What Is A Muscle Gainer?

A muscle gainer is a type of supplement that is designed to help you add muscle mass. It does this by providing the body with muscle-building nutrition, specifically protein, usually in the form of amino acids, as well as sometimes carbohydrates and good fats. Muscle gainers are specially formulated to benefit your muscles and help you to optimise your workouts for maximum gains and performance. Here we show you some great ways on how to gain lean muscle.

How Do They Work And What Do They Do?

The majority of muscle gainers are made up of amino acids. These are known as the ‘building blocks’ of protein and are used to help repair and grow muscles as well as aid recovery. When you intake the correct amount of amino acids, your body enters an anabolic, or muscle-building state. As a result, the amino acids work to encourage protein synthesis which stimulates the production of new muscle mass. They also help to prevent muscle tissues from being broken down and can even assist with muscle recovery. As a result, muscle gainer supplements work to do three main things:

  • Build muscle mass
  • Protect the muscles to prevent damage
  • Aid muscle recovery after exercise

What Is The Difference Between Muscle Gainers And Mass Gainers?

As the two names suggest, these two types of supplements work in different ways to reach different goals. Muscle gainers aim to help you increase muscle mass and take care of your muscles before and after a workout. Mass gainers, on the other hand, are super high in calories and are designed to help you put on weight overall. These are also known as weight gainers and can result in the excess weight being put on as fat instead of muscle mass.

Why Use A Muscle Gainer?

If you’re looking to give your exercise a boost and maximise the results of your workouts, then a muscle gainer is the perfect choice. Muscle gainers help to build mass, but can only work properly when used alongside regular workouts and muscle-building exercises. Therefore, if you’re trying to strengthen and build muscles, then a supplement like this can give you a helping hand.

Plus, they can also help you to prevent fatigue and damage to your muscle caused by strenuous exercise and help reduce recovery time, soreness and pain after a workout. You can’t get these benefits just by exercising alone, so if you’re serious about your muscles, then you need to give one a go.

Which Is Better - Tablets Or Powders?

When it comes to muscle gainer supplements, they can come in all different shapes and sizes, with the two most common being tablets and powders. The main differences people look for when choosing the right one for them are the ingredients, quantities and strengths, but the type can be a big factor. So, how to choose? In some cases, it can be argued that powders can be more easily absorbed by the body, but it’s mostly down to personal preference as to which one you go for.

If you prefer something that is quick and easy, then a tablet is probably your best choice. These are also great if you like to take your supplements at a set time each day for ease of use. If, on the other hand, you like to be a bit more creative with your supplements, then a powder is for you. These can be added to your favourite smoothies and shakes so that you can get multiple forms of nutrition in one go. You can also get powders in different flavours if you prefer something a bit more tasty than a plain tablet. Both, however, can work just as well as each other, so the choice is up to you!

Amino Acids For Muscle Building

So, now you know how muscle gainers work and how amino acids can help to build muscle mass, which is the best one to choose? When it comes to picking the right muscle gainer supplement for you, it's important that you know about the different amino acids you can find in these types of supplements. Here are some of the best and most popular amino acids found within muscle gainer supplements:

  • BCAAs (Branched Chain Amino Acids)
  • L-Arginine
  • L-Glutamine
  • Beta-Alanine

Muscle-Building Foods

Alongside taking muscle gainer supplements, there are also plenty of foods you can add to your diet to help give your muscle-building a boost. These help your muscles in different ways and not all are for meat-eaters; you can even find vegetarian and vegan-friendly muscle-building foods!
