Hi forum. So, I recently have been tested and diganosed for double heterozygous MTHFR, but now, I realize that every time I eat a sulfur veggie it sits like a brick and I get an adverse reaction to. I also have some symptoms associated with depleted BH4. Do I likely have a CBS mutation or a "CBS upregulation", both or neither?? So, I plan to eat a low sulfur diet and to do charcoal/ magnesium flushes. My other question is, when do I reintroduce sulfur? And will I ever be able to eat a lot of sulfur veggies again?? I'd like to be able to follow the Wahls' Protocol ideally.
