Common questions

Is Arrowhead 100% Mountain Spring Water healthy?

Arrowhead 100% Mountain Spring Water scores 35/100 on Tallow — our avoid band. That number comes from what is on the label: the ingredients, how processed it is, and what it is packaged in, plus lab results from its product family, Arrowhead Mountain Spring Water (still). It is not a verdict on your diet — Tallow does not weigh calories, portion size or how often you eat it, so a high score means the ingredients are clean, not that the food is unlimited.

What is in Arrowhead 100% Mountain Spring Water?
