Of the three macronutrients — protein, carbohydrates, and fat — protein often gets the spotlight. Protein supports better weight loss, can help build and maintain muscle mass, and keeps you satiated after a shake or meal. The amount and type of protein you need depends on your personal goals.

There’s an Isagenix protein shake for everyone, but which shake is best for you? Use this guide to pick the perfect shakes for ultimate results.

IsaLean Shake

IsaLean® Shake is one of our core products and a popular introduction to Isagenix and our weight loss packs. In fact, to call it a “shake” doesn’t give IsaLean Shake its due, as this is a complete meal replacement. Just look at everything you get in one 240-calorie serving:

  • 24 grams of whey and milk protein.
  • 24 grams of energy-fueling carbohydrates.
  • 8 grams of filling fiber (included in the 24 grams of carbs).
  • 5 grams of good fats.
  • 23 vitamins and minerals to nourish an active lifestyle.

That’s complete. Millions of people across the world have achieved incredible results and transformations using IsaLean Shake and the Isagenix System, making it the perfect shake for anyone starting their weight loss journey.

Plus, there’s five delicious flavors to choose from with limited-edition flavors always on the horizon.

IsaLean Shake Plant-Based

Plant-based nutrition is trending in health and wellness and for good reason. While whey protein is fantastic for people targeting weight loss and muscle building, anyone with a dairy intolerance or other allergies can benefit more from IsaLean Shake Plant-Based.

It uses a sophisticated blend of pea and brown rice protein to deliver a similar protein boost as IsaLean Shake with an equally amazing taste! Who knows…try it out, and you might even prefer the flavor!

IsaLean PRO Shake

There’s a myth that IsaLean PRO Shake is just for gym rats and bodybuilders, but that’s all it is: a myth. While consuming more protein alongside weight and resistance training is great for muscle growth, it also serves as a powerful weight loss tool, helps you feel fuller, and is perfect for breaking through plateaus.

That’s where IsaLean PRO Shake works its magic. It’s a meal replacement, like IsaLean Shake, but it features 36 grams of high-quality whey and milk protein instead of the 24 grams found in IsaLean Shake.


Here’s a scenario: You order IsaLean Shake as part of your weight loss pack and realize a few weeks into the journey that you want more protein in your shake or something to add to your favorite recipe.

Instead of stuffing your IsaLean Shakes in the back of the cupboard and paying for IsaLean PRO as a replacement, grab a canister of IsaPro®, and add a scoop to your current shake for a protein boost. Of course, this is only one of many reasons to stock IsaPro in your cupboard. Each 90- to 100-calorie serving packs 18 grams of whey protein concentrate and is perfect on its own, as an additive to your IsaLean Shake, or as a versatile ingredient in a healthy recipe.

So, which protein is right for you? There’s a good chance you’ll try more than just one through your Isagenix health and wellness journey, and that’s the beauty of it! There’s no “one right person” for “one right protein.” Maybe you start out with IsaLean Shake, try the plant-based variety, and upgrade to IsaLean PRO. You have the freedom of customization!
