Weight loss is the most common health goal generally speaking, but what about those of us looking put on weight?

Jump Ahead to the Best Mass Gainers

More often than not, especially if you have a thin build naturally, that can be just as difficult as losing weight. It takes a regimented and disciplined approach to training, and it also requires us to eat massive amounts of food to stay in caloric surplus, or bringing in more calories than we expend. In addition, unless adding fat is your goal, the quality of those calories is crucial so we have to eat massive amounts of good, quality food to increase our muscle mass. Generally speaking, this is much easier said than done.

That is where a mass gainer comes into play and can be an incredibly useful supplement. Mass gainers are popular and safe supplement options that deliver a large number of calories and nutrients without adding junk to your diet, helping to stay in a caloric surplus and pack on muscle mass. They can be simply mixed with water or blended in to make shakes and are an incredibly useful and effective supplement choice for getting bigger and stronger! In this break down we’ll cover what goes into mass gainers, how to make the best purchase decisions and our ten highest recommended products.

What Are Weight Gainers?

Like protein powders, weight gainers deliver easily digestible protein, but they also contain carbs and sugars that usually provide around 700 – 1,000 calories or more per serving.

Most weight gainers come in a powdered form that’s designed to blend with liquids to create a shake that’s easy to drink. However, some weight gainers can also be found in pill form.

First and foremost, calories. Calories are essentially a unit of how much energy or nutrient we are putting into our body; in order to gain weight, the goal is to train effectively and consume enough calories to achieve a caloric surplus, or take in more calories than we burn. This requires in many cases far more calories per day than the standard recommendation, and the calorie count of a mass gainer product is particularly important.

Mass gainers include a wide variety of potential ingredients from a diverse range of categories. The first primary breakdown to look at with a mass gainer is the macronutrients. Macronutrients, classified as protein, carbohydrates, and fats are the three broad categories of nutrition we take in that our body uses for energy. Generally, if we are looking to add muscle mass we primarily want protein but will also want carbohydrates for the additional carbs and energy. In mass gainers, you’ll find various protein sources such as whey or casein. Carbs come from a variety of sources and are in most mass gainers, while fats generally are not present or a very low portion of the macronutrient blend.

Mass gainers also tend to contain other supplement that assist with muscle growth. Many products will contain smaller amounts of creatine, amino acids and the like to assist with training muscle development, helping to only add mass but also improve your actual strength and performance.

Finally, some mass gainers will contain various vitamins, minerals, or additional ingredients. One example to look for is fiber, with the amount of nutrients and ingredients the body has to process when trying to put on mass, fiber is an important ingredient to have to help the digestive effectively process all of the incoming nutrients.

Common Ingredients of Weight Gainers

Like all supplements, weight gainers vary in their ingredients and proportions, and manufacturers often promote their signature proprietary formulas and special ingredients.
Consumers should, however, be wary of extraordinary claims or ingredients that they aren’t familiar with or when they don’t understand what effects the ingredients might produce.
Our weight gainer is accompanied with a fully transparent ingredient breakdown as well as information on what each ingredient is and does within the body.
The most common ingredients of weight gainers include:


The protein component of weight gainers can come from many sources including wheymilk protein isolatewhey isolate, egg albumen, calcium caseinate and whole egg powder. The biological value of protein, or BV, describes how easily protein components are absorbed into the bloodstream where they can be used to provide energy and build muscle.


Carbohydrates can spike insulin levels, but unlike with sugar consumption, the process is safer, more controlled and beneficial for building muscle and gaining weight safely. According to the fact sheets on supplements, consuming carbohydrates is a safer way to gain weight for those people who are looking to do so.

Carbs can also cause unwanted weight gain, but it’s a great solution for those who really need to or are looking to gain weight, build muscle or maximize athletic performance. The U.S. military generally supports consuming more carbs for those recruits who are trying to gain weight and muscle fast.


The natural amino acid creatine, which is found in meat and fish, is also produced in the human body. Bodybuilders and health advocates spend millions of dollars annually on creatine supplements, which numerous studies and tests have shown to improve athletic performance and increase muscle mass when used properly in conjunction with bodybuilding, exercising and strength training.


L-glutamine, another critical amino acid, speeds muscle recovery after a hard workout. The compound also helps to fight diseases and strengthen the immune system. Important university research and trials show that glutamine helps to remove excess ammonia in the body that builds up after exercise.

Although this amino acid is the most common in the body, high levels of stress can cause the release of cortisol, which reduces glutamine levels. Ensuring enough of the acid after a workout generates faster recovery rates and helps people to stay hydrated in addition to glutamine’s long-term benefits of strengthening immunity and aiding brain activity and digestion.


Too much sugar can prove dangerous because it can trigger an insulin spike. According to newly drafted guidelines of the World Health Organization, even athletes should get no more than 10 percent of their calories from sugar, which translates to about 25 grams for an average adult.

Too much sugar can trigger adult onset diabetes, insulin resistance, liver failure, kidney disease and high blood pressure. It’s safest to avoid too much glucose and fructose in health gainers; the protein, carbs and beneficial amino acids can encourage enough muscle-building weight gain to satisfy most supplement users.That’s healthier and safer than consuming supplements that contain excessive amounts of sugar.

Fiber and Digestive Aids

Supplements aren’t designed to replace eating healthy food, but for some people who can’t consume enough calories to fuel their high rates of metabolism, weight gainers can prove extraordinarily useful.

However, getting calories from supplements creates another potential risk that healthy nutrition would normally prevent–digestive distress caused by lack of fiber in the diet. Harvard nutritional studies show that getting more protein and fiber in the diet improves body composition, satisfies hunger more effectively and generates a higher thermic effect from the combustion of nutrients.

That’s why fiber and protein are prime ingredients for weight gainers for people who don’t eat enough. The fiber might not be as essential for those who already eat a full diet.

Primarily used by athletes and bodybuilders, weight gainers can be used by anyone who wants to gain weight. This includes people who are recovering from health-related weight loss, those with high metabolic rates and thin people who just want to put on a few pounds.

How Weight Gainers Work

The science of gaining or losing weight isn’t difficult to understand–simple math and science determine whether a person gains or loses weight. Calories are units of thermal energy, and food (or supplements) are metabolized to generate this energy. One gram of a given substance, however, varies in how many calories it can generate. For example, one gram of protein generates four calories of energy. One gram of fat generates nine calories.

Each person burns a different number of calories based on his or her weight, metabolic rate, height, activity level and other factors. The basal metabolic rate, or BMR, is the sum of the energy needs of all bodily functions. This figure also varies based on the level of activity that each person maintains throughout the day. It takes 3,500 calories to gain (or lose) one pound of body weight. That means adding 500 calories per day to gain one pound per week if the BMR needs are otherwise met with normal eating habits.

Weight gainers usually contain highly digestible protein, carbs and nutrients that get into the blood quickly. Mixed with water or other liquids, the powdered form is easy to absorb. However, blending the powder well is critical to prevent lumps that could remain in the digestive tract for long periods.

Once these nutrients are in the blood, they’re available to fuel energy during a workout, break down and rebuild muscle and help athletes to recover after their workouts or exercise for longer periods than they could without supplement-enhanced energy.

Benefits of Weight Gainers

The benefits of taking weight gainer supplements depend on why each person wants to gain weight. Most nutritional, medical, scientific and university studies agree on one issue–the safest method of gaining weight is to do so gradually by increasing caloric intake naturally with increased food consumption.

However, that doesn’t always work for athletes who need to build strength in a hurry, people with high metabolic rates and those who can’t seem to eat enough to gain weight.

The benefits of taking weight gainers–according to most users–include:

  • Meeting normal or extreme daily calorie requirements
  • Getting essential nutrients for extreme athletic and bodybuilding workouts
  • Managing different caloric needs to build muscle more effectively
  • (on and off days are generally thought to be more effective for building muscle)
  • Gaining weight from muscle while appearing leaner and more fit
  • Recovering more quickly after workouts
  • Getting access to different flavors and varieties to change up the daily workout routine
  • Fostering better internal health by taking supplements with added fiber and essential vitamins and minerals

Who Can Benefit from Mass Gainers?

Mass gaining supplements work best for those people who require high-calorie diets to fuel workouts, gain muscle or recover weight lost during an illness. Those who participate in bodybuilding competitions are the most common users of weight gainers, but anyone who needs to gain weight could be a good candidate for taking weight gainer supplements.

It’s important to study the ingredients and see if they match any user’s weight-gaining goals. The ingredient mixture should be researched for possible interactions with medications or existing health disorders.

Athletes who want to build muscle, increase their workout stamina, recover faster after exercise or shape their bodies could find the right weight gainer supplement a great resource for meeting their fitness or weight goals. However, it’s important to remember that these weight gainers are dietary supplements and not replacements for sound nutrition and work hand in hand with consistent exercise.

Metabolism, body type, and genetics play major roles in gaining and losing weight. Gaining weight can be hard for some people–just as hard as losing it is for most people. Genetics, small builds and active lifestyles make it hard for some people to eat enough to gain weight. Weight gainers can be extremely helpful for those people who just can’t otherwise gain weight.

In many sports, fast weight gain (or loss) can be critical for qualifying for certain weight classes; fore example in wrestling, boxing, martial arts and other combat sports. Taking weight gainers for a few days can help certain athletes qualify for a higher weight class, which could be strategically desirable for the team or individual.

Regardless of the reason for taking a weight gainer supplement, people should always consult their physicians before trying to gain weight for any reason. Supplement formulas could interact negatively with medicines, trigger allergic reactions or exacerbate certain medical conditions. Gaining weight could also trigger other health issues such as high blood pressure, obesity, cardiovascular disease, diabetes and other conditions.

How to Use Weight Gainers

Weight gainers come in flavored powders and pills, but mixing a shake is the easiest way to get fast results. Athletes can use weight gainers–along with adequate nutrition–to trigger muscle-building efforts and increase stamina and endurance.

Drinking a shake prior to a workout helps to ensure an adequate supply of nutrients for tearing down and rebuilding muscle. Depending on a given supplement’s unique formula, taking a weight gainer shake before or after a workout can help athletes recover more quickly, exercise for longer periods and gain lean muscle while losing fat.

It’s important to consult a trainer, coach or physician before using a mass gainer product. Find out what’s in each supplement before trying it. Mixing the product with milk works well because milk adds healthful ingredients while preventing stomach upsets in most people. Determining how many scoops to add depends on each person’s weight-gaining goals and training strategy.

Those who just want to gain weight usually take their weight gainers as snacks between meals. This approach ensures that a supplement’s users get adequate nutrients without feeling full or bloated.

Safety Considerations of Using Any Dietary Supplements

Regardless of a supplement’s formulation, all supplements carry the risks of side effects, interactions with prescription and over-the-counter medications, as well as unethical practices such as fraudulent health claims by manufacturers and distributors and adulterated formulations.

Unlike drugs, supplements aren’t regulated as thoroughly by the FDA. That doesn’t mean dietary supplements can’t and don’t carry any health risks when used irresponsibly. A Class I recall by the FDA was ordered for 237 dietary supplements between January of 2004 and December of 2012 because of the risk that these formulations could cause or exacerbate serious health issues.

Most recalls were and are for weight-loss supplements and products that contain ingredients that the FDA classifies as drugs. That’s why it’s so important for supplement users to research the ingredients of any supplement formula and check with their doctors and pharmacists before beginning a supplementation regimen.

Weight gainers seldom generate health risks when used as directed for moderate weight gain, but the altered behavior that supplementation could facilitate—such as longer workouts and increased weight gain—could pose health risks for some people.

Side Effects of Mass Gainers

The side effects of mass gainers are rarely an issue if you follow the basic recommended dosage from a given product. However, if you increase the dosage you may experience some side effects. In addition, many mass gainer products come with additional ingredients or may be paired with other compounds for additional effects, thus side effects related to those ingredients can come up as well. When in doubt or if you are new to mass gainer supplements, make sure to consult with your medical professional for advice on the best product.

The most common side effect will generally result from taking a mass gainer product is putting on unwanted weight, namely fat. Due to the high number of calories and carbs your body is taking on, if your training is not at a high enough intensity or your diet is not effective, you may see fat increase as well as muscle mass. This is commonly an unwanted side effect, but easily remedied by lowering your intake or improving your training and diet. In rare cases mass gainer can be associated with other issues such as Adonis complex, but as stated previously when taking the appropriate dosage, it is fairly benign.

Things to Consider When Buying

When choosing a mass gainer there are a variety of factors to take into account. Your personal preferences will play a major part in finding the right selection for you, for example you may want one with more fiber, or prefer an option with more muscle and performance aspects such as creatine and amino acids.

Most people who want to gain weight choose weight gainers because they can’t or won’t gain the desired weight through food consumption. Some people don’t like eating excessively, and flavor is a critical factor for most consumers when choosing what they eat. The same holds true for weight gainer shakes, which are the most popular form of weight gainer supplements. Taste, flavor, ingredients and brand reputation ranks as the top criteria when considering whether to buy a weight gainer product.

Unfortunately, weight gainers aren’t a panacea for health and fitness, but they do provide a fast, convenient and affordable way to gain weight and build muscle. However, it’s critical to investigate any supplement before buying it. That includes researching the manufacturer, brand reputation, ingredients and other details.

An excellent resource for researching ingredients is the NCCIH Clearinghouse for publications and databases. Consumers can find out information about ingredients, manufacturers, supplement formulas and medical and scientific studies.

What to Look For in a Good Mass Gainer

Arguably the most important aspect to take into account is the overall calorie count. The goal of a mass gainer is to increase muscle mass and this requires getting into a caloric surplus, thus generally speaking the more calories per serving a mass gainer product offers, the more effective it will most likely be.

In addition, because protein is the primary ingredient or building block in most mass gainers, the style and quality of the protein is a factor as well. It is important to see the style of protein, for example whey as compared to casein or if the whey protein is grass fed. The amount of protein per serving size is key as well. Finally, you’ll want to look at the carbohydrate per serving amount as well so you can compare the ratio per serving; if muscle mass is a key for you then generally you’ll want a ratio of more protein, less carbohydrates per serving.

Flavor is of course important and not all mass gainer supplements are particularly tasty or suit your personal preference, you’ll want to search for an option with a flavor you generally like to make the supplement more palatable and easier to use.

Other Things to Consider

Reputation of the Brand

A PBS report on supplements recommends that users ask some complex questions before deciding to take any kind of supplement. The multi-billion dollar supplement industry obviously serves a real need, or it wouldn’t have grown so rapidly. Supplements have become common staples of major brick-and-mortar and online retailers such as Walmart, Target Walgreens and others.

PBS recommends that consumers search each manufacturer’s website and check whether a given supplement has generated any online complaints, healthy warnings, recalls or sanctions. Read any relevant user reviews, and find out if the supplement has been tested by any independent laboratories.

Brand reputation matters because it shows that a company is trusted by other people who are using its products. Testimonials, reviews, complaints, how a company responds to complaints and a brand’s industry reputation can be critical factors in choosing weight gainer supplements intelligently.

Personal Preferences

Pills might be easier for some supplement users, but most people prefer to customize their shakes with their favorite flavors and liquids. Taste and flavor are critical for many people, so it’s highly recommended that consumers try any supplement in the smallest available quantity before buying a larger amount. If the shakes aren’t enjoyable, people will find excuses not to drink them or perform the exercise necessary to build muscle.


Finally, price and budget are a factor as well. When cross-referenced with your other needs, the best option will need to fit into your budget, and while you generally may get what you pay for, there are some very effective mass gainer supplements that won’t break the bank.

The cost of supplements aren’t always easy to determine. It’s important to compare prices based on serving size and the number of grams of each component. The cheapest product might not provide the best value when broken down into servings.

What to Avoid

Supplements aren’t considered to be drugs by the FDA, so choosing dietary supplements that promise to cure, diagnose, treat or mitigate diseases and disorders is risky according to research conducted at Oregon State. So it’s best to avoid products that make exaggerated promises or health guarantees.

Supplements that use protein, carbs and nutrients from unknown sources are another red flag for consumers. It’s important to check the biological value of protein to determine how easily it’s absorbed and used by the body. Too much sugar–in the form of glucose, dextrose, sucrose and fructose–can also generate the risks of raising insulin and serotonin levels.

Too much serotonin can cause headaches, drowsiness and other unwanted side effects. These problems include goose bumps, fatigue, dizziness, agitation, shivering, sweating and dilated pupils.


Trying to gain weight or muscle too quickly can generate undesired side effects. These include unfavorable distribution of weight, added pressure on the cardiovascular system, developing high blood pressure or diabetes and experiencing severe cramps. Depending on the formula of a given weight gainer supplement, it’s possible to develop nutritional deficiencies.

Too much creatine can also cause unwanted side effects that include kidney problems, and impairing heart or liver function. High doses can also draw water away from the rest of the body, so users of creatine-enhanced supplements should drink lots of water. Creatine in the blood is a primary indicator of reduced kidney function, and excessive creatine can cause diarrhea, stomach pains, nausea and muscle cramps.

Allergic reactions are always possible when taking weight gainers. Many formulas contain soy and soy products, herbal supplements, dairy products and other common allergens. Discontinue any product that causes breathing problems, digestive upset, diarrhea, hives or other kinds of health problems.

Monster Milk has one of the lowest calorie counts in the mass gainer category, making it just as much a protein powder as a legitimate mass gainer. It is a great option to increase your protein intake and slightly increase your calories without risking putting on too much additional weight.

  • 184g protein
  • 391g carbohydrates

Wrapping Up

Using weight gainers properly offers many benefits for putting on weight without eating excessively, building muscle and recovering from debilitating medical conditions. Bodybuilders and health enthusiasts can use weight gainers as part of their strategy to accelerate and intensify their efforts to recuperate or build muscle at a higher level of intensity.

People can recover faster from fitness workouts–of all types–with those weight gainers that incorporate ingredients that foster faster recovery rates. These are ideal choices for high-intensity training and extremely competitive athletics.

It’s important to know what kind of weight-gaining supplement best suits anyone’s goals–whether the goal is weight gain, feeding a high metabolic rate, recovering more quickly after working out or building muscle mass. The best strategy is to consult with trainers and the family physician, research supplement brands and ingredients and make an informed decision.

The right information can guide any research effort, and knowing the pros and cons of different types of weight gainers can prevent spending too much money or using supplements with nonessential or risky ingredients.
