I take centrum gummy multivitamins that come in a clear bottle like [this](http://mms.businesswire.com/media/20150521005774/en/468659/5/Centrum_MultiGummies_Product_Image.jpg). I worry that the light will destroy the vitamins inside. Is this a concern?

Keep them in a closed cabinet if you are concerned, otherwise be assured that the packaging is appropriate for the shelf life.

WAG: Depends on the vitamin.

Second WAG: If light destroyed them, the manufacturer would package them in non-translucent container.
