Is Mass Gainer Bad For You? Side Effects & How to Avoid Them

Mass gainers can be a handy tool if you struggle to reach your calorie needs. Sometimes, it can be complicated to get enough calories when on a caloric surplus. So, is mass gainer bad for you?

While mass gainers can be a good supplement, there are some side effects of mass gainers you might want to know about before you purchase one.

Here, we’ll answer the question: are mass gainers safe? We’ll discuss the possible side effects and how to use them effectively to get the best results.

Is mass gainer bad for you? Mass gainers can help increase your calories, but they can increase the risk of digestive issues (bloating, gas, and stomach cramps). If not used properly, can increase fat mass and may not provide the necessary macros based on goals and needs.

Is Mass Gainer Bad For You?

Bulking or massing is a phase where you increase your calories (caloric surplus) to gain muscle mass. The proper caloric intake varies according to age, weight, height, activity levels, and goal. Research shows that calorie requirements can go above 3,800 for men and 3,200 for women when bulking.

For someone who is not used to eating a lot of calories, it can become challenging to increase the calorie intake to these levels. As a result, mass gainers can be a good way to increase your calories without feeling too stuffed.

However, since you get a lot of calories in just a small serving size, it means you may get an increased risk of side effects.

Here are some of the possible weight gainer side effects.

1. Possible Digestive Issues

One of the biggest mass gainer side effects is possible digestive issues. Due to the high caloric content of mass gainers, the body might not be used to digesting such a large load of carbs and proteins at once. As a result, it can increase the risk of bloating, diarrhea, stomach cramps, and gas.

If you suffer from digestive issues when taking a mass gainer, this can also affect nutrient intake since the digestive system might be irritated from the supplement.

2. Fat Gain With Excessive Consumption

Using weight gain supplements without working out or using more than you need will increase the risk of fat gain. While you need to be in a caloric surplus during bulking, there is a fine line between too many calories and just the right amount.

Also, in order to gain the mostly muscle mass, you need to increase calories along with an adequate training program. Otherwise, overeating without working out can only increase the risk of obesity and fat gain.

3. Unable To Adjust Macros

Finally, one of the drawbacks of mass gainers is that you cannot adjust the macros you need to take. You need to be careful about the type of mass gainer you choose since some are very high in carbs and might not provide enough protein.

As a result, you might not get the desired benefits (insufficient muscle gain, poor endurance/physical performance).

How Can You Use Mass Gainer Wisely?

So, are weight gainers healthy? They can be if you use them wisely. Here are some tips to help you avoid mass gainer protein powder side effects.

1. Choose Gainers With Better Carb-To-Protein Ratio

Mass gainers offer different macros. Some can be higher in carbs, while others might have a more balanced approach.

If you are not an endurance athlete or someone with high carb needs, you are probably better off with a more balanced carb-to-protein ratio.

The use of mass gainers is also more effective when you understand your protein needs. To gain muscle, you need a good protein intake, ranging from 1.4 to 2.0 grams of protein per kilogram of body weight.

If you struggle to reach your protein intake, search for mass gainers with a 1:1 or 2:1 carb-to-protein ratio. This will ensure you get enough calories, carbs, and protein.

2. Consider The Gut Reaction

To have the best experience using a mass gainer, you need to consider the gut reaction. For example, if you find yourself having bloating and gas after using the supplement, you can break it down into smaller doses throughout the day.

For example, instead of having two full scoops in one take, you can have ¼ scoop in the morning, another in the afternoon, and so on until you complete the desired intake.

You also need to take into account the ingredients used in the mass gainers. If lactose intolerant, you might be better off with a mass gainer that uses plant-based protein instead of casein or whey.

3. Don’t Overdo It With The Carbs

One of the main reasons you might be getting digestive problems is due to the large dose of carbs. Mass gainers that are higher in sugars not only are against the recommended intake of less than 10% of daily calories from sugar, but they can also increase bloating and gas.

Opt for mass gainers that provide more stable carbs (choosing complex over simple) to ensure you get more stable energy levels and fewer digestive problems.

4. Control the Rate of Weight Gain

Finally, while we want to have the results straight away, sometimes slow and steady wins the race. Striving for a stronger weight gain means you need to have a more aggressive caloric surplus, which puts you at risk of digestive issues and fat gain.

If you find that the calories you are eating are too much, you can decrease them to have a less aggressive strategy. If you are unsure how many calories you need, you can always ask a health professional for advice.

Bonus Tip: Use the Gainer Only When You Need It

The best advice we have for you is to only use mass gainers when in need. Once you determine how many calories you need, strive to reach your caloric intake through whole foods.

If you are still missing calories, you can always mix a protein shake and other high-calorie foods, such as oatmeal, nut butter, chia seeds, hemp seeds, and flax seeds. This can make a cheaper, healthier alternative to a weight gain supplement to help you hit your calorie and macro requirements.

You can then use the mass gainers in case of emergency. For example, when on the go or when you are unable to have lunch or dinner, it can be a good meal replacement to have once in a while that will ensure you get all the calories you need to reach your goals.
