Hi, I'm new here. I just used the sulfate testing strips for the first time. I followed package directions. The strip indicated that my sulfate levels were at or below 200. How can this be? I have been avoiding eggs, brassica vegs (cabbage etc.), garlic, onions asparagus for about a week. Would my CBS +/- and BHMT +/- and MTHFR +/- not be expressing as much as I thought? I can't afford a lot of lab tests. I will have to figure out how to heal based on what my body symptoms indicate---and affordable things like the sulfate test strips.
