Top 5 Vegan Mass Gainers (2021 Updated)

1 - Vegan Naked Mass

Vegan Naked Mass is one of the best plant-based supplements, as it is a mix of pea proteins and brown rice proteins, making for a great companion in providing energy for your workouts. Every serving of Vegan Naked Mass consists of 1230 calories and 50 grams of protein.

Also, each serving of this supplement provides you with 252 grams of complex carbohydrates that can help power your workouts. Moreover, it enables you to gain weight by meeting your daily calorie requirements.

You may have trouble taking in more calories to gain weight, especially if you are a hard gainer. However, with Vegan Naked Mass, which consists of 1230 calories per serving, you can forget about consuming those extra calories.

Since each serving of Vegan Naked Mass consists of 1230 calories and 50 grams of protein, it helps power your every move, especially during those intense workout sessions. Vegan Naked Mass also consists of organic maltodextrin – a substance known to boost and help maintain the energy levels required for working out.

With Vegan Naked Mass, you can also gain muscle mass, and not just calories or weight. Made of Naked Pea and Naked Rice, the supplement provides you with all the nine vital amino acids required for muscle-building and is one of the best plant-based alternatives for those looking to develop their muscles.

5 - Nutiva Organic

Nutiva Organic

As the name suggests, Nutiva Organic is a 100% pure organic and vegan supplement. This vegan protein powder for weight gain is marketed as a complete source of fatty acids, essential amino acids, and protein.

This product is naturally extracted from hemp using a 'cold press extraction' which results in a clean protein powder.

It is full of omega 3 and antioxidants without the addition of harmful chemicals.

It is a smart choice when you choose Nutiva Organic supplement as your partner in gaining weight.

What I like about this vegan protein powder for weight gain is that it has a clean ingredient list (no filler, sweeteners or junk) with only hemp protein as the main ingredient.

  • Calories: 110
  • Protein: 15g
  • Carbs: 8g

  • No fillers, artificial ingredients
  • ​There are other supplements that have higher protein content

In each 30 g serving of this vegan mass gainer, you get 15 g of protein and 8 g of fiber. It's an obvious choice in terms of choosing an organic plant-based supplement for your body.

In summary, this vegan weight gainer would be a great option for people who want to focus on having enough fiber. The body needs plenty of fiber because gaining weight is as important as losing the toxins, too.

How to Gain Weight as a Vegetarian?

There are many hurdles to overcome in your quest to building a great vegan physique:

  • Getting adequate amounts of plant protein and amino acids
  • Supplementing nutrients such as vitamin B12 (check out our list of vitamin b12 supplements)
  • Progressive heavy (and smart) training
  • Convincing friends and family that you're not dying from malnutrition
  • Not eating too much
  • Not eating too little

The last bit about 'not eating too little' is something that I know many of you struggle with. If you want to put on any significant amount of muscle mass, you will have to be in a caloric surplus i.e. eat more calories than you burn.

Any vegan hard-gainer will have a particularly hard time with this endeavor, as whole plant food as a rule of thumb isn't very calorie-dense. For example, to obtain 1000 kcal from broccoli, you'd have to eat 3 kg or 7 lbs of vegetable matter - that’s pretty rough. (1)

1000 kcal from cheese, on the other hand, would be about 250 grams which is a LOT less food volume.

The problem is further compounded by the fact that you are burning calories at the gym that also need to be replenished. If you can relate to these difficulties, you can also look out for a guide that you probably will want to implement in your life.

Why Do You Need a Vegan ​Weight Gainer?

scoop of protein powder

I don't believe there are any strict definitions of what constitutes a "vegan mass gainer". So here's one that I just made up:

"A mass gainer is a high-calorie liquid which helps you put on muscle."

Getting in the calories you need (while not wanting to kill yourself because you are too full) is a hell of a lot easier by drinking calories instead of chewing them.

The products recommended above do exactly this -- providing you with your caloric requirement without making you want to throw up.

People, especially in vegan bodybuilding, typically use mass gainers to put on significant muscle gains.

What are the Ingredients?

protein and carbs

A vegan weight gainer typically takes the form of a beverage made up out of two - potentially three - key components:

1. Protein

Your body needs adequate protein (the basic building blocks of muscle fiber) in order to support the growth and repair of new muscle tissue.

Right around 1.6-2.2 grams protein per kg body weight has been shown in studies to maximize muscle mass growth; adding some extra nutrition to a vegan weight gainer can make it a lot easier hitting these targets each day (2)

2. Carbohydrates

An extra boost of carbohydrates in your vegan weight gain shake provides the energy that allows for a high training intensity in the gym (which means more gains).Moreover, these calories help contribute towards a caloric surplus which promotes an anabolic, or muscle-building, state.

And no don't worry, a surplus coming from carbohydrate won't automatically make you fat. This has been debunked over and over again as keto/paleo/low-carb bullsh*t. In fact, it's been shown that overfeeding with fat leads to greater body fat gain compared to overfeeding with carbs!

3. Healthy Fats

It's not uncommon to find a vegan weight gain powder with some healthy fats thrown in for good measure. A few grams of fat sprinkled in will boost total calories, and is crucial for healthy hormonal function such as testosterone production which increases the rate of muscle growth.

When Should I Take Mass Gainer, Before or After a Workout?

There’s a lot of confusion around this topic. Should you take a mass gainer post workout or as a pre workout supplement?

Although opinion is always going to be divided, most professional gainers agree that post workout is the best option. (3)

This is because your muscles are tired after a workout, so they need energy (in the form of protein isolate and friends) afterwards to help repair themselves and grow bigger.

When you take your mass gainer after working out, you’re providing your muscles with everything they need to grow after their exhausting gym session!

Is It Bad to Take Mass Gainer Before Bed?

There’s a lot of scaremongering (if you can call it that) about taking mass gainers and other calorie-dense products before you go to bed, as some bodybuilders think that this will make you fat.

However, taking mass gainers before bed is common practice in many fitness enthusiasts, who frequently report no adverse effects on their gains.

Nonetheless, if you’re consuming a mass gainer which is high in calories and sugars, it may be best to consume it at a more appropriate time if you can. If nothing else, it could send you on a mad sugar rush just as you’re trying to fall asleep!

Should You Buy One or Make One Yourself?

That’s totally up to you!

If you can find vegan mass gainer products that have everything you need in them, then you’ve just made your life (and your health) a little bit easier. Just place the order and you'll be ready to build some vegan muscles in no time.

If you want something a little more specific, however, then you could consider making your own.

For instance, you might want to mix some vegan creatine in there with a certain type of protein isolate, or perhaps you want a vegan mass gainer infused with rice protein and creatine due to some diet restrictions. You may want to stack rice protein with other plant protein sources to ensure that you're getting all the essential amino acids the body needs.

Below, we give you an idea for a protein shake which works as a great DIY vegan mass gainer if you don’t fancy anything on our list above!

DIY Vegan Protein Shake Recipe

So, you're ready to go from skinny to not-skinny and need a decent weight gainer shake to help you out on your mission. First, let's look at how to make your mass gainer using a blender or any similar device.


Here's a generic recipe that will work really well:

  • 1-2 scoops vegan protein powder
  • Carbohydrate source (e.g. oatmeal, sweet potato, carbohydrate powder)
  • Fat source (nuts, seeds, nut butter)
  • Fruits and berries (e.g. banana, mango, dates, blueberries, strawberries)
  • Beans or lentils (yep, it works)
  • Dark leafy greens (spinach, kale etc)
  • Liquid (e.g. water, nut milk of choice)

Here are two examples of how to tailor this recipe for your needs and goals:

  1. This beauty right here was made from 2 cans of black beans (drained and rinsed), 2 ripe bananas (frozen for milkshake quality), 1-2 heaped tbsp cocoa powder, about 6 pitted dates and about 1 cup of soy milk.
  2. I believe this vegan weight gain powder recipe was something like 1 can white beans (drained and rinsed), 2 bananas, 200 g of frozen mango and pineapple, two tablespoons of flax seeds, two handfuls of kale and then water for desired texture.

This comes out to roughly 600 calories with 20 grams of protein or so.

With the tropical fruits, soy milk, dark leafy greens and flax seeds, you also get a bunch of nutrients and beneficial compounds such as omega-3's, calcium, vitamin K, lignans etc.
