What is a Mass Gainer Supplement?

A Mass Gainer supplement is a powder that is high in calories where proteins carbohydrates are dominating. So, its purpose is to help you to gain muscle mass, and make your diet easier.

As you possibly know, you need to eat a huge amount of food if you want to gain muscles. It also can be a challenge to eat thousands of calories and get about 1.5 grams of protein per 1kg (per 2.2 lb.) of your body weight. If your weight is about 80kg (175 lb.), you need to eat approximately 120 g of protein and it is about half kilogram (pound) of meat per day, plus a huge amount of correct carbs. Most of the people have issues with that, and then mass gainers are coming for help! 

Of course, you need to remember that weight gainers are meant to be used only if you are working out. In another way, you will just be getting fat from these small calories bombs. 

Benefits of Mass Gainer

Helps with muscle growth – If you work out regularly, then mass gainer is a nice supplement for your muscle growth. Normally it includes protein which contains amino acids that are the main nutrient for the building muscles. Also, mass gainers provide a huge amount of carbohydrates, which can help with muscle growth (if you work out) and gives you extra energy (1).

Recovery– the high carbohydrate amount helps you to restore glycogen levels in your muscle, while the protein helps kicks your recovery and help muscle growth. Also, L-glutamine, another common nutrient weight gainer contains, which is known as a good post-workout nutrient (2). 

Contains fibre – Since you will be eating a lot of food (what is necessary if you want to gain muscles), fiber will be normalizing your bowel movements. Also, it can limit the absorption of sugars and control your blood sugar levels. Fiber is a really necessary nutrient when you are consuming a huge amount of protein food (3). 

Weight Management – Some people use mass gainers to maintain their current weight. For example, ectomorphs (skinny people who cannot gain weight), or also endurance athletes. Endurance athletes usually have huge calories need, as they are burning a huge amount of calories during their workouts.

How And When to Take a Mass Gainer

Mass gainers supplements usually have a nice taste, so you can mix it with water or with milk (if you want to have more calories) what makes it even tastier. Most people prefer to take it with milk because it just tastes better.

Now about when to take it. Actually, there is an opinion that it is better to take it immediately after your workout, but the thing is that it doesn’t make a big difference. Of course, the carbohydrates and protein are opened about 30 minutes after your workout, but the thing is that nutrients absorption doesn’t happen so fast. Also, it is more about your daily calories (protein, carbohydrates, and fats) intake

Also, remember to follow directions on the packaging and don’t exceed recommended dose.

Who Can Benefit from a Mass Gainer?

All type of athletes– a big part of the sports requires to have some muscles. Many athletes can benefit from the mass gainers which contains necessary nutrients for muscle growth. Also, mass gainers contain a big amount of calories that can give you a big amount of energy for the full day (4). 

Bodybuilders and also other weight lifters– to build muscles you need a huge amount of protein and carbs and also calories surplus. Especially when athletes are on the period of bulking. Weight gainers can help you a lot with it, and it can be a kind of dessert for you. It is really a nice helper especially when you need to take this huge amount of calories. 

People with fast metabolism or ectomorphs– These people usually need to have bigger calorie intake, sometimes they struggle even with weight maintenance. In that situation, mass gainer can be a perfect supplement. Also, it is more difficult to gain weight for them, so as mentioned above it is a perfect supplement for these types of people. 

Men and women– everyone can benefit from mass gainers men and women. If you need extra calories intake it is a perfect supplement. It makes life easier for you, and you don’t need to eat tons of food. Of course, usually, men need more calories than women, but some women need extra calories too (5). 

Do the Mass Gainer Has Any Side Effects?

Allergic reactions– as you already know, mass gainers have a quite big amount of nutrients inside, which in most cases are beneficial, but some people can be allergic to various ingredients. Usually, these allergic reactions show as itchiness or stomach upsets. Anyway, if you are allergic to something, check what is written on the back of packing and better consult with your doctor. 

Overweight or fat gain– this can happen only if you are not controlling your food intake and do not count nutrition. Usually, it happens when you have a big calorie surplus, but it is easily avoidable if you just count what you are eating. Also, for some individuals who are endomorphs (people who are gaining weight faster), it can be a little more risky, as mass gainers usually are very high in calories. 

Some pressure for liver– as you know, mass gainer contains a big amount of protein, which is making your liver work harder. But, it happens really rare and only in a situation when athletes are using too much protein (from food too). Just take an adequate amount of protein, do not take more than 1.5 grams of protein per 1kg (per 2.2 lb.), there is no use of it, muscle growth will not be faster if you will eat more (6).

As we told ingredients are very important, but also you will need to find out how many servings you can get per container and how much it will cost for you. Just be sure that you are not spending more than you should!

Usually, unknown companies with no history, are not staying on the market for too long. Quality can be worse, they are not checked by clients, and they also just can’t compete with the best companies on the market. That’s why we always provide you information about all companies, and we try to choose the products with the best nutrition composition with the most known brands on the market which you can trust.
