How We Ranked 

There are a few criteria that we consider before recommending any product.

The quality is, of course, at the forefront of our decision to include any product in our reviews. This could mean we choose supplements from certain brands, although we do consider quality options from newer or less-known companies as well. 

Keep in mind, products within the same category can and often do vary whether just slightly or enough to where someone would choose one over the other. It all depends.

But you can rest assured that any of the protein supplements in this list is going to offer a quality source of protein and minimal unnecessary ingredients. 

A few key criteria for our picks.

Ingredients/what’s in it?

Let’s talk about the ingredients you’ll find in these protein powders. 

Protein

We featured protein powders that are animal and plant-based. Whether one is better than the other, well, we won’t get into that because it’s entirely preference-based due to factors such as lifestyle and taste.

You can check out our protein reviews if you really want to learn about and compare the differences between animal and plant-based protein.

Although we’ll be honest, it doesn’t matter as long as you’re getting enough of the essential amino acids throughout the day and ideally, around training times for maximum effect. 

But to give you a brief explanation about whey isolate and concentrate and plant-based options, isolate goes through an additional filtration process than does concentrate. 

This rids a lot of the fat, carbs, and lactose from a protein formula. Isolate is often preferred by those who usually experience stomach discomfort. But concentrate is a quality source of protein as well and cheaper too.

Then you have the plant-based or vegan protein that may contain one or more protein sources from foods like pea, brown rice, chia, and more. 

Both animal and plant based are great choices for filling in protein needs.

Use our protein calculator to find your ideal daily intake for your goals and to also learn more about the importance of protein. 

Sweeteners 

While there are different forms of natural sweeteners, stevia, monk fruit, erythritol, and a variation of sugar are typically the most commonly used. 

Stevia and monk fruit are both nonnutritive sweeteners so there are little to no calories. However, both are also much sweeter than sugar, with monk fruit being 150-200x sweeter and stevia being 200-300x sweeter.

Sometimes these ingredients are used alone and many times, stevia and monk fruit are combined. 

Stevia in supplements, food products, and on its own is very refined because the leaf in its most natural state isn’t considered safe. This filtered form of stevia contains Rebaudioside A (Reb A) which is a glycoside responsible for the sweetness. 

Monk fruit is less refined but is sometimes is combined with dextrose although this is not the case with any of the protein products that you’ll find here. 

But one big drawback of certain natural sugar alternatives such as stevia and monk fruit is that some people simply don’t care for the taste. In that case, maybe real coconut sugar or no sweetener at all is preferred. 

It just comes down to preference ultimately. 

Other ingredients

This varies from product to product. Typically though, and this varies as well – many protein powders with no artificial sweeteners contain natural ingredients including natural flavors and coloring, superfood blends, and sunflower lecithin – which helps with the texture and consistency. 

Other than that, we tried to keep certain ingredients out. 

Overall value

We consider a good value to consist of these three main factors.

  • Quality of ingredients
  • Amount of servings for the price
  • Company reputation/history

How Should I Pick A Good Protein Powder

Consider the details below.

  • Ingredients – the ingredients should include a quality source of protein/s and if possible, minimal additional ingredients or ingredients that contribute something related to health or performance. We included many options that are very simple with one or just a few ingredients. But there also others with several ingredients, but that, again, are useful and not harmful. 
  • Brand reputation – all of the products on our list are from reputable brands and we’re confident in that. We chose the best protein powder products on the market that offered what we were looking for. 
  • Value – a good value offers a respectable amount of the key ingredient/s with an appropriate number of servings for a price that reflects what the product offers. 
  • Key Ingredients content – the key ingredients are protein and natural sweetener. Our picks all provide at least 20g per serving minimum and use common and proven safe natural sweeteners. 
  • Convenience factor – it’s important to keep in mind that some of the protein powders in this review are flavored and some are not. Typically, unflavored options are best included with other ingredients to be more palatable. Consequently, if you want to simply shake and go without the extra steps, a flavored option is your best bet. Some protein powders may require extra mixing or shaking due to certain ingredients or lack thereof (not necessarily a bad thing) and this could be an inconvenience for some. But the overall quality of the product may be more important for others. 

How Much Protein Should I Have Per Day?

We’ve talked about this numerous times in past articles and you can check the protein calculator link under the “ingredients/what’s in it” section for more information on optimal protein dosing. 

This is obviously going to vary from individual to individual based on personal stats (gender, age, weight, height) and goals. 

But to give you a general idea, the widely accepted range for protein intake is 0.7–1 gram per pound (1.6–2.4 grams per kg) of body weight.

It’s not uncommon for people to have to tweak their protein intake depending on their goals and health. But one thing for certain is that if you want to build muscle and strength through resistance training, you need sufficient protein for the repair and building process. 

This doesn’t mean to eat all of your calories in protein, but you should aim for the upper end if you train hard. 

Are Artificial Sweeteners Safe? 

Common artificial sweeteners such as sucralose, acesulfame potassium, aspartame, saccharins, and neotame are approved by the FDA for use in certain food items with some exceptions such as in meat and poultry (1).

The American Heart Association (AHA) and the American Diabetes Association (ADA) also approve of certain artificial sweeteners as a replacement for sugar.

Artificial sweeteners can help to lower caloric intake, thereby contributing to a reduced risk of obesity, diabetes, heart disease, etc.

Does that mean they’re safe though?

The short answer is that it seems they’re mostly safe for most people, at least in the short and mid-term. However, they are still artificial substances. Moderation is going to be key as with anything and that even includes natural sweeteners such as stevia and sugar, of course (1). 

But these sweeteners can certainly help with weight loss and disease management as far as caloric intake is concerned..

Recap

We’re happy with our picks and we hope you are too. As of right now, these might just be the best protein powders without artificial sweeteners.

Each one has something unique to offer too and now it’s up to you to decide which is best for you. Whether you exercise daily and want to ensure you meet your recommended intake or whether you want a quality option to include in your daily health regime, you have ten that meet the criteria.
