Supplements and blood pressure medication.

ACE inhibitors, ARBs, beta-blockers, calcium channel blockers and the supplements with documented BP effects.

Blood pressure medications fall into four common classes (ACE inhibitors like ramipril, ARBs like losartan, beta-blockers like bisoprolol, calcium channel blockers like amlodipine) plus diuretics like furosemide. Several supplements lower blood pressure on their own, which is sometimes useful and sometimes risky depending on baseline control.

The additive-BP-lowering supplements with the strongest evidence are magnesium, garlic extract, hibiscus, CoQ10 and beetroot/nitrate. On a well-controlled regimen these can be helpful; on a borderline-low BP they can tip into orthostatic hypotension. Potassium warrants special attention: ACE inhibitors and ARBs both raise potassium, so a potassium supplement (or a high-potassium multi) needs blood-level monitoring to avoid hyperkalaemia.

How we decide

How we grade severity, choose what's in scope, and what we exclude.

Every call on this page is reasoned. We publish the full rubric for severity tiers, the medication inclusion logic, the evidence grades we accept, and what we deliberately leave out. About three thousand words. Worth reading once if you use this tool more than occasionally.

The full report

A full supplement review, built around you, not a generic stack.

The free checker answers one interaction question at a time. A Distil report reviews the bigger picture: your goals, diet, medications, current supplements and any blood results you provide, then shows what appears worth keeping, changing, adding or leaving out.

  • what your diet already covers, so you are not adding a capsule for something food is already handling
  • which evidence-graded compounds are worth considering for your goals, and which were considered but left out
  • what to keep, change or stop from what you already take, plus the order to introduce anything new
  • how your medications and complete supplement stack fit together, with daily timing and a clear point for reassessment

The interaction check is one section of the full report. You also get the reasoning behind each recommendation and the evidence references used.

Distil's interactions database is reviewed and updated every quarter. We grade evidence transparently and publish our methodology, including every database change, at /about/methodology. This tool is information, not a substitute for clinical judgement. If you take medication and supplements together, your GP or pharmacist can review your full regimen against your medical history. If you want a full personalised stack reasoned against this same database, the Distil report is the next step up.
