When your doctor tells you to reduce sodium to lower blood pressure, the advice is not wrong – but it is incomplete. Sodium and potassium operate in a ratio that determines blood pressure more reliably than either mineral alone. The typical Western diet has inverted this ratio: too much sodium, too little potassium. Correcting the ratio matters more than eliminating sodium.

Sodium and potassium are the primary ions that determine fluid balance inside and outside cells. Sodium is predominantly extracellular; potassium is predominantly intracellular. This gradient – maintained by the sodium-potassium pump – drives cellular nutrient uptake, nerve signal transmission, and muscle contraction. When the ratio shifts too far toward sodium, fluid retention and vasoconstriction follow.

The sodium-potassium ATPase pump – the enzyme that maintains this gradient – is directly influenced by thyroid hormone function. A sluggish thyroid impairs the pump’s efficiency, making it harder to maintain the right ratio inside cells even when dietary intake is appropriate. This is why people with subclinical hypothyroidism often have elevated blood pressure that does not respond well to standard dietary interventions.

The Liver Connection

The liver metabolises hormones and regulates fluid balance through aldosterone and the renin-angiotensin system. When liver function is compromised – through fatty liver, alcohol exposure, or chronic inflammation – these systems can become dysregulated, causing sodium retention and elevated blood pressure independent of dietary sodium intake.

Liv Pure supports liver function through targeted compounds – including milk thistle, glutathione precursors, and N-acetyl cysteine – that improve the liver’s ability to regulate the systems controlling blood pressure. This is not about forcing sodium excretion through diuretics. It is about restoring the liver’s capacity to regulate fluid balance and hormone metabolism properly.

The Potassium Gap

Modern diets are potassium-deficient relative to historical norms and relative to sodium. The ratio of potassium to sodium in a typical Western diet is approximately 1:3 – the opposite of what human physiology expects. Hunter-gatherer diets typically had ratios of 10:1 or higher. The gap is enormous, and it has direct consequences for blood pressure.

The simplest intervention: eat more potassium-rich whole foods. Avocados, spinach, sweet potatoes, bananas, and coconut water all contain significant potassium. Reducing processed food – the primary source of sodium – automatically shifts the ratio. Most people who make this shift see measurable blood pressure improvements within weeks.

Test your ratio rather than just your sodium. A serum sodium-potassium ratio above 4:1 is associated with elevated blood pressure. If you have elevated blood pressure and have not had these markers checked together, request both. Addressing the ratio – by increasing potassium intake and reducing processed food – is often more effective than sodium restriction alone.
