Yes, you would benefit from a body cleanse. I would stick with it for 3 months. What does you diet consist of? If you have poor eating habits I would strongly suggest that you change your diet. Over processed, fried foods can contribute to body odor as well as red meat,soda and alcohol.
Eat raw as much as possible- salads are best. Organic chicken and fish are best. If you eat red meat, buy organic grass feed beef.
