WHY CHOOSE US

TO SUPPORT ESTROGEN METABOLISM?

Most other DIM supplements do not contain a clinically-proven daily serving of 300 mg of DIM (Diindolylmethane) to help reduce excess estrogen levels and promote hormonal balance. Most do not include Brassi-Sci, a trademarked metabolic complex made up of Broccoli sprout powder and Mustard seed powder which boosts the effects of DIM while providing powerful antioxidant effects. Many DIM products do not include Calcium-D-Glucarate which inhibits the reabsorption of estrogen via the gut and contributes to the expulsion of undesirable toxins. And most don’t contain BioPerine® for added bioavailability, more efficient nutrient absorption, and quicker results. The truth is that most DIM supplements do not live up to their claims. Most do not have the potency needed. And most contain ingredients such as unnecessary proprietary blends, additives, preservatives, or binders.

Due to extensive research and our firm understanding of what makes an effective DIM supplement, we have created a product that is uniquely formulated to decrease excessive estrogen levels and support hormone metabolism.

Each ingredient was carefully selected, based on years of research and clinical studies. Over 20 years of safety and efficacy research has been documented on what ingredients should be included in a quality DIM supplement to get the very best results possible with absolutely no side effects.

HOW DOES

APPROVED SCIENCE® DIM WORK?

White bottle labeled DIM + BioPerine, 60 capsules.Approved Science® DIM uses extensively researched ingredients to create a bioavailable DIM supplement that helps maintain healthy estrogen metabolism. This process includes eliminating excess estrogen by raising DIM levels in the body. This unique formula contains a clinically-researched daily serving of 300 mg of DIM as well as Calcium-D-Glucarate which helps inhibit the recycling of estrogen and eliminates harmful environmental toxins from the body. Approved Science® DIM also includes Brassi-Sci, a trademarked metabolic complex made up of Broccoli sprout powder and Mustard seed powder. This synergistic combination promotes better absorption of DIM in the body while supporting estrogen detoxification and boosting antioxidant activity.

To top it all off, Approved Science® DIM also includes BioPerine®, the patented extract from black pepper that significantly enhances the bioavailability of active ingredients for more effective results. Supplementing with DIM helps maintain balanced estrogen levels and works to prevent an irregular proliferation of cells in the breast and uterine tissues.

This top quality DIM supplement provides the 4 essential elements of success: Balance, Maintain, Protect, and Reduce - providing you with the ultimate formula to eliminate excess estrogen and support hormone metabolism.

In terms of quality and purity of ingredients, there is nothing else on the market that comes close to Approved Science® DIM.

  • Balanced scales representing equilibrium.

    STEP #1 BALANCE

    Approved Science® DIM is formulated to increase the amount of DIM in your system, which directly affects estrogen levels. DIM helps eliminate excess estrogen, thus conditioning a stable hormonal environment. DIM is created by a process that occurs when we eat certain foods such as cruciferous vegetables. Taking a DIM supplement eliminates the additional process by offering it in a concentrated amount.

    STEP #2 MAINTAIN

    Imbalanced estrogen can play with your mood, your weight, and the health of your muscle tissue. Excessive estrogen or hormone imbalance is common during menopause or as the result of birth control pills. Calcium-D-Glucarate helps to maintain a healthy estrogen metabolism and fight estrogen dominance by restricting estrogen reabsorption.

  • Atomic structure with orbiting electrons.

    STEP #3 PROTECT

    Approved Science® DIM has a trademarked blend, Brassi-Sci, which combines Broccoli sprout powder and Mustard seed powder. Broccoli contains an enzyme that is processed into a powerful antioxidant. However, seeing as this enzyme is not absorbed easily into the body, Approved Science® DIM includes Mustard powder. Mustard seeds boost the effects of the Broccoli powder, enhancing the body’s antioxidant and anti-inflammatory mechanisms.

    STEP #4 REDUCE

    Estrogen dominance can lead to undesirable symptoms that may manifest in physical ways such as painful breasts, damaged muscle tissue, or weight gain. It may also cause mood swings, sleep issues, and fatigue. DIM helps reduce these symptoms that are common with estrogen imbalance.
