I. Whey Protein Isolates:
Whey protein isolate is a highly filtered and pure form of whey protein that contains little to no lactose, fat, cholesterol, carbohydrates, and calories. This makes it an ideal choice for people who are intolerant to lactose, as well as those looking to maintain muscle mass while losing fat.
Whey protein isolates contain at least 90% protein content and are typically the best quality protein type on the market. This higher protein content means that you’re getting more of the muscle-building benefits that you want from whey protein.
II. Whey Protein Concentrates:
Whey protein concentrate is the other common form of whey protein. Its main difference from whey protein isolate is that it contains more lactose, fat, and carbohydrates. However, it also contains more of the beneficial components found in whole milk.
The protein content in whey protein concentrate varies depending on the level of concentration, with most whey protein concentrates containing between 70-80% protein.
III. Whey Protein Peptides:
Whey peptides, more commonly known as whey protein, is a supplement made from the liquid part of dairy products called milk plasma.
What makes this protein so beneficial is that it contains long strands of amino acids which are the building blocks of proteins in the human body. This is why people who are looking to gain muscle or have a faster recovery rate from strenuous workouts benefit from taking whey peptides.
IV. Other Important Ingredients:
- Lecithin: Lecithin is an ingredient that is often used to improve the mixability of food products.
- Acesulfame potassium: Acesulfame potassium is a sweetener that’s about 200 times sweeter than sugar. It’s controversial in some circles but appears to be safe when consumed in small amounts.
- Aminogen: Aminogen is a blend of enzymes that help digest the protein very fast and reduce gas.
- Lactase: Lactase is an enzyme. It breaks down lactose and helps to digest the lactose easily.
