We're the only ones out there who can make a carb-free, clear drink like Zero Carb — the microfiltration process used to create Isopure Protein is so complete it creates the only completely clear milk protein when dissolved in water, meaning this drink looks and pours like a sports drink, not a milkshake. Lactose-free and gluten-free, so you can better your body without discomfort. Non-GMO. Zero carb, zero sugar, zero fat. Shake well before drinking. Take 1 bottle after a workout or other strenuous activity, or anytime throughout the day. Refrigerate after opening. Store in a cool, dry place away from direct sunlight.

Made with protein so pure you can't see it — Isopure's microfiltration process is what makes this genuinely different from a standard protein shake. Conventional whey protein mixed in water produces an opaque, milky-white liquid because of residual fat, lactose, and other milk-derived compounds that remain even after typical processing. Isopure's microfiltration strips the whey protein down to a level of purity where the resulting liquid is truly transparent — the same clarity as a flavored water or sports drink rather than anything resembling a milkshake. This isn't achievable with standard whey isolate processing; it requires the specific filtration standard Isopure built its brand around, and the company states plainly that they're the only ones who can make a carb-free, clear drink like Zero Carb.†
At 130 calories with 32g of protein and a true 0g of carbohydrate, Zero Carb Protein Drink is built specifically for anyone tracking macros with precision — keto dieters, individuals in a strict cut, or athletes managing carbohydrate intake around a specific competition or physique goal. Because carbohydrate content is genuinely zero (not "low carb" or "net carb" adjusted), this RTD slots into a carb-restricted diet without requiring any accounting adjustment — a meaningful practical advantage over shakes or bars that claim low-carb status but still carry several grams that need to be tracked.†
The 10.2g of BCAAs (Branched-Chain Amino Acids — Leucine, Isoleucine, and Valine) in each bottle come directly from the whey protein isolate itself rather than being added as a separate supplemented ingredient. Whey protein isolate is naturally one of the most BCAA-dense complete protein sources available, and whey's fast digestion and absorption rate makes it a well-suited protein source for delivering these muscle-protein-synthesis-triggering amino acids quickly to circulation — particularly relevant for the post-workout window this RTD is specifically positioned around.†
Zero Carb uses 100% whey protein isolate rather than whey concentrate — isolate undergoes additional filtration that removes the vast majority of lactose (milk sugar) along with most of the fat and carbohydrate content that concentrate retains. This is why Isopure Zero Carb can claim both zero carbs and lactose-free status simultaneously — the same filtration process responsible for the drink's clarity is also what strips out the lactose that causes digestive discomfort in lactose-sensitive individuals, letting you better your bod without discomfort.†
Why is this drink clear instead of milky like a normal protein shake?
Isopure's microfiltration process removes essentially all of the fat, lactose, and other milk-derived compounds that typically make protein shakes opaque — the resulting whey protein isolate is pure enough that when dissolved in water, it produces a genuinely transparent liquid rather than the cloudy, milky appearance of standard protein shakes.†
Is Zero Carb Protein Drink actually zero carbs, or is that rounded?
The label states a true 0g of total carbohydrate per 16 fl oz bottle — this reflects the extensive filtration whey protein isolate undergoes, which removes essentially all residual lactose and carbohydrate content that would otherwise appear on the label.†
Can Zero Carb Protein Drink replace a meal?
No — this product is intended as a food supplement only and is not designed for weight reduction or meal replacement. At 130 calories and 32g protein with zero carbs and minimal other macros, it's best used to supplement daily protein intake around training or between meals, not as a complete nutritional meal substitute.†
Is there a powder version with the same specs?
Isopure also sells Zero Carb as a powder (25g protein per scoop, mixed with water or milk), which has a different serving size and slightly different macro profile than the RTD bottle's 32g protein and 130-calorie specs. If you specifically want the 32g protein, zero-carb, 130-calorie RTD profile, the bottled drink is the correct product — the powder is a separate SKU with its own label.†

"I’ve always been one to dislike the taste of plant based and whey protein powders. The Isopure is a different story. Love the flavor, taste and texture of a “juice” styled drink while packing in lots of protein! Drink it iced cold/chilled and it’s gooodt!"
