Why Is Protein Important?
Protein is essential for life and plays a role in every biological process-from synthesizing compounds, to maintaining fluid balance, to promoting cell growth, protein is a part of normal bodily function. The average body is about 18% protein and maintains roughly 50,000 different protein-containing compounds. Skin, hair, blood, bones, cartilage, hormones, antibodies, enzymes, and muscles are all made of protein. In fact, proteins exist in both the outer and inner membranes of every living cell.

Protein stands out against carbohydrates and fat because, unlike these macronutrients, protein contains, sulfer and nitrogen-two vital elements for cells of all kinds. What's more, protein can be used to create carbohydrates, and carbohydrates can be used to create fats-but neither carbohydrates nor fats can be used to create protein. In short, quality protein must be a part of a healthy diet.

How Much Should I Take
Protein requirements vary from person to person depending on personal fitness goals, diet, and demands created by training, increases may be necessary. Generally speaking, one gram of protein per pound of bodyweight, per day, has been shown to be safe and effective. Consuming anywhere between 1.2 and 1.8 grams per pound may also be effective in terms of supporting a positive nitrogen balance for muscle growth, maintenance, and repair. Protein supplements meet these needs by providing high-quality protein from numerous sources, in addition to added vitamins, minerals, and quality carbohydrates-without extra fats, sugars, cholesterol and other undesirables.

What's The Best Way To Take It

Because of the variety of proteins available, it's important to evaluate protein intake on a situation-by-situation basis. For example, slow-digesting proteins such as casein are best used to maintain a positive nitrogen balance over an extended time period-making them ideal just before bedtime or when satiation is a consideration. Whey proteins, on the other hand, act quickly, and are therefore most effective within the post-workout window, when nutrients are needed fast. After timing considerations, it's a matter of personal preference regarding delivery method and flavor.
