Independent UK market analysis reveals 3 in 4 protein product labels are misleading

Two flagship Myprotein products – Impact Whey Protein and Impact Whey Isolate – have won independent recognition in a significant milestone that reinforces the brand’s position as a leader in product quality and transparency.

This double recognition marks the first time any Myprotein products have achieved certification from Informed Protein, an independent certification programme run by global testing authority LGC. It verifies that products meet strict criteria around:

• True protein content – free from amino acid spiking and fillers
• Product purity – tested for contaminants and undeclared ingredients
• Manufacturing standards – produced in facilities that meet rigorous safety and quality protocols

The certification comes at a time when the sports nutrition industry is under increasing scrutiny for misleading labelling and inconsistent ingredient claims. A recent analysis by Informed Protein found that only 27% of protein powders tested actually contained the amount of protein stated on the label, with nearly three in four labels considered misleading. This highlights the scale of the problem and the urgent need for greater transparency and independent verification.

The Informed Protein certification represents a clear point of differentiation and a mark of quality assurance for both trade buyers and consumers. With this achievement, Myprotein becomes one of the first UK sports nutrition brands to secure this globally recognised accreditation.

While Impact Whey and Impact Whey Isolate are the first to be certified, Myprotein has confirmed plans to expand certification to additional SKUs over time, particularly across its core product ranges.

Neil Mistry, CEO, THG Nutrition said: “Securing Informed Protein certification reflects our commitment to the highest manufacturing standards. It’s a mark of quality and an independent reassurance for consumers that they’re getting exactly what’s on the label. As the category grows, third-party validation like this will only become more important for trust and differentiation, reassuring both consumers and trade buyers.”
