In another forum, someone (Phil, I think) who often says "DIM lowers E2" posted a link to
http://www.dimfaq.com/site/diagram.htm.
The way I read it, DIM does not lower E2 (as if to lower it being aromatized from T), but rather it influences or is involved with the metabolites (the products of what the body does with) E2. In other words, as DavidZ said above: "helps the liver digest/metabolize Estradiol into more benign/healthy estrogens".... The way I see it, E2, regardless of a given quantity at a given moment in time, will eventually be metabolized by our livers into something else. DIM helps or influences the liver's function in this, but does no lower the given quantity at a given moment to begin with. WF
Yes, if you read the material that Dr. Zeligs sends (upon request) concerning his "bioavailable DIM" product, he makes it clear at multiple different points in that literature that DIM does NOT lower E2 levels per se, but that DIM aids the metabolization of E2 into more favorable metabolites.
I have thoroughly examined the "blood test chart" provided by DZ:

08/11/05 620 45 13.8
09/28/05 661 30 22.0
And I have noted a number of specifics.
First of all the chart only specifies Total T (no Free T or Bioavailable T), E2 (no Total Es) and a Total T/E2 ratio. It seems to me that a Free T / E2 ratio would have been more enlightening.
Secondly, I noted that there's no information given as to the specifics of the TRT regimen. This was an HcG-Only protocol over this time period (i.e., no administered external T), but nothing is said as to amounts and/or frequency (500 IU once a week? 350 IU twice a week? 100 IU daily?). Also there's NO mention of what reference ranges were employed by his testing lab(s) over this six year time period. Obviously the protocol of the HcG - as to total weekly amount, amount per dose, and number of doses per week - all can play into accounting for E2 levels, yet the reader has none of that information available.
Finally, I see no real established pattern that could be explained by means of strictly DIM usage (especially in amounts stated... 1/2 tablet, etc., etc. - Communications with Dr. Zeligs have him indicating that would be ridiculous, that he feels males need 200 - 400 mg of DIM for any type of effective estrogen control - not reduction, but control - via metabolization).
Anyway, from March of 2000 to November of 2000 (with no transdermal chrysin or DIM ingestion) one sees the following:
03/03/00 1303 101 12.9
03/21/00 595 69 8.6
04/29/00 753 72 10.5
06/05/00 463 38 12.2
08/09/00 795 81 9.8
09/16/00 981 91 10.8
10/09/00 494 50 9.9
11/11/00 1144 76 15.1
12/04/00 471 54 8.7
While there's a lot of bouncing around going on, the main characteristic is that when Total T was high then E2 tended to be high - and when Total T was lower then E2 was lower. Not completely consistent, but then again this is the start up of this protocol. And - again - no detailed information given as to the HcG protocol being employed over this time period. High levels of HcG employed too frequently could account for much of the early elevated E2 levels.
I then looked at the time frame from when the DIM was started:
08/02/01 829 40 20.7
09/22/01 708 39 18.2
12/01/01 782 55 14.2
02/23/02 895 40 22.4
05/18/02 696 55 12.7
07/27/02 889 30 29.6
08/24/02 1202 71 16.9
10/05/02 534 38 14.1
12/07/02 1115 80 13.9
03/08/03 791 51 15.5
04/19/03 762 42 18.1
05/17/03 713 38 18.8
06/28/03 460 30 15.3
07/26/03 703 49 14.3
12/27/03 851 35 24.3
03/06/04 776 40 19.4
05/22/04 823 40 20.6
07/24/04 690 39 17.7
09/29/04 812 46 17.7
02/26/05 605 21 28.8
03/26/05 607 21 28.9
04/26/05 682 39 17.5
05/31/05 639 36 17.8
08/11/05 620 45 13.8
09/28/05 661 30 22.0
One sees even more clearly that relationship. It seems to demonstrate even more emphatically that the E2 levels have paralleled the levels of Total T. The last eight test results showed Total T in the 600s in seven of those tests. The one exception was just over 800. The E2 level was a 46 for that 812, yet there was an E2 of 45 when the Total T was down to 620??? But overall, once again, it was obvious that the lower Total T levels resulted in lower E2 levels.
Additionally, assuming a reference range of 260 - 1000, I personally would not consider Total T levels in the 600s to be "optimum levels". The upper quarter of that range would be roughly 800 - 1000. (I used that reference range only due to the number of instances that Total T came back well over 1000).
Anyway, my examination of this "chart" only seems to verify that E2 levels primarily paralleled Total T levels... once those Total T levels were stabilized with an apparently fiemly set HcG protocol... prior to that stabilization it seems like there was a lot of experimentation and tweaking going on with the way that numbers were up and down so drastically.
Personally I believe that DIM (used in conjunction with TMG) has some definite health benefits but that it does not fall into the same definitions as AIs or Anti Es for E2 / estrogen control purposes. I also believe that Dr Zeligs info is more likely correct, that doses in amounts of 200 - 400 mg are therapeutic levels for those health purposes versus half tablet theories, but then that's just IMHO...
