You can have bone broth whenever you like! However, there are some known benefits to drinking a cup of bone broth on an empty stomach first thing in the morning. This is when your body is feeling its best and will easily absorb all the nutrients in bone broth. Likewise, a warm cup of bone broth before bed can help you fall asleep — glycine, one of the amino acids in bone broth, helps lower your body temperature and prepare your body for sleep.
