Bottles of Vitamins?

Question

I just bought a bottle of vitamins and it has a small cylindrical white cube sitting on top of the pills in the bottle. Does anyone know what this is and why they put it in the bottle with the vitamins I bought?

Answer 1

That is silica gel and is used to absorb excess moisture to keep the vitamins fresh longer

Answer 2

I don't know exactly what it is but it is there to absorb whatever

moisture may be in the bottle to keep the vitamins fresh.
