Impact Casein is our highly popular milk protein powder, designed to be slow absorbing to provide a sustained supply of protein between meals and even while you sleep.

This makes it the perfect choice for bedtime protein shakes, helping you to wake up raring to go, ready for your next session. It also includes a complete amino acid profile for a well-rounded formula.

We've gone through an exciting redesign, and as we step into a new era, you'll see fresh packaging in your orders. Change is a good thing. But change takes time. Especially when you make change responsibly.

Because we don't believe in wasting perfectly good packaging – that would go against our sustainability pledge you might get a mix of old and new designs inside your orders.

Rest assured, it's still the same consistently high-quality product, just as you'd expect. If you happen to receive classic packaging, know that your order is helping to reduce waste. And if you receive anything with a fresh look, you're one of the first, and we'd love to hear what you think.

Thank you for joining us on our journey to reduce our impact on the planet, while maximising our impact for our community.

What are the benefits of Slow-Release Casein?

Our Slow-Release Casein is packed with 23g of protein, making it ideal for helping grow and maintain important muscle.¹

Casein takes a long time to be digested and absorbed by the body, making it the best blend for a more sustained supply of protein throughout the day or night.

Who is Slow-Release Casein for?

Getting enough protein into your diet is super-important for anyone working towards a fitness goal. It’s especially ideal for those who prefer a night-time shake with a gradual release of protein.

As one of the most common sources of protein is meat, the fact that our Slow-Release Casein is suitable for vegetarians makes it perfect for getting a protein boost with minimal effort, whatever your lifestyle. Plus, our blend doesn’t have any ingredients containing gluten.

What does Slow-Release Casein taste like?

Our protein powders aren’t only created to offer great nutritionals, but to deliver on taste too. That's why we offer Slow-Release Casein in range of flavours to suit anyone, choose your favourite from the classics — Chocolate, Strawberry, and Vanilla.

Or, it comes in Unflavoured if you’d rather put your own twist on shakes and smoothies.
