Mass Gainers Buying Guide

Now that you know what is in the market, this is what you should do: If you’re struggling with gaining weight, you can check in with your doctor to determine the cause. If it’s because you have a high metabolism, then a mass gain re will come in handy in your daily diet. If you’re an athlete and your progress has plateaued, measure your daily calorie intake and purchase the supplement that can give you the additional nutrients that you may be lacking in your diet.

Editor’s advice: Do not depend on mass gainers alone. You should take your supplement alongside a balanced diet made up of healthy foods that also support weight gain if you want to realize optimum results. Either way, make sure your purchase is from a verified vendor and the product is legit. If in doubt, choose one of the best we have thoroughly researched and listed above for you to review.

Do Mass Gainers Work?

Yes! Consuming them will lead to weight gain — assuming that the extra calories you consume exceed the Total Daily Energy Expenditure (TDEE). However, in certain instances, you may not achieve the weight that you want.

Remember, as you break past the marketing hype, there is no mystical muscle-building recipe out there; instead, they are just good strategies of dumping fat in your body quickly enough. As a result, for many people who aren’t careful, it’s really likely to wind up with a majority of the extra weight you gain coming from fat rather than muscle mass.

Benefits and Side Effects?

Like any other manufactured consumable out there, mass gainers also have associated pros and cons. Let’s begin with the benefits:

  • They’re super high in calories, therefore achieve their goal of adding weight
  • There are both post-workout and daily value varieties out there, so you have many options to choose from
  • They can help you achieve your creatine needs easily
  • They help in post-workout recovery
  • Some enhance strength gain alongside muscle mass

Although most mass gainers have almost no negative side, some users have reported mass gainers’ side effects such as:

  • Dehydration: Taking these supplements while not taking enough water may lead to dehydration. Just like working out, hydrating yourself while taking these supplements is one of the key elements to bulk up
  • Liver problems: Besides aiding in metabolizing fats and carbohydrates, the liver is also responsible for metabolizing proteins in your diet, so if you add more than your usual protein intake, the liver also does more work. To avoid overworking your liver, follow the specification provided by the manufacturer and avoid alcoholic drinks.
  • Diarrhea: When there is a complication in the digestive tract, one is likely to get diarrhea. Lactose intolerant individuals are also likely to suffer the same. To prevent this side effect, always have your supplement shake an hour or two before your workout and drink plenty of water, as well as incorporating additional nutrient-rich foods in your diet.
  • Breathing complications: When taking mass gainers, some common breathing complications one is likely to experience are sneezing, coughing, wheezing, and on rare occasions, asthma. Your body is designed with a respiratory system that can provide adequate breathing capacity to a certain body weight at a time. Using mass gainer supplements may bulk you up and get your body to a point where it can’t support your breathing capacity, leading to complications.
  • Kidney problems: Mass gainers contain proteins that are made up of amino acids that have an excess amount of Nitrogen. If you get an extra amount of proteins in your body, your kidney has to get rid of the excess Nitrogen and other by-products of protein metabolism.

Are Mass Gainers Safe?

Although there is a bit of skepticism about the ability of mass gainers, the supplement industry maintains that mass gainers are one of the safest products. However, it’s quite hard to determine which will work best for you as people react differently to different products. Unlike pre-workouts and fat burners, they don’t carry high health risks.

Mass gainers are majorly made of three macronutrients that are proteins, carbohydrates, and fats. In a standard package of between 200-300g, a mass gainer contains about and not more than 20% protein and more than 70% carbohydrates. This can vary from product to product, but the order of predominance does not change.

Some may contain vitamins, minerals, and their ingredients in small amounts.

NOTE: As much as mass gainers are safe to use, they are not really necessary. In fact, they can easily be made at home by mixing protein, oats, and peanut butter. Before deciding to use mass gainers, you should begin your weight gain journey by consuming more calories than you burn. That is being on a calorie surplus. Gently increasing your calorie intake by a further 500 calories per day can result in an increase in body weight per week.

Tips For Choosing a Good Mass Gainer

  • First, you need to ensure the mass gainer has all the nutrients needed. That is a complete supply of healthy fat, carbs, and proteins according to the calorie requirements.
  • Know the number of calories per serving. This depends on individual needs, but the range is 1200 calories or higher per serving.
  • Consider micronutrients. By micronutrients, we mean vitamins and minerals. Some people prefer a lot of these nutrients in their mass gainers, while others may not.
  • Get your favorite flavor of weight gainer. Remember, most mass gainers are taken two to three times a day. You want something that tastes good, not like medicine.
  • If you are getting the supplement for the first time, buy a smaller bottle to try first before you settle on the supplement.
  • If you want to buy a post-workout mass gainer, choose one with fast-release Glutamine, BCAA’s and proteins, and little fat. The supplement must have a good supply of carbohydrates, too, for energy.
  • Check the customer reviews and ratings on sites such as amazon. These represent some of the most discerning and honest opinions about any product. However, be sure to review multiple reviews before you settle on an opinion. Remember, some people just write reviews for the sake of writing, and some give false accounts.
  • Confirm the manufacturer: A good mass gainer is one that is manufactured in a GMP-certified facility anywhere in the USA.

Mass Gainer Etiquette

  • Be sure to mix the powder well with milk, water, or your preferred beverage. We do not recommend alcoholic drinks, though.
  • While mixing, use a shaker or a blender if lumps are visible in the drink. It will taste better when it’s all fine and smooth.
  • Take your supplement 30 minutes after working out because that is when muscle-building and recovery are at their peak.
  • Prioritize sleep while taking mass gainers to ensure good rest
  • Every 3-4 hours, make sure to eat something to keep your body fueled to avoid burning fat.
  • If you take the mass gainers, don’t sit idle and wait for a miracle. You got to move the scale to realize results.
