I have the Sun chlorella. I have been taking it because it is a fabulous nutrient and detoxifiyer. I am not taking enough of it for chelation. I take 3 or less grams a day and feel great from it. When my mouth is entirely clear of mercury, I may chelate some day. I got rid of my fillings, but I need to find out about my crowns and stuff. There must be some still in there! Have to ask my dentist this year at my visits. In the mean time, chlorella helps detoxify and clean your blood. It soaks up toxins, and I'm thinking candida toxins. I mix it with wheat grass powder and make a super green drink. What I've researched is that you can take 10-15 grams to fight disease, 5-7 grams daily, so I'm taking just a very small dose. The sun comes in packets of 3 grams. To chelate, I think you take like 25-30 grams a day. But don't quote me on that.
