Question: Is it important to get vitamin D sulfate specifically from the sun?
This is a question asked live during the February 15, 2023 AMA.
Short Answer: It is important to get morning outdoor sunlight as close to every day as possible for your circadian rhythm, and to get some exposure to unprotected sunlight during the day when UV is available, but at doses less than needed to cause reddening, and it is equally important to always avoid burning. There are many reasons for this, and the cholesterol sulfate hypothesis — to which the vitamin D sulfate hypothesis is peripheral — is an interesting and worthy hypothesis but should not be the final arbiter of your sun exposure habits.
