When dealing with a bad case of body odor, it may seem like nothing but a healthy shower can make it better, but that might only be a temporary solution. If you want to get rid of body odor for a longer period of time, you may want to turn to wheatgrass, which can help to optimize your digestive system, improve your immune system, and boost circulation. As a whole, this can help to reduce the amount of toxins in your body and optimize your metabolism, either cutting down on sweating or making the sweat less potent in microbes. As a result, when you sweat, the smell of body odor is reduced!
