Is Oestrogen Vegetarian?

Caution

Sometimes. This ingredient could be derived from animal sources but is not usually seen in food (more typically seen in medications, supplements, cosmetics and/or cleaning supplies).

Oestrogen and the Vegetarian Diet

Oestrogen is a group of steroid hormones that play a crucial role in the development and regulation of the female reproductive system and secondary sexual characteristics. While it is naturally produced in the body, oestrogen is also used in various medications, including hormone replacement therapies and contraceptives. It appears less frequently in food products but may be present in certain supplements and cosmetics. Oestrogen can be derived from animal sources, synthetic processes, or phytoestrogens, which are plant-based compounds with estrogenic activity.
