What are the best amino acids for building muscle? This is a common question in the supplement space, especially because you can buy nearly every amino acid on its own.

Now, there are merits to supplementing with individual various amino acids, as we’ll discuss later.

But before you think about buying too many amino acid supplements ask yourself if you’re eating enough protein.

If you eat enough protein from the right sources, you’ll be 95% of the way there to getting the optimal amount of aminos acids for muscle growth.

So the short answer to the question of the best amino acids for muscle growth is all of them. Because eating enough protein is the key to building muscle.

But let’s dig deeper. While all amino acids play a role in muscle growth, some are more crucial than others, especially if you’re trying to build muscle.

In this article, we'll break down the essential amino acids, explain why branched-chain amino acids (BCAAs) are worth considering, and highlight the benefits of specific amino acids like creatine and glutamine for muscle building and recovery.

Whether you're new to lifting or a seasoned athlete, understanding how these amino acids work can help you optimize your nutrition and hit your muscle-building goals.

The Essential Amino Acids: Eat Complete Proteins

When it comes to muscle growth, the essential amino acids (EAAs) are non-negotiable. These nine amino acids cannot be produced by the body and must be obtained through your diet. The good news? If you're eating plenty of complete proteins, you're already getting all the EAAs you need. Here they are…

• Histidine
• Isoleucine
• Leucine
• Lysine
• Methionine
• Phenylalanine
• Threonine
• Tryptophan
• Valine

Complete proteins contain all nine essential amino acids in adequate amounts, making them a powerhouse for muscle protein synthesis.

Sources of Complete Protein to Get The Amino Acids You Need

Animal-Based Complete Protein

1. Meat and Poultry: Chicken, turkey, beef, and pork are excellent sources of high-quality protein and essential nutrients like iron and zinc. Make a few of these staples.
2. Fish: Salmon, tuna, and mackerel not only provide complete protein but also contain heart-healthy omega-3 fatty acids.
3. Eggs: A versatile source of complete protein, with each egg providing about 6 grams of protein.
4. Dairy Products: Milk, cheese, and Greek yogurt are rich in protein and essential nutrients like calcium.

Plant-Based Complete Proteins

1. Some soy products: Tofu, tempeh, and edamame are made from soybeans and are excellent plant-based complete protein sources.
2. Quinoa: An ancient grain that is a complete protein and can be used as a substitute for rice in various dishes.
3. Buckwheat: Another grain-like seed that provides all nine essential amino acids.
4. Hemp Seeds: These seeds are a good source of complete protein and can be added to various dishes.

Combining Plant-Based Proteins

Combining different plant proteins can create a complete protein profile, ensuring all essential amino acids are consumed. Here are some effective combinations:

1. Rice and Beans: This classic combination provides a complete protein by pairing grains, which are low in lysine, with legumes, which are low in methionine and cysteine.
2. Rice and Chickpeas: Chickpeas, or garbanzo peas, combined with rice also hits the mark.
3. Rice and Lentils: Sensing a theme? Similar to rice and beans, this combination offers a complete protein
4. Whole Wheat Bread and Peanut Butter: The combination of whole grains and legumes (peanuts) creates a complete protein. Watch out for how calorically dense this is, but it’s a great snack for hardgainers.
5. Tofu and Vegetables: While tofu is already a complete protein, pairing it with a variety of vegetables can enhance the nutritional profile[4].

These combinations are examples of how plant-based eaters can ensure they receive all essential amino acids by varying their protein sources throughout the day.

Don’t Get The Optimal Amount From Your Diet? Look Into Protein Powder

While whole foods should be your primary source of protein, protein powder supplements can offer a convenient way to ensure you're meeting your daily protein needs, especially if you're training hard.

If you’re not hitting all your protein targets, start there before going crazy with individual amino acid supplements. Once you’ve got that down, then it can make sense to look at other options.

Should You Supplement with BCAA for Muscle Growth?

When It Makes Sense to Supplement:

Branched-chain amino acids (BCAAs)—leucine, isoleucine, and valine—are particularly effective for muscle protein synthesis, making them a popular supplement choice for athletes and bodybuilders. Supplementing with BCAAs can be beneficial during prolonged exercise or fasted training.

The research on BCAAs effectiveness as a supplement is mixed. If your diet is already rich in complete proteins, you might not need additional BCAAs, but during periods of intense training or calorie restriction, they can provide an extra edge.

When It Doesn’t:

If you’re already consuming a sufficient amount of high-quality protein throughout the day, the need for additional BCAA supplementation may be minimal.

Whole foods provide a complete array of amino acids, so unless you're training in a fasted state or have specific dietary restrictions, you might not see significant benefits from BCAA supplements.

Why Choose Kaged BCAA:

Not all BCAA supplements are created equal. Some on the market are made with cheap, untested ingredients derived from sources like human hair and bird feathers. Kaged BCAAs are different. They’re 100% vegan, fermented, and non-GMO. Kaged uses a scientifically tested 2:1:1 ratio of BCAAs (L-Leucine: L-Isoleucine: L-Valine) to ensure optimal muscle recovery and growth. Plus, with rapid and complete dissolution, Kaged BCAAs mix easily into water without leaving behind any cloudy residue.

Creatine: An Amino Acid-Like Molecule

Creatine is often referred to as an amino acid-like molecule, though it technically isn’t an amino acid. It’s made from three amino acids—arginine, glycine, and methionine—and is naturally found in muscle cells.

Creatine plays a critical role in producing adenosine triphosphate (ATP), the primary energy currency of your cells, which is especially important during high-intensity exercise like weightlifting and sprinting.

Why You Should Supplement:

While your body can produce creatine and you can get small amounts from foods like red meat and fish, supplementation is the most effective way to saturate your muscles with creatine. Studies consistently show that creatine supplementation can enhance strength, increase lean muscle mass, and improve performance in high-intensity, short-duration activities. It’s one of the most well-researched supplements available, with proven benefits for both beginners and advanced athletes.

Glutamine: For Additional Recovery Support

Glutamine is the most abundant amino acid in the body, playing a crucial role in muscle recovery, immune function, and even gut health.

During intense exercise, your body's glutamine levels can be significantly depleted, which can impair recovery and immune function. While it's not classified as an essential amino acid, meaning your body can produce it, there are times when supplementation may be beneficial.

Why You Might Supplement:

For athletes engaged in heavy training or those under stress, glutamine supplementation can help support recovery. It’s particularly useful if you're training frequently or at a high intensity, as it can aid in faster recovery and help reduce muscle soreness.* Additionally, glutamine is known for its role in supporting gut health.*

Prioritize Protein To Get The Amino Acids You Need

Building muscle requires more than just hitting the gym hard—you need to fuel your body with the right nutrients, and protein is at the top of that list. By ensuring you're consuming enough complete proteins, you're giving your muscles the essential amino acids they need to grow and recover.

Supplementing with specific amino acids like BCAAs, creatine, and glutamine can help. Of the three, creatine makes the most sense for most people.

At the end of the day, your protein intake is the foundation of your muscle-building efforts. Whether you’re looking to supplement your diet with a high-quality protein powder or boost your recovery with targeted amino acids, Kaged has you covered.
