The Upside-Down Diet
Sodium vs. Potassium: Why the Ratio Matters
Research shows the modern U.S. diet tends to run high in sodium and low in potassium. Most adults exceed recommended sodium limits while falling short on potassium, a pattern linked with higher cardiovascular risk and elevated blood pressure outcomes. The key takeaway: it’s not just the numbers, it’s the sodium-to-potassium balance.
Our formulation focus
All fiz products are formulated at a 0.27 sodium-to-potassium ratio, to support a more favorable electrolyte balance. That ratio aligns with, and is even lower (better) than, prevailing guidance referenced by the FDA and WHO.
We believe paying attention to the sodium-to-potassium ratio is a smart evidence-backed approach to nutrition. Here are a few credible resources on the topic:
