Quick answers

Is this right for you?

Who is it for?

Prozis Clear Whey Isolate is designed for anyone who finds milky shakes heavy, especially in hot weather or straight after training. Clear whey drinks like juice or squash, and because it is made from whey isolate it keeps the high protein and low fat of an isolate.

What can you expect?

A light, juice-style protein drink made from whey isolate that has been acid-treated so it mixes clear instead of milky. It is typically 75-90% protein with very little fat, and fruit flavours rather than dessert ones. Mix it with cold water and let the foam settle for a minute before drinking. With 81g of protein per 100g (around 20g per 25g serving), Prozis Clear Whey Isolate sits at the higher end for a clear whey product.

What else do you need to know?

Prozis Clear Whey Isolate is a clear whey protein powder made by Prozis. It comes in 500g sizes.
