Protein is one of the essential nutrients our bodies need. Our muscles especially require it for maintenance and growth. For most people, around .3 grams per pound of body weight is the recommended daily intake. However, athletes in general and bodybuilders in particular need far more; around 1.25 grams per pound each day. These people need more protein to build muscle and fuel their bodies for their exercise regimens.
It's not only how much protein you get though; it's also where it comes from that matters. While most of us get all the protein we need from our diets, athletes often need 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.
The four protein sources common in protein supplements are whey, soy, casein and egg. While some protein supplements are made from just one source, most often there will be protein from two of these sources in a given protein supplement.
Whey protein comes from milk. It is the most common choice in protein supplements. This type of 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 often mentioned as being the best protein supplements. This protein comes from egg whites and is quickly and completely digestible. Containing all of the essential amino acids, it's also a popular ingredient in protein supplements. However, there are those who are allergic to eggs and should not use protein supplements containing egg protein.
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.
Choosing the right protein is about choosing what your body will tolerate the best and what protein will work for your exercise habits the best. You should consider all pros and cons of each type before you make your final decision about protein supplements.
