The most basic form of whey protein is whey protein concentrate. By law, being marked as concentrate means that at least 35 to 80 per cent protein by weight must be the product. Concentrate also tends to be the cheapest sources of protein supplementation due to its simpler process. Whey protein concentrate contains the same essential amino acids-carbohydrates and fats are just a slightly higher serving.
Whey Isolate is the more pure form of protein out of the two. Isolate is classified by being more than 90% protein by weight. This type of powder is more expensive due to the increased protein quality, purity, mix ability and improved digestion. The whey is isolated from the fats and carbohydrates, lowering it in carbohydrates and lactose but higher in pure protein.
Whey Protein Hydrolysate:
Hydrolysed whey is a pre-digested form of whey protein. It contains approximately 99% protein and dissolves in water much faster than whey protein. Produced by protease-mediated intact whey protein hydrolysis, it has an amino-acid composition identical to intact whey protein and can increase amino acid plasma concentration more quickly and to a higher level than intact whey protein after ingestion.
Casein is a slow release, slow digesting dairy protein that can be found in milk and cheese. When Casein is consumed it will reach its highest level of protein synthesis and amino acids in about 3 and 4 hours. Casein protein is best taken before bed as it releases amino acids slowly and feeds muscles and helps recovery whilst you sleep.
Hemp protein is a vegan protein of high quality that contains all nine essential amino acids, plus fibre, healthy fats and minerals. One of the more popular varieties, made by grinding pressed hemp seeds into a fine powder, is hemp protein powder.
Eggs are an outstanding source of protein of good quality. They have the best protein digestibility-corrected amino acid score out of all whole foods. Eggs are one of the best foods to reduce your appetite and to help you stay full for a lot longer. As they are unable to digest lactose, many individuals are intolerant to dairy products, thus causing many gastrointestinal problems such as bloating and stomach cramps. Therefore, egg white protein powder provides a convenient and high-quality alternative to more conventional milk proteins such as whey and casein.
