Supplement / capsule ingredient
Is Vitamin D3 halal?
The most common supplement in the Muslim world has a sheep in its supply chain. D3 starts as lanolin washed from wool — and whether that needs a halal-slaughtered sheep is where the positions split.
Most D3 is made from lanolin (sheep's wool grease). One documented position permits lanolin derivatives because sheep wool is pure; stricter certifier guidance requires the sheep to be halal-slaughtered or the source traceable. Lichen-based vegan D3 avoids the question.
The detail
Vitamin D3 is synthesised from lanolin, the grease scoured from sheep's wool. MuslimMed's medical-fiqh guidance holds that sheep wool is pure and lanolin-derived vitamin D is permissible, provided the product is free of impurities. HalalExpo's checker records the certifier position: lanolin is halal from living or halal-slaughtered sheep, mashbooh otherwise, with JAKIM requiring traceability. Because the wool comes from shearing rather than slaughter, the permissive view treats it like milk — a product of a living animal — while the strict view wants documented sourcing. Vegan D3 from lichen is now widely available and settles it. The second check is the capsule shell (see gelatin capsules).
What the sources say
Sheep wool is considered to be pure, therefore the topical use and consumption of products derived from it (such as lanolin) is considered to be permissible.
Halal if sourced from living sheep or halal-slaughtered sheep. Mashbooh if from non-halal slaughter. ... JAKIM requires traceability to confirm sheep source.

How to check it yourself
Look for 'vegan D3' or 'lichen-derived' to sidestep the question, or a halal-certified D3 (several IFANCA-certified products exist). Then check the softgel shell separately.
