UNDENATURED WHEY PROTEIN ISOLATE
Understanding why is it the best- or not.
What makes undenatured whey protein isolate ‘undenatured’?
Whey protein is a fast-absorbing protein that has many health benefits, such as better muscle growth. Whey is a byproduct of the cheese-making process, has the highest biological value of any protein. It is quickly absorbed into the body.
Undenatured whey protein isolate is a specific type of whey.
There are three main types of whey proteins on store shelves. The difference between the whey protein forms is the filtering process used. Whey protein concentrates are the cheapest option.
Less expensive would be a better way to put it. Same results as isolate, yet costs less $.
Thanks to recent molecular genetics, we now know that whey isolate (90 to 95 % protein) and high end whey concentrate (70 to 89% protein) produced identical results in increased muscle protein formation, and reduction of fat deposits.
After most of the fat and lactose is removed, the structure of the proteins is more important. The structure of the proteins depends on the quality of the milk. Whey protein isolates are a bit more expensive but may have more protein per gram, yet the results with concentrate have proven to be identical.****
Whether whey protein is denatured or an undenatured whey protein isolate depends upon the process.
The processing methods of whey protein
Whey proteins become denatured due to exposure to extreme heat. This high heat damages the integrity and amount of vitamins, minerals and important compounds. The manufacturing process of whey powders varies depending upon the type of whey protein being made.
Denatured and undenatured whey proteins are different and there are benefits to using the undenatured whey protein isolate. Since undenatured proteins have fewer steps in the process, and do not use the high heat method they lose fewer vitamins, minerals and contain a greater amount of bioactive compounds. Bioactive compounds can help cardiovascular health.
What does ‘isolate’ mean in undenatured whey protein isolate?
Whey isolates yield a higher percentage of pure protein and can be filtered enough to be virtually lactose free, carbohydrate free, fat free, and cholesterol free.
Sources for the cows that produce the milk for whey are the most important!
One more crucial element when choosing the right whey protein is the source of the cows that the milk comes from in the first place. I will cover this more in depth at a later date, but for now I will tell you this- you want Organic whey, from grass-fed cows where there are no pesticides or herbicides used. Look for New Zealand cows as a source.
The best whey protein based on all of this information
The best protein for all the reasons stated above is undenatured whey protein isolate concentrate from grass-fed cows from New Zealand.
The best resource and with hands down, the absolute best tasting whey protein is IsaPro, undenatured whey protein concentrate.
You can purchase this amazing product in delicious creamy natural vanilla or meal replacement IsaLean Pro Shake. (below)
Undenatured whey protein is extracted by cold-membrane filtration. It costs more, but it’s the only whey to go!

Dr. Colgan is a world-renowned research scientist and a leading expert in anti-aging. He has provided nutrition, training and anti-aging programs to more than 11,000 athletes, including many Olympians. He is director of the Colgan Institute, a research facility specializing in nutrition and exercise on athletic performance, along with prevention of chronic degenerative disease, and prevention of degeneration of the brain.
*Note: Although the majority of Isagenix IsaLean Shake protein comes from undenatured whey protein, there is some undenatured milk casein included because studies show it helps you feel full, and maintains blood sugar levels.

** Isagenix only uses undenatured whey protein at 80 percent or more protein containing very low amounts of lactose.
***Isagenix only sources dairy proteins from cows that are pasture fed in New Zealand.
