I looked at the structure and it has two Carbonyl groups, C=O, so perhaps that oxygen can hydrogen bond with hydrogen on water, It also has three methyl groups, CH3, which are nonpolar, so I do not know how soluble caffeine is in water, but it surely is in coffee which is mostly water.
Hey i have a question do you need to see a doctor?

Caffeine free means that the product has "no" caffeine in it.
