This is more out of curiosity than an actual need to know. I've just noticed that the lid for my tube of Berocca makes a fun shaking sound, like a mini maraca. Any clues as to what's in there and what purpose that could possibly serve?
I guess it would be silica gel or something to absorb moisture
Makes sense!
