Estrogen dominance is a term coined by John R. Lee, M.D., the great pioneer in natural hormones. It refers to an excess of estrogen relative to not enough progesterone. In other words, you can have normal or low estrogen levels, but if you have low progesterone you will have estrogen dominance. Estrogen and progesterone bring hormone harmony when they're in balance with each other.
