For a healthy human, the best pH for drinking water is anything between 6.5 and 8.5. That’s it. That’s the whole secret. You don’t need expensive gadgets or fancy bottles. Your tap water is almost certainly fine.
Drink water that tastes good. Drink water that makes you feel happy. If your water tastes metallic or bitter, get it tested. Otherwise, stop stressing. Your body has been balancing pH since you were a tiny blob in the womb. It’s a pro at this.
So next time someone asks, “What’s a good pH for water?” just smile. Say, “Seven-ish.” Then tell them about the fish. And the rain. And the sad, lonely distilled water. You’ll sound like a genius. And you’ll have made water—finally—a little bit fun.
