I use DIM to counter my estrogen dominance. I also use natural progesterone cream during the two weeks preceding my menstruation as recommended in "What your doctor may not tell you about premenopause". If I don't do this, my menstruations are brutal: I bleed profusely for days, I hurt all over, I get inflammations (that are probably the cause of all the pain), I get depressed.
I never noticed any problems with my Hashimoto's or hypothyroidism on DIM. But then, I'm always on high doses of Iodine
(was on 300 mg I- for a year, now am on 5 grams I-), so that probably counters the effect of any goitrogen I eat.
I also recently found this:
"Vitamin A is known to help with excess estrogen so a simple increase in the amount of natural Vitamin A in the diet can help reduce heavy cyclical bleeding.
It is important to note that beta carotene will not help here – it must be true vitamin A best found in sufficient doses in high vitamin cod liver oil.
According to a case study written about in the book Eat Fat, Lose Fat, 2 TBL of high vitamin cod liver oil per day supplying about 60,000 IU of Vitamin A for 3 days in a row eliminated this debilitating problem for one woman who had been suffering from what she called a “never ending period” for 4 years!
What’s more, a simple daily maintenance dose of 1 TBL of high vitamin cod liver oil (30,000 IU of Vitamin A) was sufficient to keep the problem at bay indefinitely."
In stead of cod liver oil you can also eat liver. Very inexpensive and very healthy. Always take zinc and vitamin E when you're taking vitamin A.
Hope this helps, estrogen dominance is no picknick, I know!
And yes, I want my body to regulate on its own too. The DIM and progesterone cream are not for ever, they are only helpers until my body can take over again. For now, my body needs a little help.
