The Claim
Many people believe that DIM acts as a natural estrogen blocker, reducing estrogen levels in the body and therefore preventing estrogen-related conditions such as breast cancer.
Origin
This myth likely stems from early studies and marketing claims suggesting that DIM can modulate estrogen metabolism, influencing its effects.
What Science Says
Research indicates that DIM does influence estrogen metabolism, but it does not act as a direct estrogen blocker. Some studies, including randomized controlled trials (RCTs), show that DIM promotes the conversion of potent estrogens to less potent forms, which might influence estrogenic activity. However, these effects are not the same as blocking estrogen production or activity.
Verdict
Misleading
