All food and drinking packaging must have the real size of the food with picture. All packaging must inform if there is any man-made addiction in the product for instance, spring waters in the manufacture, they add calcium in the water, which is man-made, It must show if any man-made substance was added to the drink.
You might want to do a little more research-
Calcium (Atomic Symbol Ca) is a naturally occurring mineral, and can be found in several food items.
Every food and drink packaging already is required to indicate ingredients, and most have a nutrition facts label, which includes vitamin and mineral content - your spring water example doesn’t because it likely doesn’t have any vitamins or minerals added (unless they specifically call it out) - My bottle of spring water just says it was bottled from specific springs in Texas, and nothing else, and as far as I know, that’s all I’m getting.
