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, drawn from Singh's 2023 work showing taurine declines with age, is more preliminary at Grade C, so it is best treated as an interesting signal rather than a settled 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. 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
Additive blood-pressure lowering
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.

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.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
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.

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.

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.

Taurine tends to lower blood pressure on its own, and indapamide is a water tablet used to lower it.

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.

What this list does not say. Pairs not flagged here are not implicitly safe. They are either not yet in our database, or fall outside our inclusion scope. Use the checker below to surface any medication, and submit a missing item if you take something we have not catalogued.
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.

This page checks the pairs you enter. The personalised Distil report goes further:
- the same graded, cited interaction check across your whole stack, not just the pairs you thought to type in
- where your current routine may be leaving you short of your goals
- the evidence-backed compounds worth adding, and the ones worth dropping
It's a paid report: £79, or £49 for the first 25 customers. The interactions check is one section of it, and you can read a real one in full before you buy.
