HelloPharmacist Scorecard of L-Taurine 500 mg by The Vitamin Shoppe
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains 2 active ingredients: vitamin B6 and taurine, each playing different roles in the body. Vitamin B6 (pyridoxine) is a B vitamin that helps with nerve function, blood cell formation, and metabolism.
Taurine is an amino acid your body makes naturally; it supports heart function, muscle contraction, and eye health. The capsule also contains inactive ingredients — rice flour, gelatin, and water — which help deliver the active ingredients.
Does it work?
Strong evidence
Vitamin B6 is Effective for sideroblastic anemia (a blood disorder) and B6 deficiency itself, Likely Effective for lowering homocysteine (a blood marker), and Possibly Effective for pregnancy-related nausea. Taurine is Possibly Effective for hepatitis and congestive heart failure (CHF), though the evidence isn't yet conclusive.
The data shows taurine as Possibly Ineffective for weight loss. For other uses beyond these, we don't hold effectiveness ratings in our data.
How safe is it?
Well-documented data
Vitamin B6 at normal doses and amounts from food is generally well tolerated, but high doses over time can damage nerves (a condition called sensory neuropathy), particularly at intakes exceeding 1,000 mg daily or cumulative totals of 1,000 grams or more. Common side effects at any dose include headache, nausea, and loss of appetite.
Taurine is generally well tolerated in typical doses for up to a year, though long-term safety is less certain. The most common side effects are constipation, diarrhea, and heartburn.
In rare cases, people allergic to sulfa drugs or sulfites may have a hypersensitivity reaction to taurine. Serious cardiovascular effects reported in case reports involved energy drinks with taurine and other ingredients, so it's unclear whether taurine alone was responsible.
Meds to double-check
Moderate interaction found
If you take blood pressure medications (antihypertensive drugs), check with your pharmacist first — both vitamin B6 and taurine may lower your blood pressure further. Similarly, check before taking lithium (a mood stabilizer), since taurine might raise its levels.
If you take amiodarone for heart rhythm, phenobarbital or phenytoin for seizures, or levodopa (without carbidopa) for Parkinson's, discuss this product with your pharmacist, as vitamin B6 may interfere with how well they work.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This product combines two ingredients with established but different roles — vitamin B6 for certain anemias and B6 deficiency, and taurine for possible heart and liver support. However, both ingredients interact with blood pressure medications and other drugs, and vitamin B6 in particular requires caution if you take seizure or Parkinson's medications.
Before starting, check with your doctor or pharmacist whether it's compatible with your prescriptions.

HelloPharmacist Interaction Report
L-Taurine 500 mg by The Vitamin Shoppe contains two active ingredients — vitamin B6 and taurine — and both have documented interactions with medications.
The most serious concern is vitamin B6's Moderate-severity interaction with antihypertensive drugs (blood pressure medications), where B6 may add to their blood-pressure-lowering effect.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 also interacts Moderately with amiodarone (a heart rhythm medication), where it may worsen light sensitivity; with phenobarbital and phenytoin (seizure medications), where high doses may reduce their effectiveness; and Minor with levodopa (a Parkinson's medication), though this only happens when levodopa is taken without carbidopa. Taurine carries Moderate interactions with antihypertensive drugs — it may lower blood pressure further — and with lithium (a mood stabilizer), where it might raise lithium levels in your blood.

For each ingredient in L-Taurine 500 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Vitamin B6
Amiodarone (Cordarone)
Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.
Antihypertensive Drugs
Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.
Phenobarbital (Luminal)
High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.
Phenytoin (Dilantin)
High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.
Levodopa
Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.
Taurine
Antihypertensive Drugs
Theoretically, taurine might increase the risk of hypotension when taken with antihypertensive drugs.
Some clinical evidence suggests that taurine can reduce both systolic and diastolic blood pressure.
Lithium
Theoretically, taurine might reduce excretion and increase plasma levels of lithium.
Taurine is thought to have diuretic properties, which might reduce the excretion of lithium.
