What reduces Glutathione levels in the body?

[Guest guest]

I'm curious as to waht reduces glutathione levels in the body? I

understand that Mercury does, but it doesn't appear I'm at a level

where it should be as depleted as a recent test showed that it was. I

had lab testing done through SpectraCell which indicated that my

glutathione levels were low, along with my antioxident levels. B

Vitamins were showing low as well, though regular blood tests don't

show this.

Thanks,

Mike
