As a fitness enthusiast or an endurance or strength athlete, you probably take some type of protein as part of your diet regimen. Proteins are the building blocks of life as every cell in the human body contains protein – playing a vital role in the formation of hormones, skin, enzymes, tendons, and other molecules.
It doesn’t, therefore, come as a surprise why protein powders have become popular. They help enhance recovery, increase strength, decrease body fat, and gain muscle mass.
Unfortunately, there are protein powders marketed to contain “the best ingredients,” but are not really pure and additive-free. Meaning, they contain artificial sweeteners that are not as healthy as you may think.
These synthetic sugars can neutralize your workout and diet efforts and some may have serious side effects. That is why we looked into some of the best protein powders in the market today without artificial sweeteners for your choosing.
These protein powders were combed through the manufacturing practices and the ingredients, taste-tested, and are those we consider as among the cleanest in the market. But before that, allow us to briefly discuss the truth about this sugar alternative.
What’s the Deal with Artificial Sweeteners?
Artificial sweeteners are derived from natural substances, such as herbs or sugar itself. One of its therapeutic uses is to assist in weight loss (slightly, at best) by lowering energy intake.
Next, they limit actual sugar intake (helpful for people with diabetes in regulating their blood sugar levels), and dental care among children (they do not encourage dental decay as they are not fermented by the microflora of the dental plaque), according to a study.
However, artificial sweeteners are the worst type of sweetener. They may increase cravings for sweet and sugary foods in the long run. They are also linked to a higher risk of glucose intolerance, which may lead to pre-diabetes and diabetes.
There were also epidemiological studies that showed a positive correlation between weight gain and artificial sweeteners. Moreover, artificial sweeteners are metabolized differently in people’s bodies due to their different properties.
Clearly, the pros and cons of artificial sweeteners consumption is still a topic of debate within society at large, specifically among the scientific community. Now, let’s proceed with what we think are among the best protein powders out there that are free of artificial junk!

What to Look for When Buying a Protein Powder Without Artificial Sweeteners
Since what we’re looking for is a protein powder without artificial sweeteners, it is important to check the ingredients of the product first. Artificial sweeteners may be in the form of sucralose, aspartame, acesulfame potassium, and any other synthetic sweetener.
If you see any of those in the ingredient list, avoid that protein powder. Keep in mind also that some proprietary artificial flavor formulas are artificial sweeteners. So, if you can avoid those with proprietary blends, the better.
Protein Type and Uses
One of the most commonly used protein powders is whey protein and is ideal for day-to-day use. It is because it is easily digested and contains all the essential amino acids. It also helps reduce stress levels and boost energy.
Here’s a quick comparison between animal protein (whey protein originally starts with cow’s milk) and plant protein:
Whey concentrates and isolates, on the other hand, are protein types that are best-used post-workout. At best, choose a protein powder that matches your needs. Is it for muscle growth? For weight loss? To stay vegetarian? To control your weight? To recover after workouts?
The meat, dairy, and poultry industries have a history of hormone use as beef cattle ranches and dairy farmers are trying to boost meat and milk production efficiency.
However, the use of synthetic growth hormones in beef and dairy cattle can make their way into products that people consume. Meaning, these can be harmful not just to animals but to humans too.
So, if possible, see the “rbGH-free” label when buying a milk product or a protein powder.
Nutritional Efficiency/ Protein Quality
Lastly, consider the nutritional efficiency or the protein quality. There are some scales developed to rate the proteins based on their amino acid profiles and bioavailabilities. A protein is highly bioavailable if it is easy to absorb, easy to digest and make into other proteins.
A protein is considered complete in amino acid profile when it is proportional to its overall amino acid content. Of the animal-based protein powders, whey protein had the highest (43%) essential amino acid content and calcium caseinate (38%) an intermediate amino acid content.
Final Verdict: Which One Should You Buy?
Take control of your flavors today! Choose one from this list that has the natural benefits of protein powder but is not necessarily tasteless (go ahead if you prefer the unflavored version).
We all have different criteria when looking for the best protein powder without artificial sweeteners, but if you ask us what’s our top pick from this list, it would be the NutraBio 100% Whey Protein Isolate with Complete Amino Acid Profile.
In terms of ingredient quality, blending power, and flavor, it’s really a win. Per scoop, it already contains 25g of protein. It is even gluten- and soy-free, contains zero fillers, is non-GMO, and unflavored.
Its unflavored taste may not appeal to all, but it has undergone a third-party test for purity. It’s also low in kosher dairy and cholesterol. All these features make NutraBio 100% (for us) the best overall protein powder without artificial sweeteners.
