9 Least Known Health Benefits of Lysine

Lysine is an essential amino acid that plays a vital role in overall health. Since the body cannot produce it, lysine must be obtained through diet or supplements. It is a key building block of proteins and is involved in various physiological functions, including immune support, collagen production, muscle growth, and calcium absorption.

Lysine is especially known for its antiviral properties, helping prevent and reduce the severity of cold sores caused by the herpes simplex virus (HSV). It also contributes to bone health, heart health, and stress management by supporting neurotransmitter function.

Found in protein-rich foods like meat, fish, dairy, eggs, and legumes, lysine is essential for maintaining good health. Whether for strengthening immunity, improving skin health, or supporting muscle recovery, lysine plays a crucial role in keeping the body strong and functioning optimally.
