Pure, Simple, & Powerful: A Deep Dive into ISOPURE® Clear Protein’s Ingredients

When it comes to protein, less is more—especially when every ingredient serves a purpose.

ISOPURE® Clear Protein (formerly Isopure Infusions) isn’t your typical creamy shake. It’s a refreshing protein drink made with only five purposeful ingredients and delivers 20 grams of whey protein isolate—with zero carbs and zero sugar.

Whether you’re looking for a light, low carb protein drink to fuel your day or just tired of heavy, milky shakes, this crisp fruit-flavored option is a refreshing change.

Let’s take a closer look at what makes this protein innovation so unique—and why each ingredient earns its place in the bottle.

1. Whey Protein Isolate

The hero of the formula. This is the purest form of whey protein, stripped of fat, carbs, and lactose—leaving behind fast-digesting, high-quality protein to support muscle recovery and your active lifestyle. Isopure is known for going the extra mile when it comes to protein purity, and this clear protein drink is no exception.

Why it matters: Unlike traditional milky shakes, the whey protein isolate in ISOPURE® Clear is designed to be fully soluble and light, giving you fruit-flavored refreshment without the chalk or clump.

2. Citric Acid

This naturally occurring compound (found in citrus fruits) is used to enhance tartness and preserve freshness.

• Why it matters: It gives each sip a crisp, tangy brightness—key for that light, juice-like experience that sets this low carb protein drink apart.

3. Natural Flavor

Only natural flavors are used to give each variety its clean, fruity taste—whether it’s Citrus Lemonade, Mango Lime, or another refreshing option.

• Why it matters: It’s part of what makes this high protein drink feel more like a thirst-quenching beverage than a heavy protein shake.

4. Stevia Leaf Extract

Sweetened with stevia—derived from the leaves of the stevia plant—this formula skips the sugar without compromising taste.

• Why it matters: You get a subtly sweet finish with zero sugar, no artificial sweeteners, and no lingering aftertaste.

5. Beta Carotene (for color)

Beta carotene is a plant pigment found in carrots and other colorful vegetables. It’s used here to give the drink a natural, vibrant hue.

• Why it matters: Instead of artificial dyes, ISOPURE® Clear Protein uses this recognizable ingredient to keep the formula straightforward and naturally vibrant.

Why It’s Different

What sets ISOPURE® Clear Protein apart isn’t just what’s in it—but what’s not. No artificial colors. No unnecessary fillers. No sugar. No thick texture. Just five ingredients. And 20 grams of high-quality, whey protein isolate.

This isn’t your average shake—it’s protein made refreshing.
