Whey Isolate vs Whey Blend vs Casein Protein
Which one is right for you?
The biggest question I get when people want to buy whey protein is, "What are the different types of whey, and which one should I buy?"
The answer is a little bit complicated, so let's go through each one individually.
Whey Protein Isolates
Isolates are literally isolated proteins. Anything that says it has "whey" in it means that the protein comes from milk. That means the manufacturer "isolates" the powder as much as possible. Furthermore, that means the company takes out as much fat and carbohydrates as possible so you get the purest product available.
The reason a company would do this is because the product is very pure, and is digested quickly by your body.
Whey Protein Blends or Concentrates
Blends are also called concentrates. Thus, they are synonyms. They are just another milk protein, but they are not as pure isolates. They are still great option, but they contain more carbohydrates and fats so it will take longer to digest than an isolate. The reason that happens is because fats are calorie dense macro-nutrients (macro-nutrients include: Carbohydrates, Fats, and Proteins). Because they are not as pure as Isolates, whey blends tend to be a little bit better bargain than an isolate. I mostly take blends because after a hard workout, my body is starving for some good fats and carbs as well.
Casein is another milk protein, but unlike whey, which is quickly digested by the body and absorbed for muscular repair, Casein protein can take anywhere from five to eight hours to fully digest. That is great if you work for an eight hour shift!
Which one should I take?
That is a great question! It entirely depends on what time of day, and what you are going to do. Whey isolates and whey blends should be taken any time that you need fast digestion. If you just got done working out, then take the blend or isolate. Just remember that whey blends and whey isolates are digested and absorbed by the body in 15-45 minutes. So after you just got done with your exercise routine is a great time to take those proteins.
Casein is ideal right before bed. You are going to spend, hopefully, 8 hours sleeping; so, your body is going to need those slow digesting molecules to replenish your body all night long. It is also a great idea to take your casein during your lunch break at work; well, as long as you don't have a labor intensive job. If you are just on your feet or if you have a desk job, casein during your lunch will help you keep your protein content high in your body so you can build muscle, burn fat, and get into shape faster than if you don't feed your body what it needs!
