- DIM

Does DIM Have Any Drug Interactions?
There are some drug classes that DIM may interact with, and these include:
- Drugs that are metabolized by the liver enzyme CYP1A2: DIM may induce this enzyme, increasing the metabolism of certain drugs.
- Diuretics: DIM may reduce sodium levels, and could have additive effects with diuretics that increase sodium loss.
- Estrogen: DIM may have both estrogenic and anti-estrogen effects.
Each of these interactions is presented in detail on individual drug-herbal interaction pages.
Does DIM Have Any Side Effects?
DIM is generally considered safe when taken in appropriate doses, with few reported side effects.
However, some individuals may experience mild gastrointestinal discomfort, headaches, or dizziness when taking DIM.
Additionally, there is some concern that high doses of DIM may interfere with hormone replacement therapy (HRT) by altering estrogen levels in the body (as noted in our drug interaction pages).
Are DIM Supplements Standardized?
DIM supplements are typically standardized to contain a specific amount of the active compound (generally, at least 25% diindolylmethane).
The most common standardization is 100-200 mg per capsule or tablet, although higher doses of up to 600 mg per day have been studied.
It is important to choose a DIM supplement that is standardized to contain a consistent amount of the active compound and that is manufactured by a reputable company.
Many DIM supplements contain Bioperine, a black pepper extract, to improve absorption.
