If you're trying to understand your options for high blood pressure, including after several approaches haven't been enough, you're in the right place.
That's a fair reason to be here.
Hypertension: where each option sits in the evidence
This map shows medicines, salt substitutes, eating patterns, sodium, exercise, weight-focused diets, and popular supplements as different kinds of decisions. Lowering blood pressure is not automatically the same as proven protection from heart attack, stroke, or death. Some options have that harder evidence. Others mainly show blood-pressure change.
Use this map to understand the options and prepare better questions for your clinician. It isn't a guide to starting, stopping, or changing treatment on your own.
How to use this page
This is a landscape of what has been studied, not a prescription.
Blood-pressure medicines stay on the map. Lifestyle options are calibrated by what they were shown to do. A potassium-enriched salt substitute is not the same decision as cutting back on sodium.

Lowering blood pressure is not the same as proven protection from heart attack, stroke, or death. Keep that distinction in mind as you move through the map.

These are common decisions people face with high blood pressure. The evidence isn't the same kind for every option. Some pages are about heart attack, stroke, and death. Others are mainly about blood-pressure change.
Hard cardiovascular outcomes
Blood-pressure medicines and a defined salt substitute have evidence on major events. They are different decisions.
- Do blood-pressure medicines prevent heart attacks and strokes? How low should my pressure go? A very large trial base shows that lowering blood pressure with medicines reduces major cardiovascular events. Guidelines still disagree about diagnostic cutoffs and treatment targets. Intensive targets from landmark trials come with more side effects and apply to the people who were studied.
- What is a potassium-enriched salt substitute, and is it the same as cutting salt? A defined product (about 75% ordinary salt and 25% potassium salt), not a tip to eat more bananas. In the major trial that studied them, they reduced stroke and other serious events in the settings and people studied. That is a different decision from cutting sodium alone.
Eating and sodium
Pattern-quality eating, cutting sodium, and weight-focused diets are related but not the same decisions.
- Does DASH work? Is plant-based one diet? DASH has stronger blood-pressure evidence than some other patterns. Plant-based is not one diet: lacto-ovo evidence is stronger than vegan in the pattern review used here, and Mediterranean effects are more modest. A pattern that lowers blood pressure is not automatically proven to prevent heart attacks or strokes.
- Does cutting sodium lower pressure? There is a clear blood-pressure dose-response in longer trials. That is not the same as the salt-substitute event findings.
- Is losing weight the same as eating a DASH-style pattern? Weight-reducing diets can produce meaningful average weight loss. Blood-pressure change in the hypertension diet review is less certain, and that package did not settle mortality. This is not the same page as pattern-quality eating.
Movement
Several kinds of training can lower resting blood pressure. Mode rankings are not event rankings.
Popular supplements
Modest, mixed blood-pressure signals. Not proven event prevention, and not a replacement for indicated care.
