How We Rank the Best Mass Gainers for Building Muscle Mass?

Mass gainers are a particularly difficult supplement to understand since consumers’ demands might be shockingly diverse. These are some things that we take into account to choose the best mass gainer supplements in the supplement industry.


This list includes a broad variety of pricing and tub sizes. Some of these selections are enormous, low-cost tubs of simple mass gainer, while others are tiny, more costly canisters of more complex mass gainer.

We’ve included an option at a sensible price range here to meet your demands, whether you’re looking for a simple mass gainer that concentrates on macros or a more sophisticated mass gainer that also integrates micronutrients.

No matter how much you’re spending on these picks, they’ll be worth your time.

Protein vs Carbs

The protein-to-carbohydrate ratio varies per product, and the ratio desired by consumers varies as well. Some people prefer a boost of protein and carbohydrates after a workout, while others prefer protein and fewer carbs.


Vitamins and minerals are both examples of micronutrients. Some people like to take these nutrients with their mass gainers, while others do not.

To accommodate both sorts of consumers, we’ve given alternatives with and without extra micronutrients, such as creatine monohydrate or digestive enzymes.

Sweeteners for Best Taste

Some folks choose to stay away from artificial sweeteners. Though there is no conclusive proof that they would damage you, we have stated whether or not a mass gainer includes these substances for individuals who choose to avoid them in favor of natural sweeteners.

If this isn’t a concern for you, we’ve included supplements on this list that do include some artificial sweeteners.


These are some of the most astute and forthright assessments of any product. However, before you form an opinion, be sure to read various reviews.

Remember that some individuals just write reviews for the purpose of writing, while others provide misleading information.

How to Choose the Best Mass Gainer Supplements?

Because mass gainers can be used for a variety of purposes such as gaining muscle mass, filling dietary gaps, calorie intake, and so on. You’ll want to consider a few factors, as well as how they may interact with your workout routine and lifestyle, before adding a mass gainer to your supplement stack.

Protein-to-Carbohydrate Ratio

Protein-to-carbohydrate ratios in mass gainers vary from different ranges. Because they offer fewer carbohydrates per serving, the lower ratios will be great for people looking to gain lean muscle.

Athletes attempting to bulk or increase calories and carbohydrates to their diet will benefit from those closer to the one-to-five ratio.

Before you pick a mass gainer based only on calorie count, consider how the protein to carb ratio will fit into your lifestyle and training plan.


The caloric content of bulk gainers varies greatly. There are bulk gainers with as little as 200 calories and others with over 1,000 calories.

If you want to grow lean muscle mass, you should choose a food with a low-calorie count but a high protein to carb ratio. Or if you want to bulk and add overall mass, a higher calorie option with more carbohydrates and/or fats may be a better alternative for you.


Many mass gainers include vitamins and minerals in their formulations. From creatine to digestive enzymes, these supplements are designed to help with other elements of your health, such as digestion and energy, rather than merely supplementing certain macronutrients.

However, other individuals may not value this and prefer a simpler formula that just supplies the calories, carbohydrates, and proteins required to maintain and increase muscle development.

Ingredients to Avoid

If you are lactose sensitive, you should choose vegan kinds; they are less likely to contain lactose, but always check the label before purchasing.

Aside from oats and protein, it is also a good idea to look at what additional supplements have been added to the mix.

Mafuctarurer Per Se

Decent mass gainers are one that is made at a GMP-certified plant in the United States.

Calories and Serving Size

Because the mass gainers described above range from 510 to 1,360 calories per serving, it’s a good idea to think about your objectives and how many more calories you’d want to add to your day.

Another crucial factor to consider for other mass gainers is the serving size. While some weight gainer supplements are more concentrated than others, others need up to 4 scoops of powder per serving.

Conclusion: Best Mass Gainer Supplement

When it’s difficult to obtain more calories via solid meals alone, mass and weight gainer supplements might be a terrific approach to boost muscle development.

Mass gainers are not all the same, and it is always a good idea to research the contents and nutritional facts before committing to one.

Are you a hard gainer or ectomorph trying to bulk up and add muscle to your frame? If that’s the case, Optimum Nutrition’s Serious Mass is the supplement for you.

It’s packed with great calories, protein, carbohydrates, and other muscle-developing ingredients, and it’s a terrific value for money. It’s also great for individuals who struggle to get a full meal in at every sitting.
