Revolutionize Your Body with Our Top Picks

1. Optimum Nutrition Serious Mass

Optimum Nutrition Serious Mass

The Optimum Nutrition Serious Mass is among the best-known mass gainers available. It includes 1,250 calories, 252 grams of carbohydrates, 200 unique vitamins and minerals for immune support, creatine, and glutamine in every two-scoop portion in addition to its 50 grams of protein per serving.

This weight gainer has a nutritional profile to help you bulk up if you have an active metabolism, a poor appetite, or just don’t have the time to eat enough calories daily. Smoothies can be supplemented with Optimum Nutrition Serious Mass to increase nutrition and calories without compromising flavor.

You may combine it with fruit in an electric blender. Do this by mixing two large scoops of powder with around 24 ounces of cold water (you can use milk as well), and then blend it with your other ingredients). The flavors of Optimum Nutrition include banana, strawberry, vanilla, and chocolate peanut butter.

Use it to help your muscles recover after exercise or to substitute unhealthy snacking in between meals. You could even sip on this before bed. It is advised to start off with half of a serving and then gradually increase the serving size over time if you are just starting out.

2. Less Naked Mass

Less Naked Mass

Less Naked Mass is a healthy and natural alternative to take into account in a market flooded with mass gainers that have a long list of ingredients. It is devoid of GMOs, growth hormones, soy, and gluten.

Also, it is manufactured without any artificial sweeteners, tastes, or colors. For 1,360 calories, 251 grams of carbs, and 50 grams of protein, there are just five ingredients. If you’d rather consume your additional calories than drink them as a smoothie, you can also utilize this mass gainer to make protein cookies or bars.

A few flavor enhancers have been added to Less Naked Mass to make the product more appetizing.

Nevertheless, unlike other “natural” products, Naked Nutrition chooses coconut sugar over stevia in their products. Although there isn’t much of a difference between sugar and coconut sugar, the latter does include a few more minerals.

Less Naked Mass should make you rather delighted if you believe that your items, and especially your mass gainers, should include as few ingredients as possible. Although it has less protein and more sugar than some of its rivals, if that’s the sort of supplement you’re looking for, then this could be right for you.

3. BSN True Mass

BSN True Mass

This is a fantastic supplement to a healthy diet and exercise regimen since it contains 210 grams of carbohydrates, mostly from rolled oats, along with branched-chain amino acids for additional nutrients. It tastes nice despite having 19g of sugar per serving. True-Mass can be used in place of meals, as a post-workout supplement, or perhaps even right before bed.

Depending on your daily protein/calorie needs, combine two scoops of the powder with 16 ounces of cool water to make one serving. True-Mass draws its protein from a variety of premium sources. They include calcium caseinate, whey protein isolate, micellar casein, milk protein isolate, egg white albumin, and whey protein concentrate. As a result, if you are a bony person, it is one of the greatest protein powders for you.

4. Naked Vegan Mass

Naked Vegan Mass

Anybody searching for a mass gainer with a formula they can actually understand, even vegans attempting to gain muscle, need to look no further. The only ingredients in this gluten-free product from Naked are pea protein powder, organic rice protein powder, and organic maltodextrin, which is manufactured from gluten-free organic tapioca.

The chocolate and vanilla flavors also have coconut sugar and organic cacao and vanilla, respectively. There are 1,230 calories, 50 grams of protein, 248 grams of complex carbohydrates, and 10.3 grams of BCAAs in each meal.

When combined with a weightlifting training regimen, Naked Vegan Mass gives your body the amino acids it requires for continuous protein synthesis and aids in muscle growth.

To effortlessly manage what enters into your body, start with the unflavored vegan mass gainer and add taste using fruit or veggies as desired. It’s ideal for both men and women who want a non-dairy weight gainer.

5. Universal Nutrition Real Gains

Universal Nutrition Real Gains

The Universal Nutrition Real Gains has an excellent nutritional profile. It is very heavy in protein and low in fat, which makes it a fantastic weight gainer supplement for athletes wishing to gain weight off-season or in order to meet weight requirements for particular classes. It can be taken as a substitute for meals or as a supplement before bed.

Given how strong the mixture is, some people may discover that taking half of a dose twice a day is preferable to taking a complete serving all at once. Just combine your preferred serving with 12 to 16 ounces of water (or another beverage of your choice) and consume it.

Around 600 calories are contained in each serving of Real Gains, which also contains inulin and digestible fiber. They supply you with a quick and continuous release of carbs and proteins, but to provide you access to more healthful nutrients, they employ MCTs and EFAs as their healthy fat sources. If you are especially thin, you will find them super handy.

Muscle Milk Gainer, one of the most well-known brands available, has 650 calories per four scoops (the suggested serving size), 32 grams of protein, and 3 grams of leucine (from milk proteins). Each serving has 110g of carbohydrates and 9g of fat, making it rather carb-heavy. This is a terrific pre-workout meal replacement due to its greater-than-average carbohydrate content.

You can also use the powder for an increase in calories and protein in smoothies or even pancake batter. Use four scoops of the powder and no more than 16 ounces of water to make a shake for the best results. A variety of vitamins and minerals are also present. It is well known that the recipe routinely produces positive results for those who work really hard to acquire weight.

7. Crazy Bulk D-Bal

Crazy Bulk D-Bal

This isn’t a bulk gainer or protein powder in the conventional sense. However, the item has to be included because it produces such fantastic outcomes (particularly for hard gainers). Similar to steroids but fully legal and without any of the negative side effects, these supplements are made to improve your body’s capacity to burn fat and build muscle. The D-Bal supplement is excellent for people who have had trouble gaining muscle mass.

The bulking stack is the way to go if you have the budget. But if not, D-Bal is a fantastic substitute. The outcomes of our recent test of their new formula are outstanding. Certainly, a balanced diet and regular exercise are necessary for the greatest outcomes with this. So, you will get fantastic results if you mix Crazy Bulk pills with one of the top muscle gainers on this list.

How to Chose an Ideal Supplement

Determine Your Needs

The first step in choosing an ideal weight gain supplement for skinny guys is understanding your needs. Your body type, known as an ectomorph in bodybuilding terms, has a fast metabolism that burns up calories and fats faster than they can be stored.

This makes gaining weight a real challenge. Therefore, you’ll need a supplement that can help you add calories to your diet, but it should also offer more than just calories. It should provide a balanced blend of proteins, carbs, and fats and should be rich in vitamins and minerals that are essential for muscle growth and recovery.

Remember that the key is not to gain fat, but to build lean muscle mass, so you must carefully examine the nutritional composition of the supplement.

Protein-Centric Supplements

Protein is the building block of muscles and, thus, a crucial component of any weight gain supplement. For skinny guys who want to gain weight, supplements rich in protein, such as whey protein or casein, can be ideal.

These provide the body with essential amino acids that are vital for muscle growth and recovery post workouts. A good weight gain supplement should offer at least 20-30 grams of protein per serving. Also, look out for the source of protein, opting for those from high-quality dairy or plant-based sources.

Carbohydrate Content


While protein is essential, you also need a good amount of carbs for weight gain. Carbohydrates provide the energy your body needs to work out and also aid in the recovery process.

Look for weight gain supplements that offer a balanced blend of simple and complex carbs. Simple carbs provide quick energy, while complex carbs offer sustained energy, helping to keep you fueled throughout your workout and throughout the day.

Healthy Fats

Contrary to popular belief, not all fats are bad. Healthy fats are an essential part of a balanced diet and are especially important for skinny guys trying to gain weight. They provide a concentrated source of energy, help absorb certain vitamins, and are important for various bodily functions. Look for supplements that include omega-3 and omega-6 fatty acids, which are good fats that help with brain function, muscle growth, and overall health.

Added Vitamins and Minerals

Weight gain supplements with added vitamins and minerals can provide a wide array of benefits. Vitamins like B6, B12, and folic acid help the body metabolize proteins and fats, while minerals like iron, zinc, and magnesium aid in muscle growth and recovery. They also ensure you get well-rounded nutrition, filling in any gaps left by your regular diet.

Avoid Unnecessary Additives

Lastly, it’s important to avoid weight gain supplements that contain unnecessary additives such as sugars, artificial flavors, and preservatives. These can lead to unhealthy weight gain and other health issues. Always opt for products with natural ingredients and minimal additives.

That is why it’s very important to know what you’re taking and to make sure that your diet is healthy and filled with all the necessary nutrients that you should take in addition to the weight gain supplements.
