Verifying the 30g Protein Claim: What the Label Says
On the surface, the answer seems straightforward. Premier Protein's classic ready-to-drink shakes and protein powders clearly state "30g Protein" on the label and in product descriptions. The company sources this protein from a proprietary blend of milk protein concentrate and calcium caseinate for its shakes, and a whey protein concentrate and isolate blend for its powders. This combination of fast- and slow-digesting proteins is designed to support muscle fueling over a longer period. So, based on the manufacturer's own nutritional information, the claim is affirmed.
The 2017 Class-Action Lawsuit Explained
While the current label affirms the 30g claim, Premier Protein's history includes a significant controversy. In 2017, a class-action lawsuit was filed against Premier Nutrition Corporation, the maker of Premier Protein products. The lawsuit alleged false advertising, claiming that independent testing showed the protein shakes actually contained less protein than the advertised amount—reportedly between 2 and 5 grams less per serving.
This legal challenge concluded with a $9 million settlement in 2018, which was granted final approval in early 2019. While a settlement doesn't prove guilt, it does raise valid questions about the accuracy of labeling at that time. It also highlights the importance of third-party verification in an industry where labeling accuracy can be inconsistent.
The Importance of Third-Party Testing
This past lawsuit brings to light a key consideration for consumers: the absence of third-party testing. Premier Protein openly acknowledges that its products are not third-party tested. In the dietary supplement industry, this testing is a voluntary process where independent labs verify the product's purity and label accuracy. While it's not a requirement, third-party testing offers an extra layer of reassurance for consumers, especially competitive athletes concerned about banned substances.
However, a recent (2024) review by the athletic performance and nutrition site BarBend included independent lab testing of Premier Protein powder. The review noted that the product scored well for label accuracy, landing in the top 10% of products tested and earning an "A" grade for this metric. This offers some reassurance that, at least for the powder tested, the company's stated protein content was largely accurate.
How Does Premier Protein's Blend Compare to Others?
To fully evaluate Premier Protein, it's helpful to compare its protein blend and nutritional profile with competitors. Many protein drinks use either whey (fast-digesting) or casein (slow-digesting) protein exclusively. Premier's use of both milk protein concentrate and calcium caseinate provides a more sustained release of amino acids, which is a consideration for different fitness goals.
Common Protein Sources and Digestion Rates:
- Whey Protein: Digests quickly, making it ideal for immediate post-workout recovery to kickstart muscle protein synthesis.
- Casein Protein: Digests slowly, providing a steady stream of amino acids over several hours, which can help prevent muscle breakdown.
- Premier Protein Blend: Combines both whey and casein, aiming for a balance of quick recovery and prolonged muscle feeding.

| Calories | ~160 | ~150 | ~120 |
| Sugar | 1g | 1g | 1g |
| Carbohydrates | 3-5g | 2-3g | 3-4g |
| Vitamins & Minerals | 24 | ~3 | 23 |
| Protein Source | Milk Protein Concentrate, Calcium Caseinate | Whey Protein Isolate & Concentrate | Milk Protein Concentrate, Calcium Caseinate |
The Verdict: Do Premier Protein Shakes Measure Up?
Based on current labeling and recent independent testing of the powder, Premier Protein shakes and powders do appear to contain the advertised 30g of protein per serving. The company uses a blend of fast- and slow-digesting milk proteins, which offers a robust nutritional profile for muscle support. However, the past class-action lawsuit serves as a reminder that labeling accuracy has been questioned in the past. While the recent third-party testing conducted by BarBend on the powder yielded positive results for label accuracy, the brand does not consistently use third-party testing across its product line, which is a factor for some consumers. Ultimately, for those seeking a convenient, high-protein drink, Premier Protein delivers the promised protein content, but consumers should remain aware of its history and the lack of consistent independent verification.

Conclusion
In summary, the claim that Premier Protein shakes contain 30g of protein is currently supported by the product's nutritional information and, in the case of the protein powder, by at least one independent lab test. While a past lawsuit highlighted discrepancies in protein content, the issue was settled, and more recent data suggests improved label accuracy, especially for the powder. The shakes' protein blend of milk concentrate and casein, along with low sugar and high vitamin content, provides a balanced option for muscle recovery and daily nutrition. For consumers prioritizing independent verification, it's worth noting the brand does not universally use third-party testing.
