*** I ended up with High Blood Pressure taking TTFD. I no longer take TTFD. Based on my experience, I would not recommend TTFD. ***
Excellent write up on Thiamine Tetrahydrofurfuryl Disulfide (TTFD) but I am unsure if it is a Methyl Donor or requires a Methyl Donor. eonutrition.co.uk/post/is-t...
The TFD component of TTFD clearly requires a Methyl donor. "....by using up SAM-e, TTFD could also theoretically increase the requirement for some of the other nutrients involved in the methylation cycle. These might include the B complex vitamins, particularly folate, riboflavin and vitamin B12." hormonesmatter.com/paradoxi...
So if you feel worst take something to increase methylation.
