8 Health Benefits Of Flaxseed That Prove It’s A Superfood


Arguably flaxseed’s most unique health benefit is its ability to affect your menstrual cycle. According to a study in the National Center for Biotechnology Information, flaxseed contains high levels of lignans, which are phytoestrogens — plant forms of estrogen — that contribute very small amounts of estrogen in the body.

“Flaxseed has been found to actually improve your progesterone to estrogen ratio in the luteal phase, which is the PMS phase of your cycle,” Samuel says. Basically, this means eating flaxseed can potentially help regulate your PMS symptoms.
