Many people go to the gym to lose weight, but building muscles is another popular goal. However, it’s more challenging since developing six-pack abs is a slow process. It’s hard to stay motivated when you don’t see any progress after putting in hours of strength training with your coach. 

That’s why people who want to accelerate their goals add supplements to maximize the benefits of exercise. Find out the best supplements for muscle growth and how they can help you quickly achieve your ideal body shape.

What Helps Muscles Grow Faster?

Muscles provide the strength to help you perform daily tasks efficiently. They’re essential for activities that involve lifting. Your arm and leg muscles are the reason you can carry heavy groceries or stand for hours. The stronger your muscles are, the better they are for doing tasks with ease. 

It’s essential to understand your biology to adopt the most effective ways to transform your body. There’s no denying encapsulated vitamins and compounds help promote musculoskeletal health, but what supplements are best for muscle growth? Here are seven types you can integrate into your nutritional plan. 

1. Creatine

The first thing that often comes to mind when hearing creatine is bodybuilders and athletes — and there’s a reason for it. It’s a top supplement among fitness fanatics. Creatine is a substance your body produces naturally, helping provide energy every time you lift weights or engage in strenuous exercise. It can help increase muscle mass, strength and athletic performance. 

A review of several clinical trials found that the proper dosage of creatine supplements efficiently promotes muscle growth in healthy young populations who exercise adequately. 

A different analysis looked at the effect of creatine on older women. The result concluded that a combination of resistance training and supplements led to a significant muscle strength gain in older females, especially when they exercise for at least 24 weeks. 

2. Protein

What is the No. 1 supplement for bodybuilding? If you ask a bodybuilder this question, their answer will probably be protein. Well-defined muscles are synonymous with protein. People who want to gain muscle fast often go on a high-protein diet, as this eating pattern maximizes the effects of resistance training. 

It has several functions in the body. It supports metabolism and biochemical reactions, provides energy and strengthens immunity. Protein-rich foods can naturally promote mass and strength since they’re the building blocks of muscles. The USDA recommends that women take 46 grams of protein and men consume 56 grams daily, but this changes as your age and activity level increases. It’s hard to reach the suggested numbers through diet alone, so people supplement with whey and plant-based powders. 

3. Weight Gainers

One of the best supplements for muscle growth is weight gainers, intended for those who struggle to maintain the healthy bulk necessary for muscle development. Each person has a different body type, influencing the muscle growth process. Have you noticed how it’s so easy for some individuals to lose weight while not for others? It’s similar to muscle building. 

Muscle recovery requires energy, which you get from food calories. If you burn everything during training, nothing will be left to initiate the regeneration process. Weight gain supplements increase your caloric intake, so your body has excess energy to repair muscle tears after resistance training. If you’ve been having problems building muscles, perhaps you must gain weight first. 

4. Beta-Alanine

Many people have considered beta-alanine the holy grail for muscle building, ranking it as one of the best legal supplements for muscle growth. Beta-alanine is an amino acid that affects muscle carnosine levels in the body. 

Carnosine is a naturally occurring compound found in muscles that helps buffer the pH decline in the body to keep them working. Engaging in a high-intensity workout makes muscles produce lactic acid, causing fatigue and limiting performance. Carnosine works as a buffer to reduce acidity so you can endure the workout longer. 

High levels of carnosine equals greater muscle elasticity and delayed fatigue. Beta-alanine helps increase the concentrations of carnosine in the muscles so they don’t get stressed easily, allowing you to extend your workout. 

5. Branched-Chain Amino Acids (BCAAs)

Growing muscles need amino acids created by the body or obtained through nutrition. BCAAs consist of three single amino acids — valine, leucine and isoleucine, which you can only get from eating foods such as eggs, dairy products and meat. 

BCAAs are excellent supplements for muscle growth as they stimulate protein synthesis — the process of making muscle. One study compared the effects of BCAAs and lactoalbumin — also known as whey protein — in muscle mass, strength and physical performance of patients with liver cirrhosis and sarcopenia. 

The group that took 7.2 grams of BCAA supplements for 24 weeks displayed considerable improvements in muscle strength, function and mass compared to the other group that received 6.3 grams of whey protein. Those who took BCAAs also showed fewer complications with their liver condition, proving that long-term supplementation boosted the musculoskeletal and liver health of the patient.

6. Hydroxymethylbutyrate (HMB)

The next on the lineup of the best supplements for muscle growth is HMB, also called beta-hydroxy beta-methylbutyric acid or beta-hydroxy beta-methylbutyrate. It’s a chemical the body produces when it breaks down the amino acid leucine for protein synthesis. Unfortunately, the body doesn’t make enough HMB because leucine can only be obtained through nutrition. If you don’t eat enough leucine-rich foods, your levels of HMB will naturally be low.

That’s why many fitness enthusiasts choose dietary supplements for muscle growth to increase HMB concentrations in the body. Experts cite it may benefit body composition by promoting muscle growth, reducing breakdown and improving performance in exercise. 

Sixty older adults participated in the study to determine whether 3 grams of HMB supplementation can boost the participants’ muscle mass, strength and physical performance. Researchers divided the group into two — the HMB and the control. After 12 weeks, they found the HMB group showed substantial improvement in the cross-sectional area of the mid-thigh muscle. Plus, they significantly increased their body weight and BMI, and their vitamin D levels were high. Older adults who took 3 grams of HMB supplement enhanced their mass and physical performance.

7. Omega-3 Fatty Acids

People know omega-3 fatty acids for boosting heart health, but they’re also effective supplements for muscle growth as they help increase the rate of protein synthesis. An analysis found that older adults who took more than 2 grams of omega-3 supplements gained muscle mass. Furthermore, those who received supplements for more than six months improved their walking speed, proving the positive merits of fatty acids on health and performance. 

Omega-3 fatty acids benefit functional abilities, but the body can’t synthesize them, making food the primary source of these compounds. People obtain healthy fats from seafood and fish — such as salmon, tuna and lobster — by eating at least two servings per week. However, there has been a concern about sustainable omega-3 recently, so plant-based supplements were introduced to diversify the sources.

  • Stay consistent: Building muscle is a long process, so you must be patient and stick to the routines even if you’re not seeing progress. Results will eventually come. 
  • Speak with a nutritionist: If you’re serious about strengthening muscles, talk to a professional about what your meals should look like. They may suggest adding whey protein, but ask for alternatives if you have food restrictions.
