How We Ranked The Top Muscle Building Supplements

We had to keep a couple of essential factors to choose the supplements, as we mentioned initially. You will also have to keep those factors in mind to scrutinize the available options efficiently. And in this segment, we will talk about those factors. So, continue reading.


Before anything else, we checked the formula. Yes, we know there are no shortcuts for building muscle. But there are proven ingredients that can help with building muscle. And those elements include branched-chain amino acids, beta-alanine, creatine, protein, amino acid, leucine, and other components.

We have focused a lot on the options that include these ingredients. And the formulas that had more proven ingredients got a higher overall ranking in our list.


Just having the right ingredients does not make a muscle growth formula effective. It also needs to have the elements in the correct dosage. However, we found loads of options with proven components but at a surprisingly weak dosage. We did not even consider checking them out.

A sedentary human would require 60 grams of it per day. It should be 1.2 to 1.7 grams of protein per kilogram of body weight for active individuals. There is the proper dosage for the other elements as well. And the offerings that met this requirement got a higher position in our list.

Advertised Benefits

As we have mentioned, there is no shortcut to building muscle. You would still have to work hard and stick to a proper exercise program. However, a couple of brands will promote their supplement as a Captain America serum, which will make you bulk up overnight. But that is not possible.

So, we did not even bother testing the formulas that exaggerated the benefits. Instead, our main priorities went to the offerings that were honest about the benefits they could offer.

Taste and Mixability

Even the highly potent formula can have a horrible taste. And if you find that the drink has an unpleasant taste, you will find yourself reluctant to have it every day, which you would not want. For that reason, we have considered the taste and flavor profile. The ones that tasted good got a higher spot.

Aside from that, we even considered the texture. Usually, the formulas that had a lousy mixability offered a grainy texture. And pre-workout drinks that have a terrible texture are not enjoyable at all. So, we prioritized the offerings that have a higher mixability rate.

Value Proposition

Not all muscle builders can afford to spend tons on getting a muscle growth supplement. However, many will not even think twice to get a premium formula that will help them grow muscles quickly. But why should you pay more than you have to?

For that reason, instead of factoring in cost, we considered the overall value proposition. In this case, we checked whether the cost per serving was a good value or not. And the ones that could not provide an excellent overall value did not even make it into our list.

History of the Manufacturer

The track record of the manufacturer plays a crucial role. Want to know? Many brands will jump on the hype train to make easy money and exit the market. Usually, those brands will not offer effective or reliable formulas.

On the other hand, some brands have been around for an extended time. And through time, they have been offering nothing but a highly effective blend to the people. Those are the brands that we prioritized the most.

Complementary Ingredients

We assessed the available options based on the primary ingredients of the formula. However, different brands will integrate complementary ingredients along with the essential elements. For example, you will find branched-chain amino acids, other amino acid types, beta-alanine, and different proven components.

Those proven ingredients are there to increase the effectiveness of the formula. However, there will be some that will include random elements into the blend. Those are nothing but fillers. So, we prioritized the blends that had effective complementary ingredients instead of fillers.

Who Should Take Muscle Growth Supplements?

Anyone can benefit from these supplements because the ingredients will help with boosting energy, improving focus, and enhancing the recovery rate. However, these supplementations have a primary goal to help the body grow muscles. And these are the people that would benefit the most:

  • Bodybuilders who are trying to build lean muscle
  • Anyone trying to burn excess fat and replace it with muscle
  • People trying to get more toned, bulk up, and enhance the overall appearance
  • Someone trying to boost overall confidence, mood, and energy
  • Anyone that wants to complement a healthy diet
  • Bodybuilders who want to improve their exercise performance
  • People who want to get fast relief from post-workout soreness

Some people trying to lose excess weight will also benefit from these muscle builders. Also, people who want to increase their weight by gaining muscle can even see improvement. Each of the formulas has its purpose. So, it is always better to check the label before pulling the trigger.

The Benefits of Muscle Builders: What Science Says?

We will repeat this; there is no shortcut for gaining muscles. However, certain elements and formulas can help you achieve the goal you have been working on with so much effort. But what does science have to say regarding those elements and blends? Well, that is what we will discuss in this segment.

Whey Protein Powder

One of the best-known protein powders available to the crowd is whey protein powder. It is the protein powder that you will find in most muscle builders and protein powders. And as you might have guessed, this popular protein powder is backed by loads of research.

Usually, whey protein powder is rich in amino acids. And these amino acids will play an essential role in protein synthesis. Research also shows that the body can rapidly absorb and digest this protein powder, making it highly effective for quickly gaining muscles.


Another type of protein that is common in muscle builders is casein. It is well-known for a longer release time. In other words, the body takes a reasonable amount of time to absorb this protein. However, that does not mean that the body will struggle to digest this protein. Just the release time is extended, which is a good thing.

For example, whey protein can cause a significant spike in blood amino acid levels right after digestion. That is great if you take it right before exercising. Casein, on the other hand, is digested at a slow pace. So, it will offer the elements over the five to ten hours window.

As a result, your body will have enough resources to build muscles even after your workout. And studies have shown that the use of this protein is genuinely beneficial when it comes to gaining muscle.

However, one thing that should be in your mind is that both the whey and casein protein are from dairy sources. Such a trait makes these two unavailable to vegan bodybuilders. Considering that, many brands are opting for plant-based protein.

Even though plants are not a great source of protein, plant-based protein plays a crucial role in helping you bulk up. Take this study, for example. Here, researchers have found that the combination of rice and pea protein was equally effective as whey and casein protein in building muscles.


In the supplement space, creatine is the king of ingredients. And there is a good reason for it. It is a naturally occurring amino acid, which means it is widely available in your body. And when you take it as a supplement, it will boost muscle development and boost energy at a cellular level.

The boost of energy can help you transform your body in a concise amount of time. In creatine, there are a good number of different amino acids. It includes glycine, L-arginine, and methionine. And all of these can play a crucial role in pumping muscles and allowing more gains.

Different studies have already validated its properties. The element can boost muscle and improve strength by improving anaerobic endurance. It also does an excellent job of reducing the soreness and repairing the damage on the muscles after intense exercise sessions.


One of the most famous natural energy boosters is caffeine. It also holds power to boost muscle development. However, it works differently compared to creatine and protein. But that does not mean it is not an effective ingredient. It is the most potent element of the muscle growth formulas.

Caffeine holds the capability to improve strength, boost metabolism, promote muscle endurance, and offer many other benefits. And all of the advantages were validated by different studies.

For example, in this study, researchers have studied the effects of caffeine on people who were carrying out a single exercise program in repeat at max weight. The researchers have found that the people who took caffeine could bench press 11 percent heavier weight and leg press with 12 percent heavier weight in comparison.

They have concluded it is undoubtedly possible to push the body to the absolute limit in the gym by taking caffeine. That would eventually allow you to maximize muscle gains and strength.


Otherwise known as citrulline malate, L-citrulline is a popular ingredient in muscle builder supplements. It is an amino acid that is proven to help promote muscle gains and nitric oxide production. Now, what role does nitric oxide play? Well, it will widen up the blood vessels, which will improve the blood flow.

When the blood flow increases, physical performance increases naturally. And the benefits were validated by different studies. Take this research, for example. Researchers gave L-citrulline to the participants capable of performing 53 percent better while bench pressing.

The group also saw a 40 percent improvement in terms of muscle soreness. Other studies have shown that the element can boost aerobic performance. How? Well, through widening the blood vessels and improving the blood flow.

That said, researchers have found that this element works the best when the dosage is from 4 to 10 grams. Otherwise, its benefits are not that noticeable.


Another amino acid that has a strong link with muscle gains is beta-alanine. But what proves this statement? Take a look at this study. Researchers have found that the element allowed the participants to carry out more reps and lift higher weights.

In simpler words, beta-alanine allowed the group to enjoy a significant boost in performance and strength.


Branched-chain amino acids are another popular ingredient in muscle builders. However, there is not much scientific research that can validate its link with muscle growth. That said, BCAAs contain three amino acids. That includes isoleucine, valine, and leucine.

These can reduce fatigue, which will come in handy during intense exercise. The BCCAs also play a crucial role in minimizing the damages to the muscle. And that would boost muscle growth.

Testosterone Boosters

Different muscle builders will rely on testosterone boosters. However, like BCAAs, not many studies can validate their link with muscle boost. But when the testosterone level is max, you can surely push your body to the absolute limits. So, you will surely get a benefit from this element.

Side Effects of Muscle Builders

The elements of most muscle builders are natural. According to FDA regulations, all supplements should contain ingredients with the GRAS certification. And all of the ingredients with that certification are safe for consumption. For that reason, these do not associate with any severe side effects in the proper dosages.

That said, when you do not follow the standard dosages, you might experience these side effects:

  • Bloating
  • Indigestion
  • Stomach discomfort
  • Constipation
  • Diarrhea
  • Headaches
  • Nausea

But do note that these side effects are rare and very mild. And if you want to ensure that you do not face these, it would be better to talk to your doctor or health advisor before taking any of these supplements.

Recommended Dosages of Muscle Builders

It would be challenging to state a generic dosage for the muscle builders because each will contain elements at a different strength. So, one scoop of a particular supplement will not equal the other. In other words, you cannot compare the serving of one with the other just by considering the amount.

However, different studies did give us the required dosage for each of the essential elements. Here is a brief description of each:


The most crucial element in muscle builders is protein. And both researchers and health experts would recommend getting about 0.5 to 0.8 grams of protein per pound of body weight. That would be around 90 to 140 grams of protein for a person with an average weight.

On that note, your body would require protein to build all of the muscle. It is a must-have ingredient to rebuild the damaged muscle tissues and synthesize the muscle proteins.

Citrulline Malate

In this study, researchers have found the proper dosage of citrulline malate. Researchers have found that one should take 4 grams to 10 grams of the element to see any performance boost. That dosage range is also associated with reducing muscle soreness and muscle damages.


Another essential ingredient for muscle builders is beta-alanine. Different studies show that taking a small dose of beta-alanine can help in terms of boosting exercise performance. Studies have also shown that the body needs beta-alanine to maximize muscle growth.

Now, what small dose are we referring to here? Well, that would be from 3 grams to 6 grams. For best results, take the ingredient throughout the day instead of taking it all simultaneously.


Most of the muscle builders will include creatine in the formula. And studies show that taking 5 grams to 10 grams of the element can help to accelerate muscle development. However, you need to take the ingredient before you start working out. That would make you get the most benefits.

Frequently Asked Questions About Muscle Building Supplements

Q: How much protein should one take for muscle development?

A: The amount will highly depend on the body weight. For example, you would need to take 1.2 grams to 1.7 grams of protein per kilogram of body weight to boost muscle development. In other words, the recommended dosage for protein is 0.5 grams to 0.8 grams per pound of weight.

If you consider the average weight, 175 pounds, you need to take 87.5 grams to 140 grams of protein each day to boost muscle development.

Q: Are there different types of muscle cells?

A: Yes, three types of muscle cells include cardiac muscle, skeletal muscle, and smooth muscle. The smooth muscle is in the hollow organs, such as the stomach and intestines. You will find cardiac muscle inside the heart. That said, what most people focus on is skeletal muscles.

The skeletal muscle is throughout the hamstrings, calves, quads, and other major body regions.

Q: Is there any muscle inside the brain?

A: Not really. The brain is formed of neural tissue. But different muscle builders will indeed focus on the brain. Why? Those nootropics will help you stay entirely determined with muscle development and push your body to the max by improving focus and concentration.

Q: Can muscle builders help with soreness?

A: Good muscle builders will include elements that will help with soreness. And those ingredients will help with tissue damages that occur after intense workouts. So, if you can get one of those muscle builders, you will surely notice an improvement in muscle recovery and soreness.

Q: Is it possible to convert body fat into muscle?

A: Not really! Body fat and muscle are two different types of tissue. You cannot simply convert one into the other. That said, muscle is an active tissue that will burn calories. On the other hand, fat is a particular type of tissue that stores energy for later use.

While you are training hard, it might seem like you are replacing fat with muscle. But in reality, you will be burning fat and making the muscle tissues grow.

Q: How often should I work out to gain muscles?

A: The strength training routine would vary from one individual to another. Some people can notice serious growth in muscle training three times a week, while others would need to work out five to seven times a week. To find the perfect routine, consider talking with your fitness professional.

Q: Should I work out with free weights or machines?

A: Training with free weight and doing compound workouts will offer better results in muscle development. However, it does not mean you will not see a boost by using machines. Those will let you target specific parts, which many bodybuilders want to focus on.
