1. NAKED MASS by Naked Nutrition

The Naked Mass weight gainer is our first on the list for the best weight gainers and is an unflavored powdered supplement. With just three simple ingredients, your body will be filled to the brim with protein, complex carbohydrates, calories, and BCAAs for maximum weight gain.

What we particularly like about this product is the use of nutritional protein supplements—not just any old, poor-quality protein. For example, grass-fed whey protein and casein are some of the best to increase protein synthesis to optimum levels. This means your muscles will rejuvenate a lot more rapidly.

Another great element of this Naked Nutrition weight gainer is the ethos of reducing the steps to get the product from the farm to you. This means it doesn’t just fuel you, but it also prevents unnecessary harm to the environment via air and land miles.

The Benefits of Weight Gainers for hardgainers

The best weight gainers provide you with ingredients to fuel your workout, to:

  • Help boost your energy in the gym.
  • Implement the repair and growth of your muscles to gain muscle weight.
  • Improve your overall body’s health.

Before we delve into more details, we’d like to make it clear that if you are skinny or a hardgainer and want to build muscle, you can’t simply rely on a weight gainer. Instead, you have to couple this with a vigorous workout routine, mirroring that of a bodybuilder on top of consuming calorie-dense foods.

One reason for this is that if you consume high levels of protein without needing it to repair your muscles, this can actually convert to sugar, and then fat.

What to Look for in the Best Weight Gainers

Now, before we tell you some of the best weight gainers on the market, it’s important you know what to look out for when you’re on the hunt.

High Levels of Protein

When you exercise intensely, your muscles become damaged and the body needs to repair these muscles so they can grow. Protein is responsible for this growth and repair so, especially after the toughest workouts, this is an important factor in the best weight gainers.


BCAAs, or branched chain amino acids, are quite commonly found in the best weight gainers. Made up of three amino acid chains—leucine, isoleucine, and valine—they help the process of protein synthesis.

What’s this, you ask?

Well, when you consume amino acid chains, these are broken down and then pieced back together into the necessary proteins for repairing your damaged muscles. So that’s why BCAAs are so important in the best weight gainers.

Low Levels of Simple Carbohydrates

As I’m sure you’re aware, simple carbohydrates, like sugar, are commonly known to cause fatty weight gain. That said, if you consume more complex carbohydrates, like legumes and vegetables, this is a much better way to provide energy and reduce heart problems. Therefore, the best weight gainers shouldn’t contain a lot of sugar.

Calorie Dense

As you’re no doubt aware, in order to gain weight your body requires a calorie surplus. So it’s only natural that we’d like to see a high level of calories in your diet for muscle gain.


We’ve certainly done the rounds here when it comes to the best weight gainers for hardgainers. Every one of the above has some really positive elements. That said, we have to pick one as our favorite, and our choice is the NAKED MASS by Naked Nutrition.

For starters, this one includes high levels of protein, carbs, and calories, which can really help you to gain weight by promoting the repair and growth of your muscles. What’s more, this is furthered by the inclusion of BCAAs which, as we’ve already seen, are also known for these properties.

What we really like, though, is the use of natural ingredients, and no GMOs or artificial products. This includes protein like whey and casein, which are not only natural but also the best at helping along protein synthesis.

Our only issue with the Naked Nutrition weight gainer is the use of four scoops per serving. That said, if you’re looking for an all natural product that does the trick, this one’s your guy.
