If you're stocked up on vitamins, it might be time to check the expiration dates on those bottles.

News 12's consumer reporter Janice Lieberman gives us The Real Deal on when it's time to clean out your cabinets.

The Food and Drug Administration does not require vitamins and dietary supplements to have expiration dates, compared to over the counter and prescription drugs. However, most manufacturers choose to display a best use by date, which illustrates that their vitamins should maintain 100% potency up to that date.

Not all vitamins have the same shelf life. Water soluble vitamins, like B-12 and C, tend to lose their potency quicker. Fat soluble vitamins like A, E, D and K typically maintain their potency.

Experts also say that you have two years beyond the expiration date, although the potency might not be as effective.

To keep your vitamins lasting longer, store them in a cool, dry place. A bathroom cabinet is not a good choice. Excessive heat and moisture can cause the vitamins to lose their potency faster.
