HelloPharmacist Scorecard of L-Glutamine 1000 mg by Country Life
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. L-Glutamine is an amino acid your body naturally makes; it plays a role in immune function and digestive health.
Vitamin B6 (pyridoxine) is an essential vitamin involved in brain development, nervous-system function, and how your body metabolizes food. The tablet also contains several inactive ingredients — cellulose, stearic acid, silica, magnesium stearate, and a cellulose and glycerin coating — which are fillers, binders, and a coating to hold the tablet together and make it easier to swallow.
Does it work?
Strong evidence
L-Glutamine is effective for sickle cell disease and possibly effective for HIV/AIDS-related wasting, postoperative recovery, and recovery from critical illness (such as trauma). Vitamin B6 is effective for sideroblastic anemia (an uncommon blood disorder) and vitamin B6 deficiency itself, likely effective for high homocysteine levels (a cardiovascular risk marker), and possibly effective for pregnancy-related nausea and vomiting.
The evidence we hold doesn't establish effectiveness for other uses.
How safe is it?
Well-documented data
L-Glutamine is generally well tolerated in healthy adults. Common side effects include belching, bloating, constipation, diarrhea, flatulence, nausea, and headache.
People with kidney or liver disease should use it only under medical supervision. The safety data in pregnancy is rated likely safe, but there isn't enough information to know if it's safe during breastfeeding — talk with your doctor or pharmacist for personalized advice.
Vitamin B6 is well tolerated at doses under 100 mg daily. High doses over time can damage nerves (sensory neuropathy), especially doses exceeding 1000 mg daily or cumulative doses of 1000 grams or more, though nerve damage can occur at lower doses too.
Common side effects include headache, nausea, heartburn, and loss of appetite. In pregnancy, vitamin B6 is likely safe but possibly unsafe — your doctor should advise.
It's likely safe during breastfeeding.
Meds to double-check
Moderate interaction found
Before taking this product, have your doctor or pharmacist check if you're on anticonvulsants (phenytoin, phenobarbital, or others), antihypertensive drugs (blood pressure medications), amiodarone, or levodopa by itself — all have moderate to moderate-level interactions with vitamin B6 in this supplement. The vitamin B6 dose in this product is 1000 mg, which is considered high and carries a higher risk for the interactions listed above.
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.
If you have sickle cell disease or HIV-related wasting, L-Glutamine may help; if you have a vitamin B6 deficiency or high homocysteine, the B6 in this product targets that. Anyone with kidney or liver disease, or taking anticonvulsants, blood pressure medications, amiodarone, or levodopa should clear this with their own doctor or pharmacist before starting.

L-Glutamine 1000 mg by Country Life Drug Interactions
HelloPharmacist Interaction Report
L-Glutamine 1000 mg by Country Life contains two active ingredients, and one of them — vitamin B6 — interacts with medications.
The most serious concern is with anticonvulsants (seizure medications): vitamin B6 at high doses may reduce the blood levels and effectiveness of phenytoin (Dilantin) and phenobarbital (Luminal), possibly by speeding up how your body metabolizes them.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 also has moderate interactions with antihypertensive drugs (blood pressure medications), where it might add to their blood-pressure-lowering effect. It can theoretically increase the skin-sensitivity side effect from amiodarone (Cordarone), a heart rhythm medication.
Additionally, if you take levodopa alone for Parkinson's disease, vitamin B6 may reduce its effectiveness — though this doesn't happen if you're on the combination product carbidopa-levodopa (Sinemet). Vitamin B6 has a minor interaction with levodopa when taken by itself.
L-Glutamine itself has one documented moderate interaction: it may theoretically work against anticonvulsant medications, though this hasn't been reported in humans yet. We hold no interaction data for several of the inactive ingredients in this product.
Altogether, these interactions span 249 individual medications. Before you start this supplement, run your exact medications through the interaction checker below, especially if you take seizure medications, blood pressure drugs, amiodarone, or levodopa.

For each ingredient in L-Glutamine 1000 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-Glutamine
Anticonvulsants
Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.
