No one ever said gaining lean muscle mass was easy. Fortunately, mass gainer supplements exist. Typically in powder form, a mass gainer help you bulk up and gain more muscle than you normally would.

If you haven’t yet noticed, there are quite a few mass gainers available online and in stores. Trying to find the best mass gainer takes a lot of looking through supplements.

New Generation Fitness saves you time and energy with our list of the best mass gainers of 2023.

You’ll also learn about what mass gainers are made of, how they work, and answers to commonly asked questions about these supplements.

Do you not have time to read the list? That’s okay – here’s a super quick list of the best mass gainer supplements:

What is a mass gainer supplement?

lean muscle mass

You can hear these supplements referred to by many names, including mass gainer protein powder, mass gainers, and mass gaining supplements.

However you refer to these supplements, they all can help with the same benefit: gaining more mass. These supplements are typically high in calories and protein.

People typically mix mass gainers with milk, meaning these supplements are often in powder form. After mixing the flavored powder with milk, you have a drink to help you gain weight.

How do mass gainers help you gain lean muscle mass?

mass gainer protein powder

The main reason that quality mass gainers help people gain weight involves the ingredients in these supplements.

Typically, a mass gainer contains ingredients, including protein, fat, and carbohydrates. So, drinking a beverage containing mass gainer powder adds more protein, calories, and fat to your diet.

Keep in mind that¬†mass gainers aren’t capable of performing magic.¬†You’ll still need to lift weights if you want to gain muscle mass. As is the case with doing cardiovascular exercise, like spending time on a treadmill, if you want to lose weight effectively.

The top-rated mass gainer supplements of 2023

As mentioned earlier, there is a ton of mass gainers on the market. Don’t waste your time with ineffective weight gainer supplements. Here’s a researched list of the best mass gainer supplements.

To come up with this list, the other members of the New Generation Fitness team and I listed our personal favorite weight gainers. We also checked on popular websites, including Amazon and Bodybuilding.com, to find the top-rated and most popular mass gainers.

1. Optimum Nutrition Serious Mass: Best overall mass gainer

A popular company in the supplement world is Optimum Nutrition. You might know this company from its protein powder. However, it also makes a popular mass gainer product called Serious Mass.

Every two-scoop serving of this mass gainer delivers 50 grams of protein, 1,250 calories, and over 250 grams of carbohydrates. Serious Mass is available in several flavors, including banana, chocolate, strawberry, vanilla, and chocolate peanut butter.

One reason why this supplement is so popular is that it’s effective. The ingredients in this product will help improve muscle protein synthesis and assist you with gaining weight.

Optimum Nutrition Serious Mass is also a great-tasting supplement. I’ve tried a few of this supplement’s flavors and never noticed a chalky or otherwise unpleasant taste.

But consuming so many calories at once isn’t easy on everyone’s stomach. So, as Optimum recommends, it’s best to start with one scoop of this lean mass gainer before having a full two-scoop serving.

2. Beverly International Mass Maker Ultra: Lowest-priced option

Another popular option if you want more muscle mass comes from Beverly International. This company’s mass gainer contains 25 grams of protein per serving with only six grams of total sugar. Mass Maker Ultra also contains 390 calories per serving.

One of the main benefits of this mass gainer, among others, is that it’s easy on the stomach. Notable reviewers mention that Mass Maker Ultra doesn’t cause bloating or stomach discomfort.

You’ll also find that this mass gainer features a blend of four protein sources. It also contains high-quality, healthy fats from its medium-chain triglycerides and coconut oil.

Compared to most mass gainers, this supplement is slightly cheaper than other popular picks. This mass gainer is available in either a chocolate or vanilla flavor.

3. Dymatize Super Mass Gainer: Best nutrition profile

Dymatize is a well-known supplement company. So, it makes sense that this company’s Super Mass Gainer would make a list of the best mass gainers.

This supplement can help you gain muscle mass with 52 grams of protein and 245 grams of carbohydrates per serving. You’ll also get 14 different vitamins and minerals in every serving of this muscle growth supplement.

Super Mass Gainer also packs over 10 grams of non-essential and essential amino acids as well as 1,280 calories per serving. You’ll find amino acids in various meats and dairy products. But with this supplement, you don’t have to worry about getting your amino acids from other sources.

Another reason this supplement is one of the greatest mass gainers is that it contains fast and slow-absorbing protein. Consuming these types of proteins means you’re building muscle for a longer time than with non-time-released proteins.

Unfortunately, this supplement isn’t the best mass gainer if you like a large flavor selection – Super Mass Gainer is only available in chocolate and vanilla flavors.

4. Naked Mass Vegan Weight Gainer: Best vegan option

By far, the most preferred vegan mass gainer comes to us from Naked Nutrition. This mass gainer gets its carbs and protein from yellow peas and organic brown rice. It’s also notable for not including any artificial flavors, colors, or sweeteners.

This plant-based mass gainer contains 1,230 calories per serving. Each serving also includes 50 grams of protein for ample muscle growth. Naked Mass also comes with 252 grams of complex carbohydrates in each serving.

Another factor making Naked Mass the best mass gainer for vegans is its inclusion of calcium, iron, and potassium for maximum health support. For some people, the thought of drinking protein from peas might not sound appealing. But I promise that you can’t taste any peas in this mass gainer.

Whether you’re a vegan or someone who is allergic to whey protein concentrate, Naked Mass is a great-tasting mass gainer that is full of carbohydrates and protein. This company’s mass gainers are available in chocolate or vanilla flavors.

5. Vitol Russian Bear 5000: Top-rated mass gainer

If I could award the “best-named supplement,” I’d definitely give it to this pick: Vitol Russian Bear 5000 Weight Gainer. That’s like the name of a supplement you’d see in a comic book or something. On paper, this supplement might sound like a gimmicky muscle mass product.

In reality, Vitol Russian Bear 5000 is a top-tier mass gainer packed with plenty of calories and protein per serving. However, the way Vitol recommends you take this supplement is a little different from what you’re used to.

Vitol recommends mixing five scoops of this supplement into a gallon of milk and drinking it throughout the course of the day. With these five scoops alone (without milk) containing 2,600 calories, you definitely don’t want to try chugging this one.

Russian Bear 3000 also contains medium-chain triglycerides, which can’t store themselves as body fat. That means these triglycerides give you more natural energy, which is especially useful when you’re completing workouts.

6. BSN True Mass

Another great-tasting and popular mass gainer comes from a company called BSN. You can find this company’s signature red supplement containers both in stores and online.

True Mass contains BSN’s premium protein powder to help improve overall mass gain. It also includes a two-to-one ratio of carbohydrates to protein to support lean muscle and weight gain.

Each serving of this weight gainer contains about 50 grams of protein and about 90 grams of carbohydrates per serving. That leaves True Mass containing about 710 calories in each serving.

True Mass is available in four flavors, chocolate milkshake, cookies and cream, vanilla ice cream, and strawberry.

7. MHP Up Your Mass XXXL

MHP Up Your Mass XXXL contains a blend of five sources of protein, totaling up to 50 grams of protein in each serving to help with muscle growth. This mass gainer contains 1,350 calories per serving.

This company’s mass gainers are available in three flavors:

This was one of the first mass gainers I’ve ever tried. If you want a personal tip, I’d recommend using skim milk and a lot of it per serving (1.5 to 2 times more than what it recommends). If not, you’re going to have a mega-thick drink, which is fine if that’s what you prefer. From a texture standpoint, I can’t do drinks as thick as cake batter.

Up Your Mass also contains 11 grams of branched-chain amino acids (BCAAs) in each serving. These BCAAs are valine, isoleucine, and others that help improve your muscle protein synthesis.

Do you have questions about mass gainers? Here are answers to the most common questions New Generation Fitness receives about supplements that help with weight gain.

Can drinking a mass gainer supplement make you fat?

As is the case with anything consumed frequently, a mass gainer can have the potential to make you fat. With that said, these supplements are for people wanting to gain weight and muscle mass.

Being on a workout program helps you build muscle. If you lift weights and take a mass gainer supplement, you’ll gain less fat because you’re working on building muscle.

Is it safe to use mass gainer protein powder every day?

Yes. Whether you prefer whey protein concentrate or whey protein isolate in your weight gainer supplements, it’s safe to drink these supplements every day.

However, most people would recommend taking at least a small break in between working so hard to pack on calories and gain mass. Instead of drinking a weight gainer supplement daily for months, you can also switch things up by drinking a protein shake.

Will mass gainers cause side effects?

whey protein concentrate

Yes, they can. That’s not because mass gainer protein powders are dangerous – they’re not. Instead, the side effects involve how well your digestive system handles protein powders and a lot of calories at once.
