Healthify your water: Contrex

Water is the healthiest drink out there. But is there a way to make water even healthier? How about natural mineral water that is fortified with calcium and magnesium? It's called Contrex and the French, who are renowned for being healthier than us North Americans, have been drinking it for years, according to Fitsugar. Like regular water, it has zero calories but unlike water, it apparently has a taste that's all its own.

I'm not against making water healthier, but I can't say I'm sold. People with a healthy diet should be getting enough calcium and magnesium anyway, so this seems like a pretty blatant marketing ploy. What do you think? Have you tried Contrex?
