If you search the City Health web site for whey protein you'll find over a hundred types with many brands and even more flavours. So what's the difference? There's different types of protein powder depending on your needs and goals. This article should help to explain the differences. Note some of the products listed are actually blends of different proteins so make sure you read the product description for full details.

Whey Protein Concentrate (WPC)

WPC is by far the most popular class of protein supplement that we sell. Usually inexpensive and equally good for the average gym goer and those who want to supplement their diet with protein. Typically slightly higher in fat and carbs than WPI but usually only a couple of grams of fat per serve. Many popular whey proteins are a blend of WPC and WPI.

Whey Protein Isolate (WPI)

WPI is our next most popular form of protein powder. WPI is high in protein, low in fat and low in carbohydrate. Quick absorbing and perfect for those on a low carb diet. Most WPI is low in sugar and is popular for post workout shakes. Whey Protein Isolate is also low in lactose if you're lactose intolerant.

Mass Gainers and Weight Gainers

While most protein supplements are relatively low in carbohydrates the exception is mass gainers (also known as weight gainers). For bodybuilders trying to get big in the gym a mass gainer contains a solid hit of carbohydrate in each serve.

Casein Protein

If you're after a protein that breaks down slowly or to take before bed then casein is what you're looking for. Casein can take up to 7 hours to break down so it's great to help stay full during the day or during sleep.

Vegetable Proteins

While not particularly popular with bodybuilders, for those vegetarians there's a range of non-dairy proteins available on the market. The most popular of these are soy proteins but other options include pea protein and rice protein.

Protein Powders with Fat Burners/Thermogenics

There's an increasing range of whey protein with fat burners now available on the market. These combine whey protein isolate and/or whey protein concentrate with thermogenic ingredients such as green tea, caffeine, carnitine and others. These can be useful for fat loss and diets where you don't want to take a separate diet pill. Generally contain stimulants so they aren't suitable for taking before bed.
