Top 8 Mass Gainer Supplements On The Market


See which products are best for aiding in your weight gain efforts!

Weight gainer supplements are a special kind of nutritional aid geared toward the “hard gainer” population who just can’t seem to put on size.

Now, we know it takes an excess of calories to gain one pound of bodyweight. More specifically, about 3,500 calories to be in a positive energy balance (although recent research varies with this number). But even if you’re skinny, it doesn’t mean you should eat everything in sight. (1)

However, you simply can’t eat chicken breast and rice all day while expecting to make continued gains after a certain point. So, that’s where supplementation and liquid calories provide value for the typical skinny guy or gal with a fast metabolism.

And we put together a quality list of mass gainers to help you reach your goals effectively…

What Is a Mass Gainer?

Mass gainers are calorically dense nutritional aids used for weight gain. They’re geared toward lifters who are looking to utilize the nutrients to put on muscle mass. But they could technically beneficial for people who are severely underweight (minus the added creatine and performance aids).

However, the majority of products are formulated with high protein and carbohydrates to fuel your training and supply muscle tissue with building blocks for growth.

So, you’d really want to be training hard to utilize these calories for muscle mass gains rather than just as a meal replacement for a sedentary individual.

These mass gainers also supply a decent amount of vitamins and minerals which is a nice addition for overall health support. Plus, some products contain creatine which we know is a safe and proven performance aid.

Now, people with a fast metabolism will tend to use these products in hopes of putting on size but the daily caloric intake must be consistently positive to achieve this. And food should always make up the majority of calories with mass gainers to supplement the remaining calories for the day.

Mass Gainer Benefits

Several studies have concluded that there are benefits for consuming a multi-ingredient nutritional supplement.

In fact, 35 trials which involved 1,387 participants showed significant improvements in fat-free mass and strength with multi-ingredient supplementation either containing creatine or Vitamin D. (7).

But many people use mass gainers to put on size without having to struggle through eating all of their calories from food sources (the struggle is real). And as a result, strength and power increases as bodyweight and performance improvements are correlated to a large degree. (8)

Quality mass gainers supply plenty of fast and slow-digesting proteins in a blend which is very effective for putting on lean muscle mass. And the abundance of carbs plus fats supply a good source of energy in which you can sustain your intense workouts for prolonged durations.

How Many Servings Should I Take?

This depends on how many calories you need to consume to gain weight at a rate of a few pounds per month. But then your genetics and training will also determine how much “good” weight you’ll gain. So, there’s no universal answer to this question.

However, you should only use a mass gainer to fill in what you cannot get from a primarily whole food diet.

And if you need to track your macros then you’ll have to do so accordingly by measuring the serving sizes.

Protein requirements

The amount you need will depend on your body weight, activity levels, and age. But generally, 1.6-2.2kg/day is an ideal range for muscle hypertrophy. (9)

To build muscle, you should be getting sufficient amounts per each meal. And many weight gainers supply rather high amounts so splitting servings is a good idea in many instances.

Carb and fats requirements

For size gains, carbs should be on the higher end to replenish lost glycogen, again, if you’re not following a keto diet (high fat, low carbs). But fat is necessary as an energy source as well.

Carbs should usually make up half of your daily caloric intake and fat 20-35 percent with protein taking up the remaining percentage. (10)

When Should I Take A Serving Of Mass Gainer?

You can have a serving any time of the day… but, according to research the best time to consume a whey protein is within three hours following resistance training. The reason is that anabolism is increased within this time frame (peak of 45-90 minutes) and muscle protein synthesis drops back down to baseline levels past the three-hour window. (11)

But carbohydrates like maltodextrin (added to many mass gainers mentioned) and glucose are also necessary in combination with protein to maximize this process. And essential amino acids which are naturally occurring in most whey protein supplements are also very necessary for optimum protein synthesis. (11)

But having a shake any time of the day in addition to your meals will be beneficial for maintaining a caloric surplus.

Are Mass Gainers Safe?

The ingredients in these mass gainers are safe for most users. But some products contain artificial ingredients, dairy, added sugars, and additional ingredients which some people have sensitivities to. So, people with blood sugar issues or sensitivities to certain foods should definitely be careful to read the labels before consuming any nutritional supplements.

Now, many supplements have added sweeteners like sucralose and acesulfame potassium but these are actually considered safe for daily consumption according to the most recent research on the substances.

Large studies looking at people have now provided strong evidence that artificial sweeteners are safe for humans,” according to Cancer Research UK.

And in the U.K. these sweeteners and all others must undergo an extensive process by the European Food Safety Authority (EFSA) to ensure safety for normal consumption. These sweeteners are also beneficial and safe for people who need to be extra mindful of their blood sugar levels. (3)

But too much of anything is not ideal for maintaining optimal health and that’s why it’s important to stay within your recommended caloric and macronutrient range.

Mass Gainers Are Useful Nutritional Aids

Mass gainers aren’t ideal for everyone but they have a purpose in a diet with the goal of adding lean body mass and increasing strength.

But quality does matter and although some most of our selections aren’t bare minimum where ingredients are concerned; they are a quality source of protein with additional ingredients that are safe and effective for making those much-desired gains.

So, choose a mass gainer that gives you the best value overall for what you’re looking to achieve!
