🍲🦴 Did you know? Bone broth naturally contains glycine and hydroxyproline, two amino acids that are important building blocks for collagen—the structural protein found throughout your cartilage, tendons, ligaments, skin, and connective tissue.
Collagen is made from repeating chains of amino acids, with glycine making up a large portion of its structure. Hydroxyproline is another distinctive collagen amino acid that helps give collagen its strength and stability.
When you consume collagen-rich foods such as bone broth, your digestive system breaks the collagen down into amino acids and small peptides. These can then be absorbed and used throughout the body, including in tissues involved in connective-tissue maintenance.
Research on collagen peptides has found promising effects on joint comfort and connective-tissue health. Clinical studies have reported improvements in joint symptoms and exercise-related joint discomfort in some people taking collagen peptides regularly, which is one reason collagen nutrition has become an active area of research.
Your body also naturally increases tissue repair and protein synthesis during sleep, making nighttime an interesting time to provide your body with the amino acids it needs for normal maintenance and recovery.
💡 Try this: Have a cup of bone broth in the evening as part of a protein-rich diet. Look for broths with a meaningful amount of protein, since the collagen content can vary significantly between products.
The fascinating part is that the humble amino acids in collagen-rich foods are the same raw materials your body uses to maintain the connective tissues that keep your joints moving smoothly.
