Sometimes i work overnights and dont see alot of sunlight. is it true that vitamin d supplements may be beneficial to make up for it? thanks

Yes: The main source of Vitamin D is exposure to the sun, esp. in the spring and summer. In the fall and winter we can't get any D from the sun (unless living in the tropics) so everyone should take D in the fall and winter even if they get plenty of sun. I advise at least 2000 iu of D3 a day to get optimal levels. See https://tinyurl.com/y8uzz6sv
