Best Meal Replacement & Protein Shakes Without Artificial Sweeteners (2021)

The fear to the negative effects of sugar gave raise to the era of artificial sweeteners. Ingredients like acesulfame-k, aspartame or sucralose can be found anywhere. This is particularly true for protein powders, which try to provide you with the most amount of protein without too many calories. Therefore, finding the best meal replacements and protein shakes without artificial sweeteners is not easy.

As such, I have compiled a list of what I consider the best meal replacements and protein powders with no sucralose or aspartame or similar. Instead, the shakes listed below use natural sweeteners like monk fruit, stevia extract, honey or just sugar (cane or coconut). Healthier alternatives that can help you improve your gut health and reduce side effects.

Before diving into the list, I want to let you know that it’s divided in two parts:

  • In the first, I mention my favourite meal replacements without artificial sweeteners. Ideal to replace your breakfast or lunch with.
  • In the second, I discuss protein powders with no artificial sweeteners that I’ve tried and enjoy.

Best Meal Replacement Powders Without Artificial Sweeteners

1. Ample V

Editor’s Choice

best soy free meal replacement shake
  1. Sweetened with honey, stevia and monk fruit
  2. 3 formulas to choose from: Plant based, whey based and keto
  3. No artificial sweeteners, no artificial additives, soy-free, GMO free and gluten free
  4. Contains digestive enzymes, probiotics and prebiotics to help your gut
  1. Lacks some vitamins and minerals
  2. Premium pricing

Ample shakes are some of my favourite meal replacement shakes. They have a superb blend of quality and great tasting shakes that I really enjoy.

Another factor that makes me like Ample is the fact that they don’t have any synthetic additives and are free of artificial sweeteners.

They offer real food based shakes, that are usually low on carbs and high in fats. They even have a ketogenic shake for those looking to lose some weight. However, I think that for most the Plant-based and/or Original will be the better choice.

All three of them have active ingredients like probiotics and digestive enzymes that help your gut microbioma.

Plus, because they are powders without sucralose or aspartame, you will find Ample meals really easy to digest.

2. HLTH Complete Meal

Best Low Carb

  1. 2 lovely shakes: Chocolate Macadamia and Vanilla
  2. No artificial sweeteners; sweetened with monk fruit and stevia
  3. Low carb high protein formula — good for weight loss
  4. Super rich in nutrients (50% of DV for vitamins and minerals)
  5. Includes probiotics, digestive enzymes
  1. Only two flavours
  2. Uses stevia leaf extract

This is another fabulous brand that offers real food based shakes without any artificial additives or sweeteners. In fact, HLTH Complete meal is one of the healthiest and most pleasant drinks you can get.

Unfortunately, they do use stevia leaf extract, together with monk fruit; so if you are looking for a stevia free shake, this won’t be for you. Personally, I didn’t notice any strong stevia taste, like some other shakes do.

Nutritionally, HLTH is a low carb (only 4g!) shakes with tons of protein (27g). Engineered by Dr. Ben Bikman, the goal is to provide you with a science backed meal that makes you feel good. For that, they also add probiotics and digestive enzymes, and in my experience it’s easier to drink than other meal replacement shakes.

When it comes to taste, I have little complaints too. Chocolate Macadamia (my favourite) is sublime; sweet and flavourful like a chocolate milkshake. I just wish it was slightly thicker!

Best RTD

  2. Vegan, hypoallergenic
  3. Best texture and great taste
  4. Optimal to consume on the go
  5. Sweetened with coconut sugar

Only What You Need or OWYN is the ideal dairy free shake to take it with you anywhere. It contains no artificial sweeteners, no gluten, no soy; while providing you with all the nutrients your body needs per bottle.

Each bottle comes with 300kcal, 20g of protein and no stevia, no sucralose nor any aspartame. Unlike most ready-to-drink products out there, OWYN’s won’t upset your stomach after drinking it. Unfortunately, it’s not as rich in fibre as other alternatives, and does not come with probiotics or digestive enzymes.

Nonetheless, you can buy it on Amazon with free shipping and enjoy one of the two lovely flavours that they offer: Chai and Chocolate. While, I do love Chocolate, it is currently more expensive than Chai. Thus, maybe you should buy Chai this time.

Understanding Artificial Sweeteners

Sweeteners are sugar substitutes that give food a sweet taste without adding as many calories. In fact, many provide with no-calories and do not cause any effect in blood glucose like sugar does. These sweeteners can be natural (derived from plants) or synthetically created. The latter is much more commonly used in the industry, particularly in sweets, low-calorie sodas etc.

Types of Artificial Sweeteners Found on Protein Powders

Another common area where you will find artificial sweeteners is protein powders and other nutritional supplements. Because they can add sweetness without adding calories; they are widely used to create blends with less calories (higher percentage of protein).

These are some of the most common culprits that you can find:

  • Acesulfame K or acesulfame potassium. A very common sweetener, 200 times sweeter than sucrose (sugar) that has a slightly bitter taste. Thus, it’s often found in conjunction with other sweeteners (aspartame) with synergistic effects. There are concerns over the possible carcinogenic effects of ace-k; but these have been refuted by the FDA and ESFA.
  • Aspartame. Another popular sweetener in protein powders, often paired with ace-k. It is 200 as sweet as sugar, and it’s been approved by the FDA since 1981. There are some health hazards for those with phenylketonuria due to the presence of phenylalanine. Despite being some of the most rigorously studied sweeteners, there is public concern about carcinogenic and neurological effects of aspartame.
  • Sucralose. This synthetic sweetener is 3x as sweet as aspartame, and it’s considered safe by most health agencies. It is even safe for diabetics, since it does not cause any alterations in blood glucose. Most of the sucralose ingested is not absorbed and only 2-8% is metabolized. However, there are some increasing concerns of the effect of sucralose, particularly after being heated.

To summarize, most of the artificial sweeteners used in protein powders are considered safe to very safe. However, there’s a popular belief that the adverse effects have not been properly studied in humans and might cause some long term negative effects.

Popular Alternatives to Artificial Sweeteners

Therefore, many have started looking for alternatives and protein powders with no artificial sweeteners. While the industry is still dominated by synthetic options, there are few other ingredients:

  • Stevia. This is a tricky one, since it can also be highly processed. However, it is usually the #1 choice for manufacturers. The plant stevia contains steviol glycosides that are 30-150 times as sweet as sugar. There are a few concerns about stevia, but also about how it affects the flavour. That’s why I included some protein powders without artificial sweeteners or stevia (Owyn).
  • Monk fruit. Another natural sweetener that is 300 times as sweet as sugar. While in the US is considered generally safe by the FDA, its use is not approved in Europe. Thus, most European powders will include stevia or sugar instead.
  • Honey. Honey is a caloric sweetener, unlike the previous two, since it contains fructose and glucose. However, it is usually packed with other nutrients (mostly vitamins and minerals), which might have benefit health effects.
  • Coconut sugar. Instead of using white refined sugar, some brands will go for coconut sugar. Nutritionally, it’s very similar to it though; with just some naturally occurring nutrients that are not destroyed in the refining process.

Besides the above mentioned, you might also find coconut sugar, rice sugar, cane sugar or even normal sugar in protein powders and meal replacements that contain no artificial sweeteners.

Sugar or Natural Sweeteners, What is Best in Protein Powders?

There is no simple answer to this question, and it will largely come to what your preferences are. In the United States, for instance, food is blasted with hidden sugars and consuming more than the daily recommended is not unusual. Therefore, for those naturally sweetened protein powders might make sense.

Another factor to look at are calories. If you are looking for diet drinks without aspartame, but don’t want to add calories naturally sweetened drinks (like Complete Protein Powder) will be your best solution. Otherwise, you can still enjoy meal shakes that are low in sugar like Ample O.

If we considered taste, then you might want to avoid stevia (not always but for some might taste too bitter) or look for stevia extract. Honey or coconut sugar can also be good alternatives.

Factors to Consider Before Buying the Best Artificial Sweetener Free Shakes

So, you are ready to purchase your protein powder free of sucralose. Or so you think. Make sure you take these factors into consideration before buying the best powders without artificial sweeteners:

  • Vegan or vegetarian. Are you looking for a fully plant-based shake or you are happy with a whey protein powder with no artificial sweetener?
  • Naturally sweetened or sugar. As mentioned in the previous section, it’s your choice to opt for a non-caloric sweetener like stevia, monk fruit or something more traditional like honey or coconut sugar.
  • Budget. Most of the best powders without artificial sweeteners mentioned in the list are fairly affordable. However, you will have some at less than $1 per serving, and others that might cost you over $2.
  • Protein shake or meal replacement shake. You might have realized that I have not used both terms as synonyms. Meal replacement shakes are better suited to replace meals, as they are more balanced and nutritionally complete. Protein shakes, on the other hand, they are mostly protein and don’t have essential ingredients like omega-3 or micronutrients, often.

Conclusion: The Best Meal Replacement Shakes and Protein Powder without Artificial Sweeteners are

… Ample O and Four Sigmatic Cacao. Two great shakes that will provide you high quality nutrients without artificial additives. They have a lovely taste and texture, on top of that.

However, if you are looking for stevia free alternatives I recommend you looking at OWYN. For a more budget option, Vegan Blend for my protein might be your choice.

Have a good look to my top picks and enjoy!
