Best Amino Acid Supplements Reviewed
Amino acids are a compound we can’t live without. Literally. Amino acids are required for every metabolic process that occurs in the human body, and therefore are the basis of all life processes. Two of the most important functions of amino acids are the transport and storage of nutrients, such as water, fat, carbohydrates, minerals, vitamins, and proteins.
Another extremely important role of amino acids, especially for runners and other athletes, is serving as the building blocks of protein. There are 20 amino acids in total, but the human body can only produce 10 of them. The other 10 we must get through eating a healthy and balanced diet of foods that provide us with them, or else we risk the degradation of protein in our bodies.

RARI Amino Mend has 5 grams of BCAA with a ratio of 2:1:1 (Leucine/Isoleucine/Valine). Two mg of glutamine helps prevent the breakdown of muscle, and 1 mg of taurine helps regulate the flow of nutrients and water in the bloodstream.

4. Do Vitamins BCAA Capsules
Users report that they experienced quick recovery and overall increased feelings of wellness when taking this amino acid supplement. One user also mentioned that he cannot take many BCAA supplements because of a variety of allergies, but Do Vitamins BCAA capsules have not caused him any reaction, so they are really safe for people with ingestion-related sensitivities.
Even though this amino acid supplement is plant-based, it still supplies users with the 2:1:1 recommended BCAA ratio. Do Vitamins BCAA Capsules contain 1050 mg of leucine and 525 mg of each isoleucine and valine. The capsule is made of VCaps Plus, and there is a long list of ingredients these capsules do not contain, including wheat, gluten, soy, dairy, preservatives, artificial sweeteners, artificial colors, or artificial flavors.

- Easy to swallow
- No funky powder taste
- Low dose of BCAAs for some
6. Diet Standards AminoHD 1000

According to the bottle, it could range from 2 capsules to 10 capsules per day.
Since you have already read what BSN Amino X doesn’t contain, let me tell you what it does contain: 500 mg of leucine, 250 mg of isoleucine, and 250 mg of valine. Yup, you guessed it… the 2:1:1 ratio!

Some users report that they have been able to stop drinking coffee while taking Optimum Nutrition Amino Energy because it contains caffeine but doesn’t cause them to “crash” later in the day.
Two scoops of the amino acid supplement has 10 calories and 2 grams of carbohydrates. It has grams of an “amino blend,” which contains a long list of amino acids including taurine, glutamine, leucine, alanine, isoleucine, valine, tyrosine, histidine, lysine, phenylalanine, threonine, and methionine. It does not include a 2:1:1 ratio of the three main BCAAs (leucine, isoleucine, and valine) like many other amino acid supplements. The energy component of Amino Energy comes from its “Energy Blend,” which is 160mg of a combination of caffeine, green tea extract, and green coffee extract.

- One serving is 4 capsules
10. Dymatize Super Amino 6000

What is the function for amino acids in the body?
Amino acids make up the protein in food, and when we eat and digest protein, it is once again broken down into amino acids. The amino acids are then organized by our body to perform different functions, including making up most of the solid matter of the body including the eyes, skin, organs, bones, and of particular importance to runners, muscle.
Although each amino acid has a specific function and benefit to the body, the three major players for athletes are BCAAs, or branched chain amino acids. The amino acids that make up BCAAs are leucine, isoleucine, and valine. The combination of amino acids in BCAAs stimulate protein synthesis, increase cell capacity for protein synthesis, and reduce the rate of protein breakdown. So, not only are BCAAs beneficial for body builders, they are great for all athletes, even those that want to maintain a lean physique, because it helps you maintain the muscle that you have, even if you are operating on a calorie deficit.
How do amino acids benefit runners?
More specifically for runners, amino acids help your muscles recover from the wear and tear of your runs. Amino acids help repair tiny rips and tears in your muscles that happen naturally while running, helping you to recover more quickly and prevent injury. For the greatest benefit, ingest amino acids shortly after a run, through either a food-based source or a supplement. Since it is not always convenient to have food readily available, an amino acid supplement is a quick, easy, and transportable way to get amino acids into your body after a workout. Most amino acid supplements come in ready-to-mix powder form or as a pill.
If you are interested in boosting your body’s protein-related processes through the use of an amino acid supplement, you’ve come to the right place. This guide of the Best Amino Acids Supplements will give you a rundown of the top BCAAs on the market and what they have to offer you as a runner.
