Is Progesterone Vegetarian?
CautionSometimes. 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).
Progesterone and the Vegetarian Diet
Progesterone is a naturally occurring steroid hormone involved in the menstrual cycle, pregnancy, and embryogenesis in humans and other species. While it is primarily used in medications, supplements, and cosmetics, it is not typically an ingredient in food products. Progesterone can be synthesized from animal sources such as yams or soybeans, which are then chemically converted to progesterone in laboratories.
