Protein supplements dominate the fitness nutrition world. Proteins are often referred to as the building blocks of the body and for those who depend on that body functioning in peak condition it is easy to understand why protein is so important.
Athletes need protein primarily to repair and rebuild muscle that is broken down during exercise. Protein also serves to enhance carbohydrate storage in the form of glycogen which is used for energy. All of this is crucial to optimize training and performance.
There are countless brands of protein supplements to meet this need, and they vary in more than just cost and flavor. Different types of protein may serve to satisfy various needs. All protein is not created equal. SciFighting.com has broken down the basics of 10 of the most popular protein types that may be encountered.
1. Egg Albumin is not commonly used in the powder form, but rather bought in a carton or container and cooked. People may have thought Rocky Balboa was crazy for drinking his eggs, but he knew what he was doing. Eggs are fat free and high in protein, which is great for weight-loss, plans. They are also versatile because unlike most other supplements they can be consumed in liquid or solid form.
2. Casein Protein is the only form recognized for its benefits during sleeping hours. This is due to its ability to keep the body anabolic throughout the night. It takes anywhere from 5-7 hours to fully breakdown. When used during the day it helps to curb hunger.
3. Whey Concentrate is the least expensive and most common form of whey protein. It can be used for both pre and post workout or as a snack between meals. One downside of whey concentrate is the occasional digestive irritation, which may leave some consumers a bit bloated.
4. Whey Isolates are quick absorbing and pair well with low carbohydrate or low sugar diets. Isolates are different from concentrates in that they yield a higher percentage of pure protein and can be filtered to become virtually carb, fat, cholesterol and lactose free.
5. Whey Protein Hydrolysate is enzymatically predigested for maximum absorption speed. This process provides rapid spike in blood amino acids is beneficial for protein synthesis as well as the breakdown of amino acids for energy. Though this boost may be especially helpful during a long workout or post-workout/pre-day job, it is not ideal for those looking for storage of the protein for continual use. It is also on the pricy side.
6. Milk Protein Isolate (MPI) is a combination of 80 percent casein and 20 percent whey protein. Because casein is slow to digest and whey is quick to digest, the combination of the two provides short term and long-term muscle recovery. Most forms of MPI are not lactose free, but do
Vegetable Protein Sources
7. Pea Protein is also highly digestible and as an added benefit, research shows that it may help prevent hypertension and kidney disease. It is also gluten free and is a good choice to also curb appetite. Studies have shown that pea protein leads to better satiety than milk or whey protein.
8. Soy Protein is made from soybean meal that has been dehulled or defatted. Aside from being a good vegetarian option it is loaded with glutamine, which assists in recovery. Soy has been found to boost thyroid hormone output, speed up metabolism and support cholesterol health.
9. Hemp Protein is said to be easier for the body to digest in comparison to soy. It also contains essential fatty acids, omega-3 and omega-6 in a three-to-one ratio. Its overall protein content is not as high as other forms, but it is high in dietary fiber.
10. Brown Rice Protein powder is also gluten free and has nearly as high a protein concentration as soy. It is also a good option for those who may have gastrointestinal issues, though it is not always easy to find.
