HelloPharmacist Scorecard of Life Oil by aProven Product

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
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 8 of its 8 active ingredients.
  • “Total Unsaturated Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (688 mg) without saying how much of each component you get.

Life Oil contains 8 ingredients, of which vitamin A and vitamin E are the active ones. Vitamin A supports your vision, skin, and immune function, and is effective for preventing vitamin A deficiency.

Vitamin E is an antioxidant that protects cells and is effective for preventing vitamin E deficiency. The product also contains several fatty acids—linoleic acid, palmitoleic acid, oleic acid, alpha-linolenic acid, and sea buckthorn oil—which are omega and monounsaturated fats that play a role in skin health and heart health.

There are no inactive (filler) ingredients listed.

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Vitamin A deficiency — rated "Effective" (Vitamin A) (Natural Medicines).
  • On file: Vitamin E deficiency — rated "Effective" (Vitamin E) (Natural Medicines).
  • On file: Ataxia with vitamin E deficiency (AVED) — rated "Effective" (Vitamin E) (Natural Medicines).
  • On file: Aging skin — rated "Possibly Effective" (Vitamin A) (Natural Medicines).
  • On file: Alzheimer disease — rated "Possibly Effective" (Vitamin E) (Natural Medicines).

Vitamin A is established as effective for vitamin A deficiency and is possibly effective for oral leukoplakia, aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia. Vitamin E is established as effective for vitamin E deficiency and ataxia related to vitamin E deficiency, and is possibly effective for Alzheimer disease, beta-thalassemia, G6PD deficiency, and intracranial hemorrhage.

Oleic acid is possibly effective for high cholesterol and coronary heart disease. Sea buckthorn is possibly effective for burns, though it is rated possibly ineffective for eczema, and evidence is insufficient to rate it for aging skin, high triglycerides (dyslipidemia), or cancer.

The evidence, ingredient by ingredient Vitamin A Vitamin E Sea Buckthorn Oleic Acid

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin A is generally well-tolerated at recommended doses but is toxic at high doses because it builds up in your body, causing serious effects like headache, liver damage, and in rare cases pseudotumor cerebri (increased pressure in the brain). The safety data advises against high-dose vitamin A in pregnancy because it can cause birth defects; however, normal dietary and supplement amounts are appropriate.

Vitamin E is generally well-tolerated orally and topically, though long-term high doses may raise the risk of bleeding and, rarely, hemorrhagic stroke. Food amounts and prenatal vitamins are appropriate in pregnancy; high-dose supplements should be avoided unless directed by your doctor.

During breastfeeding, normal dietary amounts are fine, but check with your doctor before taking high-dose supplements. Sea buckthorn is generally well-tolerated as a food but has not been fully studied as a supplement; high doses may cause yellow staining of the skin.

Oleic acid from food is safe, but concentrated supplements are not well studied in pregnancy or breastfeeding.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 4 of the 4 matched ingredients can interact with medications — Sea Buckthorn, Vitamin E, Vitamin A, Oleic Acid.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; cancer treatments; diabetes medications.
  • For scale: 1,185 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Life Oil, double-check with your doctor or pharmacist if you take retinoids (vitamin A derivatives like tretinoin or isotretinoin) for acne or skin conditions—the major-severity risk of toxic vitamin A buildup is serious. If you take blood thinners (anticoagulants like warfarin or antiplatelet drugs like aspirin), blood pressure medications, antidiabetes drugs, liver-stress medications, tetracycline antibiotics, chemotherapy drugs, cyclosporine, or any medication processed by your liver, you'll need to confirm it's safe to combine with this product.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.

Life Oil may be worth considering if you're looking to support skin health and have a vitamin A or E deficiency, but you'll want to check your medications first—especially if you take blood thinners, retinoids, antibiotics, or drugs that affect the liver. Because this product can interact with a wide range of medications and contains vitamins that build up in your body at high doses, talk with your doctor or pharmacist before starting it.

Vitamin E8 drug types · 764 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Unlikely Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence A
Vitamin E full monograph & interactions

Vitamin A4 drug types · 387 drugs

Retinoids

Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.

Likelihood Possible Evidence C
Tetracycline Antibiotics

Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.

Likelihood Possible Evidence D
Vitamin A full monograph & interactions

Sea Buckthorn Oil2 drug types · 289 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, sea buckthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Clinical research suggests that sea buckthorn fruit extracts can inhibit platelet aggregation and adhesion to collagen and fibrinogen.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking sea buckthorn with antihypertensive drugs might increase the risk of hypotension.
Taking sea buckthorn appears to reduce blood pressure in some patients.

Likelihood Possible Evidence D
Sea Buckthorn Oil full monograph & interactions

Oleic Acid1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, oleic acid might increase the effects of antidiabetes drugs. Preliminary clinical research in patients with type 2 diabetes taking oral hypoglycemic drugs shows that eating a diet rich in oleic acid from olive oil decreases fasting blood glucose levels when compared to eating a diet rich in linoleic acid from sunflower oil. It is unknown if taking oleic acid supplements would have this effect or if this change is clinically significant. Until more is known, use caution. Dose adjustment may be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.

Life Oil by aProven Product: Common Questions

Does Life Oil by aProven Product interact with any medications?
Yes. Based on its ingredients, Life Oil has a known interaction with 1,184 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Life Oil contains 9 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take Life Oil if I'm pregnant?
Vitamin A safety data advises against high doses in pregnancy because they can cause birth defects, but normal dietary and recommended supplement amounts are appropriate—so it depends on the dose in this product. Vitamin E amounts from food and prenatal vitamins are fine in pregnancy. Because sea buckthorn and oleic acid haven't been well studied as concentrated supplements in pregnancy, talk with your doctor or pharmacist before taking Life Oil if you're pregnant to make sure the dose is right for you.
Is this product safe to use while breastfeeding?
Vitamin E from food is likely safe during breastfeeding, though high-dose supplements lack good safety data and you should check with your doctor first. Normal dietary amounts of oleic acid are considered safe. Sea buckthorn and linoleic acid don't have enough reliable safety data during breastfeeding, so ask your doctor or pharmacist before starting.
What is sea buckthorn oil in this product for?
Sea buckthorn oil is possibly effective for burns and contains fatty acids that may support skin and heart health. It's not well studied as a supplement, but it's generally well tolerated when taken by mouth—though high doses can cause yellow staining of the skin.
Can vitamin A in this product build up in my body and make me sick?
Yes. Vitamin A is fat-soluble, meaning your body stores it rather than clearing it easily, so it can build up over time. At doses below the safe upper limit (10,000 IU daily for adults), it's generally well tolerated. At higher doses, it can cause serious effects including fatigue, dry and peeling skin, hair loss, headache, and in rare cases liver damage or brain swelling. If you take this product, avoid other high-dose vitamin A supplements and ask your doctor or pharmacist about the total amount you're getting.
Does vitamin E in this product increase bleeding risk?
Vitamin E can theoretically increase bleeding risk, especially at high doses and especially if you take blood thinners, antiplatelet drugs, or other medications that affect clotting. The risk is dose-dependent—higher doses carry more concern. If you take any of these medications, talk with your doctor or pharmacist before starting Life Oil to make sure it's safe for you.
What fatty acids does Life Oil contain?
Life Oil contains linoleic acid (an omega-6 fat), palmitoleic acid, oleic acid (a monounsaturated fat), and alpha-linolenic acid (an omega-3 fat), along with sea buckthorn oil. These are all fats that support skin and heart health, though most come from food sources and are familiar parts of a normal diet.
