Pink salt has slightly less sodium than regular table salt, but eating even a normal amount still gives you the maximum safe daily sodium limit, so any extra minerals don’t offset the health risks of too much salt.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review would determine whether replacing white salt with pink salt reduces population-level sodium intake and blood pressure without compromising iodine status.
A systematic review and meta-analysis of all randomized trials comparing sodium intake, blood pressure, and urinary iodine excretion in adults using pink salt versus iodized white salt as their primary salt source.
An RCT could determine whether substituting pink salt for white salt reduces sodium intake and blood pressure in hypertensive adults over 12 weeks.
A double-blind RCT of 150 adults with hypertension randomized to consume 5g/day of pink salt or iodized white salt for 12 weeks, with primary outcomes being 24-hour urinary sodium excretion and systolic/diastolic blood pressure.
A cohort study could determine whether pink salt users have lower blood pressure or cardiovascular events than white salt users over 10 years.
A prospective cohort of 10,000 Australian adults tracking primary salt type used (pink vs. white) over 10 years, with annual blood pressure measurements and adjudicated cardiovascular events, adjusting for total sodium intake and diet quality.
A cross-sectional survey could correlate salt type preference with sodium intake and blood pressure in a representative population.
A national cross-sectional survey of 3,000 Australians measuring self-reported salt type and 24-hour urinary sodium excretion, with blood pressure measurement and adjustment for age, BMI, and processed food intake.
A case report could document a hypertensive individual whose blood pressure improved after switching from white to pink salt.
A case report of an individual with uncontrolled hypertension who switched from white to pink salt, with documented pre- and post-switch urinary sodium and blood pressure measurements.
