Are Vitamin- and Mineral-Enhanced Waters Good for You?

Adding vitamins or minerals is an easy and inexpensive strategy to make water appear healthier. The cost of a ten-year supply of a day’s worth of vitamin C from China, for example, runs only about $1 wholesale.


B vitamins are especially popular among drink manufacturers. Just about every 20 oz. bottle of Glacéau Vitaminwater and Vitaminwater Zero, for example, delivers the Daily Value for B-5 (pantothenic acid), B-6, and B-12. Yet in dozens of studies, people who took B vitamins—or high doses of other vitamins—every day for years were typically no better off than people who took a placebo. Maybe these waters should be called placebo-enhanced instead.
