@aleksfidurski: Vitamin A does more than support vision. Retinol plays a major role in hormone regulation, cellular differentiation, and thyroid function. Research suggests that adequate vitamin A can help oppose excessive estrogenic effects and support a healthier hormonal balance. This is one reason vitamin A has been studied in conditions associated with estrogen dominance and impaired metabolic function. In the bioenergetic view, estrogen rises during stress and low metabolic states, while nutrients like vitamin A help restore normal cellular function and hormone balance. The bigger lesson: hormones don’t exist in isolation. They depend on nutrition, thyroid function, liver health, and energy production.
