If you want to get big and strong, don't forget to take your protein powder. Bodybuilders have long relied upon protein powder to make sure they get the high level of protein needed to beef up their bodies through lifting weights and exercise. Protein powder is not just for bodybuilders or 98-pound weaklings hoping to bulk up, however.

Research has shown that ingesting protein powder every day can boost immune system health, facilitate the healing of wounds after surgery or injury, and promote healthy skin — in addition to fostering muscle strength and development. A human body needs protein daily because that is what muscles and tissues are built from, and there is no place where the body can store extra protein. The need for adequate protein in the human body is second only to the need for water.

Luckily, it has been found that most varied diets — including vegan — get plenty of protein through the daily intake of various food combinations. Some people like to supplement their protein intake, however, or occasionally substitute a fast, easy protein shake for a meal.

Protein powders are made from four basic sources: whey (from milk), egg, soy, and rice. Protein powders can also be a combination of one or more ingredients. These concentrated sources of protein are processed into the powdered form, to be reconstituted into liquid form as a protein shake when mixed with water, fruit juice, or milk. Additionally, protein powders can be sprinkled on cereal, stirred into soups or stews, and cooked into baked goods.

Protein powder is designed to be taken everyday as a dietary supplement. Even if you aren't a bodybuilder, starting your day with a protein powder shake can provide nutritional benefits. While many nutritionists advise consuming protein throughout the day, a healthy boost of protein first thing in the morning can stabilize your blood sugar levels throughout the rest of the day.

Some studies indicate a steady amount of excess protein may be unhealthy, especially for those with liver or kidney problems. The recommended daily dose is based on weight, age, and activity levels. Athletes should consult a nutritionist specializing in sports medicine. For all others, check the UDSA's Recommended Daily Allowance.

Since the bodybuilding boom, hundreds of dietary supplement companies have entered the market with various types of protein powders. These manufacturers offer a selection of flavors in a range of prices. Those shopping for protein powder can find it at health food stores, major grocery chains, and online through bodybuilding sites.
