Diindolylmethane (DIM) is a natural compound found in cruciferous vegetables like broccoli, Brussels sprouts, cauliflower, and cabbage. Research suggests DIM may help balance estrogen levels, reduce inflammation, and potentially prevent certain cancers. However, more research is needed to confirm these benefits. Some people use DIM supplements, but it's important to consult a doctor before starting them. Particularly for bone health, DIM might not be beneficial for women after menopause as it could potentially worsen osteoporosis by lowering estrogen levels, which are important for maintaining bone density. Always talk to your doctor about the risks and benefits before adding any new supplement to your diet.
