The 17 Best Amino Acid Supplements Reviews 2019


Is your goal to be fit? Do you want to feel better, sleep better, and build bigger muscles? Then use one of the best amino acid supplements to boost your performance.

Nine of the 20 different amino acids are essential to your health. Of these nine, none of them can be made by your body. You need to include them in your diet.

Eggs, meat, and poultry are rich in these essential amino acids. And so are amino acid supplements that allow you to increase your intake without consuming extra calories.

We selected the top supplements and reviewed them here for you. We hope our article streamlines your shopping today.

Before we begin, here’s a quick overview of those nine essential amino acids and what they do for you.

The essential amino acids

Histidine is linked to your nervous system, digestion, sleep, and sexual function.

Isoleucine is a branched-chain amino acid that affects muscle tissue, energy levels, blood cell production, and the immune system.

Leucine is another branched-chain amino acid that helps repair muscles, heal wounds, and manage blood sugar.

Lysine affects the production of collagen, elastin, enzymes, and protein in the body. It aids in absorbing calcium and maintaining energy.

Methionine is linked to tissue growth, your metabolism, and mineral absorption.

Phenylalanine affects neurotransmitters like dopamine, tyrosine, and epinephrine. It promotes the production of other amino acids.

Threonine helps metabolize fat and build elastin and collagen.

Tryptophan is essential for serotonin production, the neurotransmitter that manages your mood, appetite, and sleep cycles.

Valine is another branched-chain amino acid. It’s an important part of muscle regeneration and growth as well as energy levels.

Why take a branched-chain amino acid supplement?

Many amino acid supplements that boost exercise performance focus on branched-chain amino acids (BCAAs). That’s because they help muscles recover faster after a workout with less soreness. They also help maintain lean body mass. Even non-athletes can benefit.
