Is there a difference between whey protein concentrate and isolate?

alpha-lactalbumin,beta-lactoglobulin,glycomacropeptides,lact...
Yes, there may be a large difference between the two. Whey protein isolate is the most pure and concentrated form of whey protein available. It contains 90% or more protein and very little (if any) fat and lactose. Whey protein concentrate has anywhere between 29% and 89% protein depending upon the product. As the protein level in whey protein concentrate decreases the amounts of fat and/or lactose usually increase.

Whey Protein Isolate (WPI) is the purest and most concentrated form of whey protein currently available. It contains 90% or more protein and very little to no lactose and fat. WPI is also around twice the price of Whey Protein Concentrate and is only suited to athletes who are counting their grams of fat or are lactose intolerant. Whey Protein Concentrate (WPC) has anywhere between 75% and 82% protein depending upon which product you choose.

Whey Power Plus | FAQS
Whey protein and whey protein isolate are derived from the milk proteins of cows or goats during the cheese manufacturing process. Whey was originally used as an animal feed for many years. Veterinarians noticed the animals became healthier when they were fed whey, which led to research into the benefits of whey. In 1992, a process was developed that extracts the pure amino acids from milk proteins leaving behind all the sugar (lactose), fat, and cholesterol.

Are there any side effects associated with whey protein isolate?

Whey Power Plus | FAQS
Whey protein increases glutathione levels in serum (blood) and liver. Glutathione is the body's most powerful antioxidant and plays a key role in immune function. When liver glutathione levels rise, the liver is able to more effectively detoxify the body. Some people (especially those who have had a highly toxic diet, or exposed to high levels of environmental toxins) may have a mild temporary reaction to these mobilized toxins as the liver is removing them from storage in body fat.

What is the difference between colostrum and whey protein?

Frequently Asked Questions - Glutathione - MA+ Complex -link...
Colostrum has practically no cysteine molecules, the substrate needed for the intracellular production of glutathione. Colostrum is composed primarily of immunoglobulin and some lactoferrin - at least during the first 26 hours of production. As far as we know from experiments and clinical trials done in Germany, colostrum has shown no effect on the immune system due to the fact that the mechanism of action on the immune system is via stimulation of the synthesis of glutathione.

What is the difference between soy protein and whey protein?

Whey Power Plus | FAQS
Soy protein comes from soybeans, which is a legume-a source of carbohydrate. There are several problems with soy protein. The protein from soy is not complete -it is missing one of the essential amino acids, called methionine. Most soy protein powders are fortified with this amino acid, making it complete. However it is important to know that most soy protein products are processed using hexane and other toxic chemicals, which are not safe for the body.
