Protein Powder Without Sucralose

Is Sucralose Bad for You?

Sucralose is an artificial sweetener found in many, if not most, protein supplements.

It was accidentally discovered in 1976 and popularized in the early 2000s by Splenda, the sweetener in the little yellow packet.

Sucralose is hundreds of times sweeter than sugar, but virtually calorie-free, making it seem like a healthy alternative to sugar.

But that could not be further from the truth.

For starters, studies have found little to no relationship between changes in body weight and the use of low-calorie sweeteners.

On average, people who replace sugar with low-calorie sweeteners like sucralose lose less than two pounds (Int J Obes (Lond), 2013)

Studies have found that people who use artificial sweeteners might actually gain weight because they indulge themselves after having “saved calories” with their diet soda, sugar-free ice cream, etc (CMAJ, 2017; Cell Metab, 2016).

The real concern with artificial sweeteners like sucralose, however, is how they affect your gut microbiome.

Regularly consuming sucralose can alter the composition and function of your gut microbiome (Adv Nutr, 2019).

Over time, this can lead to gut dysbiosis, which has been shown to contribute to the development and progression of a number of chronic conditions, including metabolic, cardiovascular, gastrointestinal, neurological, and immune-related diseases (Nutr Rev, 2025).

What Is the Best Sucralose-Free Protein Powder?

To know if a protein powder contains sucralose, check the ingredient list on the Nutrition or Supplement Facts panel.

And while you are there, check to see if there are any other artificial sweeteners listed.

Other common artificial sweeteners include acesulfame potassium and aspartame.

Once you confirm that a protein powder is in fact sucralose-free, you might then want to consider which sweetener was used.

The options are real sugar, sugar alcohols like erythritol and xylitol, or natural sugar substitutes like stevia and monk fruit.

Every type of sweetener has advantages and disadvantages.

We use monk fruit because it is both the best tasting and best for you.

Monk fruit, also known as luo han guo, is a melon-like fruit native to Southeast Asia.

It is almost sugar-free, but sweet like sugar thanks to compounds called mogrosides.

Other sugar substitutes, especially stevia, activate bitter taste receptors in addition to sweet taste receptors, giving them a bitter aftertaste (J Agric Food Chem, 2016).

It is worth adding that although monk fruit sweetener has only been commercially available for about a decade, it has been safely used in Asian cuisine for centuries.

And unlike real sugar, it does not negatively impact blood sugar or insulin levels (Eur J Clin Nutr, 2017).
