What is DIM?
Diindolylmethane (DIM) is a substance created by the body when the compound indole-3-carbino is consumed. Found in many cruciferous vegetables, DIM is a natural substance believed to have many health benefits.
DIM has gained in popularity because it shows promise as a treatment for various ailments. For example, it is believed to help alleviate hormonal imbalances in women, premenstrual syndrome (PMS), and some cancers. In addition, men may find it useful because it can help with enlarged prostate and lowering prostate-specific antigen (PSA) levels. Other potential uses include treatments for acne, obesity and weight loss.
Foods Containing DIM
- Brussels sprouts
- Bok Choy
Benefits of DIM
DIM has been used to treat a variety of health issues. Here are some of the most popular uses of DIM:
Preliminary studies indicate DIM might help prevent the growth of cancer cells. A study on women taking tamoxifen, a drug used to treat breast cancer and DIM supplements indicate daily consumption of DIM “ promoted favorable changes in estrogen metabolism and circulating levels of sex hormone-binding globulin.” 
Regulating Weight Loss
Studies indicate DIM might be an effective tool for weight loss: The administration of 50 mg of DIM “significantly suppressed HFD-induced obesity, associated with a decrease in adipose tissue.” Researchers concluded cruciferous vegetables that can produce DIM “have the potential to prevent or treat chronic obesity.”
Menopause is the natural aging process in women where ovaries stop producing reproductive hormones and menstrual periods permanently stop. Estrogen levels tend to fall during menopause and could break down into “good” or “bad” metabolites. DIM can help produce good metabolites, ease menopausal symptoms, reduce the risk of breast tenderness, decrease cervical problems, and reduce the risk of some cancers.
Prostate Cancer Prevention
Prostate cancer is cancer of the prostate gland and one of the most common cancers in American men. Epidemiological and dietary studies have revealed an association between high dietary intake of cruciferous vegetables and decreased prostate cancer risk.
Elevated levels of androgens (hormones like testosterone) are associated with acne. An imbalance of these hormones could lead to increased sebum production, which is the oily secretion of the sebaceous glands. These secretions lead to clogged pores and cause breakouts. DIM could help keep these hormones balanced, potentially decreasing the risk of acne.
Side Effects of DIM
Studies on DIM have not found any long-term side effects to using DIM supplements. DIM is considered safe for most people when taken by mouth for medicinal purposes. Minor side effects from DIM supplements could include darkening urine, increased bowel movements, nausea, and headaches.
How to Take DIM
Because there are few long-term studies available, consulting with a doctor before taking DIM supplements is advised. Dosage requirements can depend on age, overall health, and other factors. In addition, DIM supplements should be taken with food. It’s also important to stay hydrated when taking DIM supplements.
