Choosing Protein Supplements: The Four Important Protein Sources
Protein is an essential nutrient for the body, especially for the muscles. The general recommendation is an intake of around .3 grams of protein for each pound a person weighs. For athletes and bodybuilders, though, the requirement is higher because the body is working harder and demands more protein. The recommendation jumps from .3 to 1.25 grams for this group of people.
It's not only how much protein you get though; it's also where the protein comes from that matters. While most of us get all the protein we need from our diets, athletes often need protein supplements to provide them with enough of this important nutrient. The protein used in protein supplements is nearly always from the same four sources. Each is used differently by the body and are more or less suitable for different individuals.
These four sources used in most protein supplements are egg, whey, soy and casein. There are protein supplements which use only one type, but it is more common to have two of these proteins in a single supplement.
Whey protein comes from milk. It is the most common choice in protein supplements. Whey protein is made up of nonessential and essential amino acids. Essential amino acids are not made by the body naturally and must come through diet. The body takes well to whey protein and will use it easily and safely. The only concern about whey protein is that it is not safe for those with a milk allergy or who are lactose intolerant. Concentrated whey protein is most often preferred as it more available and less expensive. Concentrated forms contain anywhere from 30 to 85% protein. The isolate forms will have about 90%, but are more expensive and harder to find. Whey protein helps to boost the immune system, provides amino acids and helps for quick muscle recovery and prevents muscle breakdown.
Soy protein is derived from soy flour. This is the most complete vegetable protein known and like whey protein, there are isolates and concentrated forms available; isolates are higher in protein but more expensive. Easily digestible, soy protein is suitable for everyone except for the small number of people who are allergic to soy. Soy protein can be added to foods easily and is beneficial in lowering blood cholesterol.
Egg protein is an excellent protein source. Derived from egg whites, egg protein contains all of the essential amino acids and is easily digestible. It's generally considered to be the best source of protein for supplements, but as with other proteins, there are some people who are allergic and should not use it.
Casein protein comes from milk, but unlike whey it is slow to digest. It is slow acting and therefore often used in combination with faster acting proteins. It works well meals prior to workouts. It also is a great choice to take just before bed.
When you're shopping for protein supplements, always read the label to make sure that the protein sources used are suitable for your needs and that you can safely ingest. Protein supplements can be a great thing " but make sure you choose well.
