Giving your body a break to focus on rapid nutrient absorption is incredibly beneficial whether it is for 1 day, 3 days, 5 days, or more. We love 3 day cleanses because it really gives your body time to finish the digestive process and allows for a few days of digestive rest and heavy nutrient and enzyme absorption. However, even a one day juice cleanse has enormous benefits. No matter how many days you know you can tackle, feel good about what you are doing for your health and for your body.
