Estrogen dominance is considered one of the factors of breast lumps.
The phytoestrogens in pine pollen may help moderate estrogen levels by binding to estrogen receptors, potentially reducing the intensity of estrogen's effects in cases of estrogen dominance.
While pine pollen contains phytoestrogens, it also contains compounds that may help support the production of other hormones, like progesterone. By balancing estrogen and progesterone, pine pollen could theoretically help correct the hormonal imbalance that underlies estrogen dominance.
