Some US medics have shown recently that using vitamins A K And D have boosted T3 conversion by up to 61%.
This work interests me as I have started a new version of a high quality vitamin pill with much higher doses of D3 and includes K.
It also includes chelate selenium and zinc in sensible levels.
Up to Christmas I added zinc and selenium but stopped and tried an inferior multivit.
I am really shocked to realise that within a few days of taking these my pulse has gone back to where it was before Christmas eg 60 not 45 and weight that was all lost last year and since came back on is shedding off again.
So I suspect for those failing to lose weight and struggling with conversion issues these are going to be very helpful.
I reluctantly accept that these supplements are for life ....
