What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 2 of its 16 active ingredients.
  • “Liver Cleanse” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “Fibrinolytic Enzyme blend” is a proprietary blend — the label doesn't break down how much of each component you get.
  • “Estromin Hormonal Support Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

FibroVera AHS contains 16 active ingredients, including digestive enzymes (papain, bromelain, serrapeptase, protease, and nattokinase), the mineral magnesium, the vitamin B6, the hormone precursor DHEA, and herbal extracts (milk thistle, dandelion powder, black cohosh, dong quai, and hyssop). It also includes gamma-linolenic acid, diindolylmethane, and 5-hydroxytryptophan.

Several proprietary blends are listed—the Liver Cleanse, Fibrinolytic Enzyme, and Estromin Hormonal Support Blend—whose individual components are named above. The product also contains inactive ingredients: cellulose, calcium caprylate, and maltodextrin.

Does it work?

Moderate 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
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: support healthy hormones and menstrual cycle comfort.
  • We looked for evidence on: Anxiety, Adrenal insufficiency, Premenstrual syndrome, Menstrual discomfort, Hot flashes, Mood changes.
  • The strongest evidence on file: Vitamin B6 is rated "Possibly Effective" for Premenstrual syndrome (PMS) (Natural Medicines).
  • Also on file: Magnesium is rated "Possibly Effective" for Premenstrual syndrome (PMS).
  • Also on file: Dhea is rated "Insufficient Reliable Evidence To Rate" for Adrenal insufficiency.

The evidence for what this product does is not established in our data. Most of its active ingredients—papain, bromelain, diindolylmethane, dandelion, serrapeptase, black cohosh, dong quai, protease, nattokinase, and 5-HTP—all have insufficient reliable evidence or insufficient evidence to establish effectiveness for their claimed uses.

Magnesium is effective for constipation, dyspepsia, and hypomagnesemia, and likely effective for hyperhomocysteinemia. Vitamin B6 is effective for sideroblastic anemia and vitamin B6 deficiency, and possibly effective for pregnancy-induced nausea.

We hold no effectiveness data for gamma-linolenic acid or hyssop.

The evidence, ingredient by ingredient Vitamin B6 Magnesium

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 14 of the 15 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 15 of 15.
  • General safety write-ups exist for 15 of 15.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most ingredients in this product are generally well tolerated at recommended doses. Papain may irritate the digestive tract and cause allergic reactions; concentrated papain and unripe papaya products should be avoided in pregnancy.

Bromelain is generally well tolerated short-term, though long-term safety is limited, and common side effects include diarrhea, flatulence, and gastric upset. Diindolylmethane is generally well tolerated short-term but can cause diarrhea, gas, headache, nausea, and rash.

Vitamin B6 is safe at normal amounts but high doses over time can harm nerves (sensory neuropathy). DHEA should be used only under medical guidance because it affects hormones; it commonly causes acne, headache, insomnia, and mood changes, and in women can cause masculinization symptoms.

Magnesium commonly causes diarrhea and gastrointestinal upset. Nattokinase has rare reports of hemorrhage.

Dong quai may increase bleeding risk and cause photosensitivity. Black cohosh is generally well tolerated short-term but rare liver concerns exist.

5-HTP commonly causes nausea, diarrhea, headache, and drowsiness. None of these ingredients should be used in pregnancy except magnesium (needed but use only under doctor guidance) and possibly vitamin B6 for morning sickness (doctor guidance required); dong quai, bromelain, dandelion, serrapeptase, black cohosh, diindolylmethane, DHEA, nattokinase, protease, and 5-HTP should be avoided in pregnancy.

Safety data during breastfeeding is insufficient or lacking for most ingredients; caution or avoidance is advised.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

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

Why this rating?
  • 13 of the 15 matched ingredients can interact with medications — Papain, Milk Thistle, Dhea, Dandelion, 5-htp, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications; lithium; Parkinson's medications.
  • For scale: 1,528 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.

If you take warfarin (Coumadin) or other blood thinners (anticoagulants) or antiplatelet drugs like aspirin or clopidogrel, do not start this product without checking first—dong quai and several other ingredients increase your bleeding risk. Also double-check if you take levodopa/carbidopa (Sinemet) for Parkinson's, diabetes medications, blood pressure drugs, or antidepressants.

No interactions are documented for hyssop or protease among the ingredients we could check.

Each ingredient & the kinds of drugs it affects

For each ingredient in FibroVera AHS 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.

Magnesium15 drug types · 295 drugs

Levodopa/Carbidopa (Sinemet)

Magnesium can reduce the bioavailability of levodopa/carbidopa.
Clinical research in healthy volunteers shows that taking magnesium oxide 1000 mg with levodopa 100 mg/carbidopa 10 mg reduces the area under the curve (AUC) of levodopa by 35% and of carbidopa by 81%. In vitro and animal research shows that magnesium produces an alkaline environment in the digestive tract, which might lead to degradation and reduced bioavailability of levodopa/carbidopa.

Likelihood Probable Evidence B
Aminoglycoside Antibiotics

Concomitant use of aminoglycoside antibiotics and magnesium can increase the risk for neuromuscular weakness.
Both aminoglycosides and magnesium reduce presynaptic acetylcholine release, which can lead to neuromuscular blockade and possible paralysis. This is most likely to occur with high doses of magnesium given intravenously.

Likelihood Possible Evidence D
Antacids

Use of acid reducers may reduce the laxative effect of magnesium oxide.
A retrospective analysis shows that, in the presence of H2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs), a higher dose of magnesium oxide is needed for a laxative effect. This may also occur with antacids. Under acidic conditions, magnesium oxide is converted to magnesium chloride and then to magnesium bicarbonate, which has an osmotic laxative effect. By reducing acidity, antacids may reduce the conversion of magnesium oxide to the active bicarbonate salt.

Likelihood Possible Evidence D
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Magnesium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after magnesium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Magnesium can decrease absorption of bisphosphonates.
Cations, including magnesium, can decrease bisphosphonate absorption. Advise patients to separate doses of magnesium and these drugs by at least 2 hours.

Likelihood Probable Evidence B
Calcium Channel Blockers

Magnesium can have additive effects with calcium channel blockers, although evidence is conflicting.
Magnesium inhibits calcium entry into smooth muscle cells and may therefore have additive effects with calcium channel blockers. Severe hypotension and neuromuscular blockades may occur when nifedipine is used with intravenous magnesium, although some contradictory evidence suggests that concurrent use of magnesium with nifedipine does not increase the risk of neuromuscular weakness. High doses of magnesium could theoretically have additive effects with other calcium channel blockers.

Likelihood Possible Evidence D
Digoxin

Magnesium salts may reduce absorption of digoxin.
Clinical evidence suggests that treatment with oral magnesium hydroxide or magnesium trisilicate reduces absorption of digoxin from the intestines. This may reduce the blood levels of digoxin and decrease its therapeutic effects.

Likelihood Possible Evidence B
Potassium-Sparing Diuretics

Potassium-sparing diuretics decrease excretion of magnesium, possibly increasing magnesium levels.
Potassium-sparing diuretics also have magnesium-sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics. Theoretically, increased magnesium levels could result from concomitant use of potassium-sparing diuretics and magnesium supplements.

Likelihood Probable Evidence D
Quinolone Antibiotics

Magnesium decreases absorption of quinolones.
Magnesium can form insoluble complexes with quinolones and decrease their absorption. Advise patients to take these drugs at least 2 hours before, or 4 to 6 hours after, magnesium supplements.

Likelihood Probable Evidence D
Skeletal Muscle Relaxants

Parenteral magnesium alters the pharmacokinetics of skeletal muscle relaxants, increasing their effects and accelerating the onset of effect.
Parenteral magnesium shortens the time to onset of skeletal muscle relaxants by about 1 minute and prolongs the duration of action by about 2 minutes. Magnesium potentiates the effects of skeletal muscle relaxants by decreasing calcium-mediated release of acetylcholine from presynaptic nerve terminals, reducing postsynaptic sensitivity to acetylcholine, and having a direct effect on the membrane potential of myocytes. Magnesium also has vasodilatory actions and increases cardiac output, allowing a greater amount of muscle relaxant to reach the motor end plate. A clinical study found that low-dose rocuronium (0.45 mg/kg), when given after administration of magnesium 30 mg/kg over 10 minutes, has an accelerated onset of effect, which matches the onset of effect seen with a full-dose rocuronium regimen (0.6 mg/kg). In another clinical study, onset times for rocuronium doses of 0.3, 0.6, and 1.2 mg/kg were 86, 76, and 50 seconds, respectively, when given alone, but were reduced to 66, 44, and 38 seconds, respectively, when the doses were given after a 15-minute infusion of magnesium sulfate 60 mg/kg. Giving intraoperative intravenous magnesium sulfate, 50 mg/kg loading dose followed by 15 mg/kg/hour, reduces the onset time of rocuronium, enhances its clinical effects, reduces the dose of intraoperative opiates, and prolongs the spontaneous recovery time. It does not affect the activity of subsequently administered neostigmine.

Likelihood Probable Evidence A
Sulfonylureas

Magnesium increases the systemic absorption of sulfonylureas, increasing their effects and side effects.
Clinical research shows that administration of magnesium hydroxide with glyburide increases glyburide absorption, increases maximal insulin response by 35-fold, and increases the risk of hypoglycemia, when compared with glyburide alone. A similar interaction occurs between magnesium hydroxide and glipizide. The mechanism of this effect appears to be related to the elevation of gastrointestinal pH by magnesium-based antacids, increasing solubility and enhancing absorption of sulfonylureas.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Magnesium decreases absorption of tetracyclines.
Magnesium can form insoluble complexes with tetracyclines in the gut and decrease their absorption and antibacterial activity. Advise patients to take these drugs 1 hour before or 2 hours after magnesium supplements.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, magnesium may have antiplatelet effects, but the evidence is conflicting.
In vitro evidence shows that magnesium sulfate inhibits platelet aggregation, even at low concentrations. Some preliminary clinical evidence shows that infusion of magnesium sulfate increases bleeding time by 48% and reduces platelet activity. However, other clinical research shows that magnesium does not affect platelet aggregation, although inhibition of platelet-dependent thrombosis can occur.

Likelihood Unlikely Evidence B
Gabapentin (Neurontin)

Gabapentin absorption can be decreased by magnesium.
Clinical research shows that giving magnesium oxide orally along with gabapentin decreases the maximum plasma concentration of gabapentin by 33%, time to maximum concentration by 36%, and area under the curve by 43%. Advise patients to take gabapentin at least 2 hours before, or 4 to 6 hours after, magnesium supplements.

Likelihood Unlikely Evidence B
Sevelamer (Renagel, Renvela)

Sevelamer may increase serum magnesium levels.
In patients on hemodialysis, sevelamer use was associated with a 0.28 mg/dL increase in serum magnesium. The mechanism of this interaction remains unclear.

Likelihood Possible Evidence B
Magnesium full monograph & interactions

Vitamin B65 drug types · 210 drugs

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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

FibroVera AHS by Arthur Andrew Medical: Common Questions

Does FibroVera AHS by Arthur Andrew Medical interact with any medications?
Yes. Based on its ingredients, FibroVera AHS has a known interaction with 1,527 medications, including 8 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
FibroVera AHS 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 this if I'm pregnant or breastfeeding?
Most ingredients in this product are not safe in pregnancy or breastfeeding. Avoid dong quai, bromelain, dandelion, serrapeptase, black cohosh, diindolylmethane, DHEA, nattokinase, protease, and 5-HTP. Magnesium is needed in pregnancy but use supplements only under your doctor's guidance, and vitamin B6 can be used for morning sickness only with doctor approval. Talk to your pharmacist or doctor before using this product if you're pregnant or nursing.
What's papain and what does it do?
Papain is a protease enzyme derived from papaya. It breaks down proteins and is used in this product as a digestive aid. We don't have reliable evidence that it works for any specific condition. It can irritate your digestive tract, cause allergic reactions, and may interact with blood thinners like warfarin.
Will this help with pain or inflammation?
The product contains several enzymes (bromelain, serrapeptase, nattokinase) and herbal ingredients that are sometimes used for these purposes, but we don't have reliable evidence that they work. Their effectiveness has not been established in our data.
Can this cause side effects?
Yes. Common side effects from the ingredients include nausea, diarrhea, headache, gas, and gastrointestinal upset. Allergic reactions are possible, especially to the enzymes. More serious but rare side effects include bleeding (from nattokinase or dong quai) and liver concerns (from black cohosh). If you notice unusual bruising, bleeding, nausea, or abdominal pain, stop and contact your pharmacist.
Is magnesium in this product safe?
Magnesium is generally well tolerated at normal amounts, but this product may also contain other ingredients that interact with it or with your medications. The dose of magnesium in this multi-ingredient blend is not specified on your facts, so ask your pharmacist what you're actually getting. Magnesium can reduce absorption of several antibiotics and other drugs, so timing matters.
Does DHEA in this product affect hormones?
Yes. DHEA is a hormone precursor and can cause hormonal side effects like acne, mood changes, irregular periods (in women), and masculinization symptoms. It should be used only under medical guidance and is not safe in pregnancy or while breastfeeding. If you have a history of hormone-sensitive cancer or take estrogen therapy, check with your pharmacist first.
