Now that u mention it, the info on it also stated something about it been a metal detoxer.
My brand is called "SUN A (an exagerated letter A) Chlorella" I bought the gragules but also comes in capsuls I think. Table to content:
Vit A 4559IU
Vit C 5mg
Chlorella pyrenoidosa (pulverized) 3g
Take one pack a day w/ meal...do u know why only one a day and why w/ food?
