Overview

Diindolylmethane (DIM) is a compound derived from the digestion of indole-3-carbinol, which is found in cruciferous vegetables such as broccoli, Brussels sprouts, cabbage, and cauliflower. DIM is believed to help balance hormone levels, particularly estrogen, in the body. It is thought to work by promoting the conversion of estrogen into its beneficial metabolites, rather than its more harmful ones. This has led to interest in DIM as a supplement for a variety of hormone-related conditions, including PMS, menopause symptoms, and certain types of cancer. DIM is also used to support prostate health in men. Research on DIM is ongoing, but some studies have shown promising results for its ability to support healthy estrogen metabolism and reduce the risk of hormone-related health issues.

Key Benefits

Supports Healthy Estrogen Metabolism

DIM helps promote the production of beneficial estrogen metabolites, which may reduce the risk of hormone-related health problems.

Alleviates PMS and Menopause Symptoms

By helping to balance hormone levels, DIM may reduce symptoms such as mood swings, hot flashes, and bloating.

Promotes Prostate Health

DIM may help support prostate health by promoting healthy estrogen metabolism in men.

Dosage & How to Take

DIM is typically taken in doses of 100-200 mg per day. It is best to start with a lower dose and gradually increase as needed.
