A good detox has three main parts:
Attracting toxins and other nasty stuff
A chelator/binder is used to attract heavy metals—spirulina and minerals like calcium, magnesium, zinc and selenium are examples of common chelators.
Sending those nasties packing by moving them through and out of your body
Once the toxins bind to a chelator, they need to be flushed out. This is where probiotics and foods like fresh fruits, veggies and high fiber supplements make sense. Leafy greens and colorful fruits are high in antioxidants as well, which can be beneficial in supporting your organs.
Supporting your organs etc. while the nasties are moving out
Your liver is the detox organ in your body and supporting liver health is crucial, especially during a detox. There are a number of herbs, foods, and amino acids that people take for liver health, including: beets, milk thistle, dandelion, turmeric, ashwaganda, N-aceital cysteine and many more.
