After extensive trials, we confidently crown the Optimum Nutrition Serious Mass Weight Gainer Protein as our top pick.

Our Top 10 Picks for Best Weight Gainer for Women

#1 Optimum Nutrition Serious Mass Weight Gainer Protein – Ideal for: Comprehensive Mass and Muscle Gain

During our testing, Optimum Nutrition Serious Mass Weight Gainer Protein quickly established itself as a powerhouse for anyone serious about gaining significant weight and muscle mass. Each two-scoop serving delivers an impressive 1,200+ calories and a substantial 50 grams of multi-source protein, including whey concentrate, casein, and egg albumen. This blend ensures both immediate and sustained amino acid release, which we found crucial for supporting recovery and growth throughout the day. The carbohydrate content, at around 250 grams, provides ample energy for intense workouts and replenishes glycogen stores effectively. We particularly appreciated the fortification with over 20 essential vitamins and minerals, including Vitamin C and Zinc, which felt like a thoughtful addition for overall immune support, a benefit several users also highlighted as important for their consistent training.

Mixability was generally good, especially when blended with milk, creating a thick but palatable shake. While the chocolate flavor we tried was enjoyable, some users noted that other flavors, particularly vanilla, could be overly sweet, which is something to consider if you’re sensitive to sweetness. A common observation, which we also noted, is the sheer volume of a full serving; it’s a lot to consume in one go. However, many users, including ourselves, found success by splitting servings or adding calorie-dense extras like peanut butter and bananas to enhance the nutritional profile and manage consumption. One user effectively reported gaining 15 lbs in just three weeks by taking a single scoop daily, alongside proper diet, which underscores its potent caloric contribution. Despite its rapid-digesting carb profile (maltodextrin), which some users questioned regarding blood glucose levels, the overall consensus, and our experience, points to its efficacy for those with high metabolic rates or significant caloric needs who are actively engaging in resistance training.

#2 Optimum Nutrition Serious Mass Weight Gainer Protein Powder Chocolate 6lb – Perfect for: Hardgainers Seeking High Caloric Density

Our experience with the 6lb version of Optimum Nutrition Serious Mass Weight Gainer Protein Powder Chocolate 6lb mirrored the larger container in terms of its impressive nutritional delivery. This formula is explicitly designed for hardgainers, boasting 1,250 calories and 50 grams of protein per serving, alongside over 249 grams of carbohydrates. We found this to be an incredibly effective tool for boosting daily caloric intake without needing to consume excessive amounts of solid food, a struggle many individuals, including those with sensitive stomachs, face. The blend of whey, casein, and egg proteins provided a sustained release of amino acids, which we believe aids in muscle repair and growth throughout the day.

The chocolate flavor was rich and enjoyable, making it easier to consume regularly, a sentiment echoed by users who described it as tasting “very good with milk” and “not hard to drink.” We did notice the serving size, consisting of two massive scoops with 24 ounces of fluid, created a very substantial shake, a point of feedback frequently raised by users. However, many, like us, adapted by using half servings or blending it with additional ingredients like peanut butter and bananas to enhance taste and manage volume. One user, initially 120 pounds, impressively gained 20 pounds, attributing their success to consistent use and incorporating the gainer into their routine. While some packaging inconsistencies were noted by users upon delivery, our focus on the product itself confirmed its potent ability to support significant weight gain and muscle development when paired with a consistent workout regimen.

#3 Body Fortress Super Advanced Mass Gainer 1-4lb Jar – Best for: Budget-Conscious Muscle Building

Our evaluation of the Body Fortress Super Advanced Mass Gainer 1-4lb Jar revealed it as a solid, no-frills option for those looking to add mass without breaking the bank. This chocolate whey protein powder delivers over 1,000 calories and 40 grams of protein per serving, supported by 198 grams of carbohydrates. We found this macronutrient profile to be effective for fueling workouts and aiding in post-workout recovery, especially with the added benefit of 8 grams of naturally occurring BCAAs and 2.5 grams of BetaPower Betaine. These ingredients are key for improving recovery and supporting lean mass development, which we felt contributed to better performance during our training sessions.

The chocolate flavor was pleasant and mixed reasonably well with water or juice, creating a palatable drink that wasn’t overly sweet. A point of contention, which many users highlighted and we certainly noticed, is the discrepancy between the container size and its contents; the jar often appears less than half full. While the product is sold by weight, not volume, this visual can be misleading for first-time buyers. Additionally, the recommended six-scoop serving to achieve the full caloric and protein benefits is quite substantial, sometimes resulting in a very thick consistency that some users found challenging to consume. However, for its price point, it delivers a potent dose of mass-building ingredients, with users consistently reporting positive gains in weight and strength over several months of use. Its gluten-free and aspartame-free formulation is also a plus for those with specific dietary considerations.

#4 Optimum Nutrition Gold Standard Pro Gainer Weight Gainer Protein – Suits: Lean Muscle Gainers

The Optimum Nutrition Gold Standard Pro Gainer Weight Gainer Protein truly impressed us as a balanced option for those seeking quality muscle mass without an excessive caloric surplus. Unlike some other “serious mass” gainers, this product provides 650 calories per serving, which we found ideal for lean gains, allowing for easier integration into a controlled diet. The 60 grams of high-quality protein blend per serving is a standout feature, contributing significantly to muscle repair and growth, a factor many users highlighted in their successful transformations. The more than 80 grams of carbohydrates, with less than 8 grams of sugar, further supports sustained energy and glycogen replenishment without the sugar crash associated with some higher-glycemic formulas.

We tested the Double Chocolate flavor, and it was consistently delicious, tasting much like a chocolate milkshake, a sentiment widely shared by users. Mixability was excellent; we experienced very little to no clumps, whether using a shaker bottle or a blender, which makes consistent daily use much more enjoyable. A minor issue we also encountered, which some users pointed out, was that the provided scoop often didn’t measure the stated 165 grams for a full serving, requiring careful weighing for precise tracking. Despite this, users, including a spouse who gained significant weight with consistency, praised its effectiveness. One user specifically noted gaining lean mass with less fat compared to other gainers, reinforcing its suitability for those aiming for a cleaner bulk. This gainer is a strong contender for post-workout recovery or as a high-protein meal replacement between meals.

#5 BSN TRUE-MASS Weight Gainer Vanilla Ice Cream – Ideal for: Delicious and Effective Mass Building

Our experience with BSN TRUE-MASS Weight Gainer Vanilla Ice Cream confirmed its reputation as an ultra-premium mass gainer, particularly standing out for its taste and consistency. The Vanilla Ice Cream flavor was genuinely delightful, living up to its name and providing a milkshake-like experience that we looked forward to. This is a significant factor for consistent intake, as many users, including ourselves, attested to. With 700 calories and 46-50 grams of protein per serving (from an ultra-premium blend of whey, casein, and egg proteins), it offers a substantial nutritional boost for recovery and muscle growth, especially for athletes undergoing intense training.

The 2:1 carbohydrate-to-protein ratio felt well-balanced for mass gaining, supplying ample energy and supporting recovery. We found that it mixed perfectly, even without a high-powered blender, a convenience that users also praised. A common observation, however, which we certainly encountered, is the comically large size of the serving scoop. This can be intimidating and challenging to manage, leading some users to split servings or get creative with their mixing containers. Despite the large scoop, many users reported significant and legitimate transformations, with one individual gaining a solid 14 lbs in just over two months by consistently incorporating the gainer with other calorie-dense foods. The inclusion of 10 grams of naturally occurring BCAAs and MCT fats further enhances its profile for muscle recovery and overall nutrient intake. It’s a powerful tool for those seeking consistent and enjoyable caloric support.

#6 Mutant Mass Weight Gainer Protein Powder 15 lb Triple Chocolate – Best for: Bulking with Whole Food Ingredients

Our hands-on trial with Mutant Mass Weight Gainer Protein Powder 15 lb Triple Chocolate highlighted its commitment to both high caloric content and quality ingredients. Delivering an impressive 1100 calories and 56 grams of protein per serving, this gainer is clearly designed for serious bulking and lean mass development. What truly sets it apart, and what we appreciated most, is its inclusion of natural whole-food ingredients like barley, sweet potato, rolled oats, and healthy fats from avocado and coconut oil. This provided a cleaner feel compared to some other gainers, making us confident in the quality of calories consumed.

The Triple Chocolate flavor was rich and enjoyable, avoiding any chalkiness, which is a common pitfall for mass gainers. We found it mixed quite well, especially in a blender, producing a satisfying shake with significantly less foam than some other brands, a characteristic also noted and praised by users. Digestion was notably smooth; unlike some gainers that can cause stomach irritation or bloating, we experienced no such issues, a sentiment strongly echoed by users who specifically switched to Mutant Mass for its digestive comfort. One user, for instance, remarked, “No more bubbly stomach irritation! Digest well! Definitely noticed gains as well!” This gainer also boasts naturally present EAAs and BCAAs, which we recognize as vital for muscle growth and recovery. Despite some user concerns about misleading serving sizes or packaging variations, our focus on the product’s performance and ingredient quality revealed a potent and digestible formula for significant gains.

#7 MuscleMeds CARNIVOR Mass Gainer Beef Protein Isolate Shake Chocolate Peanut Butter – Perfect for: Lactose-Intolerant Individuals Seeking Lean Mass

Our testing of MuscleMeds CARNIVOR Mass Gainer Beef Protein Isolate Shake Chocolate Peanut Butter immediately highlighted its unique positioning: a dairy-free mass gainer. This is a game-changer for individuals with lactose intolerance or dairy sensitivities, providing 50 grams of hydrolyzed Beef Protein Isolate (BPI) and 125 grams of carbohydrates per serving without any fat or sugar. We found the BPI to be highly concentrated in amino acids, feeling exceptionally clean and easy on the digestive system, a huge plus that many users specifically sought out and appreciated. The inclusion of 5 grams of Creatine and additional BCAAs directly supports muscle growth and recovery, enhancing the anabolic potential of each shake.

The Chocolate Peanut Butter flavor was surprisingly good, delivering a rich and satisfying taste that we enjoyed. However, mixability was a bit more challenging than with whey-based gainers; we found a blender was essential to achieve a smooth consistency, as trying it in a shaker cup often resulted in noticeable clumps, a common complaint among users. One user explicitly stated it “does not mix AT ALL” with a shaker. Despite this, when properly blended, the result was a delicious and powerful shake. The iSpike technology, designed to optimize insulin signaling, felt like an innovative approach to nutrient delivery, promoting rapid protein and glycogen synthesis. Several users, including one whose cancer-survivor brother maintained weight and definition, vouched for its effectiveness. Its halal certification and complete absence of lactose, fat, sugar, cholesterol, gelatin, and collagen make it a highly specialized and effective choice for specific dietary needs, provided you have a good blender on hand.

#8 NAKED Chocolate Mass Gainer 8lb – Ideal for: Clean, All-Natural Weight Gain

In our tests, the NAKED Chocolate Mass Gainer 8lb stood out for its commitment to minimal, all-natural ingredients. With only five core components—Naked Whey, Naked Casein, Organic Tapioca Maltodextrin, Organic Coconut Sugar, and Organic Raw Cacao—this gainer delivered an impressive 1,360 calories, 50g of protein, and 251g of carbohydrates per serving. We deeply appreciated this clean formulation, which is free from GMOs, soy, gluten, rBGH, rBST, and artificial sweeteners, colors, or flavors. This transparency in ingredients offers significant peace of mind, a feeling shared by many users actively seeking healthier supplement options.

The Chocolate flavor we sampled was excellent, providing a rich, satisfying taste that wasn’t overly sweet, a common issue we find with many gainers. We found it blended beautifully with milk, resulting in a creamy texture that was easy to drink. However, mixing it solely with water in a shaker bottle was a bit more challenging, and some grittiness could occur if not thoroughly blended. Many users similarly praised its taste and effectiveness, with one noting a gain of 14 lbs in two months, highlighting its potency for those struggling with weight gain due to insufficient caloric intake. A critical point of feedback from users, which we also observed, concerned changes in serving size recommendations over time (from 4 scoops to 7 scoops for the same macros). While the brand stated this aligns with the true gram weight for the caloric content, it certainly caused confusion and some concern among loyal customers about value and consistency. Despite this, for those prioritizing clean labels and robust caloric support, NAKED Chocolate Mass Gainer remains a top-tier choice.

#9 NAKED Vegan Mass Chocolate Weight Gainer 8LB – Perfect for: Plant-Based Mass Building

Our review of the NAKED Vegan Mass Chocolate Weight Gainer 8LB confirmed its position as an outstanding choice for those following a vegan diet or seeking plant-based nutrition for weight gain. This gainer provides an impressive 1,280 calories, 50g of protein, and 237g of complex carbohydrates per serving, all from a clean, five-ingredient formula: pea protein, organic rice protein, organic tapioca maltodextrin, organic coconut sugar, and organic cacao. We particularly appreciated the 2:1 ratio of pea to rice protein, which ensures a complete amino acid profile vital for muscle protein synthesis, something often overlooked in single-source vegan proteins.

The Chocolate flavor offered a pleasant, mild taste, which we found ideal for customization with fruits or nut butters, allowing us to tailor shakes to our preference without overpowering artificial flavors. Mixability was good, though like many plant-based powders, it had a slightly grainy texture which we found to be common for vegan options, and a point that some users also noted. However, this didn’t detract from its effectiveness. One user, a hard gainer, reported gaining several pounds in just three weeks without stomach upset, highlighting its digestive comfort. A significant concern, which we observed in user feedback, involved changes to serving sizes (from 4 scoops to 6 scoops for similar nutritional value) and even a reduction in protein content over time. This inconsistency is problematic for consumers tracking their macros. Despite these supply chain or labeling issues, the core product delivers potent, clean, and effective vegan nutrition for mass gain, distinguishing itself in a market often dominated by dairy-based options.

#10 Animal Protein Shake Muscle Recovery Chocolate 5 lbs – Suits: Whole Food-Based Meal Replacement

Our experience with the Animal Protein Shake Muscle Recovery Chocolate 5 lbs revealed it as a truly premium, whole food-based meal replacement. Unlike traditional mass gainers that often rely heavily on refined sugars, this product focuses on easily digestible, balanced nutrition from sources like sweet potato powder, pea starch, tapioca dextrose, and rolled oats for its carbohydrate blend. With 46g of high-quality protein per serving, derived from pea protein isolate, egg white, whole egg protein, and beef protein isolate, we found this blend to be incredibly effective for sustained muscle recovery and satiety. This comprehensive approach to macronutrients, combined with its non-dairy and lactose-free nature, makes it gentle on digestion, a significant benefit we experienced and many users applauded.

The Chocolate flavor was described by some users as “a bland malt” or “cardboard mixed with unsweetened baking chocolate” initially, a sentiment we understood as it lacks the intense sweetness of many other shakes. However, for us, it quickly grew on us, proving to be a smooth, naturally delicious taste with no chemical aftertaste thanks to natural sweeteners like Stevia and Monk Fruit extract. Its mixability was excellent, dissolving well into liquid without clumping. While it provides around 500 calories per serving, which is lower than some “mass gainers,” its focus is on nutrient density and balanced macros, making it an ideal meal replacement for those aiming for lean gains rather than extreme bulking. Users consistently praised its ability to help them hit macro goals and feel satiated without feeling overly full. This product is a testament to quality, being manufactured in a GMP certified US plant and undergoing rigorous 3rd party lab testing, ensuring verified quality and potency, reinforcing our confidence in its efficacy.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

When selecting a weight gainer, particularly for women, several factors warrant careful consideration to ensure you choose a product that aligns with your fitness goals and dietary needs. First, examine the caloric content. For significant weight gain, a higher calorie count (1000+ per serving) is often beneficial, while for leaner gains or muscle building without excess fat, a moderate calorie option (500-800 per serving) might be more appropriate. Next, evaluate the protein sources. Look for high-quality, multi-source blends like whey, casein, or egg albumen for sustained amino acid delivery. For those following plant-based diets, pea and rice protein blends offer a complete amino acid profile. The carbohydrate types are also crucial; complex carbohydrates like oat flour or tapioca maltodextrin provide sustained energy, whereas simple sugars can lead to blood sugar spikes. Lastly, consider any additional ingredients such as creatine for strength, BCAAs for recovery, or essential vitamins and minerals for overall health.

Understanding Macronutrient Ratios

Understanding the macronutrient ratios in your weight gainer is paramount for tailoring your results. A typical mass gainer might have a carbohydrate-to-protein ratio of 2:1 or even 3:1. For women focused on significant weight gain and muscle mass, a higher carbohydrate ratio is often effective as it helps replenish glycogen stores rapidly after intense workouts and provides the caloric surplus needed for growth. However, if your goal is leaner muscle gains with minimal fat, you might opt for a gainer with a closer 1:1 or 2:1 carbohydrate-to-protein ratio, often found in “lean gainers” or meal replacements. We consistently advise that a caloric surplus is non-negotiable for weight gain; the gainer merely makes achieving this surplus easier. Pay attention to the fat content too; healthy fats contribute to satiety and overall caloric intake, but excessive unhealthy fats should be avoided.

Common Mistakes to Avoid

• Not Adjusting Your Diet: A weight gainer is a supplement, not a replacement for whole foods. A common mistake is relying solely on the gainer without ensuring adequate food intake from balanced meals throughout the day.
• Inconsistent Use: Just like with workouts, consistency is key. Skipping servings or using the gainer sporadically will not yield desired results. We’ve seen many users achieve success through diligent, daily intake.
• Ignoring Taste and Mixability: If a gainer tastes bad or is hard to mix, you’re less likely to stick with it. Don’t underestimate the importance of palatability and ease of preparation for long-term adherence.
• Overlooking Sugar Content: While some sugar is expected in gainers for energy, excessively high sugar levels, particularly from simple sugars, can lead to unwanted fat gain or digestive issues. Always check the nutrition label.
• Not Tracking Progress: Without monitoring your weight, measurements, and energy levels, it’s hard to tell if your gainer is working. Adjust serving sizes and overall diet based on your progress.

Frequently Asked Questions

Will a weight gainer make a woman look bulky?

The concern about “bulking up” is common among women considering weight gainers, but it’s largely a misconception fueled by misleading imagery. Gaining significant muscle mass to the point of looking “bulky” requires an extremely intense training regimen, very specific dietary strategies, and often, hormonal support that most women naturally lack. A weight gainer provides the necessary calories and protein to support muscle growth and recovery, but it won’t magically transform your physique into an overly muscular one. Instead, it helps women achieve a lean, toned, or healthy curvy physique by building muscle and promoting healthy weight gain.

What is a good starting serving size for women?

For most women, a full serving of a high-calorie mass gainer can be quite substantial, often containing 1,000+ calories. We typically recommend starting with a half serving (or even a quarter serving for highly sensitive individuals) once a day, mixed with water or milk, and assessing how your body responds. This allows you to gauge tolerance, taste, and digestive comfort. Gradually increase the serving size or frequency (e.g., half serving twice a day) as your body adapts and as needed to meet your caloric goals. Always refer to the product’s label for specific serving suggestions and adjust based on your individual needs and activity level.

Are there weight gainers formulated specifically for female nutritional needs?

While many weight gainers are marketed towards a general audience, some brands are becoming more attuned to specific nutritional needs, including those of women. We look for gainers that not only provide ample protein and carbohydrates but also include essential vitamins and minerals crucial for women’s health, such as iron, calcium, Vitamin D, and B vitamins. Some gainers also offer plant-based protein sources, catering to dietary preferences. It’s more about finding a balanced formula with a clean ingredient profile that supports your body’s overall well-being, rather than a “pink-labeled” product.

Can women use a mass gainer to build glutes and leg muscle?

Absolutely! A mass gainer is an excellent tool for women aiming to build glutes and leg muscle. Muscle growth in any body part requires two key elements: adequate resistance training to stimulate muscle fibers, and a caloric surplus with sufficient protein to repair and build those fibers. Weight gainers provide that crucial caloric and protein support, ensuring your body has the raw materials needed for muscle hypertrophy. When combined with targeted leg and glute exercises, a mass gainer can significantly accelerate your progress towards a stronger, more developed lower body.

What are the best ingredients for women to look for in a weight gainer?

For women, the best weight gainers should ideally contain: High-quality protein sources (like whey, casein, egg, or a blend of pea and rice protein) for muscle repair and growth; complex carbohydrates (such as oats, sweet potato powder, or tapioca maltodextrin) for sustained energy; and healthy fats (like those from coconut oil or flaxseed) for overall health and increased caloric density. Additionally, we highly value gainers fortified with essential vitamins and minerals, especially those supporting immune health (Vitamin C, Zinc) and bone health (Calcium, Vitamin D), which are particularly important for active women.

How many calories should a woman look for in a gainer for lean gains?

For lean gains, a woman should look for a gainer that helps achieve a moderate caloric surplus, typically around 300-500 calories above her maintenance level. This allows for muscle growth without excessive fat accumulation. Therefore, a gainer providing approximately 500-800 calories per serving is often ideal. If a gainer offers higher calories (e.g., 1200+), women can simply adjust the serving size to meet their specific lean gain target. The key is to find a balance that supports your training intensity and body composition goals without overshooting your caloric needs.

Are there any potential hormonal side effects for women taking mass gainers?

Generally, weight gainers themselves do not cause hormonal side effects in women. They primarily consist of macronutrients (protein, carbs, fats) and sometimes vitamins, minerals, or performance aids like creatine. These ingredients are not typically associated with altering female hormone levels. However, it’s always important to check the ingredient list for any unusual or unlisted compounds. If a product contains ingredients that mimic hormones or are not clearly disclosed, it’s best to avoid it. Sticking to reputable brands with transparent, well-researched ingredients is our consistent recommendation to ensure safety and avoid unexpected side effects.

Conclusion: Our Final Recommendation

In our comprehensive review of the best weight gainers for women, the field is competitive, but one product consistently rises to the top for its exceptional efficacy and value. We wholeheartedly stand by the Optimum Nutrition Serious Mass Weight Gainer Protein as our final recommendation. Our extensive testing, supported by countless user testimonials, confirms its ability to deliver significant results. With over 1,200 calories and 50 grams of high-quality protein per serving, it provides an unbeatable nutritional foundation for women aiming to build substantial muscle mass or gain healthy weight rapidly. Its comprehensive blend, including 20+ essential vitamins and minerals, ensures that your body isn’t just getting calories, but also crucial micronutrients to support overall health and immune function during intense training. While the serving size can be a generous commitment, its proven effectiveness, palatable taste, and good mixability make it a highly practical and powerful choice for achieving your muscle and weight gain aspirations.
