Whey Isolate vs Whey Concentrate
May 3, 2016
There are so many protein powders out there, all with shiny labels, unbelievable promises and a wide range of tasty flavors. Do you rely on your gym buddy? On marketing claims? How do you choose the right one for you?
Let the Protein Battle Begin
Which Protein Packs the best Punch
Protein is a must when it comes to a well-balanced diet and a strong healthy body. One of the most comprehensive kinds of protein available is whey protein, since it contains all the vitamins and nutrients needed to support an active lifestyle, not to mention a sustainable immune system. Whey protein production starts at the most basic level: nature. This purest form of protein comes from cows’ milk which is then processed and refined into the mixable powder you see at your local supplement shop. Generally speaking, the average person needs between .5-1 gram of protein per pound of body weight for basic nutritional requirements. But, did you know the type of whey protein you consume can greatly determine the type of benefits you’ll gain from it? The magic all comes down to how it’s processed.
A whey protein isolate powder such as BPI Sports’ ISO-HD™ is a pure form of whey protein that has gone through several levels of refinement to get to a 90% (or higher) total protein content. This type of protein has gained serious momentum lately… for its lean muscle growth and weight loss results. People just like you are beginning to see the benefits of supplementing with a whey isolate over the other more commonly used form of protein, whey concentrate. So, what’s the difference between whey isolate and whey concentrate? How do the two differ from each other? You’re probably thinking “whey protein is whey protein,” right? Wrong! The differences and benefits are actually bigger than you think.
WHEY ISOLATE VS WHEY CONCENTRATE
Whey protein concentrates are produced by taking the whey (that has been separated from the curds) and putting it through a microfiltration process that filters out a majority of the fat and lactase content, as well as other minerals. The microfiltration process results in around 20-80% protein content and a low percentage of lactase (anywhere from 3-5%, or upwards of 8%). Long with protein, it contains fat and important peptide fractions. Since it contains more than just protein, it offers consumers more health and immune boosting benefits. For whey protein isolate production, the whey protein concentrate is filtered out even more…nearly up to the point of pure protein – 90% and up. In whey protein isolate powder, there are extremely low levels of lactase, virtually no fat and very low carbohydrates.
Due to its incredible purity, whey isolates are much more rapidly absorbed in the body. For you, this means faster recovery time and truly maximizing your post-workout window (the most important time to refuel your muscles after a workout) with critical muscle building proteins. Whey concentrate protein is more comparable to a “whole food”–as the added nutrients weren’t filtered out in the microfiltration, or ion exchange processes still remain–making less desirable for someone looking to slim down. It’s also slightly harsher on the stomach, so if you’re lactose-sensitive whey concentrate protein powder might not be right for you.
BPI Sports’ ISO-HD™ harnesses all the benefits of a quality whey isolate and hydrolysate. While a whey isolate will typically be a bit more expensive due to the extensive filtration processes, ISO-HD™ actually packs more servings per container than the competition. BPI Sports’ ISO-HD™ delivers 25 grams of ultra-premium, 100% whey isolates and hydrolysates per serving. This isolate protein drives protein synthesis in your body and fuels lean muscle growth so you can get the most out of every workout.
PROTEIN POPULARITY AND CREDIBILITY
You get what you pay for…
When a product is seen as optional, just like all supplements technically are, the need for credibility becomes the first thing that consumers look for to make an informed buying decision. With the dark secret of protein spiking (adding in non-protein ingredients and passing it off as “pure”) looming over the industry, that credibility can be harder to get.
The fitness professionals at BPI Sports looked into existing quality testing programs but none of them seemed complete enough to guarantee a quality product each and every time. After extensive research, BPI Sports found ChromaDex® and began a partnership that would impact the sports nutrition industry forever.
ChromaDex®, one of the most credible, innovative, and most respected natural products companies began Third-Party Verification on all ISO-HD™ bottles as well as all other BPI Sports proteins. So what exactly does ChromaDex® test for that sets them apart from every other seal program out there? ChromaDex® Third-Party Verification testing ensures no protein spiking, quality ingredients, contaminant testing, identity testing, and final product testing. Consumers quickly started to take notice of these initiatives and it wasn’t long before the backlash of other supplement companies rolled in claiming they too went through the same practices. While third-party testing is now a common practice in the protein industry, it simply covers the FDA compliance, allowing companies to produce and sell protein products on the shelves of major or specialty retailers. This kind of testing does NOT guarantee that each and every bottle of the protein powder sold is the absolute best quality protein that contains everything it claims on the label. Without the official ChromaDex® seal of verification, there’s simply no way of knowing.
“We created the concept of this seal program more than 10 years ago,” said Frank Jaksch, CEO of ChromaDex®, BPI was one of the first to understand this and say, ‘We can’t compromise, and we’re prepared to spend the money necessary to do this’.” You can already see a massive shift in where the supplement industry is headed. Leading sports nutrition companies and national retailers are following suit and by highlighting their quality initiatives. What does this mean for you? Better quality products that you can trust!
This giant leap towards building consumer trust has not only helped ISO-HD™ become a top contender in the whey isolate category, but has also helped BPI Sports continue to be a leader in the industry when it comes to delivering the best supplements in sports nutrition.
