Buyers Guide

We shared some amazing brands and types of whey protein in the list above but it’s also important to understand what you are buying and the role protein plays when it comes to muscle growth. Continue reading for a complete buyers guide…

When weight gain in the form of lean muscle mass is your goal, then you need to realize one thing – protein is your best bet during this type of journey.

Regardless of the advice you are looking at; you will notice that protein is most often the most recommended nutrient or supplement for anyone who wants to gain weight.

While it is relatively easy to determine that protein is a critical factor for anyone who wants to gain weight, you might find the process of identifying the best whey protein for weight gain quite a challenge.

A quick search on any marketplace or even a visit to your local supplement shop gives you a significant variety of whey protein products that you need to filter through and choose from.

We’ll take a closer look at what you need to look at when searching for the best whey protein that will help you gain weight. We will also share our selection of the top products that you can buy and take advantage of right now.

The Role Of Protein In Muscle Growth And Weight Gain

Protein is part of the micronutrients that your body needs to function properly. This particular micronutrient plays an important role alongside both carbohydrates and fats.

The most popular association when it comes to protein is with muscles. This is an accurate association to make, as protein does play a big role in allowing muscle tissue to grow and even recover following intense training. This, however, is not the only function that this micronutrient plays in your own body.

Proteins are considered complex molecules. The majority of the functions that are performed in every single cell found in your body are regulated by proteins. Additionally, proteins also help with the structure of a cell. Tissues and organs in your body depend on proteins to function normally.

You should note that proteins have different functions in the body. The main functions performed by proteins include:

  • Antibody activity to help protect your body against bacteria, viruses, and other pathogens.
  • To act as messengers, which help hormones communicate with cells and to process signals that are transmitted between various cells in your body.
  • As a structural component, proteins help the body move and ensure tissue can maintain its appropriate structure.
  • As a storage unit, proteins allow atoms and smaller molecules in your body to be stored and even transported to other areas of our body.
  • Some proteins act as enzymes, which are critical to the chemical reactions that occur in cells.
When it comes to your muscles, in particular, protein helps with the process of regenerating your muscle tissue after it has been damaged. Remember, those muscle fibers are damaged during exercise – especially when you perform heavy weight lifting. These muscle fibers are repaired, and they regenerate – that is how your muscles grow larger.

While protein is critical when it comes to muscle growth, as well as weight gain – there is one thing that you do need to take note of. Too much protein can be a disadvantage. You need to find the right balance.

When the amount of protein you consume exceeds a 30% value of your daily calories, then this micronutrient may actually become harmful to your body.

One report explains that an excessive amount of protein may put excess stress on various systems in the human body. Furthermore, consuming too much protein can also lead to the accumulation of ketones in the kidneys – and this can damage the body’s two filters (the kidneys).

With this in mind, it can still be difficult to give your body enough protein on a daily basis to support your strength in the gym, while also allowing muscle tissue to regenerate faster and more effectively. This is why many people decide to opt for a supplement that will give them access to more protein.

Choosing The Best Whey Protein For Weight Gain

Whey protein powder continues to be one of the most popular supplements used by people who want to gain weight – particularly those who wish to gain more muscle mass.

This has led many companies to produce their own protein powder. Sure, this might mean a larger variety of products for you to choose from – but when the ingredient list and claims become too similar, you will quickly find yourself confused with which product to choose.

There are some effective and high-quality whey protein powder products on the market. At the same time, however, some of these products may end up being a complete waste of your money.

With knowledge about specific factors to look at when you decide to buy a whey protein powder, you can ensure the product you buy will be safe, effective, and give you more value for your money.

We share a couple of the most important things you should look at when filtering through whey protein powder products below:

  • Ingredient List: Start your filtering process by looking at the ingredient lists of the whey protein powder. The shorter the list of ingredients, the better. Those products that have a significant number of ingredients in the powder tend to use a lot of fillers. This is something you want to avoid, as the protein powder will not be as pure or effective.
  • Protein Dose: Make sure each serving of the protein powder you want to buy can give you an adequate dose of this micronutrient. It is generally advised to opt for a whey protein powder that delivers more than 20 grams of protein per serving. You should, however, also ensure the product does not contain too much protein, as this could be damaging to your body.
  • Whey Protein Type: You also need to consider the type of whey protein that you are going to buy. There are two main categories in which a whey protein supplement can fall. These generally include isolates and concentrates. You should consider opting for an isolate for a more potent product. A whey protein isolate powder will contain 90% or higher protein content in the supplement.
  • Flavor: While choosing a flavor can be useful, many of the flavored varieties of whey protein powder will contain added sugars. Consider opting for an unflavoured option instead. You can then experiment with your own flavoring agents. Consider adding some cocoa powder for a cholate taste. You can also experiment with vanilla extract or another flavoring agent that is not loaded with sugar.
  • Artificial Ingredients: Always try to get your hands on a whey protein powder that does not contain any type of artificial ingredients. Many companies tend to add certain artificial ingredients to these supplements. These artificial ingredients often include the use of sweeteners, with the goal of adding a more pleasant taste to the product. Avoid products that contain ingredients like dextrins, maltodextrins, sucrose, sugar alcohols, or other types of sweeteners.
  • Price: Whey protein powder supplements are generally not too expensive. They tend to be more affordable than some of the alternative muscle building supplements that you get to choose from – such as mass gainers. Thus, you should always make sure you are not paying more than you should. Look at some of the best options on the market and compare their prices, while also taking into account the number of servings contained in each container. This will help you determine which product can give you better value for the money you will be spending.

Other Ways To Boost Your Protein Intake

Now that we have looked at some of the most effective supplements you can buy when trying to increase your intake of protein; we should also note that you can boost your protein intake through your diet as well. There are many foods that can be included in your daily diet to give you a higher dose of protein.

You should consider creating a good balance between food and supplements. Try to get some protein from your daily meals. The protein that you may still lack from your diet can then be fulfilled with the use of a whey protein powder product.

Try to add some of these foods to your daily diet to give you a boost in protein:

  • Boiled eggs
  • Peanut butter
  • Cheese
  • Greek yogurt
  • Cottage cheese
  • Pumpkin seeds
  • Chia seeds
  • Lentils
  • Flex seeds
  • Quinoa
  • Bulgur wheat
  • Tuna
  • Mackerel
  • Salmon
  • Turkey
  • Beef jerky
  • Chicken
  • Lean beef
  • Avocado
  • Almonds
  • Tofu

The list contains quite a few examples – be sure to add a combination of these foods to your daily meals. Some of them can also be used as snacks – consider packing some almonds in a bag and snack on them during the day.
