Progesterone for vegans — animal-origin ingredient questions
For people on a vegan or strict vegetarian diet, the question of whether Progesterone (Progesterone) contains animal-derived ingredients is a real practical concern. Progesterone is used for Progesterone is approved for endometrial protection in postmenopausal women receiving estrogen, secondary amenorrhoea, luteal-phase support in IVF/ART, and prevention of preterm birth in women with sh…; like most prescription medications it can contain excipients or capsule materials whose origin is not always obvious from the outer packaging. Below is what the available labelling typically tells us about animal-origin components in Progesterone and what alternatives may exist around the 100mg, 200mg dosing strengths.
Capsule shells and tablet coatings in Progesterone
The most common animal-derived component in any oral medication is gelatin, used in the shell of soft and hard capsules and extracted from bovine or porcine tissue. According to the Progesterone prescribing information, the available dosage forms are capsule — gelatin capsules should be assumed non-vegan unless the manufacturer specifies an HPMC (hypromellose, plant-derived) shell. Tablet film coatings are usually plant-based; enteric coatings on a small subset of products can use shellac, an insect-derived resin. Pharmacy staff can confirm which formulation of Progesterone at the 100mg, 200mg strengths uses gelatin and which does not.
Common excipients of animal origin
Beyond the capsule, several excipients have potential animal-origin variants. Lactose monohydrate, present in many tablets, is dairy-derived. Magnesium stearate and stearic acid can be sourced from animal or vegetable fat — modern pharmaceutical manufacturing typically uses vegetable, but the prescribing information rarely states the source. Cochineal (E120) is a possible colourant of insect origin. The full excipient list for Progesterone (Progesterone) is published with the Progestogen / hormone replacement class label; people following strict diets are encouraged to review it for each new prescription, as generic manufacturers can vary in their formulations and excipient choices.

For Progesterone (Progesterone) specifically, the availability of a vegan-suitable form depends on the local market.
