Bodybuilding has come a long way from being a hobby for health conscious people, it has turned into a science in itself. A billion dollar industry with millions invested just in research to get that extra gram of protein in your scoop. And everyone who has played and burnt his hands with science would knows that the sickest part in science lies in its jargons.
This section will be a glossary for you and help you make sense out of what that smug-egotist-bodybuilder in the gym or the lazy shopkeeper at the store is talking about.
Isolate
An isolated protein source is one that has been chemically purified to remove most everything other then the actual protein source. Generally isolates are 90%+ pure protein.
Concentrate
A concentrated protein source is not as pure as an isolate, and generally contains 70 to 85% of the protein source. Concentrates contain more fats, carbohydrates, and in the case of whey protein, more lactose.
Blends
A protein blend is a combination of various protein sources and purity levels. A blend can be more cost effective then a pure isolate, and can also offer the benefit of having both fast digesting and slow digesting protein sources.
Amino Acids
Amino acids are the building blocks of protein. While there are over 100 total amino acids, only 20 amino acids are considered standard. These standard amino acids are separated into two categories: essential and non-essential amino acids. Essential amino acids cannot be created in the human body, and must be obtained from food. Non-essential amino acids can be synthesized, or created, in the human body.
BCAA. Branched chain amino acids (BCCA)
BCAA is a term that refers to a chain of the three essential amino acids leucine, isoleucine and valine. The combination of these 3 essential amino acids make up over one-third the skeletal muscle in the body, and play a vital role in protein synthesis.
Weight Gainer
Weight gainers are high calorie protein powders meant to assist bodybuilders and athletes who are in need of rapid weight gain. They can be used as meals on the go, or in between meals as a means of adding extra daily calories.
Meal Replacements
Meal replacement protein products are considered to be entire meals in and of themselves. They contain a formulated nutritional and macronutrient blend that provides not only enough protein, but also an appropriate amount of carbs, healthy fats and vitamins and minerals.
Recovery
A recovery blend is a protein supplement that contains any number of additional, non-protein supplement products meant to aid in post-workout recovery. These supplements range from creatine to multivitamin and minerals, and larger doses of glutamine and taurine.
Slow Digesting
A slow digesting protein source provides a long term stream of protein and amino acids, meant to assist in keeping a positive nitrogen balance for longer periods of times. A slow digesting protein is a great choice for in between meals.
Fast Digesting
A fast digesting protein source, such as whey protein, acts quickly to help regulate bodily nitrogen levels, especially after periods of fasting. A fast digesting protein is also beneficial as a post-workout protein source.
Energy Bar
Energy bars provide a quick, healthy and sustained source of energy when you need a pick-me-up in between meals. While an energy bar does contain some protein, in general, it does not contain as much protein as a protein bar.
Whey Isolate
Whey isolate is a more expensive version of whey protein. It is a higher quality protein source with a higher biological value (BV), and contains less fat and lactose per serving then whey concentrate. Whey isolate generally contains 90 to 98& protein, while whey concentrate contains 70 to 85% protein.
Whey Concentrate
Whey concentrate is a more cost-effective member of the whey family. It requires less processing time, but also contains more fat and lactose. Whey concentrate is 70 to 85% protein.
Whey Protein Blends
Whey protein blends are specialized protein formulas that contain both whey Isolates and whey concentrates. Whey protein blends are generally more cost effective then whey isolate, and have a higher protein percentage ratio then whey concentrates.
Casein Protein
Casein proteins account for 80% of the protein in milk. Casein protein is a slow digesting protein that is isolated from milk. It is 92% protein, and has a very “thick” taste. Because of this, it is a very popular protein in weight gainers. Casein protein, although it has a lower BV value then whey, is more efficiently used to build muscle. Because casein protein is used by the body to build muscle, and less is used as a energy source, casein supplementation encourages the body to use carbs and stored fat for energy. Casein is also very high in the popular bodybuilding supplement glutamine.
Egg Albumin
Egg albumin is the egg white. It is popular in bodybuilding circles because of a higher essential to non-essential amino acid ratio, and because egg whites contain less cholesterol then egg yolks. Eggs are often considered the king of natural food proteins because of their high essential amino acids levels. Egg protein is the best alternative for those that are lactose intolerant.
Soy Protein
Soy protein is high quality, but not as efficient as milk or casein protein, It is a fast digesting protein source that has an average amino acid profile. Because of this, it is not the most desirable protein source for those looking to build muscle.
Soy Protein Isolate
Soy protein isolate has a greater BV then regular soy protein, meaning that more of it is utilized by the body. But soy protein isolate is of lower quality then soy protein.
Goat Milk Protein
No other protein source has a higher bioavailability then goat milk protein. In addition, goat milk protein is extremely high in BCAA and is 100% lactose free. Its BV rating of 104 is superior to most foods, including eggs, which have a 100 BV.
Wheat Protein
Wheat protein is a healthy and natural alternative to dairy and egg-based proteins. It is lactose and cholesterol free, and is perfect for vegetarian bodybuilders and athletes. Wheat protein is also very high is glutamic acid.
Pea Protein
Pea protein is a 100% gluten free protein source that is a great alternative for vegetarians. As with wheat protein, pea protein is lactose free and does not contain any cholesterol. It is very easy to digest and is rich in amino acids.
Complete Milk Protein
Complete milk protein is the dried protein from milk, with the carbs and fat removed. Milk protein is nutritious, and contains calcium and high levels of other vitamins and minerals. Complete milk protein contains both whey and casein proteins.
