Oh I've tried every vitamin and mineral supplement that I think the Nutricentre stock! I'm just very sensitive to them all, even the tiny amounts that Larry Wilson's programme sells. I also bloat up like the michelin man on Vitamin D?! Not sure if its my dodgy hormone profile or the way I absorb them (although tried all the transdermal minerals too) but am just sticking with healthy foods now. To be fair, even they can make me feel bad, particularly if I overdo veg and ultra healthy stuff, so reckon its some kind of phytoestrogen link. I know flax also falls under this so will make sure I don't overdo it!
Fibergel is psyllium husk (plus that key ingredient, aspartame
) which can work well for some.
I think it is true about high progesterone causing constipation, hence it being worse in the second half of cycle for most, but seems to be all month if having strong peri surges.
