What Do Protein Powder For Weight Gain / Mass Gainers Do?

Mass and weight gainers are sports nutrition products that are designed to help athletes and bodybuilders bulk up and gain weight. They usually come in powder form, and can be mixed with water or milk to create a shake. 

Protein powders for weight gain typically contain high levels of protein, carbs and calories, making them ideal for those who struggle to consume enough calories and nutrients through their diet alone.

While these powders can be beneficial for those trying to bulk up, it’s important to choose one that contains quality ingredients and is appropriate for your individual goals. Not all protein powders are created equal, and some may even do more harm than good.


How To Choose A Good Protein Powder For Weight Gain For Your Needs

Here’s a look at some things to consider when selecting a protein powder for weight gain.


There is no one-size-fits-all answer to this question, and truth to be told there often isn’t a universal “best time” to drink your gainers. What’s most important is that you’re getting adequate calories, protein and nutrients in general. However, general advice often recommends drinking mass gainer early in the morning and immediately after workouts.

There is no definitive answer to this question, as mass gainers can have different effects on body weight and muscle growth. Some mass gainer supplements may help to increase muscle mass, while others may cause weight gain. The best way to find which mass gainer supplement is best for you is to speak with a nutritionist or doctor who can help you create a personalized nutrition plan.

Nutritionists and weight-loss experts generally agree that mass gainer supplements can be useful for people who are trying to gain weight or muscle mass. However, there is no definitive answer as to whether mass gainer supplements should be taken every day. Some people may find that taking mass gainer supplements regularly helps them gain weight more quickly, while others may not see any significant benefits. The best way to determine whether taking mass gainer supplements daily is best for you depends on your individual goals, schedule, and workout routine.

To gain weight, you must consume more calories than you burn. Mass gainers help you do this by simply adding calories to your diet, and they’re often the easiest way to do so, but they certainly aren’t the only option.


While these are our top picks, it’s always best to consult a doctor or nutritionist before taking any supplements, as they may recommend alternatives.

Whether your fitness goal is to add muscle with minimal fat or to bulk up all around, there are a lot of choices out there and we hope this guide helps you compare the multitude of products!
