Adding size means adding calories, but drinking a thousand-calorie shake that tastes like chalk or upsets your stomach is a fast way to abandon the plan. Many mass gainers pack in sugar alcohols or cheap fillers that make the calorie count look impressive while making the actual drinking experience miserable.
A protein shake for weight gain should deliver a meaningful calorie boost from quality sources, mix smoothly into a daily routine, and actually taste like something you would choose to drink. I looked at the Best Protein Shakes For Weight Gain to find the ones that balance a substantial calorie load with a formula you can stick with.
My overall pick for best protein shakes for weight gain is the Premier Protein 30g High Protein Shake, Chocolate. It provides a straightforward, ready-to-drink option with a balanced macronutrient profile and low sugar, making it easy to incorporate consistently. My top picks are just below.

This Premier Protein shake delivers a substantial 30 grams of protein in an 11-ounce ready-to-drink bottle, anchored by its award-winning chocolate flavor. I see this working best for someone needing a convenient, high-protein snack without the prep time of a powder.
The formula includes 24 added vitamins and minerals, including 50% of the daily value for calcium and 30% for Vitamin D, which helps frame it as more than just a protein source. However, these doses are supplemental, not complete replacements for a multivitamin.
The main trade-off is the single-use packaging. While the brand notes a redesigned, easier-to-recycle PET bottle, it still creates more waste than a reusable shaker with bulk powder.
Dymatize Super Mass Gainer is a high-calorie weight gainer powder delivering 52g of protein and 1280 calories per serving. Its formula blends whey and casein for sustained protein delivery.
Pros
- +Substantial 1280-calorie serving for aggressive mass goals
- +Dual-protein blend for fast and sustained amino acid delivery
- +Includes 1g creatine monohydrate to support training output
Cons
- −Massive 245g carbohydrate load per single serving
- −Only eight servings in the 6-pound container
- −Vanilla flavor limits customization without added ingredients
Key Facts
Detailed Review
This is a high-calorie weight gainer built around a single, substantial serving containing 1280 calories and 52g of protein. The formula combines fast-digesting whey with slower-digesting casein, which I see as a practical approach for sustained amino acid delivery over several hours.
The trade-off for that caloric density is a massive 245g of carbohydrates per serving, which will suit those with very high energy demands but may be excessive for others. I'd consider this a reasonable pick for individuals struggling to meet extreme caloric surplus targets through whole food alone.
With only eight servings per container, it's geared toward a short-term trial or very focused mass-gaining phase rather than a long-term staple.
This is a vanilla-flavored, calorie-dense nutrition drink mix designed to help support weight maintenance. It offers a blend of carbohydrates, protein, vitamins, and minerals.
Pros
- +Explicitly formulated for healthy weight maintenance support
- +Designed for integration into active, demanding lifestyles
- +Mixable format adaptable to between-meal or on-the-go use
- +Over 100 years of brand history in nutrition
Cons
- −No specific protein or calorie dose per serving disclosed
- −Lacks third-party testing certification for ingredient verification
- −Vanilla flavor may not suit all taste preferences

Detailed Review
Naturade's Weight Gain Nutrition Drink Mix is a vanilla-flavored powder positioned for healthy weight support. I see this working best for active individuals or those with busy schedules who find it challenging to meet calorie needs through food alone.
The product is described as a calorie-dense blend of carbohydrates, protein, vitamins, and minerals, avoiding "extreme bulking formulas." It's designed for flexible use between meals or blended into smoothies.
My main assessment is this offers a straightforward approach, but the label lacks a disclosed protein or calorie dose per serving for precise planning. I'd consider this a reasonable option for general nutritional supplementation when more calories are needed.
This is a ready-to-drink strawberries and cream protein shake providing 30g of protein per serving. It includes 24 vitamins and minerals with 1g of sugar and 160 calories.
Pros
- +High 30g protein dose in a single portable serving
- +Complete essential amino acid profile included
- +Low sugar content of just 1 gram
- +Fortified with 24 vitamins and minerals
Cons
- −No third-party testing or certification disclosed
- −Shelf-stable format may not appeal to fresh-ingredient purists
- −Pack of 12 requires significant storage space
Key Facts
Detailed Review
Premier Protein's Strawberries & Cream shake delivers a straightforward 30 grams of protein in an 11-ounce, ready-to-drink bottle. I see this as a practical choice for someone prioritizing convenience and a significant protein hit over whole-food sources, especially with its 1 gram of sugar and 160-calorie count.
The formula includes all essential amino acids and is fortified with 24 vitamins and minerals, such as zinc and vitamins C and E. This positions it more as a nutrient-dense meal replacement or recovery drink than a simple protein supplement.
Worth knowing before you buy is that the product lacks any disclosed third-party quality verification. I'd consider this shake best for routines where grab-and-go convenience is the top priority, and the taste profile aligns.
This is a ready-to-drink nutritional shake providing 530 calories and 22 grams of protein per 8-ounce serving. It also includes 26 vitamins and minerals for general nutritional support.
Pros
- +High calorie count in a single 8-ounce serving
- +Complete nutritional profile with vitamins and minerals
- +Convenient, pre-mixed liquid format
Cons
- −Significant volume for bulk purchasing and storage
- −Thick texture may require dilution for some preferences
- −Packaging waste from 24 individual bottles

This BOOST Very High Calorie drink delivers 530 calories in an 8-ounce chocolate-flavored serving, one of the highest calorie densities I see in ready-to-drink formats. Each bottle contains 22 grams of protein and is fortified with 26 vitamins and minerals, providing a broad nutritional base. I'd consider this for routines where maximizing calorie intake from a liquid source is the primary goal.
The chocolate flavor and thick texture are designed to make a high-calorie product palatable, though the description notes you can drink it over ice if you prefer it less thick. The main trade-off is the physical bulk: a case of 24 eight-ounce bottles requires considerable storage space.
I see this working best for situations demanding convenient, concentrated calories, where mixing powders isn't practical. It's a straightforward nutritional tool built around a specific calorie target.
This is a ready-to-drink protein beverage providing 30g of protein per 11oz bottle. It also includes 24 vitamins and minerals.
Pros
- +High 30g protein dose per single bottle
- +Convenient, no-prep ready-to-drink format
- +Added micronutrient support from 24 vitamins and minerals
- +Low sugar content at just 1g per serving
Cons
- −Single-serving TetraPak generates more packaging waste
- −No third-party testing or certification disclosed
- −Multi-pack only, no option to purchase a single bottle

Premier Protein's shake delivers 30g of protein in an 11oz ready-to-drink bottle, a high dose for this format. I'd consider this for someone who needs a convenient, no-mix option post-workout or as a meal replacement. The chocolate peanut butter flavor is a specific taste profile, which may not suit everyone.
Beyond protein, it includes 24 vitamins and minerals, with notable amounts of calcium and vitamin D. This moves it beyond a simple protein source into more of a fortified beverage. The main trade-off is the single-use TetraPak packaging, which is less sustainable than a powder you can mix yourself.
I see this working best for an on-the-go routine where convenience outweighs other factors, or for those following keto or bariatric diets where the low sugar and carb counts are a priority.
Core Power Elite is a lactose-free protein drink providing 42 grams of protein per 14oz bottle. It contains all nine essential amino acids and is shelf-stable.
Pros
- +High 42g protein dose per single bottle
- +Lactose-free for easier digestion
- +Convenient, ready-to-drink shelf-stable format
Cons
- −Single-serve bottle generates more packaging waste
- −Bulk 12-pack requires significant storage space
- −Chocolate flavor is the only disclosed option
Key Facts
Detailed Review
This Core Power Elite shake delivers a substantial 42 grams of protein in a single 14oz serving, a dose that stands out for post-exercise refueling. The formula is lactose-free and made from ultra-filtered milk, which I'd consider a practical choice for those seeking dairy protein without digestive discomfort.
The ready-to-drink, shelf-stable bottles offer clear convenience but come with the trade-off of single-use packaging. I see this working best for someone prioritizing a high, immediate protein intake from a portable source over a powder they'd mix themselves.
Buying Guide for Weight Gain Shakes
A weight gain supplement works when its calorie density comes from usable sources and it fits into your existing meals without causing digestive distress. A few practical details separate a useful tool from a sugary bulk powder.
Calorie source and quality
The total calories per serving matter, but where they come from matters more. Look for a balance of protein, complex carbohydrates, and healthy fats instead of a formula dominated by sugar or sugar alcohols, which can cause bloating.
Some powders use maltodextrin or excessive fructose to spike the calorie count, which delivers energy quickly but may not support sustained nutrition. A blend that includes oats, protein isolates, and moderate fats tends to be gentler and more versatile for mixing into a daily protein routine.
Protein blend and absorption
Weight gain is not just about calories; it is about supporting lean tissue. A protein shake should provide a complete amino acid profile from sources like whey, casein, or a plant-based blend. The specific protein types affect how long the amino acids remain available.
Fast-digesting whey isolate is useful post-workout, while slower-digesting casein or milk protein blends can provide a sustained release. A product that combines both offers a timed-release effect, which can be practical for spacing out nutrient intake across a busy day.
Digestive compatibility and additives
High-calorie shakes often include thickeners, artificial sweeteners, or lactose that not everyone tolerates. Checking the label for lactose-free formulations, gluten-free certifications, or the absence of specific sugar alcohols like xylitol or sorbitol can prevent unwanted side effects.
If you have a sensitive stomach, a powder with simpler ingredients and a moderate fiber content is often easier to incorporate than a formula loaded with proprietary blends and digestive enzymes. Starting with a half-serving to assess tolerance is a sensible approach.
Format and routine fit
Your consistency depends on convenience. Ready-to-drink shakes are portable and require no preparation, ideal for keeping in a bag or at a desk. Powder formats offer flexibility to adjust the serving size and blend them into smoothies with fruits, nut butter, or oats for extra calories.
The right format is the one you will actually use daily. A powder that clumps no matter how you mix it or a pre-made shake with an artificial aftertaste will likely end up unused. Taste and mixability are functional features, not just marketing points.
Once you know the calorie source, protein quality, and how a product fits your digestive tolerance and daily schedule, the choice narrows to one or two clear options. The goal is a sustainable addition, not a temporary challenge.
Why You Should Trust Us

Final Thoughts
Choosing a protein shake for weight gain comes down to finding a calorie-dense formula from quality sources that you can take consistently without digestive issues. The products that stand out offer clear labeling and a macronutrient balance designed for addition, not replacement.
For most people looking to add a reliable, ready-to-drink option to their routine, the Premier Protein 30g High Protein Shake, Chocolate works as the best overall choice. It provides a substantial protein hit with low sugar and a balanced nutrient profile in a convenient format. If your priority is caloric density for intense mass gain, the Dymatize Super Mass Gainer Protein Powder delivers a high-calorie serving from a blend of proteins and carbohydrates, suitable for post-workout recovery or as a meal supplement.
The right product removes the guesswork from adding calories, letting you focus on your routine instead of the label.
FAQs
When is the best time to drink a weight gain shake?
A weight gain shake can fit after a workout to support recovery or between meals as a calorie-dense snack. Timing depends on your total daily intake and tolerance; having one with a meal can help manage fullness if drinking it alone is challenging. Consult a dietitian or doctor if you are managing specific health conditions related to nutrient intake.
Do you need a mass gainer if you eat regular meals?
A mass gainer is designed for individuals who struggle to consume enough calories through whole foods alone due to appetite, metabolism, or a highly active lifestyle. It is a supplemental tool, not a necessity, and works best when added to a balanced diet rather than replacing meals.
Can a high-calorie shake cause stomach discomfort?
Some high-calorie shakes, especially those with sugar alcohols, excessive fiber, or thickeners, can lead to bloating or gas. Starting with a half-serving and ensuring you mix the powder thoroughly can help gauge your individual tolerance. Choosing a product with a simpler ingredient list often reduces this risk.
How do you choose between a ready-to-drink shake and a powder?
A ready-to-drink shake offers maximum convenience for on-the-go use with no preparation, while a powder allows you to customize the serving size, calorie content, and flavor by blending it with other ingredients. Your decision should hinge on which format you are more likely to use consistently as part of your daily routine.
