You can get huge jugs of the same stuff at Sprouts. It's basically mineral water, but the bottles are nice. I gave it 5 stars because it is extremely useful for those of us who have an electrolyte imbalance due to thyroid troubles. Just plain water does not hydrate.
So yes, it does help but the price point is not worth it in my opinion.
The taste is fine to me because I'm use to distilled water with added electrolytes but for a first time consumer, it will taste a little weird.
