i used to have psoriasis. still have the underlying tendency, but it's finally clear for the first time since what.. the 80s? if i back off on the regimen it reappears, but i don't know which are the critical parts of the mix. i don't see any fumarates in my multi, and my iron is ferrous gluconate, not fumarate form.
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
