Don't quote me on this, but the heavy metals are being taken care of if you're detoxing everything while using the superfood(which contains the chlorella as mentioned). The chlorella will pull it out of your blood throughout your body, while you're cleansing and strengthening your organs in order to properly dispose of them. From what I've read, mercury will come out in your urine via the kidneys. Nonetheless, you'll poop out everything. Just keep it natural.
Good luck.
