Taurine and medications.
Taurine is in the Distil supplement database, evidence Grade B. The page below lists every medication we have explicitly assessed it against.
Taurine is an amino acid the body makes and also gets from animal foods, with roles in heart function, electrolyte balance and antioxidant defence. The clearest evidence is Grade B for cardiovascular and exercise outcomes: Tzang's 2024 meta-analysis of 20 trials found taurine lowered blood pressure and heart rate and improved heart pump function in heart failure patients. The longevity angle rests on Singh's 2023 work suggesting taurine declines with age, but that hypothesis is now contested: Fernandez 2025 in Science found taurine did not decline with age at all, staying stable or rising across human cohorts, primates and mice, so it is best treated as an unresolved question rather than an anti-ageing benefit. Typical doses are 1 to 3g daily, with 1 to 2g for cardiovascular goals or before endurance exercise. Vegans get essentially no taurine from diet, which makes supplementation more relevant for them, a point worth flagging. It pairs well with magnesium for electrolyte balance. The interaction to know is additive: taurine tends to lower blood pressure on its own, so taken with blood pressure medicines such as amlodipine, ramipril, losartan or bisoprolol the effects may stack, and it is worth flagging to your GP and keeping an eye on readings rather than assuming the two simply add up safely. Taurine is very well tolerated, with occasional mild stomach upset the only common complaint.
Below are the 10 documented pairs we have explicitly assessed for Taurine: 10 amber. The pairs cluster around 1 mechanism: Additive blood-pressure lowering. Every call is cited to either a clinical reference (PMID) or the British National Formulary. Anything not listed here is either still to be assessed or beyond our database scope. The checker beneath surfaces assessments by medication, and the missing-item form at the bottom of the page routes any uncatalogued medication into our next curation pass.
Documented interactions
Last reviewed 15 June 2026. Each interaction below lists the evidence its assessment drew on: some rest on studies of the exact pair, others on mechanism evidence, where a citation may support one part of the reasoning rather than the exact combination. The evidence line on each entry says which.
Additive blood-pressure lowering
Amber Does interact with Amlodipine?
Taurine tends to lower blood pressure on its own, and amlodipine lowers it by relaxing blood vessels. Taken together the blood-pressure effects may stack, so watch for dizziness on standing, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Bendroflumethiazide?
Taurine tends to lower blood pressure on its own, and bendroflumethiazide is a water tablet used to lower it. Taken together the blood-pressure effects may stack, so watch for dizziness on standing, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Bisoprolol?
Taurine tends to lower blood pressure and heart rate a little on its own, and bisoprolol is a beta blocker that also lowers both. Taken together the effects may stack, so watch for dizziness on standing or feeling unusually tired, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Candesartan cilexetil?
Taurine tends to lower blood pressure on its own, and candesartan lowers it by blocking the angiotensin receptor. Taken together the blood-pressure effects may stack, so watch for dizziness on standing, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Clonidine?
Taurine tends to lower blood pressure on its own, and clonidine lowers it too. Taken together the blood-pressure effects may stack, so watch for dizziness on standing, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Guanfacine?
Taurine tends to lower blood pressure on its own, and guanfacine lowers it too. Taken together the blood-pressure effects may stack, so watch for dizziness on standing, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Indapamide?
Taurine tends to lower blood pressure on its own, and indapamide is a water tablet used to lower it. Taken together the blood-pressure effects may stack, so watch for dizziness on standing, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Lisinopril?
Taurine tends to lower blood pressure on its own, and lisinopril lowers it by blocking the angiotensin-converting enzyme. Taken together the blood-pressure effects may stack, so watch for dizziness on standing, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Losartan?
Taurine tends to lower blood pressure on its own, and losartan lowers it by blocking the angiotensin receptor. Taken together the blood-pressure effects may stack, so watch for dizziness on standing, especially in the first couple of weeks. The added effect tends to be modest. If symptoms appear, tell your GP.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Ramipril?
Taurine tends to lower blood pressure on its own, and ramipril lowers it by blocking the angiotensin-converting enzyme.

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.
Read the full methodologyA 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.
