Technically, peptides are strings of amino acids that help make up all the proteins in our body (think: skin, hair and nails). When it comes to our complexion, these compounds mostly refer to collagen. If our peptide levels are low, wrinkles appear, nails become brittle and split ends plague our dry hair. Not to mention, after age 30, we lose one percent of our remaining collagen every 365 days (or so).Oof.
But peptides aren’t just essential to our skin. They’re crucial to every single cell in the human body because they play a huge role in how our body sends and receives messages to function properly. And, as you can imagine, if we’re deficient in them, it’s hard for our body to do what it’s supposed to (ya know, like regenerating new, healthy cells).
