Chromium helps the body to keep blood sugar levels balanced. People who are running low in chromium may start to crave sugary foods so this is a key mineral to get in your diet if you suffer from PMS-related cravings. It is present in lots of foods but only in very small amounts; you need to eat a wide variety of minimally processed and plant-rich meals to consume optimal daily levels. Supplement with chromium in the form of picolinate to get your levels back up to scratch.
