      Meanings

      Noun

      1. an essential amino acid found in proteins

      Beyond the definition

      This isn't something you'd find on your kitchen spice rack - it's an amino acid, one of the tiny building blocks that make up proteins. Think of proteins as complex Lego castles, and this is one of the individual Lego bricks. It's called "essential" because our bodies can't make it themselves; we have to get it from the food we eat. You'll find it in foods like meat, dairy, eggs, and some plant-based sources. Without enough of it, your body can't build and repair tissues properly.

      Imagine a tiny construction worker inside you, carefully building everything from muscles to skin. This amino acid is one of the tools that worker needs to do the job well. It's not just about muscle, either; it also plays a part in immune function, collagen production, and the way the body uses fats.
