Advancements in ingredient technology and nutrition science have empowered Isagenix to transition from our time-tested “classic” IsaLean® Protein Shakes into a significantly enhanced version.  

The updated shakes include premium MCT oil, enhancing the formula to support better energy and satiety. Find everything you need to know about the upgrade here

Here are additional FAQs about the IsaLean Shakes with MCT oil:

1) How many meals per day can I replace with an MCT oil IsaLean Protein Shake? 

Just like the previous IsaLean Protein Shakes, the evolved shakes can replace two to three meals per day depending on caloric needs and weight loss goals. 

2) Can I add other ingredients to customize my IsaLean Protein Shake? 

Yes, you can customize your Isagenix System to meet your needs. In fact, we often share new ways to use your IsaLean Shakes for variety in taste, texture, routines, and more. Stay tuned for delicious new recipes coming soon! 

Remember that adding extra ingredients to your IsaLean Protein Shake increases the caloric intake, which can influence where and when you fit the shake into your daily routine. 

3) What type of protein does the IsaLean Protein Shake contain? 

IsaLean Protein Shakes still contain 24 grams of high-quality protein, including undenatured whey protein concentrate and milk protein concentrate from pasture-raised, grass-fed cows not treated with hormones or routine antibiotics.  

The Plant-Based IsaLean Protein Shake contains the same protein content and a similar complete amino acid profile derived from fava beans, mung beans, and pea proteins. Currently, plant-based shakes do not include MCT oil. 

4) What is different about the updated formula for IsaLean Protein Shakes? 

As mentioned, the new shakes contain MCT (Medium-Chain Triglyceride) oil. MCT’s are unique fats that the body can rapidly absorb and convert into usable energy without storing them as body fat. This means your IsaLean Protein Shakes will make you feel more fueled and satisfied, and not heavy or overly full.  

Our shake evolution does not mean customers must change the way they consume IsaLean Protein Shakes. In fact, customers have noted that the updated shakes taste better, mix more smoothly, and are creamier than the prior versions.

The IsaLean Shakes you trust for meal replacements and protein boosts are still here, now with MCT oil to ensure smarter energy, greater satisfaction, and an overall improved experience in taste, texture, and beyond.
