Amino acids
Amino acids are organic compounds that form the building blocks of protein, playing a key role in processes throughout the body – from tissue repair to the production of enzymes and hormones. Some are essential, meaning the body can only get them through food, while others are non-essential, and each one carries out its own specific function.
What are the benefits of amino acids?

Natural sources of amino acids
Amino acids are naturally found in protein-rich foods such as meat, fish, eggs, dairy, legumes, nuts, and seeds. Plant-based sources like soy, quinoa, and buckwheat also supply the body with important amino acids. As a supplement, they are most commonly taken in capsule, tablet, or powder form, often formulated for specific needs such as muscle recovery, mood support, or sleep quality.
Recommended amino acid intake
Recommended daily doses vary depending on the specific amino acid, as well as a person's age, sex, and activity level, but typical amounts range from 500 mg to 3 g. The right dose should be chosen individually, based on your health status, diet, and your doctor's advice.
Possible side effects of amino acids and interactions with medications
Amino acids are generally well tolerated, especially when taken with food or as a supplement within the recommended dose. Only improper use can cause digestive issues, nausea, or headaches.
Some amino acids, such as L-tryptophan or L-theanine, can enhance the effects of sedatives or antidepressants. If you are taking psychotropic medication, blood pressure medication, or have a chronic health condition, be sure to consult your doctor first.
