Interesting Fact
L-Lysine: An Essential Amino Acid You Can’t Make Yourself
L-Lysine is considered an essential amino acid, meaning your body cannot produce it on its own—you must get it from your diet or supplements. Foods like eggs, meat, dairy, and some legumes are great sources. L-Lysine is vital for building proteins and supports natural collagen production, making it an important part of your daily nutrition.
