                     How to Differentiate Between Whey Protein, Whey Pr
otein Isolate and Hydro Whey Protein
• Whey Concentrate: It is formed when liquid whey undergoes microfiltration. It 
consists of 70-80% protein and is cheaper compared to the other types. 
• Whey Isolate: It is formed when whey concentrate undergoes further processing. 
It has 90% protein. It is costlier than concentrate. It has relatively lesser amounts 
of fats and sugar in it than concentrate. 
• Whey Hydrolysate: When the isolate is processed, then whey hydrolysate is 
formed. This is the costliest type since it is highly processed and in pre-digested 
form. It is easy for the body to absorb.
All the three are available as supplements in the market. Whey isolate or 
hydrolysate will have a higher protein content than concentrate. If you buy a 
product, always prefer them over concentrate. Do check for the other ingredients as 
well – do they add fillers, and other additives? Then avoid the product. 
Some harmful ingredients in 
whey proteins are:
• Artificial Flavours: They are known to be very harmful for health and it is 
better to avoid brands that use them. 
• Thickeners and Gums: Xanthum gum (INS 415), anti-foaming and anti-caking 
agents are best avoided. 
• Artificial Sweeteners: Ingredients such as Saccharin, Sucralose and 
NutraSweet can have create side effects like headaches, digestive issues, etc. 
• Fillers: They are used to increase the weight of the product and should be 
avoided. 
• Refined Sugar: It is best to avoid supplements containing refined sugar as it 
is said to be harmful and too much use of it can cause issues.
Always check if the product has been tested and certified by a valid 
third party. You should read about the processing, the source, etc. 
There are many fake products in the market and you should always 
check for the authenticity of the product before buying. The amount of 
supplement you have each day depends on your requirements. Consult 
a nutritionist to know more.
