The oceans have helped sustain life on Earth for billions of years and will likely continue to do so far into the future. Oceans have an abundance of minerals like calcium, phosphorus, magnesium, iron, and copper, which are essential nutrients for living organisms. In Japan, deep-sea water (or DSW) is commonly used for drinking, cosmetic purposes, and as seasoning. Recent evidence indicates that DSW has numerous health benefits. However, the exact mechanism behind these benefits is not known.
