Apprently this vitamin D3 is sourced from wild-harvested lichen (that moss you see growing on rocks/trees, which is a hybrid organism of algae and a fungi). That makes the ingredient a vegan alternative to other animal-based vitamin D supplements that are usually made from lanolin (sheep). Dosage-wise I take 1 capsule every few days to supplement the vitamin D I make from sun exposure.
I have so many vegan vitamin D tried but all have some smell this one absolutely not !! I like this product and recommend it👍👍👍
