My son also take 100mg Chlorophyllin (from sodium copper chlorophyllin) with the 10mg Zinc gluconate that come in one capsule, AND HE SWEARS BY IT. He'll go through psychological withdrawls if he should be running out and the new shipment hasn't arrived yet. I hear that it's good to take zinc with the chlorophyl because because the chlorophyllin has copper, and the zinc somehow helps neutralize it. He takes two in the morning only now that he's on maintenance because he no longer has odor. It is the most expensive supplement he buys, and it costs him $16.49 for 100 capsules, which lasts him almost a couple of months.
