You should detoxify toxins from your body every 6 months. Our bodies get toxic from the food we eat and drink, from chemicals in our environment, and sometimes our bodies produce toxins. My detox of choice is called Ultraclear plus made by Metagenics. It is a medical food. I use it as a meal replacement. It is a powder I mix with 8 oz of apple juice. I take 3 shakes a day and only drink water until 2 hours after the last shake. Then I eat a healthy meal of vegetables, fruit, white rice, and/or chicken. I do this for 7 days straight. If you can't commit to 7 days, then use the shake as breakfast for 21 days.
