It’s not often we as a society discuss purposefully gaining weight rather than losing weight, but there are situations in which it is appropriate to do so. Eating a well-balanced diet and exercising consistently are key parts of a healthy lifestyle and routine, and should yield a fairly consistent weight. There are a lot of factors beyond your weight that contribute to your health, and being thin is not necessarily a sign of overall vitality. You can be thin but lack certain vitamins and minerals, or bulked up on steroids without fueling your body with healthy fats. Sometimes people find themselves underweight due to a number of potential underlying conditions, or are interested in bulking up in the gym and need a way to safely supplement their diet. This is where mass gainer supplements come in.

What Are Mass Gainer Supplements?

First off, I am not a healthcare professional, nor am I a fitness or nutrition expert. This article is purely meant to spark interest, any health decisions about adding or subtracting supplements from your diet should be done alongside your doctor. That being said, if you want to get swole in the gym mass gainers are a great way to do it. Additionally, if you need to put on some weight post-surgery or health scare — they’re an efficient way to do it without stuffing your face with nachos and donuts. Mass gainers tend to be made with a mix of healthy fats, proteins and carbohydrates that are concentrated, so you get more calories from them than you would a standard meal or protein shake. They’re a healthier way to gain weight rather than overindulging on fattening foods, and provide a relatively clean energy source for your body to use. Let’s walk through a few of the options out there and explore what’s worth noting about each one. Here are the best mass gainer supplements for 2021.


1. Optimum Nutrition Mass Weight Gainer


This Optimum Nutrition mass gainer supplement has over 35,000 (!) reviews on Amazon and an average rating of 4.5/5 stars so you know it’s good. Each two-scoop serving has 1,250 calories and 50 grams of protein for fueling intense workouts and helping your body build muscle post-lift. This blend also has Vitamin C, Zinc, Vitamin D for immune support and Vitamin E. Each serving also has over 250 grams of carbohydrates for some easily accessible energy, and the mix of 25 vitamins and minerals also contains creatine and glutamine — two excellent substances for recovery. This powder is easy to mix into smoothies, shakes or even overnight oats and at less than $50 for a 12-pound bag it’s also one of the most affordable mass gainer supplements we found.

4. Dymatize Super Mass Gainer Protein Powder


This mass gainer supplement powder comes out to $0.26/ounce, a bargain compared to other options, but still packs a powerful punch with 1,280 calories per serving, 52 grams of protein, 10.7 grams of branched chain amino acids and 5.1 grams of Leucine that aids in muscular protein synthesis.

5. MuscleMeds Carnivor Mass Diet Supplement


Reviewers raved about the taste of this MuscleMeds chocolate fudge mass gainer supplement. It’s a 100% beef protein isolate weight gainer, so if you’re vegan you’ll probably want to opt for another option. It has over 700 calories per serving, as well as 50 grams of protein, 125 grams of carbs and low fats as well. It’s not as concentrated as other options, so if you’re looking for a protein powder/mass gainer hybrid it’s a good choice. The perk of using beef protein? It’s easier on the stomach through being lactose, sugar, dairy and gluten-free. Beef protein is also capable of delivering high concentrations of amino acids for rapid absorption fast.

12. Genius Muscle Builder Growth Optimizer for Men & Women


This mass gainer powder costs a bit more than others on this list, but comes formulated with three different clinically-studied ingredients. It’s made with Peak02, a certified-organic Ayurvedic mix of six different mushroom strains that supposedly help with power and endurance, and decreasing exhaustion. It also contains ingredients HMB and Vitamin D that, when combined, are formulated to help decrease muscle protein breakdown, build lean muscle, improve muscle function and strength, help with mobility and aid in faster recoveries as well. All of this scientific backing leads to a higher price tag, but if you’re willing to spend a bit more it may be a worthwhile investment.
