About This Product

Seeking Health Optimal DIM provides diindolylmethane (DIM) derived from cruciferous vegetable extract, supporting healthy estrogen metabolism and hormonal balance. DIM is a compound naturally found in broccoli, cauliflower, and cabbage that helps the body process and eliminate excess estrogen through favorable metabolic pathways. Each capsule delivers a standardized dose designed to promote the 2-hydroxyestrone pathway (beneficial) over the 16-hydroxyestrone pathway (less favorable). Seeking Health was founded by Dr. Ben Lynch, a naturopathic physician specializing in epigenetics and nutrient metabolism. The product is free from common allergens, artificial additives, and unnecessary fillers.

Why This Is Great for Thyroid Patients

Estrogen dominance — whether from perimenopause, environmental xenoestrogens, or impaired liver detoxification — directly impacts thyroid function. Excess estrogen increases thyroid-binding globulin (TBG), which binds up free thyroid hormones and reduces the active T3 and T4 available to cells. This means you can have "normal" total thyroid levels but insufficient free hormones reaching your tissues. DIM supports healthy estrogen clearance through the liver, helping reduce TBG levels and free up thyroid hormones. For thyroid patients in perimenopause or menopause when estrogen fluctuations are dramatic, DIM helps stabilize the hormonal environment that thyroid function depends on.
