If you live in an area where it isn’t sunny very often, you might need to look at other ways of getting Vitamin D. For example, there are supplements out there that you can take.

Other foods that you can add to your diet is eggs, sardines, shrimp, milk, and cod.
They say you should try and get 30 minutes of sunlight each day to get your recommended daily allowance of vitamin D.

Because vitamin D is a stable compound. You can cook foods and store it long term and it won’t significantly reduce the potency. The production of vitamin D precursors in the skin can decrease with age, so it’s very important that you make sure you are getting enough in your daily diet.
