Mass Gainer Explained

The 10 Best Mass Gainer Supplements To Buy

Firstly, what is mass gainer exactly? If you know what mass gainer is, go ahead and skip this part. But if you are new to mass gainer supplements, keep on reading to find out everything you need to know before you buy.

Put simply, mass gainer is a dietary supplement in powder form that is used to support weight gain and muscle growth.

Bodybuilders use it to “bulk”, but it can also be used by “hard gainers” or anyone who finds it hard to gain weight due to their metabolism.

The main ingredients of main gainer supplements are protein and carbohydrates with a high amount of calories. So, taking mass gainer promotes muscle growth and fat gain simultaneously.

In a typical mass gainer serving (one heaped powder scoop), you can expect to get, in general, up to 50 grams of protein and around 250 grams of carbs with a total calorie intake of between 1000 and 1500 calories.

Mass gainer comes in a range of flavors, sometimes with added ingredients (additional amino acids, BCAAs, vitamins, and minerals), with options that are vegan-friendly and gluten-free.

It is widely available from fitness stores, supplement stores, and online sellers.

Mass Gainer Pros

What are the pros of taking mass gainer?

The obvious advantage of taking mass gainer is that it is an effective method for putting on mass (weight) quickly.

The high calorie, protein, and carbohydrate content promotes weight gain across the board, ideal for bodybuilders and anyone who struggles with weight gain.

Another advantage is that it is convenient and easy to take. As a powder supplement, you simply mix it with water and/or milk, and then drink it.

It is also affordable for most people and generally safe to take in its recommended amount.

Due to its ingredients, mass gainer can even support muscle recovery and repair, boost general energy levels, and improve workout performance.

Mass Gainer Cons

What are the disadvantages of taking mass gainer?

The clear disadvantage of mass gainer is that it supports muscle and fat growth simultaneously. That said, this is not a problem if that is your goal.

But if you are looking to build muscle mass while keeping your carb/calorie intake low, you will be better off looking elsewhere.

Another disadvantage is that it can pose the risk of side effects.

Although generally considered not serious or harmful, the side effects of mass gainer may include bloating, digestive problems, loss of appetite, flatulence, and stomach cramps.

More serious side effects are kidney damage and liver damage.

But, like any supplement or medication, mass gainer should be taken sensibly in its recommended amount.

This promotes safe usage and reduces the risk of any possible side effects.

Buyer’s Guide

Mass Gainer Ingredients

Before buying any mass gainer supplement, the most important thing to check is the ingredients.

Always check the protein, carbohydrate, and calorie content, as these are the key ingredients of any mass gainer.

In general, mass gainers will provide around 50 grams of protein, around 250 grams of carbs, and between 1000 and 1500 calories (per serving).

If desired, it’s also worth checking if the mass gainer includes BCAAs/other amino acids, creatine, and vitamins and minerals.

Mass Gainer Flavor

Like whey protein and casein, mass gainer powder comes in a range of flavors that you mix with water and/or milk before drinking.

This is important as mass gainers contain multiple servings, so it’s worth making sure that you will enjoy the flavor.

Mass gainer flavors can include chocolate, banana, vanilla, cookies and cream, strawberry milkshake, chocolate peanut butter, and more, although this will depend on the manufacturer.

Unflavored mass gainer is also available if you prefer to blend with other ingredients.

Frequently Asked Questions

What is Better Whey Protein or Mass Gainer?

Whey protein is used to increase dietary protein intake and therefore promote muscle growth. Mass gainer, on the other hand, promotes weight gain overall with a high concentration of protein, carbohydrates, and calories.

Which is better will depend on your goals. If you just want to put on more muscle, whey protein is the better supplement.

If you want to get bigger overall or “bulk”, mass gainer will help you to gain weight by increasing your general calorie, carb, and protein intake.

Is Mass Gainer Dirty Bulk?

A common misconception about mass gainer is that it is “dirty bulking”. But taking mass gainer and dirty bulking are not the same thing.

Mass gainer promotes weight gain (fat gain and muscle gain) through a high intake of carbs, calories, and protein in supplement form.

Dirty bulking, on the other hand, refers to eating any kind of food – including fast food, junk food, and refined foods – for fast weight gain results. This method is not healthy, hence the term “dirty bulking”.

Is Mass Gainer Harmful?

Mass gainer is not harmful in any way unless taken excessively.

To make sure you do not experience any side effects when taking mass gainer, always supplement it in its recommended amount as per the manufacturer’s recommendation.

Possible side effects of taking mass gainer, however, may include bloating, flatulence, digestive problems, and diarrhea.

It’s also important to remember that mass gainer should be used for supplementation only and never as a meal spa0fd-20nt.
