Top 10 Whey Protein Powders for 2021 – Buying Guide

When it comes to boosting workout performance and building an overall muscular body, increasing protein consumption is usually needed. And right now, when it comes to the various types of protein powders on the market, whey protein is leading the pack.

Whey protein powders are made from skimmed milk and are easily mass-produced (a byproduct of cheese production), which explains their abundance and dominance in the protein ingredient market. As beneficial as it is, one disadvantage of whey protein is that some people are lactose intolerant and cannot consume dairy, and others choose not to consume dairy or animal products.

Fortunately, premium vegan protein powders are an excellent substitute for whey protein powders. We researched and compared the best whey protein supplements on the market right now to help you find a good product.

How Do We Select the Best Protein Powders – Criteria

Our team of fitness editors, athletes, and nutrition advisors helped the candidates select for the best protein powders for every goal based on nutritional quality, taste, value, and customer feedback.

We went a step further and used the following criteria to select our top picks:

  • Customer Reviews and Ratings: Our customers take protein very seriously, as evidenced by their purchases, ratings, and feedback. Every protein on this list has thousands of positive reviews and high ratings.
  • Formula: Yes, the amount of protein in a serving of powder is important. What’s more important is how it’s made, the macronutrient profile, and the manufacturer’s track record. It’s critical to have faith in your protein!
  • Flavor: If a protein doesn’t taste good, you’re unlikely to stick with it, no matter how “good for you” it is. Life is too short to drink protein that tastes bad or is chalky.
  • Price: The cheapest protein isn’t always the best deal! The price per serving is factored into all of our best proteins.

The Bottom Line

There are numerous whey protein powder products on the market, making it difficult to select the best one.

Choosing a best whey protein powder from this list can help you ensure that you’re purchasing a high-quality, safe product that will help you meet your protein needs and health goals.


  1. What Exactly Is Whey Protein?
  2. Whey protein is a protein that is derived from whey. Whey is a natural byproduct of the cheese-making process that is found in milk. If you’ve ever opened a container of yogurt and noticed a layer of liquid on top, that’s whey!

Liquid whey protein is separated from the other components of milk during the cheese making process. The whey is then processed and dried into a powder by the manufacturers. Whey protein is then sold as a supplement or added to a variety of foods and convenient protein bars to increase protein content.

Whey protein digests quickly, making it an ideal protein supplement for athletes who need a quick protein boost post-workout. Whey also has a high amino acid content, which is beneficial for a variety of health reasons.

  1. What Exactly Are Whey Protein Powders?
  2. Whey protein supplements are nothing more than powdered whey protein. To provide a well-balanced mix of nutrients, they frequently include flavoring and/or other types of protein. Athletes, weightlifters, and people on low-protein diets frequently use them.

Athletes will reap the most benefits from whey protein, but these products can benefit a wide range of people. Whey protein has far more health benefits than you might think, with numerous significant proven positive health effects.

  1. What Are the Benefits of Whey Protein Powders?
  2. Whey protein is used by a diverse group of people for a diverse set of reasons. While you may immediately think of it as a useful bodybuilding supplement when you think protein, there are many other whey protein benefits to consider, including:
  • Excellent source of high-quality whey protein
  • Packed with key amino acids
  • A high concentration of branched-chain amino acids

They are also typically high in antioxidants and BCAAs. Branched-chain amino acids (BCAAs) in particular have numerous advantages, and whey is an excellent source of these amino acids. Some whey protein powders contain the same amount of BCAAs as many of the best BCAA supplements available.

  1. How Can Whey Protein Powder Help Me?
  2. Muscle Mass: Muscle mass is the amount of muscle mass that a person If it does not promise muscle gains, it is not a whey protein supplement. After all, protein is the most important macronutrient for gaining lean mass. The studies on combining whey protein supplementation with regular resistance exercise (as well as aerobic exercise) are solid and, at this point, irrefutable.

Recovery: The first step in getting big muscles is to “heal” damaged muscle tissue, and the faster your body heals, the sooner it can move on to the “building muscle to prevent this type of muscle damage” part. Whey protein can essentially accelerate the process.

Long-term health: Protein supplementation, regardless of the source, is more than just filling macros. Protein supplements have been shown to boost antioxidant levels, boost the immune system, reduce hunger, and help regulate blood pressure.

Weight Loss: While protein powders do not directly affect weight loss in the same way that some high-quality fat burners do, eating more protein can help you exercise harder, recover faster, and build more muscle, all of which can help you lose weight.

  1. How Do I Take Whey Protein Powder?
  2. These products are typically powdered. They are usually flavored, but some are unflavored. To take a whey protein supplement, simply mix it with water, milk, or juice, or combine it with your favorite shake.

Many people like to make delicious protein shakes at home by combining a whey protein supplement with fruit, vegetables, ice, milk, or whatever other ingredients they have on hand. Others who require more calories and protein make their own homemade weight gainer shakes.

If you like variety, go for a simple whey protein flavor like vanilla or chocolate that can be mixed with a variety of other ingredients. You might want to consider getting a Blender Bottle for on-the-go use. While on the go, these handy little devices make mixing whey protein into shakes a breeze.

Blender bottles contain a small metal ball whisk that aids in the mixing of powdered supplements into water or milk with a simple shake. These convenient protein shaker bottles can be used for any type of powdered supplement, such as a good micronized creatine supplement, but they are especially useful for post-workout protein shakes.
