I don't know. But it is my understanding that how high up in the sky the sun is matters a lot. Ie 5 pm sun is going to be a lot less effective than midday sun, because UV-B light has to go through more of the atmosphere.
>Does it scale up to a limit?
Yes, because sunlight only really makes a precursor to vitamin D. Ie you can't overdose on vitamin D from sunlight.
- westurner 3y agoPrompt: generate a dataframe that lists: the amount of sunlight exposure by time, given the UV index, that corresponds to a given dose of Vitamin D in IUs, and milligrams (for each and/or an average patient profile) How much vitamin D supplementation results in the same serum level as sunlight exposure?
