Whey Protein Questions and Answers

Below are some Frequently Asked Questions about Whey Protein:

#1. What is Whey Protein and where does it come from?

Whey Protein is one of two types of protein that comes from milk (the other type is casein protein). Whey Protein is made during the process of cow's milk being turned into cheese, wherein the whey protein is a by-product of the process. The great news is that Whey Protein is a rich source of branched chain amino acids (BCAAs), containing the highest known levels of any natural food source.

Thus its good for vegetarians too, but not for Vegans because its made from milk.

#2. Do any other Foods contain Whey Protein?

No, its only found in the by product of the cheese making process. You can find different kinds of protein in other foods (especially meat). There are a variety of different foods that contain high levels of protein, but they're not as high in protein as you might think.

    Lean red meat (20% protein)
    Chicken/turkey (20% protein)
    Fish (20% protein)
    Eggs (6-10% protein)
    Cheese (10-30% protein, but also high in fat)

Thus if you get Whey Protein Powder you're consuming something that is often 50 to 90% protein, depending on the brand. You will need to read the label and possibly do some math to discover the exact percentage. eg. Six Star Muscle Professional Strength Whey Protein is 66.6% protein.

#3. What Types of Whey Protein are There?

There are 2 major types of whey protein:

Whey protein concentrate, which also contains some lactose and fat and is roughly 75% protein by weight. Its cheaper to buy whey in this form, but you'd better be feeling energetic and not be lactose intolerant.

Whey protein isolate, the purest form of whey protein has been processed to remove fat and lactose. Typically whey protein isolate is about 90%+ pure protein by weight, and this is the type commonly used in whey protein powders.

There is also whey protein blends, a mix of the above two, and is typically used for making protein bars and whey protein powders. A blended mix is slightly cheaper than pure isolate, but still boasts a good chunk of protein.

#4. What does Whey Protein do?

Whey protein provides the body with the necessary amino acids for muscle building, strength and recovery. Bodybuilders and professional athletes use whey protein supplements to help increase size, strength and speed up recovery times.

Whey is also easy and fast ingesting, meaning it gets to where it's needed in the body quickly. It is best used right after a weightlifting workout as it plays a huge roll in post-workout nutrition, when your body is in a catabolic state and needs a fast injection of protein.

Whey protein also works as an antioxidant to boost the body's immune system, helping to create a stronger immune system. The end results include: Increased lean muscle mass; Decreased recovery times and faster muscle repair; Reduced post-workout muscle breakdown; Increased metabolic rate.

#5. Are there any side effects?

None whatsoever. Its protein, a necessary amino acid that your body needs.
