1. What is whey protein with isolate and concentrate and where does it come from?
Whey protein isolate is the highest yield of protein currently available, and it comes from milk. Because of its chemical properties, whey protein is the easiest to absorb into your muscles. Obviously, with its high concentration, whey protein isolate is the best to use.
Whey protein isolate is also 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 also comes from milk. 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.
Comparing the two, whey protein isolate is slightly more expensive than concentrate - because of it's higher quality (more pure), and have a higher biological value (BV). Whey protein isolate contains more protein with less fat and lactose per serving. Usually, isolate contains 90-98% protein while whey concentrate contains 70-85%.
Most of the whey protein powders you find today will contain mostly whey protein concentrate with some whey isolate mixed in. You'll also find a lot of pure whey protein concentrate, and some whey protein isolate. However, getting both from one source gives you the best of both worlds!
2. What does whey protein with isolate and concentrate do and what scientific studies give evidence to support this?
Whey protein with isolate and concentrate is incredibly important for your body. It provides you with all the building blocks to produce amino acids that will be used for building muscle tissue.
This protein combination contains the perfect blend of overall amino acid makeup for optimal performance in the body. Additionally, both hormonal and cellular responses seem to be greatly enhanced with supplementation of whey protein too! Not to mention the benefits whey protein has on the body's immune system according to documented scientific research.
Whey protein also plays a role as an antioxidant and helps support a health immune system. Most importantly, consistent whey protein intake coupled with exercise will result in consistent muscle building.
Studies have been conducted that compare whey protein to other sources. They have found that whey protein contains the perfect balance of amino acids along with other nutrients to maximize your fitness and strength goals.
3. Who needs whey protein with isolate and concentrate and how much should be taken? Are there any side effects or symptoms of deficiency?
Whey protein is very important for bodybuilders, people dieting, and just about anybody! Since athletes and bodybuilders work out quite often, protein levels become depleted. By being a direct precursor to building muscle and providing essential amino acids, such as L-glutamine, the content from high quality whey protein will help one's muscles recover and grow faster by bringing up the levels of protein.
With dieting and those wishing to lose some extra fat, whey protein can be very useful because a good intake of protein balances blood sugar levels, while carbohydrates cause blood sugar levels to fluctuate. When the blood sugar levels stay balanced, one is not as prone to rampant eating and has more energy and will see greater fat loss.
Training athletes often consume 25 grams of whey protein per day. Bodybuilders who want serious gains and are thus burning more calories, generally consume 150 grams per day. Extremely high doses of whey protein is not recommended, as this will cause the body's liver to be overloaded and you won't get the same benefits as with a consistent lower amount taken three to five times per day.
Whey protein allows a person to control his or her diet effectively. Most people who want to change their body for the better could benefit from whey protein supplementation. However, since protein is naturally found in many food items deficiency is usually not a problem.
