Protein Supplements

No matter if you’re a competitive bodybuilder, part-time fitness enthusiast, elite athlete, or vegan, it seems that these days everyone is jumping on the protein powder bandwagon—and rightly so. From weight lifters to weight watchers, more and more fitness-minded people are choosing protein powder to meet their specific nutritional goals.

Protein powder supplements are concentrated forms of animal and/or plant protein that are used for muscle growth, tissue repair, nutritional requirements, and as a way to curb the appetite.

But in particular, if you’re after bigger muscles, enhanced performance, and better overall results from your training, then whey protein is going to be your best bet.

How to Choose the Best Protein Powder

While nourishing your muscles on the go has never been more convenient, some products are better than others, and making a decision about which powder is best can be a real dilemma. On the one hand, you have your animal-based powders made from whey, eggs, and casein. On the other hand, there’s a wide variety of vegan and plant-based protein powders to choose from, including those made from soy, rice, peas, and hemp.

Even after you’ve settled on the type of protein, you still need to be on the lookout for yet another aspect: additives. You’ll find that many powders being sold are full of artificial colors, sweeteners, and other additives, which ironically makes some of these products some of the unhealthiest foods available.

The Top 5 Protein Supplements

Based on extensive research, testing, and reviews, we’ve assembled the following list of the best protein powder supplements available. Most of these products are somewhat of a well-kept secret among elite athletes and bodybuilders, and you won’t find them on the shelves of GNC or Walmart, or for sale on Amazon.

Whether you’re looking for protein to support workout performance, weight gain and bulking, meal replacement and weight loss, or one that’s vegan-friendly, you’ll find something on this list for just about everyone.

Benefits of Protein Powder

Protein is a vital component of a well-balanced diet. Because of the large amounts of protein found in protein powders, these types of supplements are a great way to get more protein into your diet while being low in calories, fat, and carbs .

Here are a few benefits you can experience from adding protein powder to your diet:

  • Muscle growth: Protein is crucial for building and maintaining muscle mass. Since they’re processed, protein powders deliver more bioavailable amino acids than you would get from just eating high-protein foods. These amino acids are vital for encouraging muscle growth and repair.
  • Weight loss: Protein powder can help to promote your efforts for rapid weight loss by increasing caloric burn, reducing appetite, and maintaining lean muscle mass. Because protein powders are often lower in calories and fat than protein-rich foods, you can add one or two scoops to your smoothies and shakes (or even foods like baked goods and pancake batter) for an easy way to get these weight loss benefits.
  • Maintain Optimal Nutritional: From vegans and vegetarians, to fitness enthusiasts and those leading busy lifestyles, there are any number of reasons why you might need more protein in your diet. Blending protein powder with fruits, vegetables, and healthy fats to make a nutritious shake or smoothie can be a quick, healthy, and delicious meal replacement.

The ease and convenience of using protein powder makes it an excellent choice for on-the-go nutrition like shakes and smoothies – but you can also add it to other foods to increase protein intake. Some ideal foods to add your protein powder to include things like oatmeal or yogurt because it dissolves easier in foods with a higher liquid content. Other good foods to add whey with are things like peanut butter, which has a higher fat content that helps combat the dryness that whey protein sometimes can cause.

With all this said, remember you will need to put in the effort at the gym for any protein powder to help make your muscles grow. After all, whey protein alone won’t develop big muscles – for that you need to be consuming more calories than you’re burning (aka, a calorie surplus) and getting plenty of total protein (ideally 1 gram per pound of body weight).

Which Type of Protein Powder is Best?

This is the Whey

Studies show that taking whey protein powder combined with resistance training can help the body to maintain lean muscle mass while boosting both upper- and lower-body strength.

However, if you’ve ever been shopping for protein powder you know that there’s a dizzying array of different types of protein to choose from. So what make whey the protein of choice?

One of the main reasons for using whey protein is because it contains a wide variety of amino acids that aren’t found in plant-based protein supplements, like those made from pea or hemp proteins. The fact is, no plant-based protein is a complete protein, and they don’t naturally contain all the amino acids needed for muscle growth and repair.

Whey protein also contains a large amount of essential amino acids, including leucine. Leucine is required to “switch on” muscle growth on a cellular level.

Types of Whey Protein

Generally speaking, there are three basic types of whey protein:

  • Whey protein concentrate (WPC): Just like you would imagine, this type of protein is concentrated. WPC provides more nutritional content than other types of whey due to the way it’s processed.
  • Whey protein isolate: This form of protein is digested faster than WPC, and it’s typically stripped of most of its carbs and fats. This makes whey protein isolate suitable for those who are lactose intolerant, but because most of the fat has been removed, it’s also missing a lot of fat-soluble vitamins.
  • Whey protein hydrolysate: Hydrolysate whey protein goes through a process where peptides (the building blocks of protein) get broken down into a quicker and more easily digestible form. Because of the way it’s processed, this type of protein can have a bitter taste.
