What Real Food Vitamins say about DIM-EVAIL™:

DIM is effectively used for hormone imbalances in women, especially those who are trying to lose weight. Research suggests that DIM helps to improve weight loss resistance that occurs due to hormonal imbalance, in addition to protecting against other hormonally related conditions such as PMS, PCOS, endometriosis and fibroid tumors. A general recommendation is one softgel per day.

Manufacturer's Description:

Due to its crystalline structure, absorption of DIM is minimal when given orally (similar to CoQ10). DIM absorption can be greatly enhanced by emulsifying it with lecithin oil, including with it compounds that hold it in solution such as beeswax, and finally by adding fat-soluble nutrients that aid absorption through the gut wall. DIM-Avail™, which gets its name from its high bioavailability, is a unique combination of such ingredients.

Research tells us that a low level of the 2-hydroxyestrone, and a high level of 16 alpha-hydroxyestrone is not desired. DIM works by helping to increase 2-hydroxyestrone and therefore improves the 2/16 hydroxyestrone ratio.*

What actions does DIM have on the body that makes it beneficial to our health?

Research shows that a low level of 2-hydroxyestrone, and a high level of 16 alpha-hydroxyestrone is associated with an enhanced risk of breast cancer. DIM increases 2-hydroxyestrone and therefore improves the 2/16 hydroxyestrone ratio, making it very protective for women and men at high risk for this condition. Research by Bradlow shows that DIM also reduces the availability of 4-androstenedione for aromatization to estrone, a more dangerous form of estrogen. He concludes that DIM is more potent than I3C in protecting against breast cancer due to decreased formation of 16 alpha-hydroxyestrone from estrone.

DIM supplementation improves the estrogen ratio in a favorable direction that protects both men and women without the negative effect of raising 4 hydroxyestrogen, as seen with I3C. DIM does not block ovulation the way I3C does, and unlike I3C it can be used safely along with Tamoxifen.

DIM should be considered as first-line therapy for hormone imbalances that can lead to negative conditions such as PMS, PCOS, endometriosis, fibroid tumors, menopausal symptoms, weight problems, and the list goes on.

Recent research suggests that DIM may improve weight loss resistance that occurs due to hormonal imbalance.

Is DIM hard to absorb?

DIM-EVAIL™ uses the same proven technology as Designs for Health’s Q-Avail™; research in human subjects shows it to have far superior bioavailability and peak absorption rates in comparison to powdered CoQ10 and sublingual forms.

General Recommendation: As a dietary supplement, take one softgel, or as directed by your health care practitioner.
