How we Ranked

When we are ranking each product, there are a number of specific factors that we take into consideration.


Before we give a score for a product, we take a look at its effectiveness. This is essentially how well it does what it claims to. Every amino acid has a different level of effectiveness, and it varies wildly depending on the product. One of the things we look at is customer reviews. This gives us a better idea as to how each product works for the average person.

If you really want to find out how effective a certain product is, taking advantage of a free sample is a good idea. This will provide you with an effective means of ascertaining how well it is going to work for you in particular.


The potency of the product is something else that is very important. This is basically how strong the formula of this supplement is. We look at the quantity of each of the amino acids that make up the product’s formula. This gives us a strong indication as to just how potent it is as a whole. It is absolutely crucial that you purchase supplements that are highly potent so you can be sure they are truly effective.


Another factor we look at with these supplements is how they can be useful. Many of these supplements are helpful for burning fat as well as building lean muscle mass. We always find out how many different uses each product has before deciding on a ranking. A truly useful amino acid supplement will help you push yourself harder in your workouts while reducing recovery times.

Ease of Use

The fact is that some amino acid supplements are easier to use than others. We believe that this is a very important factor to consider prior to assigning a ranking. There are numerous things that can affect this, including the product’s taste, texture, and form. Some of these supplements come in the form of a capsule, which is very easy for most people to take. While the capsule products might be more expensive sometimes, they can be worth the expense.

There are other amino acid supplements that come in the form of a powder, which can be a little trickier. Certain powder supplements are easier to mix than others. You definitely want one that mixes well with water and a number of other liquids. This gives you a higher degree of convenience on a regular basis. The last thing you want to deal with is a product that is messy or difficult to combine, as this just makes everything more difficult.

Side Effects

Even supplements that have an all-natural formula can still come with side effects for some people. It is very important that you take this into consideration before making a final decision on a certain product. Before we rank any of these supplements, we take a look at the side effects that each one is known for.

The most common side effects with amino acid supplements include mild nausea and a jittery feeling if there is caffeine in the formula. If you are especially sensitive to stimulants like caffeine, it is better to purchase supplements that use natural ingredients to boost energy levels.

Factors to Consider

There are a number of crucial factors to consider before choosing a certain amino acid supplement. With all of the different options that are available, the following criteria will help you narrow down your options.


It is very important to look at the basic list of features for each amino acid supplement. This includes the specifics of the formula so you know exactly what is in it. Manufacturers have a tendency to modify their formulas, so you need to get this information. You need to make certain that you are getting the best product in terms of what it actually contains.


These days a lot of amino acid supplements are available in a variety of flavors. If you want to find a supplement that is compatible with you, this is a consideration to make. It’s always good to buy a product that you actually enjoy drinking. If you don’t want any flavor at all, there are plenty of these supplements that come in capsule form. This is a big factor in determining just how compatible a certain product will be with your needs and preferences.


The value of an amino acid supplement is basically what you get for the money you spend. Some of these products offer more than others, so you need to consider this before buying anything at all. Look for supplements that offer as many different benefits as possible so you aren’t wasting your hard-earned money. It’s also important to consider the number of amino acids in each of these supplements. A good value means that you will get what you pay for and then some.

Who Should Use Amino Acid Supplements?

Anyone who wants to build lean muscle as efficient as possible should consider using an amino acid supplement. These products can be very useful for those who also want to maintain a healthy weight.

Frequently Asked Questions

Should Everyone Take an Amino Acid Supplement?

As beneficial as these supplements can be, they are not right for everyone. Those who are under the age of 18 should not take them. If you are unsure as to whether or not to start on an amino acid supplement, you should talk with your physician. Some people who have serious kidney problems may also not be able to take these supplements.

What Are the Primary Benefits of Amino Acid Supplements?

Amino acids are naturally found in many foods, especially those which are high in protein. They promote strong muscles and make it easier to maintain a healthy weight. This is just one of the reasons why so many professional athletes take these supplements. One of the most significant benefits of amino acids is that they help prevent the breakdown of muscle tissue. Branched-chain amino acids or BCAAs stimulate a process known as protein synthesis. This, in turn, helps your muscle retain as much protein as possible.

What is the Difference Between Regular Amino Acid and BCAAs?

Branched-Chain amino acids consisting of valine, leucine, and isoleucine. These are all essential amino acids that the body needs to stay healthy. They play a crucial role in providing the muscles with the protein it needs to grow strong. This is why they are so popular among weightlifters. While regular amino acids are important, they aren’t quite as useful for strengthening muscles and promoting recovery as BCAAs.

What are the Consequences of an Amino Acid Deficiency?

If you aren’t getting enough amino acids on a regular basis, you could experience problems with muscle development. People with this sort of deficiency also sometimes experience problems with maintaining a healthy weight.
