October 16, 2025 •

4 min read

Despite being a popular, high-protein option for many, Premier Protein shakes contain artificial sweeteners and controversial additives that may cause digestive distress and long-term health concerns for some individuals. The answer to whether is Premier Protein actually healthy? depends on your nutritional philosophy and tolerance for processed ingredients.

Quick Summary

An evaluation of Premier Protein reveals a solid macronutrient profile with high protein and low sugar, but relies on artificial ingredients. While convenient for boosting protein, consumers should weigh the benefits against potential health concerns from additives and processing.

Key Points

High Protein, Low Sugar: Provides 30g of protein with only 1g of sugar, making it effective for boosting protein intake and managing macronutrients.
Artificial Sweeteners and Additives: The shakes use sucralose and acesulfame potassium, which are linked to potential gut microbiome issues and inflammation.
Digestive Concerns: Contains whey protein concentrate and additives like carrageenan, which can cause bloating and gas, especially for those with lactose sensitivity.
Convenience vs. Whole Foods: Premier Protein offers convenience, but whole foods provide broader, more natural nutritional benefits and fiber that processed shakes lack.
Not Third-Party Certified: The brand lacks robust third-party testing for purity, which can be a concern for some consumers, particularly competitive athletes.
Shakes vs. Powders: Some Premier Protein powders contain more natural sweeteners like stevia and monk fruit, offering a slightly cleaner alternative to the pre-made shakes.

What is Premier Protein?

Premier Protein is a widely available brand known for its ready-to-drink shakes and protein powders. The products are marketed as a convenient way to boost protein intake, particularly for those on low-carb diets or seeking muscle recovery support. A typical shake offers a substantial 30 grams of protein, a small amount of sugar (often 1 gram), and a good dose of vitamins and minerals, all for around 160 calories. The protein itself is a blend of whey protein concentrate and milk protein concentrate.

The Nutritional Pros: What Premier Protein Gets Right

Premier Protein provides some clear benefits, especially for individuals with specific dietary goals. The product's macronutrient profile is one of its strongest selling points.

High Protein Content: Each shake or serving of powder delivers a robust 30 grams of high-quality, complete protein, containing all essential amino acids. This is crucial for muscle repair, growth, and satiety, which can assist with weight management by helping you feel full for longer.
Low Sugar and Carbs: With typically just 1 gram of sugar and low carbohydrate content per serving, Premier Protein is a popular choice for those following keto or other low-carb dietary plans.
Fortified with Vitamins and Minerals: The shakes are fortified with numerous essential nutrients, including significant percentages of the daily values for calcium, magnesium, and various B vitamins. This can help fill potential nutrient gaps in a diet.
Convenience: For people with busy schedules, Premier Protein offers a quick, portable, and easy source of protein that can be consumed on the go.

The Nutritional Cons: Why It's Not a 'Health Food'

Despite its appealing macro breakdown, a closer look at the ingredient list reveals some significant drawbacks that categorize Premier Protein as a highly processed food.

Artificial Sweeteners: The shakes contain sucralose (Splenda) and acesulfame potassium (Ace-K). While approved by the FDA, research suggests sucralose may impact gut health, blood glucose, and insulin levels for some, and can potentially increase inflammation. Ace-K has also raised long-term health questions in animal studies.
Controversial Additives: The inclusion of carrageenan as a thickener is a point of contention. Derived from seaweed, some studies have linked it to inflammation, digestive issues like bloating and IBS, and intestinal damage, though the FDA deems it generally safe. The products also use cellulose gel and cellulose gum, often sourced from wood pulp.
Whey Concentrate and Lactose: The use of whey concentrate, rather than whey isolate, means the product contains higher levels of lactose. For the estimated two-thirds of adults with lactose sensitivity, this can lead to uncomfortable digestive side effects like gas and bloating.
Ultra-Processed Nature: As an ultra-processed food, a Premier Protein shake lacks the diverse nutrients, fiber, and beneficial compounds found in whole food sources. Over-reliance on such products, to the exclusion of whole foods, can lead to less favorable health outcomes.

Premier Protein vs. Whole Food vs. 'Cleaner' Alternatives

Making an informed decision means understanding how Premier Protein compares to other options. This table highlights some key differences.


Feature	Premier Protein Shake	Whole Food (e.g., Greek Yogurt + Nuts)	'Cleaner' Alternative (e.g., OWYN Shake)
Protein Source	Milk protein concentrate, calcium caseinate, whey protein concentrate	Dairy protein, plant protein	Pea, pumpkin seed protein
Processing Level	Ultra-processed, includes additives	Minimal processing	Processed, but often with fewer additives
Sweeteners	Sucralose, Acesulfame Potassium	Natural sugars, no added sweeteners	Monk fruit extract, cane sugar (varies)
Fiber Content	Low (3g)	High (variable)	Moderate (3-6g)
Digestive Issues	Potential for GI issues due to lactose, additives	Generally well-tolerated (unless lactose intolerant)	Fewer potential GI issues, often lactose-free
Micronutrients	Fortified (vitamins, minerals)	Naturally occurring (vitamins, minerals, antioxidants)	Variable, often fortified
Price	Affordable and convenient	Variable	Can be more expensive

Is Premier Protein Right for Your Diet?

Ultimately, the healthiness of Premier Protein depends on how it fits into your overall diet and lifestyle. For someone who is generally healthy and using it occasionally as a quick, post-workout protein boost, the potential drawbacks may be minimal. It can help meet daily protein goals for those struggling to get enough from whole foods. However, it is not a suitable meal replacement or a staple for a truly healthy diet. Individuals with sensitivities or those who prioritize minimally processed, whole foods should consider alternatives.

Conclusion

In conclusion, while Premier Protein offers a high-protein, low-sugar solution in a convenient format, its reliance on artificial sweeteners, processed ingredients, and potential for causing digestive issues makes it a suboptimal choice for consistent, long-term health. The pre-made shakes, in particular, come with a higher degree of processing and more controversial additives compared to the powder. A truly healthy diet is based on whole, minimally processed foods, and while supplements can have their place, they should not replace the nutritional diversity that comes from eating a wide variety of whole food sources. Those seeking a cleaner protein boost can explore alternatives or prioritize whole food protein sources like Greek yogurt, eggs, or plant-based options. For the health-conscious consumer, the convenience of Premier Protein comes with a trade-off in ingredient quality.

Frequently Asked Questions

Stomach issues like bloating, gas, and discomfort can arise from several ingredients in the shakes. The use of whey protein concentrate, which contains higher lactose levels, is a common culprit for those with lactose sensitivity. Additionally, artificial sweeteners like sucralose and thickeners like carrageenan can trigger gastrointestinal distress in some individuals.

While the shakes contain a solid amount of protein and some vitamins, they are not a complete meal replacement. They lack the complex carbohydrates, healthy fats, and diverse nutrients found in a balanced meal. They are best used as a snack, a supplement, or a post-workout drink rather than a regular substitute for whole food meals.

Premier Protein shakes contain sucralose and acesulfame potassium, which are generally considered safe by the FDA. However, some research has raised questions about their potential effects on the gut microbiome, metabolism, and long-term health, particularly with high consumption. Personal tolerance and dietary philosophy are key factors in deciding whether to consume them.

Premier Protein and Fairlife shakes have similar macros (high protein, low sugar), but differ in ingredients. Fairlife uses ultra-filtered, lactose-free milk protein, which may be easier on the stomach for those with lactose intolerance. However, Fairlife can still contain some of the same artificial sweeteners and thickeners found in Premier Protein.

For weight loss, Premier Protein can be a useful tool due to its high protein and low sugar content, which helps increase satiety and reduce cravings. However, long-term, sustainable weight loss is best achieved through a balanced diet of whole foods, not relying heavily on processed supplements.

Healthier, less processed alternatives include protein from whole food sources like Greek yogurt, eggs, or lean meat. For supplements, brands like OWYN (plant-based) or those that use natural sweeteners like stevia and monk fruit are often considered cleaner options.

Yes, there can be a difference. Some Premier Protein powders (e.g., Vanilla Milkshake 100% Whey Powder) are sweetened with natural options like stevia and monk fruit, lacking some of the controversial artificial sweeteners and additives found in the ready-to-drink shakes.
