What is a Weight Gainer?
Simply put, they’re supplements used to gain weight. If you’re using a weight or “mass” gainer, you’re probably in the business of gaining muscle and blowing your physique up to a new level.
This type of supplement is necessary for some people; as long as you’ve tried your damndest via diet and training to gain weight the old fashioned way, weight gainer shakes might be the ticket to actually adding pounds to your body and weight to the scale.
Normally, weight gainer supplements involve a ridiculous amount of protein, which is the building block of muscle in your body.
As well, it packs in a ton of carbohydrates, which is key for gaining mass period. The compounds in carbohydrates are burned as fuel for your body, and any remaining compounds are usually stored as body fat.
If you’re taking a mass gainer, it’s because your metabolism or something else is taking those carbs and passing them through too quickly for your body to absorb them.
So, this supplement is designed to pack your system full of macronutrients so that it has to deal with all of it.
Trust us: Weight gainer supplements are a lot of calories. These shakes are for those who are truly desperate to gain some size on their bodies.
If you haven’t really given weight gaining a try with adding calories to your nutrition or training hard for hypertrophy (muscle growth), then it isn’t time to consider a weight gainer supplement.
However, if you’ve upped your calories to high heaven and train like a beast without seeing many results, maybe a weight gainer is right for you.
Weight Gainer for Men
The men are the lucky ones. Most weight gainer supplements are geared towards males, boosting calories like crazy with almost a reckless abandon.
Your appetites are usually higher and you can train at higher weights (though relative strength might be similar).
If you’re a man looking to gain weight, these types of supplements are terrific choices.
Weight Gainer for Women
Sadly, for women, it’s a little more complicated.
Actually, then again, maybe not.
For women, usually it’s easy enough to gain weight by adding food or whey protein. For those with ramped-up metabolisms, there are some weight gainer supplements geared towards women.
However, the majority of supplements are actually nonexclusive; they cater to both the males and the females.
Our bodies may be different, but they aren’t that different. Adding mass to your body is a basic equation of calories in vs. calories out.
Weight gainer supplements include a sh*t-ton of calories. For a lady, you might want to lower the dose, but otherwise weight gainers work the same for both genders.
Weight Gainer Benefits
Aside from the obvious? Weight gainers actually have a plethora of advantages.
Here are the biggest benefits of taking a mass gainer supplement:
- It can help you gain muscle mass faster: No duh. While some studies have found that taking a weight gainer supplement with both protein and carbs doesn’t necessarily work better than a traditional protein powder, that doesn’t mean it will work any worse. Other studies have found that the mixture of protein and carbohydrate was enough to stimulate protein synthesis, a.k.a. how you build muscle. (Quick note: Getting a weight gainer with creatine is ideal, as it’s been found to be more effective.)
- It can help boost training recovery: Muscle glycogen is the main fuel for intense workout sessions; rebooting via glycogen synthesis can take a while after a workout. By taking mass gainers, you increase the amount of carbs you ingest, which can speed up glycogen synthesis and get you back to baseline (mass gainers with protein and carbs works better than a simple carbohydrate recovery drink). Improving glycogen synthesis post-workout is insanely helpful for recovery purposes.
- It can improve exercise performance: Turns out, there are a handful of studies concerning the impact mass gainers have on aerobic and anaerobic For sure, weight gainers have an effect on sports-related activity, which could be beneficial for your specific scenario.
- It can increase protein balance: A vital thing for muscle growth and muscle recovery, protein balance is when you’re consuming more protein than you’re using, or breaking down. Exercise of any kind uses protein, so you have to replenish your protein stores. Enter weight gainers. In terms of whole body net protein balance, the consumption of both carbs and protein was more effective than carb-only supplements. (Again, no duh–you get additional protein with a mass gainer.)
The researchers keep coming back to the protein-carbohydrate combination as the key for enhanced benefits. Protein is great; carbs are fantastic; together, they’re unstoppable. (And so are you.)
Weight Gainer Dosage
This is where the money–and the muscle–gets made. Overdo it and you gain a bunch of unwanted body fat. Underdo it and you get stuck in the same situation you found yourself in before. Dosing your weight gainer supplement is critical for your physical development, so it’s time to be really flawless with supplementation.
This number depends solely on what your weight gain goals are. Certain alternatives have there specific guidelines; for instance, creatine has been found to be extremely effective in doses of about 0.3g per kilogram of bodyweight.
However, this is ideal during a loading phase, and research has shown that taking a lower dose (~0.03g per kilogram of bodyweight) is just as potent over the long term.
As for protein, there is no upper limit. So it really is up to you.
A solid starting point would be to follow the recommended serving size on your weight gainer packaging. After a few weeks on the supplement, you’ll probably be able to determine whether your rate of weight gain is too fast or too slow…or nonexistent.
This can range from 150-250g of the supplement. This will give you 600-900 extra calories, which should do something to your overall mass, so long as you continue to eat and exercise like you normally do.

When Should You Take a Weight Gainer?
Any time of day should be fine for consuming your weight gainer. However, one would do well to get into a routine of daily consumption at around the same time of day.
If you want to maximize your muscle gain, take your mass gainer during times in the day when protein synthesis is high; this would mean after a workout or as soon as you wake up in the morning.
Convenience is the key, but if you’re going for ideal, then go for the above times.
How Long Do Mass Gainers Take to Work?
Again, this is dependent on body type, metabolism, training, nutrition, and a whole host of other factors. That being said, you should be able to see results fairly quickly.
If you don’t see changes in the first two or three weeks, consider upping your dose or switching up your mass gainer supplement.
Weight Gainer Side Effects
Unfortunately, there are some adverse effects to be on the lookout for. One thing you don’t have to be concerned about, though, is overdosing on mass gainers.
It’s virtually impossible to take too much to the point of fatality. However, if you go too hard for too long, you’ll gain unwanted body fat, which can create adverse effects of its own.
Best to avoid going nuts with the dose.
Here are some of the more common side effects from taking a *normal* amount of weight gainer supplement:
- Gastrointestinal distress: This is mainly for weight gainers that include creatine in their formula. Some people are sensitive to the components in creatine, mostly in the gut or stomach. This is usually inconvenient or annoying at worst and can be avoided by regulating your dosage.
- Cramping: This is especially common when you increase your consumption of protein and carbohydrates without increasing your water intake to some degree. Whey protein and carbs alone don’t normally have side effects. But when you include creatine in the mass gainer, your gastrointestinal system can get a little dysfunctional. By simply maintaining a regular daily dose and drinking plenty of water–such as making your shake with plain H2O–you should be able to steer clear of these first two side effects.
- Body Fat Gain: We’ve already touched on this one briefly. If your dose happens to be too much for your body’s ability to turn it into lean mass, the rest will be stored as body fat. Unless you’re burning more calories than you’re consuming (i.e., a caloric deficit), the remainder will convert to adipose tissue, to be stored for later use. This is where trial and error come into play; if you notice in the mirror or on the scale or with a body fat measuring device that your body fat is increasing, tone down the mass gainer dosage.
That’s it! There aren’t many side effects because these supplements are essentially whey protein with additional carbohydrates, some sugar and some fiber.
It’s a literal supplement for food, in liquid form. Therefore, there aren’t a ton of bad things that can occur from taking them.
In fact, all three side effects listed above are also side effects from eating too much period. If you overeat, your gut will be pissed at you and you’re at-risk for gaining body fat.
The same rules apply here with weight gainers.
Mass Gainer FAQ
Are weight gainers bad for you?
Not necessarily. Weight gainers get a bad rap from some fitness circles due to the quality of ingredients.
It’s true that the carb sources aren’t the best, but the point of a mass gainer is to add calories in a quick and easy way. You can’t possibly add anymore calories to your normal nutrition scheme, so a weight gainer shake is the next option available.
They aren’t bad for you from a side effect view of things, but not all of them have great ingredients, which you may care about.
What’s the best tasting weight gainer?
This is 100 percent personal preference. Some people like chocolate, others enjoy vanilla. There are other flavors as well, such as cookies and cream and even banana.
Hell, there’s an unflavored option for some weight gainers too. This is not a question we can answer; you’ll have to figure this one out for yourself.
Who should drink weight gainers?
People who are looking to increase muscle mass and improving exercise muscle recovery. Also, those who want to improve protein balancing.
When should I drink my mass gainer?
We cover this in detail above, but the gist is this: Whenever it’s most convenient for you.
If any time is convenient for you, then go for right after your workout or immediately upon waking in the morning. Both instances are ideal for protein synthesis, meaning you’re optimizing muscle gain.
Can I use a mass gainer before my workout?
Of course! Timing isn’t as important as other factors, like convenience and making it a daily habit. So long as you drink your shake every day, you’ll be good to go.
Can I take a weight gainer on days I don’t train?
Yep. This will keep your calorie intake high. If you’re looking to increase mass, then the more the merrier.
However, if you want to limit the amount of fat gain you get during this experience, you may want to have some days with higher calories and some closer to maintenance.
In this case, we would suggest taking weight gainers on training days only. As for it being an issue, you can take weight gainers whenever.
Should I take my weight gainer with food?
You don’t have to. In fact, for some people that’s too many calories at once.
Your body could feel very full after consuming your weight gainer shake, so consider your own eating habits before deciding to include it with one of your meals or just making it a snack aside from your normal nutrition protocol.
Do weight gainers work?
Once you get the dosage correct, you should gain muscle mass. So yes, it works.
If studies on whey protein powders and carbohydrate recovery supplements showcase a massive array of support, then the both of them as one supplement should net the same benefits.
Which mass gainer is best for beginners?
Beginners, advanced trainers, anyone in between…it doesn’t really matter.
While everybody’s bodies are unique and different when it comes to metabolizing and using whatever’s consumed, it’s generally safe to say extra protein and carbs will boost weight gain, no matter the brand.
So the answer is any weight gainer. (However, we will note that, as a beginner, you might experience better results initially than those who are more advanced and might be closer to their natural mass threshold.)
Will mass gainers make you fat?
If you utilize mass gainers irresponsibly or are taking too much, then yes, you will gain adipose tissue, or fat.
This is easily avoidable: Lower the dose. Continue to lower the dose until fat gain is at a minimum and muscle gain is noticeable.
Do weight gainers help build muscle?
That’s the idea. Mass gainers improve protein synthesis and protein balance to increase muscle building processes in the body. On top of that, the supplement includes a fair amount of carbs to enhance glycogen synthesis and exercise recovery and performance, which means you can train more often at full energy. More training + heightened protein availability = massive muscle gains.
