Is Expensive Bottled Water Actually Better for You?

Premium bottled water brands differ in mineral content, source, and pH. No evidence shows that expensive water hydrates better than ordinary water. Calcium, magnesium, and sodium are absorbed in ionized form, with intake depending on concentration and volume consumed. High total dissolved solids or alkaline pH labels do not guarantee safety or health benefits. Consumers should examine specific mineral concentrations listed on the bottle.
