  • Question: Are 21st Century D3-5000 IU Tablets suitable for vegetarians?

    Answer: Yes, 21st Century D3-5000 IU Tablets are typically suitable for vegetarians as they are made from lanolin, which is derived from sheep's wool. However, it is wise to check the specific product labeling for any allergen information or changes in formulation. This makes them a great option for vegetarians and those looking for a powerful vitamin D supplement without animal-derived ingredients.
