Below are "a few ideas" listed from the article (direct quote): 1- mushrooms that have been exposed to ultraviolet light (11Trusted Source) 2- Take fish oil supplements such as cod liver oil 3- Eat fatty fish twice a week (12Trusted Source) 4- Choose milk or orange juice that’s been fortified with vitamin D 5- Eat some eggs and butter (13Trusted Source) 6- Spend at least half an hour in the sun daily, if possible My thoughts on their recco: Option 6 is the typical US doctor prescription before vitamin supplements and seems the most reasonable, though depends on your location. Options 3 and 5 are legit options and worth noting. Not sure if the portion sizes would be a financial detriment to many though. Option 2 and 4 essentially seem like taking Vitamin D supplements. Option 1 is huh? Who has a UV gun for mushrooms? Do stores do this automatically?
