The Top 5 Mass Gainers Reviewed

mass gainer review

Exercising helps many people lose weight, and it is often associated with slimming down and dropping dress sizes. However, some people prefer to exercise to add muscle mass and actually grow bigger for a better physique or improved performance. While losing weight calls for a calorie deficit, gaining weight in the gym means you’re going to have to consume a larger number of calories on a daily basis.

Eating a lot of food is not desirable for everyone, however, and some people who want to gain weight cannot seem to keep up with their necessary calorie intake. This can be frustrating as you’ll see little progress in the gym and may feel nauseous and bloated from all the eating, which is where mass gainers come in.

In a hurry?

We know you’re probably itching to get to the gym with your new mass gainer in tow, so we won’t hold you up any longer.

Out of all of the options we looked at on the market, the Optimum Nutrition Serious Mass Weight Gainer Protein Powder was the best option in our eyes.

Below are just a few of the reasons why we think so:

  • Per serving you’ll get a large number of calories, protein, carbohydrates, and 25 vitamins and minerals.
  • It comes in six different flavors to choose from.
  • You can mix it with almost any ingredient to increase the calorie or macro amounts.

Mass gainer supplements are powders that you can turn into drinks or place into your food to increase your calorie intake. Liquid calories are often much easier to consume than those found in food, which is why mass gainers have become so popular among bodybuilders. Mass gainers are full of carbs, protein and some include amino acids as well, so you can rake up your macros as well.

Below we have found the best mass gainers on the market, so you can spend less time looking and more time gaining. We’ve also included a buyers guide full of the most important factors to remember when looking for your new mass gainer.

Mass Gainer Buyers Guide

Now we’ve looked at the five best mass gainers available on the market, below we’ll talk about some factors to take into account before settling on one mass gainer. Remembering these factors while comparing different options will ensure you choose the best mass gainer for you and your goals.

Benefits

Chances are that you won’t be taking mass gainer supplements for the fun of it, but rather to up your calorie intake so that you can fuel your muscle gain effectively. This means that the benefits that come from a mass gainer are rather important in the decision of whether or not to go for each product.

The majority of the benefits are going to come from the ingredients, so let’s look at the main ingredients you’re going to want to focus on.

Calories

When looking to bulk up, you should make a regime that tells you what your calorie intake should be per day. Once you have this information, you’ll be able to find a mass gainer that helps you achieve your calorie goal the best. Some mass gainers offer as little as 500 calories per serving, while some reach up to 1500 calories per serving.

The mass gainer you choose should have the right amount of calories that you need to achieve your daily intake goal. If you find it extremely difficult to reach this number, a higher calorie option is the right way to go, whereas if you don’t find it difficult and just need a final push, a less calorific option may be better suited to you.

Macros

You want your mass gainer to be full of protein and carbs, with very little fat content. Again, you may have a target in your regime that tells you the macro ratio you need to achieve, so this may sway your decision on which supplement to choose. The majority of weight gainers will hold around 40 grams of protein and 70 grams of carbs, however, the latter can reach up to 250 grams. Everyone is different so it’s important to make sure that you’re choosing the right macro ratio for you.

Other Ingredients

The ingredients list is an important thing to check before choosing your mass gainer. Some brands tend to hike up the carb and calorie amount by using unhealthy ingredients such as sugar, which is counterproductive and may increase your fat intake to an unhealthy level.

Other ingredients to look at are the vitamins and minerals, and the amount of each per serving. You don’t want to go over the recommended daily amount as this could potentially be dangerous, so be sure to check that everything is proportionate and healthy before consuming.

Price

Mass gainers are considered rather expensive for what they are, however, many trainers believe that the price is worth it when you weigh the price against the benefits and effects. That being said, you may be slightly frustrated with your chosen mass gainer if you open it and only find that you have a handful of servings after spending a hefty price.

It is always worth spending a little time working out how much it is going to cost per serving, rather than for the supplement overall. This way, you’ll be able to see how much use you’ll get out of your purchase, as there’s no use spending more money for only three days worth of use.

Be cautious of mass gainers that have low prices, however, as this may be an indicator that the ingredients used to make it are not as high-quality as they should be. This may affect your muscle growth and recovery, so you should try and find a mid-priced mass gainer to ensure you’re getting a good performance without having to spend too much money for a few servings.

Different Flavors

Poor tasting mass gainers can force you to stop drinking them and wasting your money, which is why finding a flavor that you’re going to enjoy is very important. Some flavors require a lot of sugar to create, so bear in mind that some sweet flavors may not be the healthiest option. Moreover, some flavors sound nice but don’t taste anything like what they’re meant to, so check customer reviews to see if people actually find it nice or not.

Brand

You can often tell quite a lot by the brand of a product – if they are well known and reputable, your product is more likely to be trustworthy and of a higher quality than if the brand is unknown. Of course, this is not always the case, however, when dealing with consumable products it is often better to be safe than sorry.

Also, make sure to check the customer reviews to ensure the product is legitimate and offers a good performance. There are unfortunately a few fake products on the market, and the reviews are the place to look to ensure that you’re not accidentally purchasing a counterfeit product.

Frequently Asked Questions

What are the side effects of mass gainer?

Some users of mass gainers have reported side effects that can potentially harm the body, so it is advised that you consult your doctor before taking any supplements, like weight gainers. A list of side effect risks that have been associated with mass gainers follows:

  • Muscle aches and pains: People who overtrain after using muscle gainers can often pull their muscles or suffer from painful cramps. This is because not enough fluid can get to the muscles.
  • Nausea: Although uncommon, weight gainers have been seen to cause nausea and diarrhea due to the powder not being used correctly. If you use too much powder, it may not dissolve completely and therefore may cause you to feel ill if it cannot be digested properly.
  • Liver problems: These have been reported after weight trainers have used too much mass gainer for the body to keep up with. Mass gainers can be fatal when used with alcohol, so make sure to read the instructions properly before using your supplement.
  • Breathing problems: Another side effect of consuming too much mass gainer is breathing problems such as coughing, wheezing, and sometimes can even develop into asthma. People with existing breathing problems should not consume mass gainers, to begin with as it may make them worse.
  • Weight gain: If you consume more calories than you can use for fuel while training, the excess can turn into fat and cause unhealthy weight gain. To prevent this counterproductive side effect, make sure your calorie intake matches how many your workout routine calls for.

Can mass gainer replace meals?

You can use most mass gainers to replace a meal every now and again, however, it will be more effective to use your weight gainer alongside your meals to ensure you achieve your daily calorie goal.
