Our Packaging

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.

  • 23g protein per serving
  • Complete amino acid profile
  • Perfect night-time shake

Nutritional information may vary depending on flavour.

Taking much longer to be digested and used by the body, this is the perfect shake for getting a sustained supply of protein between meals and even while you sleep — always fuelling your training goals.1

It also includes a complete amino acid profile — these naturally occur in protein and help to build and repair new muscle,1 before, during, and after workouts — so you can wake up raring to go for your next session.

1. Protein contributes to the growth and maintenance of muscle mass.

When to take Slow-Release Casein?

It’s slow absorbing, so we recommend adding 1 large scoop (30g) to water or milk 30 minutes before bed— but it’s also ideal any time for a convenient way to get the protein you need.

What does Slow-Release Casein work well with?

While it’s important to get the protein you need, try with ZMA — which provides a unique blend of vitamins and minerals to promote overall health and wellbeing.

Do not exceed the stated recommended daily dose. This product is a food supplement and therefore should not be used as a substitute for a varied diet and a healthy lifestyle. Store in a cool dry place, out of the reach of young children.

    Late Night Nutrition
    4 out of 5 stars
    I have used Calcium Casseinate for a decade now, and love the way it makes me feel. Its a slow release protein that keeps me nutrified through the night, and the gains I get definitely increase when I use it. I have always used Myprotein's Casein because it is great value for money and perfect for for all serious trainers! Goes Well With: I mix it with a flavoured Whey concentrate in a 75% Casein 25% Whey blend

    Chocolate is the best!
    4 out of 5 stars
    The product took a lot of work to mix. On this occasion, I tried chocolate, which tasted better than vanilla. As for its efficacy, who knows? Goes Well With: Milk
