10 Best Supplements For Gaining Weight in 2026

With 1,280 calories and 52 grams of protein per serving, this gainer delivers the dense nutritional payload needed to push past a calorie surplus. It combines fast-acting whey and slow-digesting casein, a pairing that aims to spike muscle protein synthesis immediately after a workout and then sustain it for hours. The added gram of creatine and a suite of vitamins round out a formula designed for the individual whose primary obstacle to gaining size is simply eating enough. It’s a straightforward, calorie-forward solution for dedicated lifters struggling to meet high daily intake goals.

Each serving of this mass gainer delivers 1,280 calories and 245 grams of carbohydrates, providing a substantial volume of food in a single shake. That density can be challenging for individuals with smaller appetites to consume regularly. While the Optimum Nutrition Serious Mass Gainer container is larger in physical size, the Dymatize package offers eight servings in a more compact tub. This suits someone testing a high-calorie formula or with limited storage space.

A single serving delivers over 1,200 calories, which is the primary tool here for someone who genuinely struggles to eat enough to gain weight. This makes it a logical choice for hardgainers in a dedicated bulking phase or anyone needing to dramatically increase their daily energy intake without consuming an impractical volume of food. The inclusion of over 20 vitamins and minerals adds a layer of nutritional support that cheaper calorie sources often lack.

Its 2.0-pound container is relatively compact, so you will go through it more quickly than a bulk option like the 15-pound Mutant Mass. It is built for maximum calorie convenience, not for those seeking a minimalist or low-carb approach to weight gain.

With 1,360 calories anchored by just five named ingredients, this mass gainer is built for the minimalist who distrusts long labels. It suits those seeking a clean, substantial calorie surplus from recognizable sources like organic coconut sugar, raw cacao, and gluten-free tapioca carbs. They will also value the third-party verification of NSF certification over proprietary blends. The multi-phase protein from whey and casein provides a sustained release, which is practical for spacing out nourishment, but the formulation is squarely about fueling mass.

Each serving delivers 251 grams of carbohydrates to reach its 1,360-calorie total, a formula designed for hard gainers who need a massive energy influx to support weight gain. This high carb load is effective for fueling intense training and growth, but it demands a matching level of daily activity to avoid unwanted fat accumulation. The ingredient list keeps these calories clean, using only organic tapioca maltodextrin and coconut sugar instead of common wheat-based fillers or artificial additives.

Each 690-calorie serving provides the substantial surplus needed for weight gain, but avoids the extreme bulk of higher-calorie options like Dymatize Super Mass Gainer’s 1280 calories. Its 2:1 ratio of carbohydrates to protein delivers a balanced macro foundation for fueling workouts and recovery. The blend of whey and casein proteins offers a mix of fast and slow-digesting sources, while medium-chain triglycerides contribute an efficiently used fat source.

Compared to the Dymatize Super Mass Gainer’s 1280 calories, this product offers a more moderate calorie load per serving. This can make it easier to integrate into a daily diet without overwhelming your calorie goals. The ingredient list specifies a focused blend of multiple protein sources and carbohydrates without extensive additional compounds.

A single serving provides 1,100 calories, which directly supports the increased calorie intake needed for weight gain. This high-calorie approach suits individuals with fast metabolisms or those who find it difficult to consume enough food. The formula uses whole food ingredients like barley, sweet potato, and avocado oil for its carbohydrates and fats.

Each serving also contains 192 grams of carbohydrates, a substantial amount that requires consideration for individual dietary tolerance. The product’s container holds 15 pounds of powder, a large size that demands significant storage space.

The 1,230-calorie formula hinges on a radically transparent, five-ingredient list, making it a standout for anyone who prioritizes knowing exactly what they’re putting in their body. It’s the logical choice for strict vegans or those with dairy, soy, or gluten sensitivities who still need a substantial caloric surplus. The NSF certification adds a layer of verified trust that’s rare in the category, and the 2:1 pea-to-rice protein ratio ensures a complete amino acid profile for muscle synthesis.

The mild vanilla flavor is a blank canvas, which is perfect for the tinkerer who wants to add their own fruit or flavors, but a drawback if you prefer a rich, ready-to-drink shake. It’s a premium, specialized tool for a specific job, not a one-size-fits-all solution.

With 770 calories per serving from sources like sweet potato powder and grass-fed whey, this mass gainer provides a nutrient-dense foundation for a lean bulk. Its formula avoids artificial sweeteners and colors, appealing to users who prioritize ingredient quality. The 53 grams of protein and 110 grams of complex carbohydrates support muscle building and sustained energy, while the included 3 grams of creatine monohydrate aids recovery.

At 770 calories, it delivers a more moderate total compared to some alternatives, such as the Dymatize Super Mass Gainer with 1280 calories. This positions it for a controlled caloric surplus rather than an extreme one. The product’s focus on whole-food carbohydrate sources and grass-fed protein results in a clean, third-party tested formula.

With 60 grams of protein packed into each 650-calorie serving, the Optimum Nutrition Pro Gainer is built for adding lean mass, not just any weight. The macro split prioritizes protein over sheer caloric density, which suits a disciplined lifter focusing on muscle synthesis. It also manages to keep the sugar content surprisingly low for a product in this category. That detail matters if you’re monitoring your intake beyond just the totals.

At 650 calories per serving, Optimum Nutrition Pro Gainer sits at the more moderate end of the mass gainer spectrum, delivering a substantial but not extreme calorie load. For comparison, the Dymatize Super Mass Gainer provides 1280 calories per serving. This positions Pro Gainer as an option for those seeking a significant calorie increase without the highest available totals.

With a 6:1 carb-to-protein ratio delivering over 1,220 calories, this is a formula designed for one thing: adding bulk fast. It’s for the hardgainer who struggles to eat enough, where every calorie counts and a high-carb load is the primary goal. The inclusion of creatine monohydrate is a pragmatic touch for supporting training intensity, and the fact it’s made in a certified facility offers some peace of mind in a category not known for transparency. This is a tool for a specific phase, not a daily protein shake.

It’s a straightforward, no-frills approach to weight gain. For someone whose main barrier is sheer caloric intake, this ratio is the point. If your primary focus leans more toward maximizing protein intake per calorie, something like the Transparent Labs Mass Gainer, with its different macro split, would be a more logical comparison to run the numbers against.

With 1,010 calories and 64 grams of protein in a single serving, this is a tool for adding serious mass as efficiently as possible. Its 3:1 carb-to-protein ratio and blend of slow-digesting carbs like sweet potato and oats are designed to fuel intense training and recovery without a sugar crash. That makes it a logical choice for dedicated athletes struggling to eat enough calories from whole foods alone. It’s a focused formula, and the inclusion of 20 vitamins and minerals rounds out the nutritional profile in a way that matters when you’re pushing your body hard.

ALLMAX QUICKMASS delivers 1,010 calories per serving, so it’s designed for significant mass gain rather than a light post-workout drink. For someone with a smaller appetite or more moderate goals, that caloric density can be overwhelming. The formula is clinically studied to boost fat-free mass, positioning it for serious athletes focused on lean muscle. If your priority is a giant container for long-term value, the Mutant Mass offers a 15-pound tub.
