Optimum Nutrition Protein Crunch


  • Awesome Flavours!
  • Unique Concept
  • Quality Protein Hit



Optimum Nutrition Protein Crunch puts a new spin on packaged protein. Rather than opting for the standard protein bar recipe, the team at Optimum Nutrition have created the ultimate Protein Crunch bar that is not only satisfyingly tasty, yet also delivers a 20 gram hit of high-quality protein, with a mere 221 Calories in the process (per bar for chocolate flavour).


If you are sick and tired of eating the same old mealy protein bars that pretty-well taste like packaged cardboard with a little flavouring thrown into the mix, it might be time to give Optimum Nutrition Protein Crunch a go.


   ON protein crunch bars


One of the most important requirements of a protein-based food product, or even a wholefood, is the quality of that protein. The quality is determined by the quantity and ratio of the essential amino acids that are contained within the protein molecule. A protein molecule is a complex three-dimensional structure made up of lots of individual amino acid units joined together.


You could use the chain analogy, wherein every link in the chain is an amino acid. Now, if you ball that chain up into one big pile, this is somewhat what a protein molecule looks like.


Once our digestion gets to work unfolding the chain and breaking apart some of the links into single, two or three link units, we can then absorb the amino acids and utilise them. The protein sources used in Optimum Nutrition Protein Crunch bars are whey protein isolate, whey protein concentrate and milk protein concentrate.


Whey Protein is generally regarded as one of the highest biological value protein sources1. It contains high quantities of essential amino acids, as well as the famed branched chain amino acids, providing you with foundational building blocks for muscle and soft tissues, such as tendons and ligaments.

Not only does Optimum Nutrition Protein Crunch deliver exceptional protein nutrition, they also taste great. If you feel like some extra indulgence—and have some calories up your sleeve—try chopping them into a few bite-sized chunks and drizzling melted dark chocolate over the top. Now refrigerate to harden the chocolate. What you end with is a protein and antioxidant hit worth saving calories for! 


If you are ready for something different and delectable, try Optimum Nutrition Protein Crunch.
