The very hormones we need to stay young can cause adverse effects as we age. Consumption of cruciferous vegetables, such as broccoli, cauliflower and Brussels sprouts, can favorably alter one's hormone profile.

Scientists have identified specific extracts from cruciferous vegetables that modulate hormones in a way to help maintain healthy cell division. For instance, animal studies have shown that the cruciferous vegetable extract indole-3-carbinol (I3C) modulates estrogen hormones by favorably changing the ratio of protective 2-hydroxyestrone versus the damaging 16-hydroxyestrone.¹ Indole-3-carbinol also induces phase I and II detoxifying enzymes that can help neutralize estrogen metabolites and xenobiotic estrogen-like environmental chemicals.² Human studies support the beneficial role of I3C in positively altering estrogen metabolism.³ Di-indoyl-methane (DIM), a phytonutrient found in cruciferous vegetables, has been shown in animal studies to help maintain normal levels of a potentially damaging estrogen called 4-hydroxyestrone.⁴  I3C and DIM have been shown to affect the proliferation of cells containing DNA damage and induce DNA repair proteins. The glucosinolates are major constituents of cruciferous vegetables that have been shown to promote normal apoptosis (programmed cell death of bad cells) and induce the expression of the beneficial p53 gene via an estrogen-independent action.

Indole-3-carbinol shows great potential in preventing cancer, especially hormone-related cancers such as breast and prostate.  I3C is  works both as an antioxidant and as a cancer fighter. Research on I3C dates to the 1960s when it was investigated for its actions against chemical carcinogens. Since that time, researchers have been able to show that I3C has powerful and diverse ways of stopping cancer. While the break-down products of I3C may act unpredictably by themselves, when taken as I3C they are beneficial for preventing, and possibly treating, hormone-related cancers. The data is so compelling, it has provoked normally reserved researchers into such praise as, ³I3C has tremendous potential in the treatment and prevention of cancer, particularly estrogen-enhanced cancer. (Meng Q, et al. 2000. J Nutr 130:2927-31). Although that comment was directed towards I3C¹s estrogen-blocking potential, I3C has equally important actions against all types of cancer.

A summary of studies shows that this vegetable extract:

• Increases the conversion of estradiol to “weaker” (2OHE) estrogen, which has been shown to reduce breast cancer incidence
   
• Works in estrogen receptor negative breast cancer cells.
   
• Stops human cancer cells from growing (54-61%) and provokes the cells to self-destruct (apoptosis).
   
• Inhibits MCF7 human breast cancer cells better than tamoxifen under laboratory conditions.
   
• Protects against the environmental toxin, dioxin.
   
• Restores p21 tumor suppressor gene.
   
• Provides antioxidant protection.

The glucosinolates are major constituents of cruciferous vegetables that have been shown to promote normal apoptosis and induce the expression of the beneficial p53 gene via an estrogen-independent action.⁵

Watercress contains isothiocyanates, but in a broader spectrum than does broccoli. The primary isothiocyanate precursor (PEiTC) in watercress functions via four specific mechanisms to maintain healthy cell division.⁶ Extracts from rosemary enhance liver metabolism of estradiol and estrone,⁷ inhibits the formation of DNA adducts,8 and have been shown to impede estrogen-induced growth promotion in certain tissues.⁷

Based on a growing body of evidence that cruciferous vegetable extracts (in addition to I3C) provide bountiful health benefits, Life Extension has reformulated its I3C supplements to more closely resemble what one would obtain from a vegetable-rich diet.

Life Extension has combined its cruciferous vegetable complex with a standardized resveratrol extract based on indications from published scientific literature that resveratrol may also be an effective plant extract for maintaining optimal health. This organic whole-grape extract contains a spectrum of polyphenols naturally found in red wine, such as proanthocyanidins, anthocyanins, and flavonoids.
