WARNING: Chelation doesn't work alone!
Only use following products in accordance with Chlorellaman's 3-step heavy metal detox system
Chlorella
Yaeyama chlorella is an algae. Used in Japan after the H bomb to help people exposed to radiations. An excellent Mercury Detoxifiant.
Cilantro
Also called coriander. An herb, you can find fresh most days at any supermarket.

EDTA
A molecule. Available in caps or injections. 2 * 650mg pill before going to bed.
DMSA
DMSA, very effective, pricier, I recommend it if you have different kind of heavy metal poisoning. For example I had about 7 heavy metal poisoning and 4 in high quantities. So DMSA is a great solution if you can handle it. Some people get fatigued on it even with dietary supplements and extra vitamins taken after it.
If you have only 1 or 2 heavy metals, you can go the penny saver way with Chlorella (Hg Detox), Cilantro (Hg Detox) and EDTA (Pb Detoxx). Otherwise heavy metal detox is an investment. It costs time, care, and a lot of strength and courage. Good luck with your detox.
Magnesium
An essential metallic element. Non toxic, non heavy. Bonds to heavy metal.

Antioxydants
In grand quanities in white teas. Helps chelate aluminum
Enzymes
Help the dumping of heavy metal out of the human system.
Drainages
Homeopatic bottles. Clean out individual organs.
