I get filtered water from the tap and add powdered magnesium, potassium, and sodium to the water when I drink it.

Depending on your individual needs, you can add others powdered vitamins/minerals as well. It’s worth getting your levels checked to see what you need so you don’t overdo it and also looking into how certain supplements affect other things.

Ie: magnesium depletes calcium

and vice versa, zinc depletes copper and vice versa, etc.

When getting these minerals from foods, typically they’re balance but soil, food, and water are largely devoid of nutrients nowadays compared to 50+ years ago.
