Does Lignan have an estrogenic effect

Ive been taking a lignan supplement that someone from another forum recommended. This is my second bottle, the first time it seem to help with an anxiety, it could have been because of the time i started taking it during my cycle . This time every time i take it i get heart palpitations, whereas before it seem to help. My progesterone is usually very low and i am estrogen dominance. I was wondering if lignan has an estrogen effect. This suppose to be a very powerful antioxidant. This lady thst recommended it swear that it hot rid of her 17 symptoms.

Also, my extremities have been very cold. This has been going on before taking the supplement. Is that a symptom of low estrogen or progesterone?
