Editorial summary
This summary is editorial and is general information, not a religious ruling. The status above is unchanged.
What it is
Vitamin D3, or cholecalciferol, is the form of vitamin D made in the skin and added to fortified milk, cereals, supplements and multivitamins. The National Institutes of Health Office of Dietary Supplements explains that D3 is typically produced by irradiating 7-dehydrocholesterol from lanolin, the grease in sheep's wool, and that an animal-free D3 made from lichen is also available.
Why the status is doubtful
Lanolin is taken from wool, which does not require slaughter, but the label does not tell you the source, and our database notes that it can occasionally come from other animal sources. The more common practical concern is the capsule or softgel the vitamin comes in, which is often made of gelatin and brings the gelatin question with it. Fortified foods contain D3 in very small amounts, and the usual questions about their other ingredients apply.
Reading a label
Look for vegan vitamin D3, lichen-derived D3 or algal D3 on supplements, which name a plant-based source, and for vegetarian capsules made of cellulose or pullulan instead of gelatin. Cholecalciferol listed as from lanolin names the animal source. Vitamin D2 comes from yeast or mushrooms, and is another option. A halal certificate on the supplement covers both the vitamin and the capsule, and your pharmacist can help with medicines.
Practical tips
Many supplement brands now offer vegan D3 from lichen and vegetarian capsules, and these are easy to find online and in pharmacies. If you take a prescription vitamin D capsule, your pharmacist can check the capsule material. Milk and fortified foods contain very small amounts of D3, and fatty fish and sun exposure are other natural sources.
In short
In short, vitamin D3 usually comes from sheep's wool lanolin, a vegan version comes from lichen, and the capsule is often the bigger question. Vegan D3 in vegetarian capsules removes both.

What to ask the manufacturer
Ask the manufacturer in writing where the ingredient comes from: whether it is plant, microbial or animal in origin, and if it is animal, which animal and how it was slaughtered. Ask whether any alcohol was used as a solvent or carrier, and whether the product carries a halal certificate from a body your local authority recognizes. Keep the answer, because suppliers and recipes change.
