We don't ask you to take our word for it. Independent labs test our water — here's what they found.
pH LEVEL
pH 9.7–10.0
Formulated with proprietary minerals and electrolytes, then tested prior to bottling and held between 9.7 and 10.0 — every batch, not just the first one. Publishing a range this narrow is the point: it is what consistency looks like on paper.
PURITY
TDS 35 — The Lowest
Total dissolved solids of just 35 ppm — deep inside the "ideal drinking water" zone, purer than typical premium and alkaline waters.
FORMULATION
Physician-Formulated
Developed by physicians with a proprietary mineral matrix, bottled BPA-free through a 16-stage purification process.
LAB VERIFIED
Ten Polymers, Non-Detect*
Independently tested for the ten plastics found in drinking water — polyamide, PC, PE, PET, PMMA, PP, PU, PS, PVC and PTFE. Every one non-detect, 20–540 µm.
Microplastics* · Independently Lab Tested
Ten polymers screened. Every one non-detect.

pH Level · Higher Is More Alkaline
Most alkaline water stops at 9.5. Ours doesn't.
Typical bottled water · ~7–8
Premium bottled water · ~9
Leading alkaline brands · 9.5
ALKA · pH 9.7–10.0
pH is logarithmic — every whole point is a tenfold change. ALKA's 9.7–10.0 range sits roughly 1.6× to 3× more alkaline than the 9.5 most premium alkaline brands target, and 50–100× more than pH 8.
Dissolved Solids (TDS) · Shorter Bar = Purer Water
The shortest bar wins.

0–50 PPM is the "ideal drinking water" zone. ALKA sits comfortably inside it at 35 — most bottled water doesn't come close.
Microbiology · Independently Lab Tested
Zero bacteria. Verified three times over.
Third-party lab testing across three independent samples pulled from the same production run — same day, same batch.
