5 Things You Should Know About Amino Acids

Have you heard the expression “you are what you eat”? Well, it couldn’t be truer regarding amino acids. These building blocks of protein are essential for many processes in the human body, from muscle building to hormone production. In this article, we take a closer look at amino acids and how they play a crucial role in maintaining good health. Thus, whether you’re into fitness or simply curious about nutrition, keep reading to understand the relevance of amino acids in our daily life.

What is an amino acid?

Amino acids are the foundation of protein, an important macronutrient required for tissue growth, maintenance, and repair. Amino acids are made up of a core carbon atom, an amino group (-NH2), a carboxyl group (-COOH), and a side chain or R-group that varies amongst amino acids and gives them their distinct chemical properties. Proteins contain 20 different amino acids, which are classified as either essential or non-essential.

The essential amino acids are those the human body cannot synthesize and must get from diet. Among them are histidine, leucine, isoleucine, lysine, phenylalanine, methionine, tryptophan, threonine, and valine. In contrast, the body can produce non-essential amino acids and does not require supplementation.

Amino acids can be visualized through an amino acid chart, as the structures affect their properties. This chart is commonly used in the study of nutrition and biology to help understand the role amino acids play in the human body. The amino acid chart helps identify which amino acids are essential and non-essential and understand each amino acid’s chemical properties and functions.

Amino acids are essential for muscle growth and repair.

Amino acids are like bricks forming the foundation of proteins, essential for building and repairing muscle tissue. When we engage in physical activity or exercise, our muscles experience small amounts of damage or “micro-tears.” These micro-tears are a natural part of the muscle-building process, as our muscles repair and rebuild themselves to become stronger and more resilient.

For this repair process to occur, our bodies need a ready supply of amino acids to use as building blocks. When we consume protein-rich foods like meat, fish, dairy products, and soybeans, our bodies break down the protein into its amino acid components. These amino acids are transported to the muscles to repair damaged tissue and promote muscle growth.

Leucine is an amino acid that is particularly crucial for muscle growth. Leucine is one of three branched-chain amino acids (BCAAs) that can accelerate muscle protein synthesis or construct new muscle tissue. This is why many athletes and bodybuilders take BCAA supplements or consume foods high in leucine to help with muscle building and recovery.

Amino acids can aid in weight loss.

Amino acids can aid in weight loss by reducing appetite and increasing metabolism. Amino acids can help you feel full and satisfied after a meal, helping you reduce overall food intake to stay in a calorie deficit.

Certain amino acids can increase metabolism, i.e., the rate at which your body burns calories. For example, the amino acid leucine can increase energy expenditure and promote fat loss. Moreover, other amino acids like lysine and arginine can improve insulin sensitivity and glucose metabolism, aiding in weight loss.

Amino acids can also help preserve muscle mass during weight loss. When we lose weight, we lose fat and muscle mass. However, adequate protein and amino acids can help maintain muscle mass and promote fat loss, leading to a leaner and healthier body composition.

Amino acids can improve brain function.

Amino acids can improve brain function by serving as building blocks for essential neurotransmitters, the chemical messengers that allow nerve cells to communicate. Certain amino acids, such as tryptophan, tyrosine, and phenylalanine, are precursors to neurotransmitters like serotonin, dopamine, and norepinephrine. These neurotransmitters are crucial in regulating mood, memory, and cognitive function.

For example, serotonin is known as the “feel-good” neurotransmitter and is involved in regulating mood, appetite, and sleep. Tryptophan, an amino acid found in foods like turkey, eggs, and cheese, is a precursor to serotonin and can help boost mood and reduce symptoms of depression and anxiety.

Dopamine is involved in feelings of motivation, reward, and pleasure. Tyrosine, an amino acid found in foods like chicken, fish, and almonds, is necessary for dopamine and can help improve cognitive function, memory, and attention.

Amino acids also regulate blood flow and oxygen delivery to the brain. Arginine, an amino acid found in foods like nuts, seeds, and meats, is a predecessor to nitric oxide, which assists blood vessels in relaxing and improving blood flow to the brain, improving cognitive function, memory, and overall brain health.

Amino acids can boost immune function.

Amino acids help boost immune function by supporting the production of vital immune cells and antibodies. These essential building blocks of protein are necessary for synthesizing the proteins that form immune cells and antibodies, which help our bodies fight infections and diseases.

Glutamine is an amino acid that plays a vital role in immune function by promoting the growth and activity of immune cells such as lymphocytes and macrophages. It also helps preserve the intestinal lining, a crucial barrier against toxins and pathogens.

Arginine, another amino acid in nuts, seeds, and meats, enhances immune cell activity and promotes wound healing. It also aids in producing nitric oxide, which has antimicrobial properties and can help defend against infections.

Amino acids can amino acid improves skin and nail.

Amino acids can contribute to healthy skin and nails. Amino acids are essential for producing collagen, the main structural protein in skin, hair, and nails. Collagen provides strength, elasticity, and hydration to these tissues, and a lack of amino acids can lead to a breakdown in collagen production and weaken skin and nails.

The amino acids proline, glycine, and hydroxyproline are essential for collagen synthesis and are typically present in collagen supplements and skincare products. These amino acids can help improve skin elasticity, hydration, and firmness and promote healthy nail growth.

Methionine and cysteine are essential amino acids for promoting healthy hair, skin, and nails. They are necessary to produce keratin, a protein that gives hair, skin, and nails strength and durability.


Amino acids are essential for overall health and well-being, helping build muscle, promote weight loss, improve brain function, boost immunological function, and support various other bodily activities. Essential amino acids are vital because the body cannot synthesize them and must receive them through diet. Knowing the properties of amino acids can help people make informed food and lifestyle decisions that will benefit their health and well-being.
