Blood Pressure Sensitivity to Sodium Intake
About half of people see their blood pressure rise with salt; the other half are neutral. This decides whether low-sodium is medically mandatory or an unnecessary restriction that just makes food taste worse.
What this measures
How your DNA shapes blood pressure sensitivity to sodium intake.
ACE codes for angiotensin-converting enzyme — central to blood pressure regulation through the renin-angiotensin system. AGT (angiotensinogen), ADD1 (an actin-binding protein in kidney cells), CYP11B2 (aldosterone synthase), and GNB3 all shape how strongly blood pressure responds to dietary sodium.
Carriers of common ACE, AGT, ADD1, CYP11B2, and GNB3 variant combinations are associated with anywhere from minimal blood-pressure response to dietary sodium ("salt-resistant") to strong response ("salt-sensitive"). Salt-sensitive carriers tend to see clinically meaningful blood pressure shifts within days of changing sodium intake. Salt-resistant carriers can eat substantially more sodium without measurable cardiovascular impact.
Potassium intake from fruits, vegetables, and legumes blunts sodium’s blood-pressure effect across nearly all variant patterns. Magnesium status influences vascular reactivity. Hydration, alcohol, sleep, and physical activity all shift the sodium-pressure relationship. Processed foods deliver most of the dietary sodium in modern diets; whole-food cooking gives clients meaningful control over total intake.
"Salt is the enemy" works for some clients and is largely irrelevant for others. Which combination of variants you carry decides whether sodium restriction is one of the top blood-pressure interventions or whether the focus belongs elsewhere — on potassium, weight, sleep, or stress.

Blood Pressure Sensitivity to Sodium Intake renders as a dark-background card with a color marker calibrated to your specific variants. The card opens with the gene mechanism, shows your result at a glance via that marker, and closes with a practical, mechanism-led recommendation — what to eat, what to time, what cofactors to support.

In context
Minerals: the 7-insight cluster.
Blood Pressure Sensitivity to Sodium Intake is one finding in a tightly-related cluster. Mosaic sequences the other 6 alongside it so you see the whole biology — not an isolated data point.
- Copper LevelsCopper is a behind-the-scenes player—affecting iron absorption, collagen production, and antioxidant defense. The catch: both deficiency and excess cause problems, and they look surprisingly similar. Your regulation pattern tells you which direction to watch.
- Iron Intake NeedsIron absorption and loss rates differ dramatically between people. Knowing yours prevents both anemia (too little) and accidental iron overload (too much)—two problems with opposite solutions that feel confusingly similar.
- Magnesium Intake NeedsOver 300 enzymes depend on magnesium, yet requirements vary widely. Higher-need individuals often feel dramatic improvement in sleep, stress response, and muscle function from optimized intake—it's one of the highest-impact changes available.
- Propensity to Accumulate Excess IronHemochromatosis gene variants cause silent iron buildup that damages the liver, heart, and joints over decades. The fix is remarkably simple—regular blood donation. But you have to know you need it. Early knowledge allows easy prevention.
- Selenium Intake NeedsSelenium requirements for thyroid conversion and antioxidant defense vary 2–3×. This determines whether a couple of Brazil nuts weekly is enough—or you need consistent supplementation to hit optimal levels.
- Zinc LevelsZinc absorption and retention differ markedly between people. Immune function, testosterone production, wound healing, and taste perception all improve once you hit your personal requirement, which may be higher than generic recommendations suggest.
Questions people ask
About Blood Pressure Sensitivity to Sodium Intake.
- How does my DNA influence blood pressure sensitivity to sodium intake?
- Where vitamin meets variant: the MTHFR methylation cycle (folate), the GC/CYP2R1/VDR vitamin-D activation pathway, the TMPRSS6/HFE iron-handling network, and the genes that determine which forms of B12, magnesium, and choline your body actually absorbs versus ignores.
- What kind of test do I need to see my Blood Pressure Sensitivity to Sodium Intake result?
- Whole-genome sequencing at 30× clinical depth. Consumer SNP-chip tests like 23andMe or AncestryDNA only read ~0.02% of your DNA and miss most of the variants this analysis needs. Mosaic reads all 3 billion base pairs and produces the full 108-insight report.
- How is Blood Pressure Sensitivity to Sodium Intake different from clinical lab testing?
- Clinical labs measure downstream biomarkers — blood levels, hormone values, metabolic byproducts — at a single point in time. Genomic insights like Blood Pressure Sensitivity to Sodium Intake reveal the underlying variant that shapes the biology, which is constant for life. The two are complementary: labs show the current snapshot; genomics shows the long-term tendency and where lifestyle leverage is highest.

Folic Acid Conversion Efficiency
Common variants reduce the conversion of synthetic folic acid (in supplements and fortified foods) into active methylfolate. If you're affected, standard prenatals and "enriched" bread aren't doing what you think. Methylfolate does.
