Seaweed May Lower “Bad” Estrogen Levels
17beta-estradiol is the most potent estrogen in men and women. Excess levels of this hormone relative to other hormones can have an adverse affect on reproductive health, and can be associated with certain types of cancer.
Kelp, bladderwrack and other types of edible seaweeds are most often consumed for their iodine content to support thyroid health. Recently, other uses have been found for edible seaweeds such as the fucoxanthin thermogenic weight-loss ingredient and a new type of vegetarian softgel.
But back in 2004, an interesting but seemingly overlooked study showed that consuming an edible type of seaweed, bladderwrack, was associated with a significant reduction in 17beta-estradiol in pre-menopausal women.

Because bladderwrack supplements are so affordable, safe and well-tolerated, this may be significant new approach to estrogen management for both women and men. Excess estrogen is associated with a range of health issues including breast and reproductive problems and some types of cancer. Those concerned with estrogen balance may wish to consider using bladderwrack along with other nutrients like DIM and Calcium D-glucarate.
