Who Are Mass Gainers For?
Mass gainers can be beneficial for people with a fast metabolism or who have trouble eating enough calories and protein to promote muscle gain.
How Do Vegan Mass Gainers Differ From Those That Use Whey?
Studies show no significant differences in muscle mass gains or performance [compared to traditional mass gainers].
How to Choose Vegan Mass Gainers
Look for 30g of Protein per Serving From a Quality Plant-Based Source
While exact protein needs differ depending on the individual, many vegan protein supplements provide 20-30 grams per serving.
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
Pea protein is easy to digest and typically well tolerated.
Brown Rice Protein is Both Nutritious and Easy to Digest
Brown rice protein contains an array of amino acids and is free from major allergens.
Hemp Protein is Packed With Nutrients
Hemp protein contains all nine essential amino acids and is a good source of omega-3, omega-6, and fiber.
Look for Complex Carbs for Sustained Energy and Better Digestion
Complex carbohydrates take longer to digest and create a more steady stream of glucose that your body can use for energy.
Consider the Flavor
Look for a Simple Flavor Like Chocolate or Vanilla if You Want to Add Ingredients
Look for a Unique Flavor for a Standalone Shake
A more complex flavor may be most enjoyable without adding a lot of extra ingredients that may not mesh well with the flavor profile.

Common 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.
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
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.
