vitamin D? unless you live within 10 degrees of the equator "the sun" is not a valid answer.
The most available form of vitamin D comes from extracting the oil from sheep's wool/skin using chemicals (soap is a chemical, for the record.) Yes, it is possible to get a much weaker form of D from mushrooms, but not as they arrive, regardless of packaging. they have to be left outside in the sun for at least 8 hours, but ideally "two full days in the sun", cap-side up (facing the sun), and then a standard mushroom will have enough D2 for the average adult, maybe. I don't know the specific conversion from D2 to calciferol or whatever.
And before anyone decides to cite 30ng/ml or whatever as "recommended", i disagree, 90-105ng/ml is more "ideal" and 500IU of vitamin D supplements aren't going to cut it. it's 1 IU per 10 grams of body mass (roughly).
i can do this all day, it's a waste of both of our time. As lovely as vegetarian/veganism is in the abstract, the entire planet cannot be vegan any more than the entire planet can subsist off insects.
Vegan D3 is derived from algae, I believe.
My vegan diet involves a lot of beans, rice, ..., which all require considerably less input than meat does. A bag of beans costs so very little, lasts so long, and is healthy. Meat and dairy are luxuries that come at the cost of pretty horrific treatment for a great number of animals.
