According to the National Center for Health Research, many protein powder brands contain as much as 23 grams of sugar. This amount can undermine the health benefits and cause undesirable side effects. Sugar-free protein powder offers all the remarkable benefits of customary protein powders without the negative effects of added sugar. (1)

Numerous sugarless brands are in the market, promising the best results without compromising your blood sugar. So it takes work to make an informed choice. Fortunately, this article will guide your powder picking, covering sugar-free protein powder benefits, the best brands, and how to choose the right product.

What Is Sugar-Free Protein Powder?

In essence, sugar-free protein powder is a reliable supplement providing the typical benefits of protein without the added sugar that mostly features in traditional protein powders. As a result, users consider it a healthier alternative for promoting muscle growth, recovery, and overall fitness.

Besides their restricted calorie content, sugar-free protein powders supply your body with the necessary nutrients to build muscle. According to the USDA, a scoop of whey powder (equivalent to 19.5 grams) contains (but isn’t limited to) the following vital components:

  • Fat – 1g
  • Calories – 75
  • Sodium – 75mg
  • Fiber – 0g
  • Carbohydrates – 3.5g
  • Sugars – 1g
  • Protein – 13g

Research findings also show that protein supplementation can have a satiating effect, suppressing your appetite and regulating cravings and hunger. So you can incorporate the product into your weight loss program. (2)

Enjoying protein powder without consuming 1g or more of sugar can help you healthily achieve muscle growth.

Most manufacturers create powders out of quality, natural ingredients. So the supplement is easy for your body to digest and absorb. These protein powders are tremendously versatile and can be part of almost any recipe.

Notably, most sugar-free protein brands will claim to have ditched sugar, but you can never be too sure. You should review the label and ingredient list to ascertain whether the product you’re considering is truly sugar-free, contains a tiny percentage, or is filled with the sweet stuff.
