10 Best Mass Gainer For Teens 2025 in the United States

Optimum Nutrition Serious Mass Weight Gainer Protein Powder is designed for those looking to gain weight, making it particularly suitable for teens who are active or may struggle to consume sufficient calories. With a substantial 1,250 calories per two-scoop serving, it provides a high-calorie option to support weight gain. The protein content is impressive at 50 grams per serving, which is crucial for muscle growth and recovery, while the over 250 grams of carbohydrates help replenish energy levels after workouts. Additionally, it includes 25 vitamins and minerals, along with creatine and glutamine, enhancing its nutritional profile.

A significant advantage of this product is its versatility. You can blend it with fruits, peanut butter, or other calorie-dense foods to further boost your intake, making it easier to reach your weight gain goals. The vanilla flavor is quite popular.

On the downside, the high caloric and carbohydrate content may not be suitable for everyone. Teens who are not engaging in rigorous physical activity might find it leads to unwanted weight gain rather than healthy muscle mass. Furthermore, the digestibility could be a concern for some users, as the richness may lead to discomfort if consumed too quickly or in large amounts. The product also has a warning about exposure to heat or sunlight, indicating that it requires care during delivery. This could be a drawback for those living in warmer climates or for online shoppers who may not be available during delivery.

The Mutant Mass Weight Gainer Protein Powder is a solid choice for teens aiming to gain weight and build muscle. With an impressive 1,100 calories per serving, it provides substantial caloric content necessary for bulking. The protein content is also noteworthy, containing 56 grams of high-quality protein derived from a blend of whey isolate, concentrate, and casein, which helps in muscle recovery and growth. The inclusion of 192 grams of clean carbohydrates and 12 grams of fat adds to its effectiveness as a mass gainer by providing sustained energy and promoting healthy weight gain.

One strong point is the formulation using natural whole foods like sweet potato, rolled oats, and avocado. This can be particularly appealing to health-conscious teens and parents who prefer products with less artificial ingredients. The product also includes essential amino acids (EAAs) and branched-chain amino acids (BCAAs), which further supports muscle growth and recovery.

With 15 pounds of product, it may not be the most convenient for all users, especially those who are new to supplements or just starting their fitness journeys.

The Mutant Mass Extreme Gainer is designed for teens who are hard gainers and looking to significantly increase their muscle size and strength. One of its strongest features is its high caloric content, delivering 1,270 calories per serving when mixed with milk, which is ideal for those needing extra calories to gain weight. Each serving also boasts 46 grams of protein, making it a solid option for muscle recovery and growth, alongside 255 grams of carbohydrates that fuel workouts and replenish energy. The inclusion of healthy fats, such as those from coconut oil and avocado, adds to its nutritional profile while still keeping the fat content moderate at 7.5 grams per serving. The use of natural whole foods like barley and sweet potato is a commendable aspect, promoting a cleaner source of calories compared to many other weight gainers.

There are a few drawbacks to consider. The requirement of mixing four scoops with two cups of milk might be overwhelming for some teens, making the shake quite hefty and difficult to consume all at once. Additionally, the high caloric and carbohydrate content may not suit everyone, especially those who have lower energy needs or are looking for a more balanced approach to nutrition.
