A combo of blue-green algea and chlorella usually works great.
Bentonite is okay, but small infrequent doses as some of the aluminum may be absorbed. Safest as enema rather than swallowed.
Activated charcoal gets good reviews.
Enemas that use a distilled water solution - metal chelation is the only time that that is a good solution.
Sweating is essential. Many metals can only be released via sweat. So the detox bath, exercise, sauna, should be top priorities. You can do a Vitamin C Flush (500 mg every hour or other hour for 2 days) while sweating, this is very poweful. Don't do the C flush, however, if you take bentonite, as C can enhance the absorption of aluminum.
