Artificial sweeteners are sugar substitutes made synthetically that taste similar to natural sugars. They usually do not contain any calories, so they will have minimal impact on your metabolism. Many companies use them when they flavor their protein powders. They are considered controversial and may have several negative side effects. Here’s a look at the currently FDA approved artificial sweeteners: 

  • Acesulfame K – Also known as acesulfame potassium. It’s about 200 times sweeter than regular sugar, and it’s sold under the brand names Sweet One and Sunett. You’ll find it in many sports nutrition supplements, especially pre-workout and protein powders. (1)
  • Aspartame – This artificial sweetener consists of two amino acids: aspartic acid and phenylalanine. It’s sold under the brand names NutraSweet and Equal. (2)
  • Neotame – This is as common as the other artificial sweeteners on this list. Produced by the makers of NutraSweet, it is considerably sweeter than sugar and is considered similar to Aspartame. (3)
  • Saccharin – This sweetener is 300-400 times sweeter than sugar. It’s made from the chemical phthalic anhydride, a compound used in the manufacture of plastics. (4)
  • Sucralose – This is made from sugar and sold under the brand name Splenda. It’s 400-700 times sweeter than sugar. It’s advertised to be calorie-free yet it contains 3 calories per gram. However, since only very small amounts are required any calories ingested are minimal. (5)

Some of the claims against artificial sweeteners are that they may inhibit weight loss and increased hunger. Another claim is that they increase blood sugar, blood pressure, and may contribute to excess belly fat. There are also claims that they may cause cancer. (6, 7, 8, 9)

Natural sweeteners are becoming a popular replacement for sugar and artificial sweeteners. Compounds such as stevia and monk fruit are considered to be healthier options. You will see either of these two in many “natural” protein powders. Let’s take a brief look at each:

Stevia – This natural sweetener comes from the leaves of the stevia plant. This plant is commonly found in countries such as Brazil and Paraguay. It has 30-150 times the sweetness of sugar and is not metabolized by the body. There are no reported negative side effects at this time. (10)

Monk Fruit – This natural sweetener originates in southern China and northern Thailand. It has 150-250 times the sweetness of sugar and has zero calories. At this time, it has no reported negative side effects. (11)

The three macronutrients required by the body are protein, carbohydrates, and fats. 

Protein is considered to be the most important. While our bodies consist of apporximately 60% water, but most of our dry weight is made of protein. 

One of the main components of protein is amino acids. They are commonly called the “building blocks” of protein. This is because they are used in countless sequences, or chains, which then control hundreds of daily functions in the body. 

Not all amino acids are made in the body, some must come from food and supplements. This means that daily protein needs must be met, therefore, protein must be ingested throughout the day. 

Your daily protein should come from whole foods and quality protein powder. 

Sufficient daily protein is important for everyone. This is especially true for bodybuilders, athletes, and anyone that regularly exercises. (12, 13)

In terms of fitness, protein provides the following benefits:

  • Promotes Muscle Growth
  • Supports Post-Workout Recovery
  • Helps The Body Maintain An Anabolic Environment
  • Helps Promote Fat Loss
  • Prevents Catabolism 

There are quite a few sources of high-quality protein available on the market. Most companies make various types of protein powder. The better companies offer at least one option that’s natural, meaning it will have no artificial sweeteners or any other artificial ingredients. 

Whey Concentrate – This is the most common form of whey protein. It’s 80% protein with the remaining 20% consisting of carbs and fats.

Whey Isolate – This is the highest quality form of whey, and is considered the best protein you can buy. It will be at least 90% protein. 

Egg White – Before the introduction of whey, egg white protein was considered the best protein you could buy. It’s a superior protein that has a medium rate of digestion. 

Casein is a high-quality protein that’s known as a slow-digesting protein. There are mainly two types of casein:

Calcium Caseinate – This is the most common form of casein protein. It’s taken from the insoluble part of milk and then undergoes a purification process to make it usable. 

Micellar Casein – This is the purest form of casein protein available. This is the type of casein to look for in a good protein powder.

Milk Protein Isolate – This is a high-quality blend of casein and whey. This offers the fast and slow digestion benefits of both.

Plant-Based – This can be any combination of plant-based proteins. Pea and brown rice are the most common, but some powders include as many as 14 plant-based protein sources in their product. This is a medium digesting protein powder that has become a hot trend in recent years.  

Beef – This has become a common protein source in recent years and is used primarily in Paleo and low carb diet protein powders. It’s also a good protein for bodybuilding and powerlifting.

Here’s what to look for in a protein powder that does not contain artificial sweeteners: 

  • Quality Ingredients – Look for high-quality protein and the cleanest possible formula. That means no artificial ingredients, fillers, or additives. Many of the choices in this guide only contain 1-2 ingredients.
  • Protein – Look for at least 20g of protein per serving, anything less isn’t worth it. Most protein powders range from 20g to as high as 30g. Some powders may require 2 scoops for a 30g serving.
  • Value – Don’t pay more than you have to. What’s the cost per serving, and how many servings are in the product?  
  • Taste – Most of the choices in this guide are unflavored. For some, they may not taste good on their own. Still, they can be mixed with pretty much anything while having little impact on the taste. 

Always read and follow the label directions. 

Protein powders can be mixed with virtually any beverage. They can also be mixed with yogurt or oatmeal. 

You can bake with some of them but make sure you check the label first. You don’t want to bake with a product that does not specifically say it can be used for that purpose. 

Use a protein powder 1-2 times per day to help meet your daily protein requirements, and try to ingest protein every few hours. On training days, have one serving within 30 minutes after working out. 

It’s also smart to have a shake first thing in the morning every day. You’ve spent the last 7-10 hours sleeping, so when you wake up, your body needs to be replenished with macronutrients, especially protein. 

Using a protein powder without any artificial sweeteners is a great choice toward a clean, healthy approach to your daily nutrition. 

Our best overall protein powder without artificial sweeteners is NutraBio 100% Whey Protein Isolate Unflavored. It’s unflavored and contains 25g of whey isolate per serving. That’s all that’s in this product. It also features extreme full disclosure labeling. 

If you want an unflavored option you can bake with, Opportuniteas Grass Fed Whey Protein Powder Isolate contains 29.7g of protein, and that’s it. You can make any recipe you want and add in this protein. If you don’t like protein shakes, here you go! 

Finally, budget is a concern for many users. If that’s the case, Nutricost Whey Protein Concentrate is the way to go. It’s a 5lb container, it provides 25g of whey concentrate per serving, and that’s the only ingredient. Best of all, it has an amazing price point. 

As you can see, when it comes to protein powder without artificial sweeteners, there are some great choices!
