HelloPharmacist Scorecard of Extra Vitamin E Formula 400 IU by CATALO
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
Partial disclosure
This softgel contains 2 active ingredients: sodium and vitamin E (natural form). Vitamin E is a fat-soluble antioxidant your body needs in small amounts; sodium is an electrolyte that helps regulate fluid balance and nerve function.
The product also contains inactive ingredients—gelatin (the softgel shell), glycerin, and soybean oil—that serve as fillers and carriers.
Does it work?
Moderate evidence
The vitamin E in this product is Effective for treating vitamin E deficiency itself and for ataxia with vitamin E deficiency (AVED), a rare inherited disorder. It's rated Possibly Effective for Alzheimer disease, beta-thalassemia, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and intracranial hemorrhage.
Sodium's effectiveness is rated Likely Effective for cystic fibrosis and Possibly Effective for amphotericin B nephrotoxicity (kidney damage from an antifungal drug), but there isn't enough reliable evidence to rate it for bipolar disorder or congestive heart failure.
How safe is it?
Well-documented data
Vitamin E from food and normal amounts in supplements is generally well tolerated. However, high-dose long-term supplements—especially at or above 400 IU daily—may increase your risk of bleeding, including rare serious bleeds like hemorrhagic stroke.
Sodium is essential in small amounts, but too much raises blood pressure and strains your heart; the safety data advises against sodium supplements or very high intake without medical guidance. Normal dietary amounts of both are fine.
In pregnancy, vitamin E is rated Possibly Safe, but sodium's rating is mixed—Likely Safe in pregnancy but Possibly Unsafe in lactation, so talk with your doctor or pharmacist if you're pregnant or breastfeeding before taking this product.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (warfarin especially), blood pressure medications, lithium, corticosteroids, chemotherapy, or any sodium-containing drugs. Vitamin E at this dose can raise bleeding risk with anticoagulants, and sodium can interfere with blood pressure control and lithium levels—all Moderate severity concerns.
The bottom line
Scorecard at a glancePartially disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is most appropriate if you have a documented vitamin E deficiency or a condition like AVED and your doctor has approved it. If you take blood thinners, blood pressure medication, lithium, corticosteroids, or chemotherapy drugs, you should clear this with your own doctor or pharmacist first—the sodium and vitamin E both carry interaction risks.
Pregnant or breastfeeding? Check with your healthcare provider about whether this is right for you.

Extra Vitamin E Formula 400 IU by CATALO Drug Interactions
HelloPharmacist Interaction Report
CATALO's Extra Vitamin E Formula 400 IU interacts with medications through both its sodium and vitamin E content.
The most serious interaction is between vitamin E and blood thinners (anticoagulants) and antiplatelet drugs — at this dose of 400 IU, vitamin E can increase bleeding risk, and the concern is particularly sharp if you're also taking warfarin, which together may raise your bleeding risk significantly.
Read the full breakdown — every affected drug type, severity by severity
Sodium in this product can reduce how well blood pressure drugs (antihypertensives) work, and it may trigger dangerously high sodium levels (hypernatremia) if you're taking corticosteroids, the bipolar medication lithium, didanosine (an HIV drug), sodium phosphate (a bowel-prep agent), tolvaptan, or other sodium-containing medications. All of these interactions are Moderate in severity.
Vitamin E also interacts with several chemotherapy and cancer drugs—alkylating agents and antitumor antibiotics—where its antioxidant effect might blunt their effectiveness. It can also speed up how your body clears certain drugs metabolized by the liver enzyme CYP3A4, potentially lowering their levels.
Taking it alongside niacin may reduce niacin's beneficial effect on HDL cholesterol. Altogether, these interactions span 921 individual medications.
Use the medication checker on this page to look up any prescriptions, especially blood thinners, blood pressure medications, lithium, chemotherapy, or corticosteroids. If you take any of those, confirm with your own doctor or pharmacist before starting this product.

For each ingredient in Extra Vitamin E Formula 400 IU 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 E, Natural
Alkylating Agents
Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of alkylating agents.
There's concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin E have on chemotherapy. Advise patients to consult their oncologist before using vitamin E supplements, especially in high doses.
Anticoagulant/Antiplatelet Drugs
Concomitant use of vitamin E and anticoagulant or antiplatelet agents might increase the risk of bleeding.
Vitamin E seems to inhibit of platelet aggregation and antagonize the effects of vitamin K-dependent clotting factors. These effects appear to be dose-dependent, and are probably only likely to be clinically significant with doses of at least 800 units daily. Mixed tocopherols, such as those found in food, might have a greater antiplatelet effect than alpha-tocopherol. RRR alpha-tocopherol (natural vitamin E) 1000 IU daily antagonizes vitamin K-dependent clotting factors. Advise patients to avoid high doses of vitamin E, especially in people with low vitamin K intake or other risk factors for bleeding.
Antitumor Antibiotics
Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of antitumor antibiotics.
There's concern that antioxidants could reduce the activity of antitumor antibiotic drugs such as doxorubicin, which generate free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin E have on chemotherapy involving antitumor antibiotics. Advise patients to consult their oncologist before using vitamin E supplements, especially in high doses.
Cyclosporine (Neoral, Sandimmune)
A specific form of vitamin E might increase absorption and levels of cyclosporine.
There is some evidence that one specific formulation of vitamin E (D-alpha-tocopheryl-polyethylene glycol-1000 succinate, TPGS, tocophersolan, Liqui-E) might increase absorption of cyclosporine. This vitamin E formulation forms micelles which seems to increase absorption of cyclosporine by 40% to 72% in some patients. However, this interaction is unlikely to occur with the usual forms of vitamin E.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, vitamin E might induce metabolism of CYP3A4, possibly reducing the levels CYP3A4 substrates.
Vitamin E appears to bind with the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of vitamin E and other drugs affected by these enzymes.
Selumetinib (Koselugo)
Taking selumetinib with vitamin E can result in a total daily dose of vitamin E that exceeds safe limits and therefore might increase the risk of bleeding.
Selumetinib contains 48-54 IU vitamin E per capsule. The increased risk of bleeding with vitamin E appears to be dose-dependent. Be cautious when using selumetinib in combination with supplemental vitamin E, especially in patients at higher risk of bleed, such as those with chronic conditions and those taking antiplatelet drugs.
Warfarin (Coumadin)
Using vitamin E with warfarin might increase the risk of bleeding.
Due to interference with production of vitamin K-dependent clotting factors, use of more than 400 IU of vitamin E daily with warfarin might increase prothrombin time (PT), INR, and the risk of bleeding,. At a dose of 1000 IU per day, vitamin E can antagonize vitamin K-dependent clotting factors even in people not taking warfarin. Limited clinical evidence suggests that doses up to 1200 IU daily may be used safely by patients taking warfarin, but this may not be applicable in all patient populations.
Niacin
Vitamin E might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises high-density lipoprotein (HDL) cholesterol levels in people with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50%. Vitamin E alone combined with a statin does not seem to decrease HDL levels. It is not known whether the adverse effect on HDL is due to one of the other antioxidants or to the combination. It also is not known whether it will occur in other patient populations.
Sodium
Antihypertensive Drugs
Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.
Corticosteroids
Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.
Didanosine (Videx)
Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.
Lithium
Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.
Sodium Phosphates
Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.
Sodium-Containing Drugs
Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.
Tolvaptan (Samsca)
Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.
