Hi,
Relieved to be in contact for the first time with other people with this enzyme issue MTHFR.
Simple cure for me , I take a dietary supplement made by
Compound Labs in Auckland New Zealand called L-Methionine and I take 1500mg which most take as their dose per day.It can be sourced from food like chicken, tuna, salmon etc but I would never get enough to do the job.I feel normal now and any so-called mental health symptoms vanished as soon as I took it.I also take B6 and zinc due to found deficiencies via blood tests.All of this prescribed by Dr David Codyre, you can find him in Google search.
