People might need to gain or lose weight for personal, health, or professional reasons. These significant weight changes can be overwhelming, especially if you are expecting seamless results. This is where dietary supplements come in; these products come in various forms, including pills, powders, and liquids.
Some of the most popular products used for weight loss and gain are essential amino acid (EAA) supplements. An essential amino acid supplement aims to promote the recommended daily amino acid intake. These products contain various essential amino acids that do not naturally occur in the body.
They help in muscle protein synthesis and are beneficial in enhanced muscle growth, repair, recovery, and mass. Amino acids are considered the primary protein-building elements. Essential amino acids supplements contain the nine amino acids the body cannot generate.
They include methionine, leucine, valine, lysine, isoleucine, phenylalanine, tryptophan, threonine, and histidine. These amino acids are responsible for improving the body’s overall health. EAAs are among the most used dietary supplements for weight gain and loss. This article will comprehensively review some of the best essential amino acid supplements.
What Are EAAs?
Essential Amino Acids (EAAs) contain nine vital amino acids that do not naturally occur in the body. These essential amino acids include methionine, leucine, valine, lysine, isoleucine, phenylalanine, tryptophan, threonine, and histidine. EAAs aim to promote protein synthesis, promote muscle growth, endurance, repair, and recovery. You can also obtain EAAs from complete protein foods such as chia seeds, quinoa, eggs, fish, and meat. On the other hand, supplements are designed to boost protein intake; they come from powders, pills, or drinks.
They can help you lose weight since they contain low-calorie levels. EAA supplements also contain tyrosine, l-glutamine, citrulline malate, and other nonessential amino acids. These supplements are an excellent option, especially if you are on a calorie-restricted diet. EAA supplements can offer prominent results when combined with a healthy diet, regular exercise, and proper hydration. Also, some of these supplements contain branched-chain amino acids that can boost your overall health and fitness.
