Core Power gets its high protein content entirely from real milk, not from added protein powders or concentrates. The secret is an ultrafiltration process that essentially concentrates the natural protein in cow’s milk while stripping away water, sugar, and other smaller molecules. A standard bottle contains either 26g or 42g of complete protein, depending on the version, all from milk alone.
How Ultrafiltration Concentrates Milk Protein
Regular cow’s milk contains about 8 grams of protein per cup. That protein is there, but it’s diluted by water, lactose (milk sugar), and dissolved minerals. Core Power uses a membrane filtration technique to change that ratio dramatically.
The process works by pushing milk through a semipermeable membrane with tiny pores. Protein molecules are large, so they can’t pass through and get retained on one side of the membrane. Water, lactose, and smaller dissolved minerals pass right through and get removed. What you’re left with is milk that has a much higher concentration of protein relative to everything else. Think of it like a very precise strainer that sorts molecules by size.
This is the same basic technology used across the food and beverage industry. In dairy specifically, ultrafiltration retains high molecular weight components like milk proteins while letting low molecular weight components like lactose and soluble minerals flow through. The result is a product that tastes like milk, because it is milk, but with roughly two to five times the protein content of a regular glass.
No Added Protein Powders
One of the most common assumptions is that Core Power must be blending in whey protein isolate or some other supplement powder to hit those numbers. It doesn’t. The ingredient list for the 42g Elite version is straightforward: filtered lowfat Grade A milk, plus small amounts of natural flavors, sweeteners, stabilizers, and added vitamins A and D. No whey powder, no casein powder, no plant protein blends.
The protein in Core Power is the same mix naturally found in cow’s milk: roughly 80% casein and 20% whey. Both are complete proteins, meaning they contain all nine essential amino acids your body needs. Casein digests slowly, providing a sustained release of amino acids, while whey digests faster. This combination is one reason Core Power is popular as a recovery drink after workouts.
Standard vs. Elite: Why the Protein Differs
Core Power comes in two tiers. The standard version provides 26g of complete protein per bottle, while Core Power Elite provides 42g. The main difference is simply how concentrated the milk is. The Elite version goes through a more aggressive filtration or uses a higher volume of ultrafiltered milk to pack nearly double the protein into the same size bottle. Both versions use the same approach: no powders, just more concentrated milk.
For context, getting 42g of protein from regular milk would require drinking roughly five cups. Core Power Elite delivers that in a single 14-ounce bottle.
What Happens to the Sugar
Concentrating protein this much would normally mean concentrating everything else in milk too, including lactose. But the filtration membrane handles that problem automatically. Because lactose molecules are small compared to protein molecules, most of the lactose passes through the membrane and gets removed along with the water.
Whatever small amount of lactose remains after filtration is broken down by a lactase enzyme added to the product. This converts the leftover lactose into simpler, more digestible sugars. The end result is a product that’s lactose-free and significantly lower in sugar than regular milk, even though it started as ordinary cow’s milk. A bottle of Core Power typically has around 5 to 7 grams of sugar, compared to roughly 24 grams in two cups of regular milk.
Why It Costs More Than Regular Milk
The price tag on Core Power reflects what’s happening behind the scenes. You’re essentially paying for a much larger volume of milk than what ends up in the bottle. To concentrate that much protein into 14 ounces, you need to start with substantially more raw milk and then remove most of the water and sugar. The ultrafiltration equipment, the multi-step processing, and the shelf-stable packaging all add to the cost. It’s not a markup on a commodity product; it’s a fundamentally different manufacturing process that turns several servings of milk into one dense, high-protein bottle.
