Optimum Nutrition Serious Mass Weight Gainer Protein Powder Vanilla 3 lb — 1,200+ Cal, 50g Protein

Optimum Nutrition Serious Mass is a high-calorie weight-gainer shake powder delivering large caloric intake, a 50 g blended protein dose, and abundant carbs per serving to support bodyweight and mass goals when paired with resistance training.

If you're struggling to eat enough calories to gain weight or build size, this Vanilla-flavored Serious Mass formula gives a concentrated, customizable way to add hundreds to thousands of calories to your day. Each two-scoop serving is built around a calorie-dense mix of protein, carbohydrates, vitamins, and minerals so you can tailor shakes with milk, fruit, or nut butters to match your personal calorie targets and taste preferences.

How many calories and macros does this powder provide per serving?

One typical two-scoop serving of Serious Mass supplies over 1,200 calories, a 50 g blended protein profile, and more than 249 g of carbohydrates. That macro ratio prioritizes overall energy and carbohydrate replenishment while supplying protein to support muscle recovery after workouts.

• Calories: over 1,200 per two-scoop serving (mixing medium to full-calorie liquids increases totals)
• Protein: 50 g blended protein per two-scoop serving
• Carbohydrates: 249+ g per two-scoop serving for glycogen replenishment
• Added: 20+ vitamins and minerals to round out daily nutrition

When and how should I use Serious Mass to see results?

Use Serious Mass as a post-workout shake, a between-meal calorie boost, or a bedtime supplement depending on your schedule and energy needs. Combine regular resistance training and a calorie surplus — the powder is a tool to increase intake, not a standalone solution.

• Post-workout: replenish glycogen and provide protein for recovery
• Between meals: add a high-calorie option when eating full meals is difficult
• Custom shakes: mix with whole milk, milk alternatives, fruit, or nut butter to achieve desired calories
• Consistency: use regularly alongside strength training to support gradual mass gain

What are the flavor, mixability, and customization options?

The Vanilla variant offers a neutral, versatile base that blends well with many add-ins and flavorings. Its texture is thick and filling; blending with milk or a high-speed blender improves smoothness and lets you increase total calories easily.

• Flavor: smooth vanilla base designed to pair with fruits, cocoa, or peanut butter
• Mixability: shakes best with a blender or shaker bottle and liquid of choice
• Customization: add oats, nut butter, yogurt, or frozen fruit to boost calories and nutritional variety
• Serving size: adjust powder and liquid to control texture and caloric density

What additional nutrition does Serious Mass include beyond macros?

Beyond calories, protein and carbs, Serious Mass contains more than 20 vitamins and minerals to help support overall daily nutrient intake. These micronutrients can help cover common gaps when increasing food volume for weight gain.

• Vitamins: includes Vitamin C and several B vitamins among others
• Minerals: contains zinc and other minerals to complement macronutrients
• Formulation: designed to be a more complete mass-gainer option than simple carbohydrate/protein blends
• Quality: produced by Optimum Nutrition with established quality controls

Who this is for: Serious Mass Vanilla 3 lb is intended for hard-gainers, athletes in bulking phases, and anyone who needs a reliable, high-calorie shake to increase daily intake. It's suitable for people committed to regular resistance training who want a straightforward, adaptable powder to help meet substantial calorie goals; it is not a substitute for a balanced diet and should be used as part of a planned nutrition program.
