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 is one specific finding in this system. Your Genomic Lifestyle Optimization Report shows where your variants place you on the micronutrients and strategic supplementation spectrum — and what you can do about it: it renders as a dark card with a color marker calibrated to your variants, opening with the gene mechanism and closing with a practical, mechanism-led recommendation.

Choline Intake Needs
Choline demand varies 2–3× between people. Higher-need individuals see noticeable improvements in focus, fat metabolism, and liver function from eggs or supplementation—while others coast fine without thinking about it.
Read insight →Copper Levels
Copper 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.
Read insight →FUT2 Status
"Non-secretor" status changes how you absorb B12 and shapes your gut microbiome. This explains why some vegetarians stay healthy for decades while others crash within years—same diet, very different biology.
Read insight →Folate Intake Needs
Folate requirements vary widely—especially during pregnancy, high stress, or rapid cell turnover. Knowing yours prevents the subtle deficiency that quietly affects mood, energy, and long-term health without obvious symptoms.
Read insight →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.
Read insight →Iron Intake Needs
Iron 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.
