You don’t have to be a nutritionist or dietitian to understand the different types of whey protein. Once you scratch beneath the surface, it becomes clear that each type of whey protein has its unique offering, both for beginners and protein aficionados.
Whey protein concentrate (WPC)
As with all whey protein, concentrate is derived from the by-product whey of milk during cheese production. It’s the least processed form of whey and therefore retains a higher amount of beneficial compounds, such as minerals and nutrients. This protein-packed powerhouse is known for its comparatively high fat and lactose content, making it creamier and more flavourful than its counterparts.
Advantages
Rich in immune-boosting factors and beneficial nutrients, WPC often boasts a fuller, more natural flavour profile, perfect for those who prefer a tastier shake. It's also typically more affordable, providing excellent value for money.
Disadvantages
WPC’s slightly higher fat and lactose content can sometimes be a downside for those sensitive to dairy or lactose. Additionally, it generally offers a slightly lower protein percentage compared to whey protein isolate.
Whey protein isolate (WPI)
Distinguished by its pure, refined nature, whey protein isolate is additionally processed to remove more of the fat and lactose. This process results in a protein content that often exceeds 90%. Originating from the same cheese production process as WPC, the extra filtration steps make WPI a more concentrated protein source.
Advantages
WPI is appealing to those who seek a higher protein intake with minimal calories from fats and carbohydrates. Its low lactose level makes it a friendlier option for those with dairy sensitivities or lactose intolerance and its mild taste and smooth texture allow it to blend into the background of various foods and beverages.
Disadvantages
Its higher protein purity comes at a price, making WPI often more expensive than WPC. Some of the beneficial nutrients and immune-boosting compounds present in WPC are reduced as a result of the more intensive processing.
Whey protein hydrolysate (WPH)
Whey protein hydrolysate stands out as the ‘pre-digested’ form of whey protein. This involves breaking down the protein into smaller peptide chains, simulating the initial stage of digestion. This means when you consume WPH, your body has to do less work to assimilate and use the protein.
Advantages
The primary benefit of WPH is its rapid absorption rate, making it the fastest-acting among all whey protein forms. This is especially beneficial for moments when the body craves rapid nutrition. The hydrolysis process also reduces allergenic properties, making it a suitable option for those who might react to other forms of whey.
Disadvantages
The pre-digested nature of WPH can give it a bitter taste, making it less enjoyable as part of your daily routine. Its advanced processing also makes it the priciest among the three whey protein types.
