Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Permatrol contains five active ingredients. Vitamin E supports the body's antioxidant defenses and is essential for vitamin E deficiency and related conditions.

Gamma oryzanol is a plant compound studied for cholesterol and skin health. L-glutamine is an amino acid particularly important in critical illness and sickle cell disease.

N-acetyl glucosamine (NAG) is a form of glucosamine used primarily for joint and skin health. Lactobacillus acidophilus CUL-60 is a beneficial probiotic bacterium that supports gut and digestive function.

The capsule also contains magnesium stearate and other inactive ingredients as binders and fillers.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Joint and digestive health support.
  • We looked for evidence on: Antibiotic-associated diarrhea, Diarrhea, Cartilage support, Gut barrier function, Intestinal permeability.
  • The strongest evidence on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Antibiotic-associated diarrhea (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Ineffective" for Radiation-induced diarrhea.
  • Also on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Radiation-induced diarrhea, Rotaviral diarrhea, Travelers' diarrhea.

Vitamin E is effective for treating vitamin E deficiency and a rare condition called AVED (ataxia with vitamin E deficiency), and possibly effective for Alzheimer disease, beta-thalassemia, G6PD deficiency, and intracranial hemorrhage. L-glutamine is effective for sickle cell disease and possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness.

N-acetyl glucosamine is likely effective for osteoarthritis but has insufficient evidence for aging skin, back pain, and other conditions. Lactobacillus acidophilus is possibly effective for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis, though it appears possibly ineffective for atopic disease.

Gamma oryzanol is possibly effective for high cholesterol (dyslipidemia), but the evidence is insufficient for athletic performance and eczema.

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 4 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin E is generally well-tolerated in usual dietary amounts, but high-dose long-term supplementation may raise the risk of bleeding and other serious effects including hemorrhagic stroke and cardiovascular complications. L-glutamine is generally well-tolerated in healthy adults, though people with kidney or liver disease should use it only under medical supervision; common side effects include belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting.

N-acetyl glucosamine is generally well-tolerated but carries rare reports of severe allergic reactions including anaphylaxis, and asthma exacerbation has been reported; common side effects include bloating, constipation, diarrhea, nausea, and heartburn. Lactobacillus acidophilus is generally well-tolerated in healthy adults, though rare cases of serious infection (bacteremia, sepsis, endocarditis) have been reported in vulnerable patients; mild gastrointestinal effects such as bloating, flatulence, and diarrhea can occasionally occur.

Gamma oryzanol is generally well-tolerated in studies, though long-term safety is not well established.

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.

Lactobacillus acidophilus CUL-601 drug type · 182 drugs

Antibiotic Drugs

Theoretically, taking Lactobacillus acidophilus with antibiotic drugs might decrease the effectiveness of L. acidophilus.
L. acidophilus preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and L. acidophilus preparations by at least two hours.

Likelihood Probable Evidence D
Lactobacillus acidophilus CUL-60 full monograph & interactions

N-Acetyl Glucosamine4 drug types · 170 drugs

Warfarin (Coumadin)

Glucosamine might increase the anticoagulant effects of warfarin and increase the risk of bruising and bleeding.
In two individual case reports, glucosamine/chondroitin combinations were associated with a significant increase in international normalized ratio (INR) in patients previously stabilized on warfarin. In one case, the increase in INR occurred only after tripling the dose of a glucosamine/chondroitin supplement from 500 mg/400 mg daily to 1500/1200 mg daily. Additionally, 20 voluntary case reports to the U.S. Food & Drug Administration (FDA) have linked glucosamine plus chondroitin with increased INR, bruising, and bleeding in patients who were also taking warfarin. There have also been 20 additional case reports to the World Health Organization (WHO) that link glucosamine alone to increased INR in patients taking warfarin. The mechanism of this interaction is unclear. Glucosamine is a small component of heparin, but is not thought to have anticoagulant activity; however, animal research suggests that it might have antiplatelet activity.

Likelihood Probable Evidence D
Topoisomerase Ii Inhibitors

Theoretically glucosamine may induce resistance to topoisomerase II inhibitors.
In vitro research suggests that glucosamine might induce resistance to etoposide (VP16, VePesid) and doxorubicin (Adriamycin) by reducing inhibition of topoisomerase II, an enzyme required for DNA replication in tumor cells. This effect has not been reported in humans.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

Acetaminophen might interfere with the activity of glucosamine sulfate by interacting with the sulfate portion.
Anecdotal reports suggest that adding glucosamine to an acetaminophen regimen might decrease pain control in patients with osteoarthritis. Some research suggests that the sulfate portion of glucosamine sulfate might contribute to its effect in osteoarthritis. Since acetaminophen metabolism requires sulfur and reduces serum sulfate concentrations, acetaminophen could theoretically interfere with the action of glucosamine sulfate. Conversely, the administration of sulfate could theoretically decrease the effectiveness of acetaminophen in sulfate-deficient people by increasing its clearance.

Likelihood Possible Evidence B
Antidiabetes Drugs

Despite initial concerns, it is unlikely that glucosamine will interfere with the effects of antidiabetes drugs.
In vitro and animal research has suggested that glucosamine might increase insulin resistance or decrease insulin production. This has raised concerns that taking glucosamine might worsen diabetes and decrease the effectiveness of diabetes drugs. However, clinical research suggests that glucosamine does not have adverse effects on blood glucose or glycated hemoglobin (HbA1C) in healthy, obese, or type 2 diabetes patients.

Likelihood Unlikely Evidence B
N-Acetyl Glucosamine full monograph & interactions

L-Glutamine1 drug type · 50 drugs

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.

Permatrol by BioCare: Common Questions

Does Permatrol by BioCare interact with any medications?
Yes. Based on its ingredients, Permatrol has a known interaction with 1,081 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Permatrol contains 5 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 Permatrol if I'm on warfarin or another blood thinner?
Not without checking first. N-acetyl glucosamine in this product may increase warfarin's anticoagulant effect and bleeding risk, and vitamin E carries a moderate interaction with anticoagulants and antiplatelet drugs for the same reason. Talk with your doctor or pharmacist before adding Permatrol to any blood-thinning medication.
Is Permatrol safe during pregnancy?
The data vary by ingredient. Vitamin E is possibly safe in pregnancy with dietary and prenatal amounts, but high-dose supplements should be avoided unless your doctor directs otherwise. L-glutamine is likely safe. N-acetyl glucosamine and gamma oryzanol have insufficient safety information and should be avoided in pregnancy. Talk with your doctor about whether Permatrol is right for you during pregnancy.
What are the most common side effects of L-glutamine in this product?
The most common side effects are gastrointestinal: belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting. Headache and musculoskeletal pain have also been reported. These tend to be mild and less frequent at lower doses.
Can I take Permatrol if I'm on antibiotics?
The Lactobacillus acidophilus in this product—live, active bacteria—may be killed by antibiotics taken at the same time, reducing its effectiveness. You can take them together, but separating your doses may help preserve the probiotic benefit. Ask your pharmacist about timing.
Does Permatrol actually help with osteoarthritis?
The N-acetyl glucosamine in Permatrol is likely effective for osteoarthritis, so there is meaningful evidence for that use. The other ingredients in the product are studied for different purposes, so whether Permatrol as a whole works for your osteoarthritis depends on your individual situation—talk it over with your doctor.
Is gamma oryzanol safe to take long-term?
Gamma oryzanol is generally well-tolerated in studies, but long-term safety is not well established. If you plan to take Permatrol long-term, check with your doctor about whether that's appropriate for you.
