NutraDIM™ DIM (Diindolylmethane)


NutraDIM™ is a high quality DIM (or diindolylmethane) supplement. DIM is a natural component of I3C (indole-3-carbinol), found in healthy vegetables like broccoli, kale and cauliflower. These delicious vegetables are widely regarded as superfoods for this very reason.

Scientifically shown to have powerful effects on estrogen metabolism, this supplement can support: 

  • A healthy and balanced estrogen level (in both men and women)
  • Menopause and estrogen dominance (in women)
  • Estrogen blocking for bodybuilders (in men) - increasing the ratio of testosterone to estrogen
  • Enhanced energy and libido
  • Weight loss, strong heads of hair and clear skin (clearing noncystic hormonal acne)
  • Overall healthy estrogen metabolism 

If you’re trying to minimize the estrogen flowing through your body, (and reap the countless health benefits) - DIM should be a key part of your daily supplement regimen.

Promotes Healthy Estrogen Metabolism & Normal Hormone Levels

With its potent effects on your estrogen metabolism, DIM is a powerful way to balance the hormone estrogen in your body (by preventing either drastic increases or decreases).

DIM is a natural substance generated when the body breaks down I3C, commonly found in healthy vegetables like broccoli and kale.

It can inhibit an enzyme converting testosterone to estrogen, and it can even convert more potent forms of estrogen into LESS potent forms. In very large doses, it can work the other way around, and increase estrogen synthesis.

This means that you can use DIM to balance the estrogen in your body to the healthy level you want. 

Use NutraDIM™ to maintain balanced estrogen levels in your body, and healthy estrogen metabolism.

A Look at Diindolylmethane – DIM, with Black Pepper Extract

  • Supports balance of the sex hormones estrogen and testosterone
  • Likely to enhance libido
  • May help to support a healthier weight
  • Supports healthy menopause in women
  • May support efficient blocking of estrogen in men looking to build muscle mass

The body produces Diindolylmethane (DIM) during the digestive breakdown of the phytochemical indole-3-carbinol (I3C). Thus I3C acts a precursor of 3,3′-Diindolylmethane.

This glucosinolate phytochemical is naturally found in members of the Brassica plant family, such as broccoli, cabbage, cauliflower, and Kale. One of the main reasons why these green cruciferous vegetables are considered to be a healthy food is because of their natural high content of I3C / DIM [1]. 

Due to its potential role in the support of healthy cell growth a lot of current research focuses on the role that DIM plays as a histone deacetylase inhibitor. DIM is also strongly associated with supporting the control of estrogen at healthy levels, and may be involved in the support of genetic repair mechanisms.

As a source of piperine, black pepper is able to play a role in the inhibition of detoxifying enzymes involved in glucuronidation in the liver. It may help to support the uptake of molecules in the body, and so help to maintain the bioavailability of supplements and drugs [2]. Other active components of black pepper spice extract include guineensine, pellitorine, piperonal, pipnoohine, and trichostachine [3].

Sex Hormone Homeostasis

DIM is thought to play a role in balancing the homeostasis of the sex hormones estrogen and testosterone. As estrogen is broken down in the body it is converted into metabolites. Depending on their type these may be either beneficial or harmful for human health. DIM may help to support the levels of healthy 2-hydroxyestrone, and to lower the levels of unhealthier estrogenic metabolites. DIM is also thought to play a role in preventing any major deviations from the norm, and thus prevent spiking of hormone levels.

DIM is able to activate estrogen receptor ERα and ERβ subsets [4]. The mechanisms mediated by these receptors are thought to occur indirectly.

The activation of ERα is thought to act in both a cell dependent and dosage dependent manner. DIM has been demonstrated to have an effect on cell proliferation through stimulating cell growth via the estrogen receptor α signaling pathway at low dosage levels [5]. This growth acts independently of 17β-estradiol and also involves the protein kinase A signaling pathway.

DIM is able to stimulate the binding of regulatory elements by ERβ and to activate ER target genes through the recruitment of a steroid receptor coactivator [4]. 

DIM is thought to have a role in the modification of estrogen steroids via the 2-hydroxylation process. This role is thought to be secondary to its role in inducing AhR responsive genes [6]. The 2-hydroxylation process involves alteration of the 2-hydroxyestrone to 16α-hydroxyestrone ratios [7], and hence may lead to a lowering of the overall estrogenic profile. This has an overall effect of changing estrogen into a less potent form, and thus lowering the biological impact of the hormone in the body.

When taken orally DIM may help to support healthier levels of urinary 2-hydroxyestrone concentrations in women [8]. 2-hydroxyestrone has been speculated to be a beneficial estrogen with regards to women’s health [8]. 

DIM may inhibit the activation of the adrenal enzyme aromatase. This enzyme is involved in testosterone to estrogen conversion [9]. It has been demonstrated to affect the levels of dihydrotestosterone (DHT) in the prostate independently of the androgen receptor. This inhibition of conversion of testosterone into estrogen may affect the ratios of these two sex hormones and thus may prove of interest to people in the bodybuilding community. 

Weight Control 

In obese mice undergoing a high fat diet, the injection of 5 mg per KG of I3C (the precursor of DIM) was observed to affect numerous factors associated with obesity. I3C treatment supported healthy glucose tolerance, and healthier insulin and leptin concentrations in the mice. Overall, there was a decrease in body weight and in the accumulation of fat in the indole-3-carbinol treated mice group [10].

    What foods are high in DIM?

    If you want to include DIM naturally in your diet then you may wish to eat more of the following Indole-3-Carbinol rich cruciferous vegetables: Bok Choy; Broccoli; Brussels sprouts; Cabbage (Red, Savoy) Cauliflower; Collard greens, Horseradish, Kale; Kohlrabi; Mustard; Rutabaga, Turnip, and watercress. The vegetables with the highest natural IC3 content are cress (392 mg / 100 g), greens (282 mg/100 gram), and turnips (92 milligrams per hundred grams). You will need to eat a lot of raw vegetables everyday to get the same amount of DIM that is contained in our NutraDIMTM product.

    Does cooking affect glucosinolates levels?

    Yes, most people eat cooked vegetables. Heating has a negative effect on the oral bioavailability of glucosinolates such as IC3. This is largely because the enzyme Myrosinase (which is involved in glucobrassicin metabolism) is destroyed / deactivated with the increase in high temperatures and so cannot convert DIM at maximal rates. If you plan to get DIM from you diet it is best to eat your vegetables like I do, I eat my vegetables raw. 

    Do people stack DIM with other compounds?

    People interested in increasing their athletic performance may often take DIM alongside testosterone boosters.
