WHEY PROTEIN ISOLATE VS CONCENTRATES
Whey Protein Isolate vs Concentrates Where does it all come from, anyway? Proteins start its life off as milk and milk contains 2 Proteins (Whey & Casein). The whey can be separated from the casein and this happens naturally when dairy producers make cheese.
When it comes to making Whey protein powder, things moved way beyond milk and cheese. The liquid is filtered away, creating whey protein. The powder will contain a little fat and some carbohydrates (as like lactose), and a lot of protein (but check the percentages carefully to see what’s your guess you’re getting for your money).
The various types of whey protein powder and processed differently, which is why whey isolate is lower in lactose (milk sugar ‘s), carbohydrates, and fats we compare to whey concentrate.
The most popular types of whey protein are whey concentrate (WPC) and whey isolate (WPI). Which should you choose? Or should you get both and use them at different times of day? Let’s have a look.
WHEY PROTEIN CONCENTRATE.
Whey protein concentrate is the most common and popular type of whey protein powder and is produced when milk is filtered, and the whey protein dried. It usually contains around 80% protein, a small amount of fat, and some carbs.
The carb and fats aren’t high so if you need to get really nerdy with your numbers, the carbs and fats in a typical whey concentrate won’t mess with your macros.
Typical nutritional values of Pure Whey per 30g serving – 122 kcals, 24.2g protein, 2g fat, 1.5g carbs
Benefits: high protein, low carbs, low fat, good absorption, a complete protein, solid source of amino acids. Usually comes in a huge range of flavors (we have 18 in our Pure Whey Protein™ range) and is cost-effective and widely available.
Best for: topping up your protein numbers, pre- or post-workout nutrition, for using in smoothies or homemade shakes, or for making your own mass-gainers. Also great as a mix-in.
WHEY PROTEIN ISOLATE.
Whey protein isolate has been filtered further than whey concentrate, and has more of the fats and lactose (carbs) removed.
It therefore has a higher protein percentage and is absorbed more quickly than whey concentrate.
Because it’s low in lactose, it can be beneficial for people who have trouble with dairy products.
Typical nutritional values of Pure Whey Isolate 97 per 30g serving – 112 kcals, 29.3g protein, 0.09g fat, 0g carbs
Benefits: extremely low in carbs and fats, high in protein, low in lactose (Think Lactose Intolerance)and is absorbed quickly.
Best for: Post-workout nutrition, when you might want a source of protein which will digest easily without any significant fat to slow absorption.
- Also note, Whey isolates elicit more of an insulin response than whey concentrate protein powders.
Whey protein is considered a “complete protein”, containing all nine of the essential amino acids. But it’s still important to get the best quality protein you can. Luckily, good quality whey concentrates and whey isolates can be very cost-effective these days.
Even if your budget is tight, you don’t need to get protein powders which mix horribly, taste bad and contain un-named fillers. Look for a whey protein with a high percentage of protein per serving (like our Pure Whey Protein™ which has 80% or our Isolate which has 97%), with minimal extra ingredients (the label information should be clear) and no unnecessary fillers.
WHICH IS BEST FOR YOU?
Whichever you choose whey protein concentrate or whey isolate, both offer high-quality muscle building immune system boosting benefits and recovery from intense workouts. Both delivery a high amount of protein per serving and offer great value. If you are lactose intolerant, or if you want a more filtered whey product, one of our whey isolates is what we’d suggest.
