Why people use it
Most vitamin D3 supplements are made from lanolin, a byproduct of sheep's wool, making them unsuitable for a vegan diet -- lichen offers a plant-based source of the identical D3 molecule rather than the less-effective D2 alternative.
- ✓Vegan-compatible vitamin D3 supplementation
- ✓Correcting or preventing vitamin D insufficiency on a plant-based diet

What the evidence says
D3 is well-documented as more effective than D2 at raising and maintaining blood vitamin D levels; lichen is a genuine, chemically-equivalent vegan source of D3 itself, distinct from the traditionally recommended vegan fallback of D2.

Safety note
Know before you use it
Vitamin D is fat-soluble and can accumulate to harmful levels at high doses over time, unlike water-soluble vitamins that are more easily excreted; supplementing beyond standard label doses without a specific reason and clinical guidance is not advisable. Anyone with a health condition affecting calcium metabolism, or taking medications that interact with vitamin D, should discuss dosing with a clinician.
