Vitamin D level listed as 4.9. Very scared.?

i don't know my vitamin d levels, i just know that it's very low so im taking vitamin d supplements for that. I try to take them everyday but sometimes i forget to because on the bottle it says to take them while i eat so there isnt a specific time i take them. & i have vitiligo, so that could be why i have vitamin d low levels and in my case i have it in one private area so i'm not really affected by the sun like another person with vitiligo could be affected with it. I'm not so sure what foods for you to eat though just look on your food labels of your food at home and it should tell you how much of a percentage of vitamin d is in there if there is any, like in the cinnamon toast crunch i eat there is 25% vitamin D in there...Hope i've helped some:)
