Best Supplements for Muscle Growth: Protein, Creatine, Amino Acids & More

Ask five people about the best supplements for muscle growth, and you may hear a few different answers. Common picks like protein, creatine, amino acids, and collagen each offer unique benefits, which is why the right choice depends on your specific situation.

Some help support muscle growth, some improve workout performance, and others are more focused on recovery and long-term health. Here's what to know about the most popular muscle growth supplements and how to decide which ones fit your goals.

What Are the Best Supplements for Muscle Growth?

If your goal is building muscle and you’re set on supplementation, protein powder and creatine are generally the best places to start. They're backed by decades of research, widely used, and consistently deliver results when paired with a solid training program and adequate nutrition.

That doesn't mean they're the only muscle growth supplements worth considering. 

Amino acids can be a valuable tool for recovery and preserving lean muscle, while collagen supports many of the structures that keep you active in the first place. The best supplement for muscle growth ultimately depends on your goals and where you need the most support.

Protein Powder: Best for Meeting Your Daily Protein Goals

If we could only recommend one supplement to someone trying to build muscle, protein would be at the top of the list. Most people aren't struggling because they're missing some secret. They're simply not getting enough protein to support the work they're doing in the gym.

Protein powder helps close that gap. It's easy to incorporate into your routine and can make it much easier to hit your daily target. For many people, that's the difference between getting enough consistent protein and falling short most days.

Whey protein is the gold standard for muscle growth because it's complete, highly bioavailable, and rich in leucine. Plant-based options can also work well, but we recommend aiming for a blend of protein sources rather than relying on a single plant protein.

• Top benefits: Supports muscle growth and recovery, helps you meet daily protein goals, and can support a healthy body composition.
• Who it's for: Anyone trying to build muscle, maintain lean mass while losing weight, or increase their daily protein intake.
• When to use it: After workouts, between meals, or anytime you're falling short of your protein target for the day.
• Considerations: Protein powder should supplement your nutrition plan, not replace whole-food protein sources. Opt for a whey protein with few other ingredients, and choose grass-fed if possible.

Creatine: Best for Strength, Power & Training Performance

If protein is the foundation, creatine is usually the next supplement we recommend. Few muscle growth supplements have been studied as extensively, and the research consistently shows benefits for strength, power, workout performance, and lean muscle development.

Creatine benefits also extend beyond the gym. Victory Men’s Health CEO Amy Stuttle swears by her daily dose not only for muscle and performance benefits, but also for the growing body of research linking creatine to cognitive function and healthy aging. 

Creatine monohydrate is the gold standard here, as well as the form used in the overwhelming majority of research studies. You'll see newer versions marketed as superior, but the evidence behind those claims doesn’t come close to the data we have on plain creatine monohydrate.

• Top benefits: Supports strength, power, workout performance, lean muscle growth, and may provide cognitive benefits as well.
• Who it's for: Anyone who strength trains, participates in sports, wants to improve performance and recovery, or wants to promote brain function and healthy aging.
• When to use it: Daily, including rest days. Consistency matters more than timing.
• Considerations: Some mild water retention is normal when starting creatine, and results build over time rather than overnight.

Amino Acids: Best for Recovery and Lean Muscle Support

Amino acids are arguably the most confusing category on this list. Between BCAAs, EAAs, recovery formulas, and pre-workout blends that all say “amino acids” on the label, it’s enough to make your head spin. 

Short version: amino acids are the individual compounds your body uses to build and repair muscle. Some products contain only a few amino acids, while others provide all nine essential amino acids your body can’t produce on its own. That’s where you get different formulas.

We typically think of amino acids as a recovery tool, especially for people who train frequently or are working to maintain muscle while losing body fat. We prefer a complete formula, which is why we use Body Health's PerfectAmino line. It provides all nine essential amino acids rather than just a handful of isolated ingredients.

• Top benefits: Supports muscle recovery, muscle protein synthesis, and preservation of lean muscle mass.
• Who it's for: Active adults, people focused on recovery, and those trying to maintain muscle while losing body fat.
• When to use it: Before workouts, after workouts, between meals, while fasting, or with meals that miss the mark on protein.
• Considerations: Amino acids can support muscle growth and recovery, but they shouldn't replace adequate protein intake.

Collagen: Best for Joint and Connective Tissue Health

While collagen is a form of protein, it's not a muscle-building supplement in the same way protein powder is. We think of collagen as support for the structures that help keep you active, including your joints, tendons, ligaments, and connective tissue.

Collagen often appeals to people who put a lot of stress on their bodies through training, sports, or an active lifestyle. Building muscle is important, but so is supporting the tendons, ligaments, and connective tissues that help you keep showing up for your workouts. 

When comparing collagen supplements, look for collagen peptides or hydrolyzed collagen for easier absorption. You can also find blends that include other ingredients to further support connective tissue, skin, hair, and nail health, like our Vegan Collagen + Biotin supplement.

• Top benefits: Supports joint health, connective tissue, skin, hair, nails, and healthy aging.
• Who it's for: Active adults, aging adults, and anyone looking for additional support for joints and connective tissue.
• When to use it: Any time of day. Consistency is more important than timing.
• Considerations: Collagen is not a replacement for protein powder when muscle growth is the primary goal. However, it can work as a complement to a comprehensive wellness routine or as a supportive tool for those with high injury potential.

Creatine vs. Protein: Which Is Better?

This is a little like asking whether sleep is better than exercise. Both are important, and they support your body in different ways. Protein provides the building blocks your body needs to repair and build muscle tissue, which is why adequate protein intake should be the foundation.

Creatine supports strength, power, and performance, which can make it easier to train at a higher level over time. That's one reason it's considered one of the best supplements for muscle growth. Many people also take creatine to boost cognitive function or energy production.

Which Supplement Is Right for Your Goals?

The answer depends less on the supplement and more on what you're trying to accomplish. We see people spend a lot of money chasing the latest product when what they really need is a better understanding of where their current routine is falling short.

If you're struggling to eat enough protein, start there. If you're already hitting your protein goals and want more support, creatine is usually our next recommendation. 

Training hard but not recovering well? Amino acids may be worth considering. And if your focus is supporting your joints and maintaining long-term health, collagen might make the most sense. Each supplement has its place, but you don't need all of them to make progress.

What to Look for When Choosing a Muscle-Building Supplement

Look for companies that prioritize transparency and third-party testing whenever possible. If a product promises dramatic results within days, be skeptical. The best supplements work because they're used consistently over time, not because they create instant transformations.

Products within a category can vary significantly, so it’s also important to know what you’re looking for. There are different forms of creatine, different types of protein powder, and amino acid formulas designed for everything from recovery to workout performance. 

Understanding your needs before you start comparing brands can narrow your options and make it easier to choose a supplement that actually fits your goals.

Top Questions on Muscle Growth Supplements

Can You Build Muscle Without Creatine?

Absolutely. People were building impressive physiques long before creatine supplements became popular. Creatine can help support strength and performance, but it's not required to gain muscle.

What's the Best Supplement for Muscle Growth?

For most people, protein powder is the most important supplement because muscle growth depends on adequate protein intake. Creatine is often the next best addition because of its benefits for strength and training performance.

Do Amino Acids Help Build Muscle?

Yes. Amino acids help support muscle protein synthesis and recovery. They're especially useful when recovery is a challenge, or when maintaining lean muscle during a calorie deficit or long periods of fasting.

When Is the Best Time to Take Creatine?

The best time to take creatine is whenever you'll remember to take it consistently. Daily use is far more important than whether you take it before or after a workout.
