You should eat Nutrition Bar once a day, as we want people to follow a healthy, balanced diet including regular meals during the day.

You can eat it in the morning after your overnight fast or as a healthy snack anytime during the day, in addition to meals, to help curb your hunger.

The impact and safety of consuming more than one Nutrition Bar per day hasn’t been studied, and we recommend that you eat only one Nutrition Bar in the morning or evening, along with a healthy, balanced diet for your other meals.
