Questions to Consider Before Buying Mass gainer supplements

When buying a mass gainer, there are some aspects that you should pay attention to and that will help you choose the right product for you. In the following list you will find all the criteria that will help you make your decision:

  • Weight
  • Flavor
  • Kilocalories per serving
  • Recommended intake
  • Ingredients
  • Fitness for vegans
  • Dosage form

In the following paragraphs we will explain to you what is decisive for the individual criteria.


Most manufacturers offer their mass gainers in many different quantities. The weight can vary between 1 kilogram and 7 kilograms. So you can choose how much mass gainer you want based on your needs.

If you only want to try out a mass gainer for a shorter period of time, we recommend that you choose a smaller amount, around 1 to 2 kilograms. But if you are sure that you want to use a mass gainer in the long term, it makes perfect sense to buy a large amount.


Most mass gainers offer different flavors. The most common flavors are vanilla and chocolate. You can read through various reviews to find out what you can expect in terms of taste.

If you are still not sure which flavor is right for you, there are a few providers who offer test portions. Usually you get several servings in different flavors.

In addition to flavored mass gainers, there are also tasteless mass gainers. You can give this a taste yourself with a mashed banana or frozen fruit.

Kilocalories per serving

The number of calories per serving is likely to be very important to you as you will need higher caloric intake to gain weight. A higher number of calories per serving also affects how often you have to take the mass gainer.

You have to take a mass gainer with more calories less often than a mass gainer with fewer calories per serving.

So always make sure that the calories per serving are adjusted to your weight goal.

Recommended intake

Powdered mass gainers can be mixed with either water or milk or both. Depending on what you prefer as a shake base, you should research what the manufacturer recommends.

You will also find information on how often a day you should consume the mass gainer. If you travel a lot, a mass gainer is suitable for you and should only be taken once a day. As already mentioned, you should make your decision based on it.


Under the information on the ingredients, particular attention should be paid to whether the mass gainer contains creatine and whether it is aspartame-free. In the following paragraphs, we will explain why these ingredients should be checked.

Creatine shortens the regeneration phase and increases muscle growth.

Creatine is a dietary supplement that is said to have a performance-enhancing effect and promote muscle building. In addition, creatine shortens the regeneration time.

If the effects mentioned are of interest to you, we would recommend getting a mass gainer with creatine.

Aspartame is an artificial sweetener that is said to have negative effects such as an increased risk of cancer or damage to the genetic make-up. A mass gainer shouldn’t endanger your health. Therefore, make sure that the product is aspartame-free.

As you can see, it doesn’t hurt to check the ingredients and take them into account when making your decision.

Fitness for vegans

There are some suppliers who also have vegan mass gainers in their range. If you are completely or partially vegan, you will also find what you are looking for in the wide range of mass crooks.

You can usually tell from the packaging whether a mass gainer is suitable for a vegan diet. There you will find the vegan seal. As with creatine-containing mass crooks, many manufacturers already advertise in the product signature that their mass gainer is a vegan product.

The vegan mass gainers can also be prepared with water or milk substitutes such as almond milk or oat milk.

Dosage form

Most mass gainers come in powder form. Water, milk or milk substitute can be mixed with the powder to make a shake. You can also upgrade your shake with fruit.


Simply put milk or water with the Mass Gainer powder and, for example, a banana in the blender. Your shake is ready.

If you don’t like shakes, there are also mass gainers in bar form. They don’t need any extra preparation and you can eat them on the go with little effort.

Facts about Mass Gainer

In the following, we want to answer the most important questions about mass gainers. We have selected questions for you and will answer them shortly. After you have read the guide, you will know all the essential background information about mass gainers.

Is mass gainer suitable for me?

A mass gainer is suitable for anyone who finds it difficult to gain weight. You gain weight when the calories you eat are higher than the calories you burn, and because of the high number of calories per serving, a mass gainer will help you gain weight.

Especially people who find it difficult to eat a lot can fall back on mass gainers.

The dietary supplement consists of a mixture of carbohydrates and proteins. Usually the product is a powder. Depending on the manufacturer’s recommendation, this can be mixed with water or milk to make a shake.

In addition to mass gainers in powder form, some companies also offer mass gainers in the form of bars. If you are not a fan of shakes, the bars are a good alternative.

What alternatives are there to a mass gainer?

In addition to the mass gainer dietary supplement, there are a few alternatives that can help you gain weight.

  • Whey protein: food supplement that provides a lot of protein to support muscle building
  • High-calorie diet: Achieving a calorie surplus through a diet with high-calorie foods (e.g. shake made from oatmeal, quark, milk and peanut butter)

Every way to gain weight has its advantages. However, mass gainers seem to be superior to the alternatives in some criteria. Mass gainers convince with their high calorific content and easy preparation.

How Often Should I Take a Mass Gainer?

How often you should consume a mass gainer depends on three factors:

  • What are the calories per serving? You don’t need to take a mass gainer with more calories as often. Whereas you should take a mass gainer with a low number of calories per serving more often.
  • What is your weight goal? How much weight do you want to gain? The portions of Mass Gainer that you consume should be adjusted to your daily calorie goal. If you want to gain weight, you should consume about 500 more calories than your daily energy requirement requires.
  • How much time do you have? Do you travel a lot? If you buy a mass gainer in powder form, you also need to allow a certain amount of time for preparation. If you travel a lot, you can prepare shakes at home in advance, but that requires planning. It would make more sense for you to prepare the mass gainer only once a day.

You can use these three points to find out how often it makes sense for you to take a mass gainer.

What else should I watch out for when taking a mass gainer?

A mass gainer is a dietary supplement. It is used to supplement your diet and not replace complete meals.

You should still eat a balanced diet and give your body all the nutrients and vitamins it needs.

When you take your mass gainer is up to you. However, some manufacturers recommend taking the supplement after training in order to achieve the best result.


With the help of a weight gainer you can gain weight effectively and build muscle mass. Compared to other dietary supplements, a mass gainer stands out for its high number of calories – perfect for weight gain. Whether bars or shakes, Mass Gainers impress with their effectiveness and ease of preparation.

If a shorter regeneration time is important to you, we can recommend a mass gainer with creatine. In addition, this ingredient also increases your muscle growth, which is why creatine-containing mass gainers are really worthwhile. Even if you follow a vegan diet, you will find what you are looking for in the wide range and can achieve your weight goal with natural ingredients.
