Careful where you store your vitamins

Where you keep your vitamins -- may determine how effective they are!

A new study shows high humidity levels -- like those in bathrooms and kitchens -- can degrade the potency of Vitamin C and other vitamins, even if the cap is on tightly.

Researchers found Vitamin C can break down within one week when high amounts of humidity and moisture are added to the bottle as it's opened and closed.

The first sign a vitamin has deteriorated is brown spots.
