Is estrogen in flax seed oil?

Flaxseed oil does not contain estrogen, but it is rich in lignans, which are phytoestrogens. Phytoestrogens are plant compounds that can mimic estrogen in the body, though they are not the same as the hormone itself. The lignans in flaxseed may have various health benefits, including potential effects on hormonal balance. However, the estrogenic activity of these compounds is much weaker than that of human estrogen.
