HelloPharmacist Scorecard of L-Taurine 500 mg by DC
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 supplement contains 2 active ingredients: vitamin B6 and L-taurine. Vitamin B6 is a water-soluble B vitamin involved in nerve function, red blood cell formation, and immune support.
L-Taurine is an amino acid found naturally in the body and in animal foods; your body uses it for heart and eye function, among other roles. The capsule also contains inactive ingredients—gelatin, vegetable cellulose, vegetable magnesium stearate, and silica—which help form and fill the capsule.
Does it work?
Strong evidence
The evidence for this product's ingredients varies by condition. Vitamin B6 is effective for sideroblastic anemia and B6 deficiency, likely effective for elevated homocysteine (a heart risk factor), and possibly effective for pregnancy-related nausea and vomiting.
L-Taurine is possibly effective for hepatitis and congestive heart failure, but possibly ineffective for weight loss. We hold no effectiveness data for L-taurine 500 mg as a combined product for any specific use.
How safe is it?
Well-documented data
Vitamin B6 is well tolerated at doses under 100 mg daily. The most common side effects are headache, nausea, heartburn, and abdominal pain.
High doses (above 1,000 mg daily or very high cumulative doses) can rarely cause nerve damage (sensory neuropathy), though this can happen at lower doses too. L-Taurine is generally well tolerated short-term in healthy adults, with the most common effects being constipation, diarrhea, or indigestion.
Serious side effects are rare. Some people, especially those with a history of allergies to sulfonamides or sulfites, have had allergic reactions to taurine supplements.
Long-term safety data for supplement doses of taurine are limited.
Meds to double-check
Moderate interaction found
If you take blood-pressure-lowering drugs, seizure medications (phenobarbital or phenytoin), the heart drug amiodarone, levodopa for Parkinson's disease (especially without carbidopa), or lithium, double-check with your pharmacist or doctor before taking this product. All of these interactions are documented Moderate or Minor severity.
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 vitamin B6 and L-taurine, each with established but modest evidence for certain uses. Both ingredients have documented interactions with blood-pressure medications and other drugs—vitamin B6 has additional concerns with seizure and Parkinson's medications.
Before starting, search your medications on this page, and talk with your own doctor or pharmacist about whether it's right for you and any dose adjustments needed.

L-Taurine 500 mg by DC Drug Interactions
HelloPharmacist Interaction Report
L-Taurine 500 mg by DC contains vitamin B6 and L-taurine, both of which interact with medications.
The most serious concern is vitamin B6's Moderate-severity effect on antihypertensive drugs—it may add to their blood-pressure-lowering action, potentially dropping your pressure too far.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 also interacts Moderately with the heart rhythm drug amiodarone (Cordarone), possibly worsening sun sensitivity; with the seizure medications phenobarbital (Luminal) and phenytoin (Dilantin), where high doses can reduce their levels and effectiveness; and Minorly with levodopa for Parkinson's disease, though this risk doesn't apply if you take it with carbidopa.
L-Taurine adds Moderate-level concerns: it may enhance antihypertensive drugs' blood-pressure effects further, and it might reduce how your kidneys clear lithium, raising lithium levels dangerously. Altogether, these interactions span 211 individual medications.

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.
L-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.
