Some mushrooms are UV-treated to increase vitamin D2. For sourcing, the useful questions concern processing, identity and measured content.
NIH ODS notes that mushrooms contain variable amounts of vitamin D2 and that some commercial mushrooms are UV-treated to increase it. “Mushroom” therefore identifies a food, not a fixed vitamin D specification.
The fact can make an engaging introduction, but “mushroom-derived” is insufficient for a purchasing decision. Request the species, part used, processing description, composition and declared vitamin D2 basis, linked to the actual material code.
Ask about carriers, blends and any process used to adjust the declared content. Whole mushrooms, dried powder and a material supplied to a defined assay are different quotation bases.

Align units and calculation bases before comparing samples or batches, then review sampling and analytical documentation. Content per gram of ingredient, per finished serving and per bottle answer different questions. Keep them in separate worksheet columns.
Connect the proposed material input, other ingredients, serving weight and content calculation so technical and label reviewers can check them. Do not transfer an ingredient-sheet number directly to the finished label before confirming what it represents.
If the concept includes vegetarian or source requirements, obtain appropriate origin and processing statements and check carriers and other ingredients as well. An origin story does not establish that the complete formula meets the intended conditions.
This is a food and sourcing fact, not a home irradiation procedure or an intake recommendation. Placing the story alongside verifiable specifications makes it more useful in an OEM discussion.
