Informed Choice & Informed Protein: Certified Confidence

Informed Choice is a globally recognised quality assurance programme for sports nutrition. Through voluntary, random testing, it helps ensure products are manufactured to rigorous international standards.

Informed Protein certification goes a step further — independently verifying protein content and amino acid profile. Products are tested across multiple batches, with samples screened for heavy metals, pesticides, and other potential contaminants.

So when you see the Informed Choice and Informed Protein logos on our products, you can be confident they’re regularly tested for quality, purity, and consistency.

Whether you’re hitting your macros or just want something that feels like a treat, this is the protein shake that actually tastes like one.

Creamy milk chocolate flavour comes first, balanced by caramel sweetness and a subtle malty nougat flavour. The finish? Velvety, smooth, and indulgent. Rediscover the great taste of MARS®.
