HelloPharmacist Scorecard of Flax Oil with B6 by SP Standard Process
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 softgel delivers 2 active ingredients: vitamin B6 and flaxseed oil. Vitamin B6 is a B-complex vitamin that plays a role in nerve function and metabolism.
Flaxseed oil is a plant-based oil rich in alpha-linolenic acid, an omega-3 fatty acid. The inactive ingredients include gelatin (capsule material), water, glycerine, beeswax, and pyridoxine hydrochloride (a form of B6).
Does it work?
Moderate evidence
The evidence for B6 is stronger: it's effective for sideroblastic anemia and B6 deficiency, likely effective for high homocysteine levels, and possibly effective for pregnancy-related nausea and vomiting (though only under a doctor's guidance). Flaxseed oil, however, shows weak or no benefit: the data rates it possibly ineffective for obesity, rheumatoid arthritis, bipolar disorder, and high cholesterol.
The evidence we hold doesn't support its use for these conditions.
How safe is it?
Well-documented data
Vitamin B6 is well tolerated at doses under 100 mg daily, though at higher doses — especially above 1,000 mg daily or with cumulative intake of 1,000 grams or more — it can cause nerve damage (sensory neuropathy). Common milder side effects include headache, nausea, and loss of appetite.
Flaxseed oil is generally well tolerated by most adults, though a small number of people report changes in bowel habits, dry mouth, or indigestion at typical doses; high doses (30 grams daily and above) have been linked to loose stools. There's limited safety data for flaxseed oil in breastfeeding, so check with your doctor before use.
Meds to double-check
Moderate interaction found
Check these medication types with us before starting: antihypertensive drugs (blood pressure medications — both ingredients may lower pressure further), seizure medications like phenobarbital and phenytoin (B6 may reduce their effectiveness at high doses), blood thinners or antiplatelet drugs (flaxseed oil may increase bleeding risk), ezetimibe (Zetia) for cholesterol (flaxseed oil blocks its absorption), amiodarone (Cordarone) for heart rhythm (B6 may worsen sun sensitivity), and levodopa for Parkinson's (B6 may reduce its effect if you're not also taking carbidopa).
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you take blood pressure medications, seizure drugs, blood thinners, or levodopa, run this product through the checker below with your exact medications before you start — B6 and flaxseed oil both interact with these. The B6 in here is most useful if you have a documented deficiency or certain anemias; the flaxseed oil evidence for its marketed uses is weak.

Flax Oil with B6 by SP Standard Process Drug Interactions
HelloPharmacist Interaction Report
Flax Oil with B6 by SP Standard Process contains two active ingredients, and together they interact with medications in several important ways.
The most serious concern is vitamin B6's interaction with blood pressure medications (antihypertensives) and seizure medications: B6 may add to the blood-pressure-lowering effect of antihypertensive drugs, and high doses can reduce how well seizure drugs like phenobarbital and phenytoin work by speeding up how your body clears them. Altogether, these interactions span 328 individual medications.
Read the full breakdown — every affected drug type, severity by severity
Flaxseed oil adds its own moderate interactions: it may boost the blood-pressure-lowering effect of antihypertensive drugs, increase bleeding risk if you're on blood thinners (anticoagulants) or antiplatelet drugs like aspirin, and it can block absorption of the cholesterol drug ezetimibe (Zetia). Vitamin B6 also has a minor interaction with levodopa (a Parkinson's drug) — B6 can speed up how your body metabolizes it and reduce its effect, but this doesn't happen if you're taking it with carbidopa (as in Sinemet).
Amiodarone (Cordarone), a heart rhythm drug, may have increased photosensitivity (sun sensitivity) when combined with B6. Use the medication checker below with your exact prescriptions before starting this product.

Flaxseed Oil
Anticoagulant/Antiplatelet Drugs
Theoretically, using flaxseed oil in combination with anticoagulant or antiplatelet drugs might have additive effects and increase the risk of bleeding.
Small clinical studies show that consuming flaxseed oil might decrease platelet aggregation and increase bleeding time.
Antihypertensive Drugs
Theoretically, combining flaxseed oil with other antihypertensive drugs might have additive effects and increase the risk of hypotension.
Some clinical evidence suggests that long-term consumption of flaxseed oil can modestly lower systolic and diastolic blood pressure, while other clinical research shows no effect.
Ezetimibe (Zetia)
Concomitant use of flaxseed oil and ezetimibe reduces the absorption of alpha-linolenic acid from flaxseed oil.
In one clinical study, concomitant consumption of ezetimibe 10 mg daily with flaxseed oil 2 grams providing 1 gram of alpha-linolenic acid daily blocked the absorption of alpha-linolenic acid, resulting in an overall reduction in alpha-linolenic plasma levels from baseline.
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.
