Protein is an important nutrient that performs a number of functions in the body. Protein molecules are long chains that are made up of amino acids, and are important in aiding the well being and functioning of the body. Amongst the functions performed by proteins are the building and repair of the body, muscle growth, aiding the production of hemoglobin, and forming antibodies to fight off disease and infection.

The truth is that it isn't difficult to get the necessary amount of protein that your body needs each day from a sensible and well balanced diet. However, in today's fast paced world filled with fast foods and microwave meals many people end up taking in reduced levels of good quality protein and levels of refined carbohydrates that are a bit too high.

Protein is a nutrient that is found in a range of foods, such as cheese, nuts, dairy products, fish, eggs, and meat. Those that eat meat may be able to step up the amount of protein that they consume by planning their diet more sensibly. Vegetarians may find this more difficult because they do not eat meat. Vegans will really struggle, as they don't eat meat, fish, or dairy products. And in some cases, such as with body builders and fitness enthusiasts, higher levels of protein may be required in the diet.

Supplement your protein intake

This is where protein supplements may be able to help. For those that are unable to arrange their diet so that they are taking in enough good quality protein, these supplements can provide a valuable solution. Whether you are someone that needs a higher intake of proteins, or whether your diet means that you simply do not get adequate levels of protein and you wish to increase this to the recommended daily amount, protein supplements could prove an effective way to do this.

They can also be useful for people who wish to increase specific amino acids only. For example, lysine is a protein supplement that is used for treating the herpes virus. And there are specific protein combinations sold as fat burners. Those people following diets such as the Zone diet often use specially made protein bars that reflect the dietary principles of that diet. Zone diet bars typically have 30% protein and 30% fat, and the remainder in carbohydrates.

Protein powders, bars, and drinks that are available on the market today offer a convenient way for bodybuilders to increase their lean protein intake, and for many, they represent a quick, nutritious snack. For those that get little to no protein in their diets, or who have a legitimate reason to increase their protein intake, this can prove an effective way to come closer to reaching their daily protein goals.

However, for those that already get plenty of protein in their diets, it is worth remembering that an excessive amount of protein in the diet can result in calcium loss through urine and in dehydration, as the body works to try and eliminate the excess. When using protein supplements, it is therefore important to be sensible and not to overdo it. Any excess nutrients, whether they are fat, carbohydrate, or protein, will be turned into fat and stored in the body. Thus, for people trying to lose weight, it's doubly important to consider the overall calorie value of the protein bars and supplemental drinks they consume.
