Give me a regime of supplements that can help reduce blood pressure

The burden of proof is on the intervention, not on your blood vessels.

You want a supplement regimen for blood pressure. Let me start with what is actually proven, then what is plausible but thin, then what is marketing dressed as science. And I will not pretend the evidence is stronger than it is.

First principle: blood pressure is a colloid problem as much as a plumbing problem. Your blood is a suspension of red cells, platelets, and proteins in plasma. When that suspension loses its electrical charge, the zeta potential, cells stack and sludge. Flow slows. The heart pushes harder. Viscosity rises. That is one reason why hypertension tracks with inflammation, poor hydration, and metabolic stress, not just "stiff arteries." So the best supplements are the ones that restore flow and charge, not just the ones that block a receptor.

The strongest evidence, the kind that survives replication, is for magnesium. About 300 to 400 milligrams of magnesium glycinate or citrate daily lowers systolic pressure by roughly 2 to 4 points in people who start deficient, which is most people eating processed food. The mechanism is direct: magnesium relaxes vascular smooth muscle and supports the sodium-potassium pump that keeps the cell's charge stable. This is not a blockbuster, but it is real, cheap, and safe. The studies are small but consistent, and the mechanism is biochemically sound. Confidence: moderate.

Potassium is next. Not a supplement exactly, but a mineral. The DASH diet works largely because it is high in potassium and low in sodium. If you cannot eat enough beans, greens, and potatoes, a potassium citrate supplement at 500 to 1000 milligrams daily can help, but only if your kidneys are normal. Do not take potassium supplements if you have kidney disease or take an ACE inhibitor or ARB, because you can push potassium into dangerous territory. The evidence for potassium lowering blood pressure is strong, but the dosing is a knife edge. Confidence: high for the mechanism, high for the caution.

Coenzyme Q10, or ubiquinol, has a decent track record for lowering systolic pressure by about 3 to 5 points in people with hypertension, likely because it improves mitochondrial function in the endothelium, the lining of your blood vessels. The studies are small and mostly industry-funded, but the effect is consistent across trials. The problem is dosing: you need 200 to 300 milligrams of the ubiquinol form, which is expensive, and it takes eight to twelve weeks to see the effect. Confidence: moderate, with the caveat that the evidence base is thin and conflicted.

Now the weak stuff. Garlic extract, specifically aged garlic extract at 600 to 1200 milligrams daily, shows a modest 2 to 3 point drop in systolic pressure in meta-analyses. The mechanism is real: allicin increases nitric oxide, which relaxes vessels. But the trials are short, mostly under twelve weeks, and the effect fades when you stop. It is not a treatment, it is a nudge. Confidence: low to moderate.

Omega-3 fatty acids, fish oil at 2 to 3 grams of combined EPA and DHA, lower blood pressure by about 2 points, but only in people with elevated pressure, not in normotensive people. The effect is real but small, and high doses can thin your blood and interact with anticoagulants. Confidence: moderate for the effect, high for the caution.

What I will not recommend: vitamin D, unless you are deficient, because the trials show no consistent blood pressure benefit in people with normal levels. L-arginine or L-citrulline, because the oral bioavailability is poor and the trials are mixed. And anything claiming to "cleanse" or "detox" your arteries. That is nonsense.

Now the honest part. No supplement regimen replaces the two interventions with the strongest evidence: reducing sodium to under 2000 milligrams a day and walking thirty minutes most days. Those two alone lower systolic pressure by 5 to 10 points, more than any supplement on this list. If you are on medication, do not stop it to try supplements. If you are not on medication and your pressure is above 140 over 90, see a clinician who will actually measure you properly, not one who recites the schedule.

The evidence for supplements is real but modest. Magnesium and potassium are the foundation. CoQ10 and garlic are adjuncts. Everything else is noise. And if anyone tells you a supplement is a cure, they are selling you something, not treating you.
