How to Choose a Sugar-Free Protein Powder - Buying Guide

When choosing a sugar-free protein powder, there are many factors to keep in mind, including the type of sweeteners, the amount of protein per serving, and the protein sources. Keep reading to learn more! 

Look Into Different Sugar Alternatives

Look Into Different Sugar Alternatives

Some sugar-free protein powders are completely free from sweeteners. They have no flavor and won't alter the taste of drinks or food. Therefore, you can easily incorporate sugar-free protein powders in shakes, smoothies, desserts, or savory dishes. 


If you prefer flavored and sweetened protein powders, there are still many sugar-free options for you to choose from! Instead of sugar, they usually contain sweeteners such as sucralose, monk fruit extract, and stevia. 


Sucralose, also known as Splenda, is an artificial sweetener that's 600 times sweeter than table sugar. It's derived from table sugar and doesn't have an unpleasant aftertaste. It also doesn't have any calories. But, sucralose might raise the blood sugar and insulin levels of those who do not consume sucralose frequently. 

Look Into Different Sugar Alternatives

If you don't want to consume artificial sweeteners, look for protein powders with natural sweeteners like monk fruit extract or stevia. Monk fruit extract contains no calories and is approximately 150 to 250 times sweeter than table sugar. 


Stevia is another natural sweetener commonly used in sugar-free protein powders. It's derived from stevia plants and is about 200 to 400 times sweeter than table sugar. It doesn't raise your blood sugar and is a good choice for people with diabetes. 


The differences between monk fruit extract and stevia come down to their flavor. Monk fruit extract has a slight fruity flavor, while stevia has a mild taste with a bitter aftertaste. 

Choose a Protein Source That Works for You

Protein can be derived from many sources, including whey, casein, egg, and pea. Continue reading to learn about protein sources commonly used in sugar-free protein powders. 

Whey Protein Digests Quickly and Is Great After a Workout

Whey Protein Digests Quickly and Is Great After a Workout

Whey protein is derived from cow's milk. It usually has a smooth and creamy texture. It's also a complete protein source and can provide you with all of the essential amino acids. 


Whey protein also contains branched-chain amino acids (BCAAs) such as leucine, isoleucine, and valine. These BCAAs can only be obtained from foods. They help reduce muscle breakdown and boost muscle growth. 


Whey protein is a fast-digesting protein. It's ideal to consume after exercise since your body is exhausted and needs protein to rebuild muscle. Also, depending on the processing method, whey proteins can have very low to virtually no lactose content. If you're lactose-intolerant, check the packaging to ensure it works for you. 

Casein Protein Can Help Grow Muscle While You're Sleeping

Casein Protein Can Help Grow Muscle While You're Sleeping

Just like whey protein, casein protein is derived from cow's milk and contains all of the essential amino acids. However, unlike whey protein, casein digests slowly. It's best taken before bed as it can help reduce muscle breakdown and increase gains in muscle while you're sleeping. 


Some protein powders use micellar casein, which is the least processed and most natural form of casein. However, there haven't been any studies showing that micellar casein is better than regular casein. 

Plant-Based Protein Has a Lot of Vitamins and Minerals

Plant-Based Protein Has a Lot of Vitamins and Minerals

Many sugar-free protein powders are made with plant-based protein sources such as pea, hemp, quinoa, and rice. Pea protein tastes slightly earthy and has all nine essential amino acids. It's also rich in iron and can be absorbed quickly by the body. Plus, it contains a high amount of fiber and can keep you feeling full for a while.


Hemp protein is also a complete protein and has a nutty, slightly grassy taste. It contains high levels of fiber, omega-3 and omega-6 fatty acids, and magnesium. Quinoa protein is a good source of fiber, antioxidants, and minerals like iron. It's a complete protein and has a nutty flavor.


Rice protein is another excellent plant-based protein source. It's low in lysine and isn't a complete protein. However, it is easy to digest and is rich in fiber as well as B vitamins. Its neutral taste makes it easy to incorporate into different dishes and drinks. 

Consider a Powder Infused With Extra Nutrients

Consider a Powder Infused With Extra Nutrients

A lot of sugar-free protein powders are infused with extra nutrients to provide you with more health benefits. If you need an extra nutritional boost, consider a fortified protein powder! 


Some contain digestive enzymes to support your body's nutrient intake, while others are formulated with vitamins and minerals to supplement your nutritional needs. There are also protein powders enriched with MCT oil, a source of medium-chain triglycerides that can help boost your energy and enhance your body's metabolism.
