Who Are Mass Gainers For?

Expert
Expert

Mass gainers can be beneficial for people with a fast metabolism or who have trouble eating enough calories and protein to promote muscle gain. 

Who Are Mass Gainers For?
Some people face a somewhat unexpected challenge: they struggle to gain weight. Sometimes, it's because of a fast metabolism, burning many calories while participating in their sport, or combining the two. Speaking from personal experience, eating enough calories every day can be difficult. That's where mass gainers become very useful. They're calorically dense, provide plenty of protein and nutrition, and may be easier for some to consume than endless plates of solid food.

How Do Vegan Mass Gainers Differ From Those That Use Whey?

Expert
Expert

Studies show no significant differences in muscle mass gains or performance [compared to traditional mass gainers].

How Do Vegan Mass Gainers Differ From Those That Use Whey?
Vegan and traditional varieties of mass gainers are essentially the same, but there is one significant difference: their protein source. Mass gainers and protein powders, in general, traditionally use whey, a protein derived from milk. However, for various reasons (both lifestyle choices and digestive comfort included), there is a growing demand for other sources of protein supplementation.

How to Choose Vegan Mass Gainers

There are some differences between vegan and traditional mass gainers (and protein powders, too); our buying guide explains some of them and what to look for when shopping for your supplement. 
1

Look for 30g of Protein per Serving From a Quality Plant-Based Source

Expert
Expert

While exact protein needs differ depending on the individual, many vegan protein supplements provide 20-30 grams per serving.

Look for 30g of Protein per Serving From a Quality Plant-Based Source
While a big draw to mass gainers is the calorie content, the protein is the other thing that sets them apart from dirty bulking. Since athletes typically want to put on weight in the form of muscle rather than fat, supporting muscle growth with adequate protein is essential. While protein needs are individualized based on age, sex, weight, health conditions, physical activity level, and fitness goals, 20-30 grams is roughly a standard serving amount.

2

Choose the Right Type of Protein

While all vegan mass gainers use plant-based protein sources, they're not identical. Here, we'll discuss four of the most popular types of plant-based proteins.

Look for Pea Protein if you Have a Sensitive Stomach

Expert
Expert

Pea protein is easy to digest and typically well tolerated. 

Look for Pea Protein if you Have a Sensitive Stomach
Pea protein has emerged as a popular choice for individuals seeking a plant-based protein source, especially those with sensitivities to dairy or soy. Our expert consultant points out that it is unlikely to cause digestive distress. Furthermore, pea protein is rich in amino acids and low in carbohydrates. While it is a good option for those with soy and nut allergies, care should be taken for those with pea allergies.

Brown Rice Protein is Both Nutritious and Easy to Digest

Expert
Expert

Brown rice protein contains an array of amino acids and is free from major allergens.

Brown Rice Protein is Both Nutritious and Easy to Digest
Brown rice protein has become more prevalent in recent years as it is nutritionally well-rounded and easy to digest. Our expert emphasizes the amino acid content of this protein source and its being a good option for those with allergies and dietary sensitivities. While brown rice protein may not have the full range of amino acids that other options like soy or the non-vega standard whey do, it is a viable alternative many people enjoy.

Hemp Protein is Packed With Nutrients

Expert
Expert

Hemp protein contains all nine essential amino acids and is a good source of omega-3, omega-6, and fiber.

Hemp Protein is Packed With Nutrients
Hemp protein is a rich source of omega-3 fatty acids essential for heart health, brain function, and reducing inflammation. Furthermore, hemp provides extra dietary fiber compared to other sources, and, as our expert adds, it contains "all nine essential amino acids." We should note that hemp is not the most widespread protein source and is more common in dedicated protein powders rather than mass gainers.

3

Look for Complex Carbs for Sustained Energy and Better Digestion

Expert
Expert

Complex carbohydrates take longer to digest and create a more steady stream of glucose that your body can use for energy.

Look for Complex Carbs for Sustained Energy and Better Digestion
Complex carbohydrates are vital to a healthy diet, providing sustained energy and promoting optimal digestive health. Unlike simple sugars, complex carbohydrates are slowly digested, leading to a steady release of glucose into the bloodstream. Our registered dietitian has reiterated that this helps maintain stable blood sugar levels and, thus, more consistent energy levels throughout the day. Typical examples of complex carbohydrates are whole grains like oatmeal and quinoa, legumes like black and pinto beans, and starchy vegetables like potatoes.

4

Consider the Flavor

While it's not a nutritional consideration, how a mass gainer tastes is essential. While flavor is a personal preference, how you prepare your shakes can help you find the flavor that suits you best.

Look for a Simple Flavor Like Chocolate or Vanilla if You Want to Add Ingredients

Expert
Expert
Simple flavors complement most mix-ins like fruit and nut butters well. 
Look for a Simple Flavor Like Chocolate or Vanilla if You Want to Add Ingredients
If you want to add more than a few scoops of mass gainer and some water to your shake, we recommend opting for a simple flavor like chocolate or vanilla. These will pull their weight in terms of flavor and complement additional ingredients like fresh fruits. Our expert even suggests adding a bit of nut butter. A scoop of chocolate protein and some peanut butter is a classic combination and much healthier than the famous candy. Just be aware that the more you add, the more mixing you'll need.

Look for a Unique Flavor for a Standalone Shake

Expert
Expert

A more complex flavor may be most enjoyable without adding a lot of extra ingredients that may not mesh well with the flavor profile. 

Look for a Unique Flavor for a Standalone Shake
On the other hand, if all that sounds more involved than you'd prefer, we suggest looking for a more unique flavor. Something like cookies and cream or birthday cake can satisfy your sweet tooth with minimal ingredients.

Pea and Brown Rice Mass Gainer Made From Five Ingredients

Naked Nutrition makes a variety of vegan mass gainers in vanilla, chocolate, and unflavored varieties. They also offer them as standalone products or in bundles with powdered peanut butter or creatine (both of which are excellent additions to regular and mass gainer protein shakes). For our purposes today, I’ll be discussing their vanilla vegan mass gainer. It provides a 50g blend of yellow pea and brown rice protein per 1230 calorie serving, alongside 245g of complex carbs. A single serving of this mass gainer is over 60% of the standard 2000-calorie diet, which will help anyone struggling to eat enough calories to build muscle. Many non-vegan reviewers appreciated how easy this mass gainer is to digest, especially those taking greater amounts of it. They also appreciate the amino content.

Peanut Butter Flavored and Gluten Free

This mass gainer from Blessed Gainz is made with pea protein and provides 40g of protein per 290-calorie serving, thus giving it the highest protein-to-calorie ratio of any of the products included in our ranking. It also contains 150mg of berry-sourced antioxidants per scoop. Many of the reviewers mentioned enjoying the texture and flavor, both of which made it easy to mix and drink. The peanut butter flavor stands apart from the standard chocolate and vanilla that every other protein and mass gainer is available in by default. However, this flavor is still suitable for mixing with other ingredients like fresh or frozen fruits.

Common Side Effects

Common Side Effects
While vegan mass gainers are generally safe, some common side effects can occur, especially if they are not used as directed or if you are sensitive to specific ingredients. Here are some potential side effects:

  • Digestive Issues: These can include bloating, gas, and stomach cramps. Bloating is more common when first using a mass gainer or if you are sensitive to specific ingredients, such as artificial sweeteners. It can also be caused by quickly increasing your caloric intake by a substantial amount, as it may take time for your body to adjust.

  • Weight Gain: While the goal of a mass gainer is to gain weight, excessive consumption can lead to unintended and unhealthy weight gain, especially if it's primarily fat gain rather than muscle gain.

  • Blood Sugar Spikes: The carbohydrate content of mass gainers, particularly those with a high glycemic index, can lead to rapid spikes in blood sugar levels.
Report Issue with Content

Caloric Content

Caloric Content

Caloric content is a critical factor in a vegan mass gainer, as it directly influences its effectiveness in supporting weight gain and muscle growth. A high-calorie mass gainer provides the necessary energy to fuel workouts, repair muscle tissue, and create a caloric surplus, essential for building muscle and gaining weight. This is particularly important for vegans who may struggle to consume enough calories from plant-based foods alone. Individuals can ensure they meet their energy needs and support their fitness goals by opting for a mass gainer with a substantial calorie count.


Remember, if the mass gainer has fewer calories than you want, you can always add an extra scoop or two to reach your goals.

Additional Benefits of Healthy Fats Like MCTs and Omega-3s

Additional Benefits of Healthy Fats Like MCTs and Omega-3s

A well-rounded vegan mass gainer should include healthy fats to support hormone balance and overall health. Medium-chain triglycerides (MCTs) and Omega-3 fatty acids are two key types of fats that can significantly benefit the body.


MCTs are a type of saturated fat easily digested and quickly absorbed by the body. Unlike long-chain fatty acids, MCTs are directly transported to the liver, where they are used for energy or converted into ketones. Ketones can provide an alternative energy source for the brain, particularly during low-carbohydrate diets or periods of fasting. Additionally, MCTs may support cognitive function, boost metabolism, and reduce appetite. Source


Omega-3 fatty acids, particularly EPA and DHA, are essential fats the body cannot produce independently. They are crucial in various bodily functions, including inflammation reduction and brain health. Source


A vegan mass gainer containing these healthy fats can optimize your hormone balance, support overall health, and enhance your athletic performance.
