The moisture condenses from warm air in contact with a cold surface
(toilet tank). So, there are some kits that let you glue pieces of
insulating foam board inside your toilet tank, and there are kits that
let you plumb in hot water to a mixing value (like the shower) so you
fill the toilet with warm water. Air flow is important, too.
