Detoxification with NDF Detox/NDF+ Detox typically takes between 6 to 12 months depending on your child’s level of toxicity, biochemistry and his or her current intake. Kids who are inefficient at detoxifying, or have high current exposure to toxins will benefit from a small maintenance intake. NDF Detox/NDF+ Detox can also be used to offset the negative health effects from chlorine as it binds to organochlorides.
