The Origin

A Diagnosis. A Label. A Kitchen Table.

In 2019, our founder Elena Vásquez was told her kidneys were failing. The first thing her nephrologist said: "Read every supplement label."

I opened my multivitamin and read: Sodium 85 mg. Per capsule. I was allowed 1,500 mg per day total. My supplements were eating 25% of my daily budget before I even had breakfast.

Elena Vásquez

Founder, Mineral · Dialysis Patient

From her lab notebook, January 2021 — "Start with magnesium. No fillers. No excipients with sodium. If I can't pronounce the sodium source, it doesn't go in."

The Moment It Clicked

"My nephrologist called after my third-month labs. She said my phosphorus was stable and asked what had changed. I told her I'd switched to Mineral. She asked for the formulation sheet."

Chelated. Verified. Documented.

I've been on dialysis for three years. Every milligram matters. My dietitian and I spent six months looking for a magnesium supplement that didn't blow my sodium budget. Mineral was the first one that cleared her audit. I've been taking it for 14 months.

3× weeklylong runs, blood pressure stable

I run ultras. My cardiologist put me on a 1,800 mg sodium ceiling after my hypertension diagnosis. Every sports supplement I found had 200+ mg per scoop. Mineral's electrolyte formula is the only one I've found that actually works for long runs without wrecking my numbers.

340 mghidden sodium found and eliminated

My OB circled 'watch sodium' on my discharge sheet after a preeclampsia scare. I was taking five different supplements postpartum — iron, D3, magnesium, omega-3, B12. A Mineral nutritionist audited my stack in 15 minutes and found 340 mg of hidden sodium. We switched everything.
