Frequently Asked Questions About Whey Protein Powder

What Is Whey Protein?

Whey protein is a form of protein derived from whey. Whey is found in milk, and is a natural byproduct of the cheese making process. If you’ve ever opened up a container of yogurt and noticed some liquid at the top – that’s whey!

During the process of making cheese, liquid whey protein is separated from the other elements of milk. Producers then process and dry the whey into a powder form. From there, whey protein is sold in supplement form, or added to various foods and energy bars to increase protein content.

Whey protein is very rapidly digested, which makes it an ideal protein supplement for athletes who need a quick boost of protein post-workout. Whey also has a very high amino acid content, which is great for a number of health benefits.

What Are Whey Protein Powders?

Whey protein supplements are simply pure whey protein in its powdered form. Often they will contain flavoring and/or other types of protein to deliver a balanced blend of nutrients. They are commonly used by athletes, weightlifters, and people on low-protein diets.

Athletes will experience the most whey protein benefits, but in reality, many different people can benefit from taking these products. The benefits of whey protein are much more extensive than you might think, with many significant proven positive health effects.

What Kind of Whey Protein Powders Are There?

There are a couple different whey protein types used in these products. The main types are:

  • Whey Protein Concentrate: Perhaps the most commonly used form of whey, whey protein concentrate is fast-acting, affordable, and widely available. Concentrate typically contains around 80% protein, although it can vary widely. Whey protein concentrate is also relatively high in lactose, so those folks with a lactose sensitivity should avoid concentrate.
  • Whey Protein Isolate:Widely considered the best form of whey protein powder, whey protein isolate typically contains 90-95% pure protein. It’s very low in fat, and in lactose, so even people who are lactose intolerant can often be fine taking good whey protein isolate powders. Isolate is toted as the “premium” form of whey, and we tend to agree. With that being said, it’s higher purity and protein content make it a bit more expensive than more affordable alternatives like whey protein concentrate.
  • Hydrolyzed Whey Protein: This form of whey involves protein that has been broken down to increase absorption rates. Basically, long-chain proteins are broken down into shorter chains, known as peptides. This makes the protein easier to digest. Hydrolyzed whey protein is typically fairly expensive, and is not commonly used as the main type of whey, although it may be added to good whey protein blends.

Those are the main three types of whey, although there are others. Many whey protein products will contain a mix of these forms.

What Are the Benefits of Whey Protein Powders?

Whey protein is used by a wide range of people, for a wide range of reasons. While you may immediately think of bodybuilding when you think protein, in reality there are a whole lot of different whey protein benefits, such as:

  • Excellent source of high-quality whey protein
  • Packed with key amino acids
  • High concentration of branched chain amino acids

They are also usually packed with antioxidants and BCAAs. Branched chain amino acids (BCAAs) in particular have some very important benefits, and whey is one of the best sources of these amino acids.

How Do I Take Whey Protein Powder?

These products typically come in powdered form. They are generally flavored, although some are unflavored. For the most part, to take a whey protein supplement you’ll just want to mix it with water, milk or juice, or mix it into your favorite shake.

At home, many people like to make delicious protein shakes, using a whey protein supplement, plus fruit, veggies, ice, milk, or whatever other ingredients are laying around. If you crave variety, you’ll want to choose a simple whey protein flavor, like vanilla or chocolate, that is flexible enough to mix with a variety of other ingredients.

For on-the-go use, you may want to consider picking up a BlenderBottle. These handy little devices make mixing whey protein into shakes a breeze while out and about.

Blender Bottles have a  small metal ball whisk in them that helps mix powdered supplements into water or milk with just a simple shake. They are useful for any type of powdered supplement, but can be particularly useful for protein shakes post-workout.

When Should I Take a Whey Protein Shake?

If you’re wondering when to take whey protein powders, that depends on why you’re using them. If you’re taking a whey protein powder as a way to help recover from your workouts, you’ll want to consume a serving of protein immediately following your workout.

In order for your muscles to recover as quickly and completely as possible, they need protein and carbohydrates as soon as possible. So, if you’re heading to the gym, either bring a shake with you (use a BlenderBottle!) or be prepared to take some protein immediately after you get home.

If you are using whey protein as a general health supplement, the timing is of less importance. You can simply use protein powder as a supplement to your diet. While whey protein is a great way to supplement your diet, note that it is not a complete source of nutrients, so if you’re planning on using it as a meal replacement, do some research and speak to your doctor about what else you should be consuming to meet daily nutritional needs.

Are There Any Side Effects of Whey Protein?

When taking as directed, whey protein is a very safe supplement and the vast majority of people don’t experience any notable whey protein side effects. With that being said, there are some potential side effects, particularly if the supplement is taken in excess, such as:

  • Digestive issues, including increased bowel movements, nausea, bloating and cramps
  • Headache
  • Thirst
  • Reduced appetite
  • Fatigue

Whey protein is regarded as a safe supplement when taken as directed. As long as you don’t take too much, you shouldn’t have any problems.

One thing to note is that since whey protein powders are made from dairy, those who are lactose intolerant may experience lactose-related side effects from consuming whey protein. Whey protein isolate contains significantly less lactose than whey protein concentrate, so keep that in mind if you are sensitive to lactose.

How Do I Pick a Good Whey Protein Powder?

There are a ton of different whey protein supplements out there, so choosing the best one for you can sometimes be a challenge.

  • Protein Content: First and foremost, take a close look at the ingredient label on any product(s) you’re considering to get an idea of how much protein is in each serving. Typically, you’ll find products in the 20-30g per serving range. Also, keep in mind that some whey protein powders also contain other types of protein mixed in, such as casein. This is not necessarily a bad thing, but it’s something to take note of.
  • Type of Whey: There are a few different types of whey protein, each of which offer particular pros and cons. In general, whey protein isolate is the most recommended, but other forms such as whey protein concentrate and hydrolyzed whey protein are also good choices. Many whey protein powders contain a mix of these types to provide a balanced blend of benefits and nutrients.
  • Flavor: The vast majority of whey protein powders are flavored. Clearly, you’ll want to find a flavor you’ll actually enjoy – otherwise you won’t want to take it! Since there are a ton of flavors out there, to select a good one for you try to think about how you plan on using it. If you want some flexibility; i.e. you want to be able to drink it straight, mix it in smoothies or toss it in pancakes, go with a simple flavor like vanilla or chocolate. If you’re more likely to just drink it straight mixed with milk or water, go with whatever flavor sounds tasty to you! You can also read user reviews to see what other folks think of the flavor.
  • Brand Quality: Since there are so many companies making whey protein supplements, you’ll want to pay attention to the company behind each product you’re considering. Choose products from reliable, trustworthy companies with good reputations. On our list above, we’ve only selected products from excellent and trustworthy companies.
  • Value: Whey protein is relatively inexpensive, but if you take it every day it can certainly add up. Typically, you’ll be looking at somewhere between $0.50 and $1.50 per serving, which can translate to $15-$45 a month for daily users. So, take value into account when choosing a product. But, also keep in mind that cheaper does not mean better, so try to find a quality product at a reasonable price.
