Opportuniteas offers, in our opinion, the best protein powder without artificial sweeteners overall. The unflavored version is made of only two high quality ingredients: grass-fed whey isolate, and non-GMO sunflower lecithin for a bit of texture. However, if you want flavored powder, you can opt for one of the three flavors: chocolate, coffee, or vanilla.

The chocolate and vanilla flavors are sweetened with a bit of organic cane sugar. For some looking for protein powder without artificial sweeteners this may be an advantage, while some may find it a drawback. If you are in the latter category, we recommend you to go with the unflavored option, or the coffee variation which is not sweetened.

As far as mixing goes, it mixes very well with a shaker cup of a blender. Our suggestion is to add the unflavored powder to smoothies or recipes, and add the sweetener of your choice and in whichever quantity you see fit.

Pros

  • Very high protein content
  • Only two to five high quality ingredients, depending on the flavor you choose
  • Mixes very well

Cons

  • Not much flavor variety

People believe that plant based protein powders are not a complete source of protein. And while that is true with some products, it is not the case with Truvani's vegan protein powder. This vegan supplement gets its protein from a blend of three different sources: organic pea, organic pumpkin seed, and organic chia seed.

You can get the Truvani protein in four different flavors: banana cinnamon, chocolate, chocolate peanut butter, and vanilla. Depending on the flavor you choose, you are looking at five to seven ingredients, out of which three are the protein source. This is what we'd call a minimal ingredients list.

But let us have a better look at the quality of ingredients. We'll take the example of chocolate peanut butter flavor which has seven ingredients: organic pea protein concentrate, organic alkalized cocoa, organic peanut flour, organic vanilla powder, organic pumpkin seed concentrate, organic monk fruit extract, organic chia seed protein concentrate. As you can see, the ingredients are easy to read and the sweetening agent is organic monk fruit extract - a natural sweetener.

Regardless of the flavor you choose, Truvani is sure to please your taste buds and offer you a protein rich drink you can use pre or post workout.

Pros

  • Minimal  and only organic ingredients
  • Complete source of protein
  • Naturally sweetened with organic monk fruit extract

Cons

What is bad about artificial sweeteners?

Picture of a teaspoon inside of a sugar jar

A lot of people know that they should not be consuming artificial sweeteners but they don't really know the reason behind it - other than the fact that the word "artificial" is part of the name.

And we know that artificial anything is bad.

Anyway.

Here are some of the drawbacks of artificial sweeteners. Mind you, more studies are needed to make a clear correlation between artificial sweeteners and these effects:

  • Artificial sweeteners may increase appetite and promote weight gain (1)
  • Your brain may be confused into feeling hungry because, unlike sweet-tasting foods, artificial sweeteners don't have calories (2) (3)
  • Some studies point that there seem to be a link between artificially sweetened beverages and obesity (4) (5)
  • However, some studies report that artificial sweeteners may help with weight loss (6) (7)
  • Those who drink diet soda may have a 36% increased risk of metabolic syndrome (8)
  • In another study, it was found that in 4 out of 7 healthy individuals who had never consumed saccharin before the gut bacteria balance was disrupted (9)

And so on and so forth.

Healthline put together a great article in which they discuss at length the debate of whether artificial sweeteners are good or bad.

And here are the most common artificial sweeteners and the brands they are marketed under:

  • Aspartame - NutraSweet, Equal, Sugar Twin
  • Acesulfame potassium - Sunnet, Sweet One
  • Saccharin - Sweet'N Low, Sweet Twin, Necta Sweet
  • Sucralose - Splenda

What are the best alternatives to artificial sweeteners?

Before we find the best alternative, let's understand what artificial sweeteners are trying to achieve.

The idea behind artificial sweeteners is to have a sweetening agent that has no calories and resembles sugar as much as possible. Unfortunately, these also come with drawbacks.

Therefore, is there any sweetening agent that resembles sugar, has no calories, and is also not harmful to your body? Yes, and these are:

  • Stevia
  • Erythritol
  • Xylitol
  • Yacon syrup
  • Luo Han Guo or monk fruit

These are all recommended natural sweeteners which will not harm your body. If anything, some of these also have some beneficial effects.

For instance, xylitol appears to have some benefits in protecting against caries - study.

How to choose the best protein powder without artificial sweetener?

Protein shake without artificial sweeteners

So how do you choose a good protein powder without artificial sweeteners, aside from checking the ingredients list for artificial sweeteners - d'uh.

There are some other things you should be on the lookout for:

  • No added sugar
  • Protein to sugar ratio
  • Quality of ingredients

No added sugar

Artificial sweeteners are added to replace sugar. So, arguably, having added sugar in your protein powder is worse than having artificial sweeteners.

Whether you believe this to be true or not is a matter of preference.

However, in the context of choosing the best protein powder without artificial sweeteners, we recommend you to look for powders that are sweetened with natural sweeteners.

To recap, these are:

  • Stevia
  • Erythritol
  • Xylitol
  • Yacon syrup
  • Luo Han Guo or monk fruit

Protein to sugar and calorie ratio

Another important thing you have to keep in mind is the protein to sugar ratio.

Ideally, you will want a protein shake rich in protein with close to or no sugar whatsoever, and around 100-140 calories per 30g of powder. And as a rule of thumb, we would disregard most powders which have under 20g of protein per 30g.

There are a few small exceptions which have been added to the list above.

In our review we have taken care of sorting the powders by these requirements. Therefore, you can confidently shop for them knowing that we chose what we truly believe to be the best supplements.

Quality of ingredients

Ingredient quality is also something to keep in mind, unless you only care about getting your protein intake.

Some people say protein powders are meant to help you meet your protein requirements, therefore you shouldn't be fussy. Their taste and ingredients are an afterthought as long as you get your protein. And we do get that they have a point and, at the end of the day, to each his own.

As far as we are concerned, we like to choose powders that don't harm our health.

And we recommend you do the same.

Look for powders coming from grass-fed cows which have non-GMO, organic ingredients. If the ingredients list is too long or, perhaps, it is very difficult to pronounce some of the ingredients, you may be better off looking at another product.

How to take your protein powder?

Man making a protein shake

If you have decided to get your protein powder without artificial sweeteners, you may want to know what your intake should be, as well as when you should be supplementing with protein.

How much protein should you take?

The protein intake is highly dependent on your goals. Usually, people who supplement with protein shakes have two major goals:

  • Building muscle
  • Losing weight

Building muscle

Ever since bodybuilding got popular decades ago, people wanted to know what is the optimal protein intake to build muscle. Back in the day they didn't have scientific studies, so the concept was simple: eat as much as possible to get big.

Now, things are different thanks to science.

According to studies, to build muscle mass you should be consuming 0.73 to 1.1g of protein per pound of body weight, or 1.6 to 2.4g of protein per kilogram of body weight. You can read those studies yourself by going here and here.

However, building muscle is impossible without some form of resistance training. Therefore, the above studies only apply assuming you are lifting weights, doing calisthenics, or other forms of resistance training.

Losing weight

To lose weight, the amount of protein is not that important - as long as you consume your minimum requirements. Losing weight boils down to burning more calories than you are consuming throughout the day.

The same studies cited below have shown that…

During a weight loss period you should be consuming 0.36 to 0.73g of protein per pound of body weight, or 0.8 to 1.6g of protein per kilogram of body weight.

Remember that these are the minimum values and that it all depends on how many calories you burn.

How much protein should you take?

This is where we enter the realm of overthinking, if you ask us.

We agree that timing is important to optimize muscle protein synthesis. However, at the same time, we feel like the benefits are pretty minimal. So you can do it but we just want you to know that if you don't time your protein intake "just right" you will not be messing with your gains.

And again, this is a matter of goals.

Building muscle

With the preface above done, if you want to get the most benefit out of your protein supplement, then you should take it right after training. That or any other form of quick releasing protein.

Multiple studies have shown that getting your protein right after a workout increases your muscle protein synthesis, total muscle mass over time, increases your performance and strength, and lowers the risk of getting sore. (10) (11) (12) (13)

This applies to both men and women.

Losing weight

To lose weight optimally, you should still get your protein powder after the workout if you are working out.

However, if you are not working out, you should be drinking your protein shake in between meals. This will keep you satiated and prevent you from snacking.

Furthermore, if you choose a flavored protein shake or add your protein powder to a smoothie, it will also curb any cravings for sugar that you may have, further preventing snacking.

Our verdict

Choosing a good protein powder that is not artificially sweetened can be hard work, especially with all the clutter in the supplement industry.

However, you can still find outstanding products if you know what to look for.

We found the Opportuniteas Grass Fed Whey Isolate to be the best protein powder without artificial sweeteners on the market. It has a very high amount of protein, flavor variety, including unflavored, and is made of high quality and minimal ingredients.

But if this powder doesn't really suit your needs, there are other options better suited for you in the list above. Choose the one that you like best and shop with confidence, knowing that we've done the research for you.

Over to you.
