I like to drink multivitamin juice similar to this, but it takes me a 3 or 4 days to drink whole carton.
How long will these added vitamins last, when kept in the refrigerator?
How long will they last, when I keep the juice in a room temperature?
I'm not asking how long the juice will be safe to drink, but only about the vitamin content (A, C, and various from the B group).

If you drink up your juice within 3 to 4 days, the vitamin content will not decrease significantly. Usually, if properly stored, vitamis last for years.
