processing aids, though they’re not usually listed on the final nutrition label because they’re removed during production. Things like anti-caking agents, for example—silicon dioxide is a common one we use in very small amounts (less than 0.02% of the formula) to prevent the powder from clumping during packaging and shipping. It’s safe, it’s inert, and it doesn’t affect the taste or nutrition of the final product. We also use flow agents, like magnesium stearate, to make sure the powder flows smoothly through our mixing and packaging equipment—no one wants a machine getting clogged halfway through a production run.
One thing I always emphasize to new clients is that OEM/ODM for solid drinks isn’t a one-size-fits-all process. A formula that works for a protein shake will never work for a pediatric probiotic powder, because the requirements are totally different. For example, pediatric products need to be extra gentle on sensitive tummies, so we avoid any ingredients that might cause irritation, and we use smaller particle sizes so they mix well with milk or water for kids. Sports nutrition products need to be high in protein and electrolytes, so we add things like sodium chloride (table salt, in small amounts), potassium chloride, and magnesium citrate to replace what’s lost during sweat. Herbal supplements, another big category for us, use dried herbal extracts instead of just fruit or protein, and we have to test those extracts for heavy metals and purity, which is a non-negotiable step for every batch we produce.
I’ve seen a lot of new brands come to us with a great concept, but they don’t realize that the ingredients they pick have a huge impact on how the product performs. For example, a startup once wanted to launch a low-sugar chocolate protein powder that used 100% whey concentrate, no other base. The problem was whey concentrate is more expensive than maltodextrin, and it has a higher fat content, which makes it more hygroscopic—so the powder would clump in the bag within a month. We worked with them to adjust their formula: we kept their core whey protein, added a small amount of maltodextrin to improve shelf stability, used stevia and erythritol to sweeten it, and added a flavor mask to cover the whey’s natural slight bitter taste. The end product was exactly what they wanted, but it only worked because we understood how each ingredient interacts, not just what’s in the formula.
Another common misconception is that OEM solid drinks are “low-quality” compared to brands that make their own products. That’s not true at all. We follow GMP (Good Manufacturing Practices) guidelines for every batch, we test each incoming ingredient for purity and nutrition content, and we do three quality checks during production: pre-mixing to check ingredient ratios, mid-mixing to check homogeneity, and post-packaging to test solubility and shelf life. We work with brands from tiny, founder-led startups to large multinational companies, and the core ingredients we use don’t change based on who the client is—only the ratios and additives do.
If you’re a brand owner looking to launch your own solid drink, whether it’s a new protein line, a functional herbal drink, or a pediatric nutrition powder, understanding these common ingredients is a good first step. But the best part of working with an OEM/ODM partner like mine is that we don’t just mix powders—we guide you through every choice, from picking the right base ingredients to avoiding common pitfalls like poor solubility or short shelf life. We test every formula, adjust as needed, and make sure the final product is exactly what your consumers want: a drink that mixes easily, tastes good, delivers on its nutrition or function, and stays fresh for months.
