DIM-Evail™ provides 100 mg of DIM (Diindolylmethane) - a type of compound known as a ‘plant indole.’ Plant indoles, also called glucosinolates, found in cruciferous vegetables provide health benefits to humans. Cruciferous vegetables are known for their cancer protection. Two such indoles provided by cruciferous vegetables are I3C (Indole-3-Carbinol) and DIM (Diindolylmethane). DIM is not naturally present in these plants. It gets released with the help of enzymes upon crushing of the broccoli, cauliflower, cabbage or brussel sprouts or during human digestion (1, 3). Stomach acid, or HCl, can also aid the joining of two indole-3 carbinols to make diindolylmethane. Lack of HCl may hinder one’s ability to make DIM from I3C (2).

DIM is two molecules of I3C combined together. I3C in a capsule is not shelf stable because it is sensitive to light, heat and moisture. I3C may also be irritating to the stomach, and research tells us that it can have negative side effects in doses over 300 mg daily, such as dizziness and unsteady gait, which may be due to nervous system toxicity. One study shows evidence that 90% of orally consumed I3C converts to other compounds, which may be the cause of the side effects. For instance, one compound I3C converts to is ICZ, or indolocarbazole, which causes DNA damage (4). DIM studies show no toxicity when given triple the dose in humans.

How Does DIM-Evail™ Offer Superior Absorption? 

DIM is made up of a crystalline structure that makes it difficult for the body to absorb. To overcome this hurdle, DIM-Evail™ is manufactured using an all-natural process that helps to optimise the absorption of this nutrient by the body. This delivery technology increases the absorption rate and reduces the absorption time for DIM, and as a result, it may allow for superior effects through lower dosages.


Benefits of DIM-Evail™

  • Helps maintain beneficial ratio of 2/16 hydroxyoestrogen
  • Supports healthy balance of testosterone and oestrogen
  • Provides antioxidant properties
  • Has none of the side effects associated with I3C
  • Specifically formulated for maximum absorption and bioavailability

Can DIM be Taken with Medications?

DIM is safe when taken with Tamoxifen, birth control pills and other herbs such as St. John’s Wort that affect cytochrome p450 enzymes. Because of its effects on CYP enzymes, I3C, however, should not be taken with any of these. I3C blocks ovulation, can interfere with birth control pills and may alter the effects of many herbs such as St John’s Wort and could lead to Tamoxifen toxicity if taken simultaneously. Researchers in Minneapolis found that DIM does not affect the metabolism of Tamoxifen. I3C on the other hand, converts Tamoxifen into N-desmethyl-Tamoxifen 3 fold, which itself gets transformed into a genotoxic metabolite (13). Research titled Endocrine Disruption by I3C and Tamoxifen: Blockage of Ovulation may be disturbing to some. This is a quote from the Gao ovulation study: “In the current study, I3C disrupted ovulation already at doses that did not elicit systemictoxicity as indicated by a lack of reduced body weight gain, which was then observed at higher doses.” Gao asserts that “I3C appears to have TCDD-like inhibitory effects on ovulation.” (14) TCDD is a strong dioxin chemical. 

Researchers in Denmark state “Indolo[3,2-b]carbazole (ICZ), which is formed in the acidic environment of the stomach after intake of I3C, has a similar structure to, and shares biological effects with, the well-known tumor promoter 2,3,7, 8-tetrachlorodibenzo-p-dioxin (TCDD).” This is the conclusion of their study: “Further studies are needed in order to clarify the anticarcinogenic/carcinogenic effects of I3C and ICZ before high doses of I3C may be recommended as a dietary supplement.” They feel that ICZ’s tumor promoting activity is due to its activation of the Ah receptor and stimulation of certain cytochrome p450 enzymes mainly Cyp1a1, Cyp1a2 and Cyp1b1 (15).

DIM’s proven safety means that DIM can be used by women wishing to get pregnant but should be discontinued during pregnancy and lactation. There are no known contraindications for DIM supplementation.
