Build muscle with targeted supplements

If your goal is to add toned definition or to pack on serious mass, building muscle takes more than just time in the gym—it requires the right nutritional support. While strength training is essential for stimulating muscle growth, your body also needs the proper fuel to recover and grow stronger. That’s where muscle builder supplements can help.

At The Vitamin Shoppe, we carry a wide range of products designed to complement your workouts and support muscle recovery, endurance, and strength gains. Explore our collection of top muscle building supplements to help you reach your goals.

What are muscle building supplements?

Muscle builder supplements are designed to provide your body with the nutrients it needs to support muscle repair, recovery, and growth. These supplements often include protein powders, amino acids, creatine, and other performance-supporting ingredients.

What supplements should I take to build muscle?

The right supplement may vary by individual needs, but here’s a breakdown of some of the most popular muscle building supplements available at The Vitamin Shoppe:

  • Whey Protein Powder: A fast-digesting, complete protein that contains all essential amino acids, including BCAAs. Whey protein may support muscle recovery and protein synthesis, making it a go-to for post-workout shakes.
  • Casein Protein Powder: Known for its slow digestion rate, casein provides a steady release of amino acids. It’s often used for post-workout recoveries, like before bed to help support overnight muscle repair.
  • Mass Gainer Supplements: Ideal for those looking to increase calorie intake and build size. These supplements to build muscle mass typically combine protein, carbs, and other nutrients to help support healthy weight gain and muscle development.
  • Branched-Chain Amino Acids(BCAAs): BCAAs—leucine, isoleucine, and valine—are essential amino acids that may help reduce muscle breakdown and support recovery. They’re often included in muscle building supplement blends or taken on their own.
  • Creatine: Commonly used to support short bursts of high-intensity activity, creatine may help improve strength, power, and workout performance and may aid in muscle volume over time.

Post-workout supplements for building muscles

After intense training, your muscles need nutrients to replenish glycogen and begin the repair process. Post-workout formulas often include protein, carbs, and electrolytes to help support recovery and muscle rebuilding.

Who can benefit from supplements to build muscle mass?

Whether you're looking for muscle building supplements for men or women, most products are formulated to be effective and safe for all adults when used as directed. Your ideal supplement stack will depend on your fitness level, goals, and dietary preferences.
