4,000 Adults
The analysis pooled baseline data from three similarly designed randomized trials, covering 4,000 adults.
Participants reported whether they were aware of and currently used low-sodium salt substitutes.
Awareness and Use
Thirty-two percent reported awareness and 11.7% reported current use.
The gap shows that market availability does not automatically translate into widespread adoption.
Urinary Electrolytes
Participants who used or were aware of low-sodium salt had lower estimated 24-hour urinary sodium than those who were unaware.
The study links real-world behavior outside a dedicated intervention with objective electrolyte biomarkers.
