Progestogen / hormone replacement
Is Progesterone vegetarian or vegan-friendly?
Vegetarian and vegan patients sometimes ask whether their medication contains animal-derived ingredients. The active substance Progesterone in Progesterone is almost always synthetically produced; the question typically concerns excipients in the tablet or capsule shell at 100mg, 200mg.
Animal-derived excipients in Progesterone
Common animal-derived excipients in pharmaceuticals include gelatin (in capsule shells, derived from porcine or bovine sources), lactose (dairy-derived), and certain magnesium stearate sources. The prescribing information and patient leaflet for Progesterone list excipients; whether they are animal-derived is sometimes specified, sometimes left ambiguous. Progesterone binds to progesterone receptors and modulates gene expression in reproductive and other tissues.
Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Progesterone excipients should ask the pharmacist or manufacturer directly. Many medications have authorised generic versions with different excipient profiles — switching to a generic of Progesterone with vegetable-derived excipients is sometimes possible at 100mg, 200mg. For strict requirements (e.g. religious or strong ethical), specialist pharmacy consultation gives definitive answers.
