Ronbn49 is right. Your detoxing and detoxing burns lots and lots of energy. I see people post all the time asking why they have this symptoms or that on detox supplements. MSM, NAC, Glutathione, Selenium, Zinc, Black Radish, Reishi, Capryl, probiotics, kefir, Vit C, coconut oil, B- Complex, Iodine, cilantor, kale, parsley, Boron, fresh fruits and veggies and a host of others can cause herx.
